Animal classification by Emma Huddleston( Book )

3 editions published between 2021 and 2022 in English and held by 162 WorldCat member libraries worldwide

Animals are all related. Some are more closely related than others. Scientists group them based on how they are related. Animal Classification looks at how scientists group animals, from least to most specific
An atlas of book lung fine structure in the order Scorpiones (Arachnida) by Carsten Kamenz( Book )

4 editions published in 2008 in English and held by 39 WorldCat member libraries worldwide

The fine structure of the book lungs of scorpions is diverse and phylogenetically informative, but has not been comprehensively investigated across the major lineages of the order. In this contribution, we present a fully illustrated atlas of the variation in book lung fine structure among 200 exemplars from 100 genera and 18 families of extant scorpions. We document variation in the surface sculpturing of the respiratory lamellae, the edges of the lamellae in the atrial chamber, and the posterior valvelike edges of the spiracles. These data provide insights into the phylogenetic relationships among Recent scorpions at several branches of the tree
Systematic revision of the troglomorphic North American scorpion family Typhlochactidae (Scorpiones, Chactoidea) by Valerio Vignoli( Book )

6 editions published in 2009 in English and held by 31 WorldCat member libraries worldwide

The scorpion family Typhlochactidae Mitchell, 1971, endemic to eastern Mexico, comprises nine troglomorphic species specialized for life in hypogean and endogean habitats. Due to their cryptic ecology, inaccessible habitat, and apparently low population density, Typhlochactidae are poorly known. Only 29 specimens have been collected in 40 years. Four species are known from a single specimen, two species are known only from the male and three only from the female. We provide an illustrated revision of the family based on a reexamination of most specimens in the world’s collections, including new specimens collected after the original descriptions and older specimens not previously described. Based on results of a recent cladistic analysis, Typhlochactidae are elevated, for the first time, from their former rank as subfamily, first of Chactidae and, more recently, of Superstitioniidae. Alacraninae, new subfamily is created to accommodate Alacran Francke, 1982. Stygochactas, new genus, is created to accommodate Typhlochactas granulosus Sissom and Cokendolpher, 1998 in a new combination. Sotanochactas Francke, 1986, Stygochactas and Typhlochactas Mitchell, 1971 are retained in subfamily Typhlochactinae Mitchell, 1971. Diagnoses of the family and subfamilies are presented, followed by a key to the genera and species, revised diagnoses of the genera, revised diagnoses and descriptions, tabulated meristic data, and distribution maps of the species. Descriptions and diagnoses are illustrated with ultraviolet fluorescence and visible light photographs, providing a visual atlas to the morphology of these remarkable scorpions. A review of their taxonomic history is provided, the importance of trichobothriotaxy for their systematics discussed, and several misconceptions in the literature clarified
Discovery of the male of Parabuthus muelleri, and implications for the phylogeny of Parabuthus (Scorpiones, Buthidae) by Lorenzo Prendini( )

6 editions published in 2003 in English and held by 29 WorldCat member libraries worldwide

The male of Parabuthus muelleri Prendini, 2000 is described, based on a specimen discovered in the Alexis Harington Scorpion Collection (recently acquired by the American Museum of Natural History). This is only the third known specimen of P. muelleri. The holotype and paratype are both female. The male presents several character states, including the lobate condition of the pectinal proximal median lamella and pedipalp chelae that are not incrassate, that are uncommon in male Parabuthus Pocock, 1890. These character states, previously scored with missing entries in a cladistic character matrix for Parabuthus species, are now added and a reanalysis of Parabuthus phylogeny, resulting in new insights about the phylogenetic position of P. muelleri, is presented. Lectotypes are designated for four northeastern African species of Parabuthus
New South African flat rock scorpions (Liochelidae, Hadogenes) by Lorenzo Prendini( )

6 editions published in 2006 in English and held by 26 WorldCat member libraries worldwide

Two new flat rock scorpions, both endemic to South Africa, are described in the bicolor group of Hadogenes Kraepelin, 1894: H. polytrichobothrius n.sp.; H. soutpansbergensis n.sp. Both occupy discrete distributional ranges, allopatric with the other three species in the bicolor group: H. bicolor Purcell, 1899; H. longimanus Prendini, 2001; H. newlandsi Prendini, 2001. The distributions of the five species in the group are mapped, and a key provided for their identification
New records and observations on the natural history of Lisposoma elegans and L. josehermana (Scorpiones, Bothriuridae) by Lorenzo Prendini( )

