A New Species Of The Genus Oiclus Simon, 1880 (Scorpiones: Scorpionidae: Diplocentrinae) From Guadeloupe, Lesser Antilles, Rolando Teruel, Léonard Chazal

Euscorpius

A new species of Oiclus Simon, 1880 is described from Guadeloupe in Lesser Antilles. It is closely related to Oiclus purvesii s. s. (Becker, 1880), and represents the first record of this genus from mainland Guadeloupe. The previous record of O. purvesii s. s. from Terre-de-Haut (Les Saintes, a small islet offshore Basse-Terre) is regarded as dubious, as it possibly refers to the new taxon herein described. Also, some topics on the taxonomy and distribution of this genus are briefly discussed.

New Picobuthoid Scorpions (Scorpiones: Buthidae) From Oman, Graeme Lowe

Euscorpius

Five new species of diminutive buthid scorpions are described from Oman. Two belong to Microbuthus Kraepelin, 1898, a genus with heavily sclerotized, smooth, strongly pitted posterior metasomal segments, abbreviated telson, and pedipalps with 9 femoral and 6–7 external patellar trichobothria: M. gardneri, sp. nov., from the Al Hajar Mountains, and M. kristensenorum, sp. nov., from the Dhofar Mountains and Hadhramaut of Yemen, which was long misidentified as M. pusillus Kraepelin, 1898. Two additional new species are placed in a new genus Picobuthus, gen. nov., differentiated by granular posterior metasomal segments, elongate telson, pedipalps with …

Scorpions Of Iran (Arachnida, Scorpiones). Part V. Chahar Mahal & Bakhtiyari Province, Khodadad Pirali-Kheirabadi, Shahrokh Navidpour, Victor Fet, František Kovařík, Michael E. Soleglad

Euscorpius

Ten species of scorpions belonging to three families are reported from the montane Chahar Mahal & Bakhtiyari Province of Iran. Of these, only Razianus zarudnyi (Birula, 1903) was formerly reported for this province, while nine species are reported for the first time: Androctonus crassicauda (Olivier, 1807), Compsobuthus matthiesseni (Birula, 1905), Hottentotta saulcyi (Simon, 1880), Hottentotta zagrosensis Kovařík, 1997, Mesobuthus eupeus phillipsii (Pocock, 1889), Odontobuthus doriae (Thorell, 1876), Orthochirus zagrosensis Kovařík, 2004, Hemi- scorpius lepturus Peters, 1861, and Scorpio maurus townsendi (Pocock, 1900). Also presented is a key to all species of scorpions found in the Chahar Mahal & Bakhtiyari Province.

Tityus Ythieri Lourenço, 2007 Is A Synonym Of Tityus Magnimanus Pocock, 1897 (Scorpiones: Buthidae): A Combined Approach Using Morphology, Hybridization Experiments, Chromosomes, And Mitochondrial Dna, František Kovařík, František Šťáhlavský, Tereza Kořínková, Jiří Král, Tom Van Der Ende

Euscorpius

Diagnostic morphological differences to distinguish between two scorpion species, Tityus ythieri Lourenço, 2007 and T. magnimanus Pocock, 1897 do not exist; moreover, the two easily hybridize to produce fertile offspring. Therefore, we suggest that T. ythieri is a synonym of T. magnimanus. This conclusion is further supported by (1) very similar distribution of relative sizes of chromosome bivalents in both species, (2) regular pairing of homologous chromosomes in meiosis of their hybrids, and (3) identical sequences of mitochondrial DNA (COI) markers.

Distribution Of Hottentotta Saulcyi (Simon, 1880) (Scorpiones: Buthidae) In Turkey, Ersen Aydın Yağmur, Halil Koç, Mehmet Yalçın

Euscorpius

Distribution of Hottentotta saulcyi (Simon, 1880) (Scorpiones: Buthidae) in Turkey is investigated, and new distributional records are given. Formerly, this species was known only from Mardin Province; here, it is recorded for the first time from Batman, Şırnak, and Hakkâri Provinces.

The True Identity Of Scorpio (Atreus) Obscurus Gervais, 1843 (Scorpiones, Buthidae), Wilson R. Lourenço, Elise-Anne Leguin

Euscorpius

The true identity of the scorpion Scorpio (Atreus) obscurus Gervais, 1843 is discussed based on new data. The original type material was recently discovered in the collections of the Muséum national d’Histoire naturelle in Paris, which confirms that this old species, originally described by Gervais based on two female specimens from French Guiana, does indeed belong to the genus Tityus C. L. Koch, 1836. Furthermore, an analysis of all morphological characteristics of Tityus (Atreus) obscurus verifies its position as a senior synonym of both Tityus paraensis Kraepelin, 1896 and Tityus cambridgei Pocock, 1897. In this paper, we designate the two …

