Serrula In Retrospect: A Historical Look At Scorpion Literature (Scorpiones: Orthosterni), Matthew R. Graham, Victor Fet
Serrula In Retrospect: A Historical Look At Scorpion Literature (Scorpiones: Orthosterni), Matthew R. Graham, Victor Fet
Euscorpius
Serrula, a small comb-like structure on the ventral aspect of cheliceral movable finger in scorpions, has often been overlooked or ignored. Scorpion genera that are currently known to possess serrula belong to six families: Chactidae, Euscorpiidae, Iuridae, Pseudochactidae, Superstitioniidae, and Vaejovidae. All relevant literature on scorpion serrula is reviewed, and serrula of representative scorpion taxa is illustrated by SEM images. We suggest that the inconsistency in reporting serrula is based on several factors (or combination thereof): (a) serrula tines can quite often be broken off partially or completely, especially in adults; (b) serrula can be vestigial and hardly visible under …
Taxonomic Position Of The Genus Sassanidotus Farzanpay, 1987 (Scorpiones: Buthidae), František Kovařík, Victor Fet
Taxonomic Position Of The Genus Sassanidotus Farzanpay, 1987 (Scorpiones: Buthidae), František Kovařík, Victor Fet
Euscorpius
Sassanidotus Farzanpay, 1987 is a valid genus closely related to Compsobuthus Vachon, 1949, with which it shares most characters including the shape of carinae on the carapace and mesosoma. The main difference is that Sassanidotus has only three granules located proximally to the terminal granule on the movable finger of pedipalp, whereas Compsobuthus and also Mesobuthus Vachon, 1950 have four such granules. Sassanidotus Farzanpay, 1987 includes two species, Sassanidotus zarudnyi (Birula, 1900) (type species) from Iran and Sassanidotus gracilis thus zarudnyi sarghadensis Birula, 1903, syn. n.) from Afghanistan, Iran, and Pakistan. The neotype is designated for S. zarudnyi.
Redescription And Lectotype Designation Of Vaejovis Lapidicola Stahnke, 1940 (Scorpiones: Vaejovidae), Matthew R. Graham
Redescription And Lectotype Designation Of Vaejovis Lapidicola Stahnke, 1940 (Scorpiones: Vaejovidae), Matthew R. Graham
Euscorpius
The original description of the Arizona scorpion species Vaejovis lapidicola Stahnke, 1940 consists of a single paragraph. Furthermore, a holotype for this species was never designated. To remedy this, two syntypes of V. lapidicola were obtained for study. A male syntype is redescribed and designated the lectotype, and a female is assigned as a paralectotype. The taxonomic status of V. lapidicola is also confirmed.
The Effect Of Insularity On The Seasonal Population Structure Of Mesobuthus Gibbosus (Scorpiones: Buthidae), Dimitris Kaltsas, Iasmi Stathi, Moysis Mylonas
The Effect Of Insularity On The Seasonal Population Structure Of Mesobuthus Gibbosus (Scorpiones: Buthidae), Dimitris Kaltsas, Iasmi Stathi, Moysis Mylonas
Euscorpius
We compared the population structure of Mesobuthus gibbosus from autumn to mid-summer at two similar phryganic ecosystems, one in continental Greece (Thessalia, near Volos city) and one in insular Greece (eastern Crete). Data were collected monthly using the capture-recapture method. At both sites, density was low during the cold period and increased towards summer. During the samplings, only a small percentage of each population was present. Population density and co-occurrence of scorpions with scorpions or other animals was higher in Crete than in Volos, probably due to the higher inter- and intraspecific competition in Volos. The population structure of the …
Duplication Of Pedipalp Segments In The Scorpion Androctonus Crassicauda (Olivier, 1807), Ayşegül Karataş, Mustafa Kürtüllü
Duplication Of Pedipalp Segments In The Scorpion Androctonus Crassicauda (Olivier, 1807), Ayşegül Karataş, Mustafa Kürtüllü
Euscorpius
An unusual duplication of pedipalp segments is reported from the buthid scorpion Androctonus crassicauda. While the right pedipalp is normal, the anomaly described here occurred on the left pedipalp. This abnormally developed pedipalp included nine segments instead of normal six. It has two trochanters, two femurs and two patellae; the segments are arranged in the following order: coxa, trochanter I, femur I, patella I, trochanter II, femur II, patella II, chela hand, and movable finger. Morphometric measurements, photographs, and general features of the specimen are given.
Constellation Array In Scorpion Genera Paruroctonus, Smeringurus, Vejovoidus, And Paravaejovis (Scorpiones: Vaejovidae), Victor Fet, Michael E. Soleglad, Michael Brewer, David P. A. Neff, Michael L. Norton
Constellation Array In Scorpion Genera Paruroctonus, Smeringurus, Vejovoidus, And Paravaejovis (Scorpiones: Vaejovidae), Victor Fet, Michael E. Soleglad, Michael Brewer, David P. A. Neff, Michael L. Norton
Euscorpius
The constellation array (a recently discovered sensory structure on the fixed finger of pedipalp; Fet et al., 2006) is analyzed for a large set of species belonging to four genera in the family Vaejovidae: Paruroctonus, Smeringurus, Vejovoidus, and Paravaejovis. It is shown that this structure is an important taxonomic character. Two distinct configurations are identified, a two-sensilla array for Paruroctonus + Smeringurus + Vejovoidus and a three-sensilla array for genus Paravejovis, both differing from other vaejovid configurations so far investigated. The topology of these two array configurations are analyzed using landmark setae identified in this study.