5 editions published in 2005 in English and held by 26 WorldCat member libraries worldwide

The endemic Namibian scorpion genus Lisposoma Lawrence, 1928 is a basal African lineage of the Gondwanan family Bothriuridae Simon, 1880. The natural history of Lisposoma remains poorly known. This contribution provides new records and observations on the natural history of Lisposoma elegans Lawrence, 1928 and Lisposoma josehermana Lamoral, 1979, based on recent fieldwork in Namibia
Redescription of Heterometrus latimanus and confirmation of the genus Heterometrus (Scorpiones: Scorpionidae) in Pakistan by H. Muhammad Tahir( )

3 editions published in 2014 in English and held by 18 WorldCat member libraries worldwide

Scorpions of the genus Heterometrus Ehrenberg, 1828, are distributed from India and Sri Lanka throughout the Southeast Asian mainland and archipelagos as far as Wallace's Line. Despite this widespread distribution, Heterometrus was not recorded from Pakistan until a single specimen from Azad Kashmir was reported from the collection of the Pakistan Museum of Natural History, Islamabad. Perhaps because the specimen was misidentified as Heterometrus wroughtoni (Pocock, 1899), a species that occurs much farther to the southeast in India, the presence of Heterometrus in Pakistan remained uncertain until fresh material of a distinctive species of Heterometrus was recently collected at several locations in Khyber Pakhtoon Khawa. After comparison of the material with the holotype and only known specimen of a little-known species, Heterometrus latimanus (Pocock, 1894), with an indefinite type locality in "India," the Pakistani material was determined to be conspecific. In the present contribution, H. latimanus is redescribed based on adult males and females from several localities, and the specimen from Azad Kashmir tentatively assigned to it, confirming the presence of Heterometrus in Pakistan. The new locality records extend the distribution of the genus considerably to the northwest, and west of the Indus River for the first time. The known records of H. latimanus appear to be isolated from other Heterometrus occurring on the Indian subcontinent by the Great Indian (Thar) Desert, an arid, sandy basin extending from eastern Pakistan to northwestern India
Cryptic diversity of South African trapdoor spiders : three new species of Stasimopus Simon, 1892 (Mygalomorphae, Ctenizidae), and redescription of Stasimopus robertsi Hewitt, 1910 by Ian Engelbrecht( )

2 editions published in 2012 in English and held by 17 WorldCat member libraries worldwide

Three new species of Stasimopus Simon, 1892, are described from the Gauteng and North West provinces of South Africa. They are readily distinguished from all other known Stasimopus species by the presence of spinules in the tarsal scopulae on the first two pairs of legs of adult males. The only described species recorded in the vicinity, Stasimopus robertsi Hewitt, 1910, which appears to be endemic to northern Gauteng Province, is redescribed. The four species are comprehensively illustrated, a key to identify the adult males from those of other new species in the region is provided, and their conservation status discussed. Available evidence suggests that many Stasimopus species remain to be discovered and described, but significant effort will be required to obtain adult males, considered important for accurate species delimitation in the genus
A new species of Urodacus (Scorpiones, Urodacidae) from Western Australia by Erich S Volschenk( )

2 editions published in 2012 in English and held by 17 WorldCat member libraries worldwide

A new urodacid scorpion, Urodacus butleri, n. sp., is described from Barrow Island and the Pilbara bioregion of Western Australia. This species is unusually dark in color; it is compared and contrasted with three morphologically similar species, Urodacus manicatus (Thorell, 1876), Urodacus novaehollandiae Peters, 1861, and Urodacus planimanus Pocock, 1893
Myrmecicultoridae, a new family of myrmecophilic spiders from the Chihuahuan Desert (Araneae, Entelegynae) by Martín J Ramírez( )

2 editions published in 2019 in English and held by 17 WorldCat member libraries worldwide