Scorpions Of Iran (Arachnida, Scorpiones). Part Iv. Kohgilouyeh & Boyer Ahmad Province, Shahrokh Navidpour, František Kovařík, Michael E. Soleglad, Victor Fet

According to previous surveys, only Mesobuthus eupeus phillipsii (Pocock, 1889), Orthochirus zagrosensis Kovařík, 2004, and Hemiscorpius lepturus Peters, 1861 have been recorded from Kohgilouyeh & Boyer Ahmad Province. Collections made by a team under Shahrokh Navidpour (Razi Reference Laboratory of Scorpion Research, Razi Vaccine and Serum Research Institute, Ahvaz, Khoozestan, Iran) reveal eight other species belonging to two families recorded from the province for the first time: Androctonus crassicauda (Olivier, 1807); Compsobuthus matthiesseni (Birula, 1905); Hottentotta saulcyi (Simon, 1880); Hottentotta zagrosensis Kovařík, 1997; Odontobuthus bidentatus Lourenço et Pézier, 2002; Orthochirus iranus Kovařík, 2004; Razianus zarudnyi (Birula, 1903); and Scorpio maurus …

The Geographic Pattern Of Distribution Of The Genus Rhopalurus Thorell, 1876 In The Guayana-Amazon Region (Scorpiones: Buthidae), Wilson R. Lourenço

Euscorpius

A new discussion is proposed on the geographic patterns of distribution presented by the species of the genus Rhopalurus Thorell, inhabiting the savannah formations of the northern South America. Two lineages of Rhopalurus species are defined for this region, each one containing forms with very weak morphological differences, a consequence of only a minor process of differentiation. The observed pattern of distribution and differentiation is suggested to be directly associated with more or less recent palaeoclimatic vicissitudes, which took place in tropical South America during Pleistocene. Two new subspecies are also described, representing new records of Rhopalurus for Brazil and …

Etudes On Iurids, Iii. Revision Of The Genus Iurus Thorell, 1876 (Scorpiones: Iuridae), With A Description Of Two New Species From Turkey, František Kovařík, Victor Fet, Michael E. Soleglad, Ersen Aydın Yağmur

Euscorpius

This revision is based on a comprehensive analysis of largely new, very extensive material encompassing 341 specimens (58 from Greece and 283 from Turkey). The type species Iurus dufoureius (Brullé, 1832) is restricted to Greece. Iurus asiaticus Birula, 1903 is confirmed as a distinct species, limited to eastern Anatolia. Most widespread in southern Turkey is another species, Iurus kraepelini von Ubisch, 1922, which is here restored from synonymy. We also describe two new species from Turkey: Iurus kadleci, sp. nov. from Antalya and Mersin Provinces (sympatric with I. kraepelini), and Iurus kinzelbachi, sp. nov. from İzmir and …

This new taxon shares several unusual features with Ananteris tolimana Teruel et García, 2007, from the Andean region of Tolima Department. With this addition, the number of Colombian species of Ananteris is raised to seven.

Contributions To Scorpion Systematics. Iii. Subfamilies Smeringurinae And Syntropinae (Scorpiones: Vaejovidae), Michael E. Soleglad, Victor Fet

Euscorpius

Stockwell (1989), in an unpublished revision, suggested splitting the family Vaejovidae in two subfamilies, introducing also four tribes and four new genera. These results have not been reevaluated for 20 years. Here, we establish a new subfamily Smeringurinae, subfam. nov., with two tribes, four genera, and 40 species and subspecies. The subfamily Smeringurinae includes two tribes: Smeringurini, trib. nov. and Paravaejovini, trib. nov. The tribe Smeringurini includes three genera: Paruroctonus Werner, 1934; Smeringurus Haradon, 1983; and Vejovoidus Stahnke, 1974. The tribe Paravaejovini includes the genus Paravaejovis Williams, 1980. We restore from synonymy the subfamily Syntropinae Kraepelin, 1905, and …

A New Species Of Odontobuthus (Scorpiones: Buthidae) From Northern Oman, Graeme Lowe

Euscorpius

The Asian buthid genus Odontobuthus is newly recorded from the Arabian Peninsula where is represented by O. brevidigitus sp. nov. from the Batínah coast and foothills of the Al Hajar mountains of northern Oman. The new species is characterized by short pedipalp fingers, long pectines with narrow basal middle lamella, 2–3 enlarged denticles on ventrosubmedian carinae of metasoma II–III, stout metasoma IV with 10 anterior transverse granules, 3 lateral anal lobes, and enlarged dentition on the ventral anal arch. A model is proposed for the speciation of Odontobuthus by westward dispersal of an ancestral population on the Indus floodplain, …