Contributions To Scorpion Systematics. Ii. Stahnkeini, A New Tribe In Scorpion Family Vaejovidae (Scorpiones: Chactoidea), Michael E. Soleglad, Victor Fet
Euscorpius
The diagnostic characters originally established by Herbert L. Stahnke (1940a, 1940b, 1974) in his description of genus Serradigitus are studied in detail from several new perspectives. A new genus, Stahnkeus, gen. nov., is described based on the presence of inner accessory (IAD) denticles on the chelal fingers, unprecedented in family Vaejovidae. Five species of Serradigitus are transferred to Stahnkeus: Stahnkeus harbisoni (Williams, 1970), comb. nov. (=Serradigitus harbisoni); Stahnkeus deserticola (Williams, 1970), comb. nov. (=Serradigitus deserticola); Stahnkeus subtilimanus (Soleglad, 1972), comb. nov. (=Serradigitus subtilimanus); Stahnkeus allredi (Sissom et Stockwell, 1991), …
The Systematic Position Of The Scorpion Genera Heteroscorpion Birula, 1903 And Urodacus Peters, 1861 (Scorpiones: Scorpionoidea), Michael E. Soleglad, Victor Fet, František Kovařík
The Systematic Position Of The Scorpion Genera Heteroscorpion Birula, 1903 And Urodacus Peters, 1861 (Scorpiones: Scorpionoidea), Michael E. Soleglad, Victor Fet, František Kovařík
Euscorpius
Stockwell (1989), in an unpublished revision, suggested the elevation of subfamily Urodacinae to the family rank, and considered Heteroscorpioninae a subfamily of Ischnuridae. Heteroscorpioninae was formally elevated to the family rank by Lourenço (1996a), and Urodacinae, by Prendini (2000). As a result of a detailed cladistic analysis, Prendini (2000, 2003b) considered families Heteroscorpionidae and Urodacidae to be sister groups, although an al-ternative topology was available. Soleglad & Fet (2003b) questioned the results of Prendini (2000) but nevertheless retained the monophyly of Heteroscorpion and Urodacus pending more detailed analysis; they recognized two valid monotypic subfamilies, Heteroscorpioninae and Urodacinae, under Urodacidae. Our …

New Data On Distribution And Ecology Of Seven Species Of Euscorpius Thorell, 1876 (Scorpiones: Euscorpiidae), Marco Colombo
Euscorpius
The author observed seven species of Euscorpius in 1999–2005 (E. alpha, E. sicanus, E. tergestinus, E. concinnus, E. naupliensis, E. italicus, and E. flavicaudis) in their natural environment, mainly in Italy but also in France, Switzerland, and Greece. Ecology of these species is discussed as well as predatory behavior occasionally observed in nature. This work provides new data on the distribution and ecology of European Euscorpiidae.
Review Of Tunisian Species Of The Genus Buthus With Descriptions Of Two New Species And A Discussion Of Ehrenberg’S Types (Scorpiones: Buthidae), František Kovařík
Review Of Tunisian Species Of The Genus Buthus With Descriptions Of Two New Species And A Discussion Of Ehrenberg’S Types (Scorpiones: Buthidae), František Kovařík
Euscorpius
Buthus chambiensis, sp. n. and Buthus dunlopi, sp. n. from Tunisia are described. Presented is also a key to four Tunisian species of the genus Buthus. The males of B. chambiensis, sp. n. and B. paris (C. L. Koch, 1839) have narrower chela than the females, which distinguishes them from B. tunetanus (Herbst, 1800) and B. dunlopi, sp. n. Uniformly yellowish mesosoma and very narrow chela of pedipalps distinguish B. chambiensis, sp. n. from Buthus paris (C. L. Koch, 1839). Morphologically closest to B. chambiensis sp. n. is Buthus barcaeus Birula, 1909, comb. n. …