The new genus and species Myrmecicultor chihuahuensis Ramírez, Grismado, and Ubick is described and proposed as the type of the new family, Myrmecicultoridae Ramírez, Grismado, and Ubick. The species is ecribellate, with entelegyne genitalia, two tarsal claws, without claw tufts, and the males have a retrolateral palpal tibial apophysis. Some morphological characters suggest a possible relationship with Zodariidae or Prodidomidae, but the phylogenetic analysis of six markers from the mitochondrial (12S rDNA, 16S rDNA, cytochrome oxidase subunit I) and nuclear (histone H3, 18S rDNA, 28S rDNA) genomes indicate that M. chihuahuensis is a separate lineage emerging near the base of the Dionycha and the Oval Calamistrum clade. The same result is obtained when the molecular data are combined with a dataset of morphological characters. Specimens of M. chihuahuensis were found associated with three species of harvester ants, Pogonomyrmex rugosus, Novomessor albisetosis, and Novomessor cockerelli, and were collected in pitfall traps when the ants are most active. The known distribution spans the Big Bend region of Texas (Presidio, Brewster, and Hudspeth counties), to Coahuila (Cuatro Ciénegas) and Aguascalientes (Tepezalá), Mexico
Systematic revision of the neotropical scorpion genus Chactopsis Kraepelin, 1912 (Chactoidea, Chactidae), with descriptions of two new genera and four new species by J. A Ochoa( Book )

2 editions published in 2013 in English and held by 16 WorldCat member libraries worldwide

The Neotropical chactid scorpion genus Chactopsis Kraepelin, 1912, is revised. New diagnoses are presented for all previously described species, most of which have not been revised since their original description. The trichobothrial pattern is reinterpreted and the hemispermatophore described for the first time. Chactopsis is restricted to eight species, two of which are new: Chactopsis chullachaqui, n. sp., from Peru and Chactopsis curupira, n. sp., from Brazil. Chactopsis insignis Kraepelin, 1912, is redescribed and supplementary data on pedipalp trichobothria and hemispermatophore (where known) provided for Chactopsis amazonica Lourenço and Francke, 1986, Chactopsis barajuri González-Sponga, 1982, Chactopsis buhrnheimi Lourenço, 2003, Chactopsis siapaensis González-Sponga, 1991, and Chactopsis sujirima González-Sponga, 1982. Two new genera are created to accommodate the remaining species, formerly assigned to Chactopsis, based on a cladistic analysis of morphological characters. Chactopsoides, n. gen., accommodates Chactopsoides anduzei (González-Sponga, 1982), n. comb. (type species), and Chactopsoides marahuacaensis (González-Sponga, 2004), n. comb., Chactopsoides gonzalezspongai, n. sp., from Venezuela, and Chactopsoides yanomami (Lourenço et al., 2011), n. comb., from Brazil. Chactopsoides anduzei, n. comb., is redescribed and Chactopsis carolinae Botero-Trujillo, 2008, synonymized with it. Supplementary data on pedipalp trichobothria are provided for C. marahuacaensis, n. comb. Megachactops, n. gen., accommodates Megachactops coriaceo (González-Sponga, 1991), n. comb., and Megachactops kuemoi, n. sp. (type species), from Venezuela. Supplementary data on pedipalp trichobothria and hemispermatophore are provided for M. coriaceo, n. comb. A key to identification of the species of Chactopsis, Chactopsoides, n. gen., and Megachactops, n. gen., is provided, their morphology illustrated, and distribution records mapped

Cheliceral morphology in Solifugae (Arachnida) : primary homology, terminology, and character survey by Tharina Bird( Book )

3 editions published in 2015 in English and held by 15 WorldCat member libraries worldwide

Arachnids of the order Solifugae (solifuges, false spiders, sun spiders, camel spiders, Walzenspinne, wind spiders) possess the largest jaws for body size among the Chelicerata. The chelicerae provide the most important character systems for solifuge systematics, including dentition and the male cheliceral flagellum, both used extensively for species delimitation and diagnosis. However, the terminology used for cheliceral characters is not standardized and often contradictory, in part because it fails to represent homologous structures among taxa. Misinterpretation of character homology may introduce errors in phylogenetic analyses concerning relationships within Solifugae and among the orders of Chelicerata. This contribution presents the first comprehensive analysis of cheliceral morphology across the order Solifugae, the aims of which were to provide a broad survey of cheliceral characters for solifuge systematics, to identify and reinterpret structures based on primary homology, to revise the terminology to be consistent with homology hypotheses, and to provide a guide to terminological synonyms and character interpretations in the literature. Chelicerae were studied in 188 exemplar species (17% of the total), representing all 12 solifuge families, 17 of the 19 subfamilies, 64 genera (46% of the total), and the full range of variation in cheliceral morphology across the order. In total, 157 species representing 49 genera and 17 subfamilies are illustrated. Hypotheses of character transformation, particularly concerning the male flagellum, and a standardized terminology, are presented. The functional morphology of the chelicerae is discussed and the role of sexually dimorphic modifications to the male chelicerae in mating behavior emphasized. The revised terminology, based on hypotheses of primary homology, will facilitate solifuge revisionary systematics and provide a stronger basis for reconstructing phylogenetic relationships within the order Solifugae and testing the phylogenetic position of the order within Chelicerata
Systematics of the short-tailed whipscorpion genus Stenochrus Chamberlin, 1922 (Schizomida, Hubbardiidae), with descriptions of six new genera and five new species by Rodrigo Monjaraz-Ruedas( Book )

4 editions published in 2019 in English and held by 13 WorldCat member libraries worldwide

The short-tailed whipscorpion genus, Stenochrus Chamberlin, 1922 (Schizomida: Hubbardiidae Cook, 1899), occurring in North and Central America, is redefined and revised based on simultaneous phylogenetic analysis of 61 morphological characters and 2968 aligned DNA nucleotides from two markers in the nuclear genome, the internal transcribed spacer (ITS) and 28S rDNA, and two markers in the mitochondrial genome, cytochome c oxidase subunit I (COI) and 12S rDNA, for a comprehensive taxon sample. Six new genera are described: Ambulantactus, gen. nov.; Baalrog, gen. nov.; Harveyus, gen. nov.; Nahual, gen. nov.; Schizophyxia, gen. nov.; Troglostenochrus, gen. nov. Heteroschizomus Rowland, 1973, stat. rev., is revalidated and its type species, Heteroschizomus goodnightorum Rowland, 1973, reinstated. Six new species are described: Ambulantactus aquismon, sp. nov.; Ambulantactus montielae, sp. nov.; Baalrog yacato, sp. nov.; Harveyus contrerasi, sp. nov.; Heteroschizomus kekchi, sp. nov.; Nahual bokmai, sp. nov. Eighteen new combinations are created by transferring species, previously accommodated in Stenochrus, to other genera: Ambulantactus davisi (Gertsch, 1940), comb. nov.; Baalrog magico (Monjaraz-Ruedas and Francke, 2018), comb. nov.; Baalrog sbordonii (Brignoli, 1973), comb. nov.; Harveyus mexicanus (Rowland, 1971a), comb. nov.; Harveyus mulaiki (Gertsch, 1940), comb. nov.; Harveyus reddelli (Rowland, 1971a), comb. nov.; Heteroschizomus meambar (Armas and Víquez, 2010), comb. nov.; Heteroschizomus orthoplax (Rowland, 1973a), comb. nov.; Heteroschizomus silvino (Rowland and Reddell, 1977), comb. nov.; Nahual caballero (Monjaraz-Ruedas and Francke, 2018), comb. nov.; Nahual lanceolatus (Rowland, 1975), comb. nov.; Nahual pallidus (Rowland, 1975), comb. nov.; Pacal moisii (Rowland, 1973), comb. nov.; Pacal tepezcuintle (Armas and Cruz-López, 2009), comb. nov.; Schizophyxia bartolo (Rowland, 1973), comb. nov.; Schizophyxia lukensi (Rowland, 1973), comb. nov.; Troglostenochrus palaciosi (Reddell and Cokendolpher, 1986), comb. nov.; Troglostenochrus valdezi (Monjaraz-Ruedas, 2012), comb. nov. The male of B. sbordonii is determined to be heterospecific with the holotype female and described as B. yacato. The females of H. goodnightorum and N. lanceolatus are described for the first time. Following these revisions, seven species remain within Stenochrus: Stenochrus alcalai Monjaraz-Ruedas and Francke, 2018; Stenochrus chimalapas Monjaraz-Ruedas and Francke, 2018; Stenochrus gruta Monjaraz-Ruedas and Francke, 2018; Stenochrus guatemalensis (Chamberlin, 1922); Stenochrus leon Armas, 1995; Stenochrus pecki (Rowland, 1973); Stenochrus portoricensis Chamberlin, 1922. Olmecazomus, nom. nov., is proposed as a replacement name for the junior homonym, Olmeca Monjaraz-Ruedas and Francke, 2017, creating three new combinations: Olmecazomus brujo (Monjaraz-Ruedas and Francke, 2017), comb. nov.; Olmecazomus cruzlopezi (Monjaraz-Ruedas and Francke, 2017), comb. nov.; Olmecazomus santibanezi (Monjaraz-Ruedas and Francke, 2017), comb. nov. A key to identification of the hubbardiid genera of North America is provided and the utility of various character systems for the diagnosis of schizomid genera discussed. The integration of morphological and molecular data not only increased knowledge of the schizomid diversity in the New World but disentangled what was once considered a homoplastic and variable morphology in a large "catch-all" genus into discrete units each diagnosable by unique character combinations
Systematic revision of the North American syntropine vaejovid scorpion genera Maaykuyak, Syntropis, and Vizcaino, with description of the adults of Syntropis williamsi by Edmundo González-Santillán( Book )

3 editions published in 2016 in English and held by 12 WorldCat member libraries worldwide

Four distinct genera, forming two monophyletic groups, are basal in the phylogeny of the North American vaejovid scorpion subfamily Syntropinae Kraepelin, 1905: Konetontli González-Santillán and Prendini, 2013; Maaykuyak González-Santillán and Prendini, 2013; Syntropis Kraepelin, 1900; and Vizcaino González-Santillán and Prendini, 2013. All except the species of Konetontli, treated elsewhere, are revised in the present contribution. The two species of Maaykuyak, three species of Syntropis, and monotypic Vizcaino are redescribed; the adults of Syntropis williamsi Soleglad et al., 2007, described for the first time; keys to identification of the species of Maaykuyak and Syntropis presented; and new locality records and updated distribution maps provided for all species covered
Systematic revision of the North American syntropine vaejovid scorpions with a subaculear tubercle, Konetontli González-Santillán and Prendini, 2013 by Edmundo González-Santillán( Book )

2 editions published in 2015 in English and held by 11 WorldCat member libraries worldwide

The Mexican vaejovid scorpion genus Konentontli González-Santillán and Prendini, 2013, was created to accommodate five species united, among other characters, by a subaculear tubercle on the telson. Species of Konetontli are among the smallest vaejovid scorpions. Their very small size, cryptic coloration, and apparently seasonal surface activity may explain their rarity in collections and it is likely that more undescribed species await discovery. In the present contribution, we describe four new species (Konetontli ignes, sp. nov.; Konetontli ilitchi, sp. nov.; Konetontli juxtlahuaca, sp. nov.; Konetontli migrus, sp. nov.) and revalidate Konetontli zihuatanejensis (Baldazo-Monsivaiz, 2003), comb. nov., previously synonymized with Konetontli acapulco (Armas and Martín-Frías, 2001), raising to 10 the number of species in the genus; redescribe previously described species, including the first description of the female of Konetontli nayarit (Armas and Martín-Frías, 2001); and present new records, comprehensive distribution maps, and a key to the identification of the species
Systematic revision of the neotropical club-tailed scorpions, Physoctonus, Rhopalurus, and Troglorhopalurus, revalidation of Heteroctenus, and descriptions of two new genera and three new species (Buthidae, Rhopalurusinae) by Lauren A Esposito( Book )

3 editions published in 2017 in English and held by 11 WorldCat member libraries worldwide

The Neotropical "club-tailed" scorpions of the genus Rhopalurus Thorell, 1876, and two related genera in family Buthidae C.L. Koch, 1837, i.e., Physoctonus Mello-Leitão, 1934, and Troglorhopalurus Lourenço et al., 2004, are revised, based on a simultaneous phylogenetic analysis of 90 morphological characters and 4260 aligned DNA nucleotides from three mitochondrial and two nuclear gene loci. The monophyletic New World buthid subfamily Rhopalurusinae Bucherl, 1971, to which these scorpions were originally assigned, is redefined, revised diagnoses and a key to identification of its genera and species (except for Centruroides Marx, 1890) provided, and their distributions mapped. The paraphyly of Rhopalurus Thorell, 1876, which comprises several monophyletic groups congruent with its disjunct distribution, justifies its relimitation and that of Troglorhopalurus Lourenço et al., 2004, the revalidation of Heteroctenus Pocock, 1893, and creation of Ischnotelson, gen. nov. (type species: Rhopalurus guanambiensis Lenarducci, Pinto-da-Rocha and Lucas, 2005) and Jaguajir, gen. nov. (type species: Rhopalurus agamemnon C.L. Koch, 1839). Ten new combinations are proposed: Heteroctenus abudi (Armas and Marcano Fondeur, 1987), comb. nov.; Heteroctenus bonettii (Armas, 1999), comb. nov.; Heteroctenus garridoi (Armas, 1974), comb. nov.; Heteroctenus gibarae (Teruel, 2006), comb. nov.; Heteroctenus princeps (Karsch, 1879), comb. nov.; Ischnotelson guanambiensis (Lenarducci, Pinto-da-Rocha and Lucas, 2005), comb. nov.; Jaguajir agamemnon (C.L. Koch, 1839), comb. nov.; Jaguajir pintoi (Mello-Leitão, 1932), comb. nov.; Jaguajir rochae (Borelli, 1910), comb. nov.; Troglorhopalurus lacrau (Lourenço and Pinto-da-Rocha, 1997), comb. nov. Three new species are described: Ischnotelson peruassu, sp. nov. (type locality: Parque Estadual do Peruassu, Minas Gerias, Brazil); Physoctonus striatus, sp. nov. (type locality: Castelo do Piauí, Piauí, Brazil); Rhopalurus ochoai, sp. nov. (type locality: San Agustín, Edo. Zulia, Venezuela). Fifteen new junior subjective synonyms are proposed: Rhopalurus acromelas Lutz and Mello, 1922, Rhopalurus melleipalpus Lutz and Mello, 1922, Rhopalurus iglesiasi Werner, 1927, Rhopalurus lambdophorus Mello-Leitão, 1932, Rhopalurus dorsomaculatus Prado, 1938, and Rhopalurus goiasensis Prado, 1940 = Jaguajir agamemnon (C.L. Koch, 1839); Rhopalurus pintoi kourouensis Lourenço, 2008 = Jaguajir pintoi (Mello-Leitão, 1932); Rhopalurus crassicauda Caporiacco, 1947, Rhopalurus amazonicus Lourenço, 1986, and Rhopalurus crassicauda paruensis Lourenço, 2008 = Rhopalurus laticauda Thorell, 1876; Rhopalurus melloleitaoi Teruel and Armas, 2006, and Rhopalurus aridicola (Teruel and Armas, 2012) = Heteroctenus junceus (Herbst, 1800); Rhopalurus granulimanus Teruel, 2006 = Heteroctenus gibarae (Teruel, 2006); Rhopalurus virkii Santiago-Blay, 2009 = Heteroctenus abudi (Armas and Marcano Fondeur, 1987); Rhopalurus brejo Lourenço, 2014 = Troglorhopalurus lacrau (Lourenço and Pinto-da-Rocha, 1997)
Redefinition and systematic revision of the East African scorpion genus Pandinoides (Scorpiones, Scorpionidae) with critique of the taxonomy of Pandinus, sensu lato by Lorenzo Prendini( Book )

The scorpion fauna of East Africa, encompassing Burundi, Kenya, Tanzania, Rwanda, and Uganda, is more diverse than those of West and Central Africa, but a systematic survey has never been conducted and the distributions of its species remain poorly understood. A recent opportunity to examine two extensive collections of East African, and predominantly Kenyan, scorpions and new material acquired by the author permitted a reassessment of the fauna of the region. The present contribution, the first of several emanating from this research, comprises two parts. The first part presents a redefinition and revision of the scorpionid genus Pandinoides Fet, 1997, with a redescription of the type species, Pandinoides cavimanus (Pocock, 1888), a revalidation and redescription of Pandinoides militaris (Pocock, 1900), and a description of Pandinoides duffmackayi, sp. nov. Pending reassessment of the genera and subgenera of Pandinus, sensu lato, based on quantitative phylogenetic analysis, Pandinoides is restricted to the three species with a marked concave depression in the retrodorsal surface of the pedipalp chela manus of the adult male, and Pandinus platycheles Werner, 1916, transferred to Pandinus subgenus Pandinoriens Rossi, 2015, creating a new combination: Pandinus (Pandinoriens) platycheles (Werner, 1916), comb. nov. The availability of large series comprising both sexes and all stages of the three Pandinoides species covered herein revealed considerable variation in counts of pedipalp trichobothria, spiniform macrosetae of the leg telotarsi, and pectinal teeth, among and even within individual conspecifics, calling into question the widespread practice of defining species and supraspecific taxa almost exclusively on trivial meristic differences between small samples of material (often singletons, female or immature). Furthermore, whereas neobothriotaxic patterns with low counts may provide appropriate diagnostic characters for genera and species, in combination with other characters, this is generally inadvisable when trichobothrial counts are high, due to the greater instability of the patterns. The second part of this contribution assesses the validity of several putative species of Pandinus, sensu lato, recently described or revalidated, in light of data presented in the first part, and presents 10 new synonyms: Heterometrus roeseli Simon, 1872 = Pandinus (P.) imperator (C.L. Koch, 1841), syn. nov.; Pandinus (P.) camerounensis Lourenço, 2014 = Pandinus (P.) imperator (C.L. Koch, 1841), syn. nov.; Pandinurus (P.) prendinii Rossi, 2015 = Pandinurus (P.) sudanicus (Hirst, 1911), syn. nov.; Pandinurus (Pandicaporiaccous) Rossi, 2015 = Pandinurus (Pandiborellius) Rossi, 2015, syn. nov.; Pandinurus (Pandicaporiaccous) janae Rossi, 2015 = Pandinurus (Pandiborellius) percivali (Pocock, 1902), syn. nov.; Pandinurus (Pandipalpus) bartolozii Rossi, 2015 = Pandinurus (Pandipalpus) viatoris (Pocock, 1890), syn. nov.; Pandinurus (Pandipalpus) flagellicauda Rossi, 2015 = Pandinurus (Pandipalpus) viatoris (Pocock, 1890), syn. nov.; Pandinurus (Pandipalpus) lorenzoi Rossi, 2015 = Pandinurus (Pandipalpus) viatoris (Pocock, 1890), syn. nov.; Pandinurus (Pandipalpus) pantinii Rossi, 2015 = Pandinurus (Pandipalpus) viatoris (Pocock, 1890), syn. nov.; Pandinurus (Pandipalpus) pygmaeus Rossi, 2015 = Pandinurus (Pandipalpus) viatoris (Pocock, 1890), syn. nov

The North American vinegaroon, Mastigoproctus giganteus (Lucas, 1835), is demonstrated to comprise a complex of range-restricted species rather than a single widespread polymorphic species. Seven species are recognized based on morphological characters of the adult males, including the arrangement of spines on the prodorsal margin of the pedipalp trochanter, the position of the epistoma on the carapace, the presence of a stridulatory organ on opposing surfaces of the chelicerae and the pedipalp coxa, the presence of a patch of setae on sternite V, and the shape and macrosculpture of the retrolateral surface of the pedipalp femur. The two currently recognized subspecies are elevated to species: Mastigoproctus mexicanus (Butler, 1872), stat. nov., and Mastigoproctus scabrosus (Pocock, 1902), stat. nov. Mastigoproctus floridanus (Lönnberg, 1897) is revalidated from synonymy with M. giganteus. Redescriptions of M. giganteus and the other three species, based on both sexes, are provided, and three new species described: Mastigoproctus cinteotl, sp. nov., from Tamaulipas, Mexico; Mastigoproctus tohono, sp. nov., from Arizona and Sonora, Mexico; Mastigoproctus vandevenderi, sp. nov., from Sonora, Mexico. The present contribution raises the diversity of the Order Thelyphonida Latreille, 1804, in North America from one species to seven. Three species occur in the United States (one each in Arizona, Texas, and Florida), six species occur in Mexico, and two species occur in both countries