Scorpions Of Gaziantep Province, Turkey (Arachnida: Scorpiones), Ayşegül Karataş, Mehmet Çolak
Euscorpius
This study includes the results of the field studies in Gaziantep Province, which is located in the south-southeastern Anatolia, Turkey. In 1998–2005, 112 scorpion specimens were collected in this area. They belong to five species of the family Buthidae (Androctonus crassicauda, Compsobuthus matthiesseni, Leiurus quinquestriatus, Mesobuthus eupeus nordmanni), and one species of Scorpionidae (Scorpio maurus fuscus). Information about these species is provided; ecological notes are included.
The Genus Auyantepuia González-Sponga, 1978 Is Confirmed As A Synonym Of Broteochactas Pocock, 1893 (Scorpiones: Chactidae), Michael E. Soleglad, Victor Fet
The Genus Auyantepuia González-Sponga, 1978 Is Confirmed As A Synonym Of Broteochactas Pocock, 1893 (Scorpiones: Chactidae), Michael E. Soleglad, Victor Fet
Euscorpius
The genus Auyantepuia González-Sponga, 1978 is confirmed as a synonym of Broteochactas Pocock, 1893 (Scorpiones: Chactidae). It was correctly synonymized with Broteochactas by Francke & Boos (1986) and listed as such by Soleglad & Fet (2003) but resurrected by Lourenço & Araújo (2004). We reconfirm that the generic name Auyantepuia, based on the type species Broteochactas scorzai Dagert, 1957 from Venezuela, is a synonym of Broteochactas, based on the type species Broteochactas nitidus Pocock, 1893 from Trinidad. All other seven “short-fingered” species from French Guiana and Brazil, classified by Lourenço & Araújo (2004) under Auyantepuia, belong to …

Taxonomic Position Of Species Of The Genus Buthacus Birula, 1908 Described By Ehrenberg And Lourenço, And Description Of A New Species (Scorpiones: Buthidae), František Kovařík
Euscorpius
Lectotypes are designated for Androctonus (Leiurus) leptochelys Ehrenberg, 1829, Androctonus (Leiurus) thebanus Ehrenberg, 1828 and Androctonus (Leiurus) macrocentrus Ehrenberg, 1828. In recent papers the latter two species have been regarded as synonyms of Buthacus leptochelys, however its type series is composed of seven specimens that in reality belong to three species. The type series of Androctonus leptochelys includes specimens belonging to Buthacus leptochelys and Buthacus spatzi (Birula, 1911), and the type series of Androctonus macrocentrus includes specimens belonging to Buthacus leptochelys and Buthacus tadmorensis (Simon, 1892). In order to preserve stability, I designate …

Taxonomic Position Of The Genus Simonoides Vachon Et Farzanpay, 1987, And Description Of A New Species Of Orthochirus Karsch From Iran (Scorpiones, Buthidae), František Kovařík, Victor Fet
Euscorpius
Simonoides Vachon et Farzanpay, 1987 is synonymized with Orthochirus Karsch, 1891. Lectotype is designated for Simonoides farzanpayi Vachon et Farzanpay, 1987. Orthochirus sobotniki Kovařík, 2004 is synonymized with Orthochirus farzanpayi (Vachon et Farzanpay, 1987), comb. n. Orthochirus gruberi, sp. n. (Iran) is described and dis-tinguished from all other Iranian species of the genus on a combination of two characters, the presence of rows of granules with internal and external granules on the movable fingers of pedipalps and hirsuteness of the entire me-tasoma and telson.
Observations On Prey-Capture Behavior Of Androctonus Crassicauda (Olivier, 1807) (Scorpiones: Buthidae) In Northern Iraq, Alexander K. Stewart
Observations On Prey-Capture Behavior Of Androctonus Crassicauda (Olivier, 1807) (Scorpiones: Buthidae) In Northern Iraq, Alexander K. Stewart
Euscorpius
Modern studies of scorpion prey-capture behavior have included several genera from a variety of habitats and have demonstrated that scorpions have a limited, yet similar, repertoire of reactions towards their prey. These experiments, however, by necessity have dealt with scorpions under the ecologically artificial conditions of an indoor laboratory. The experimental design presented here included both indoor and outdoor laboratory experiments to study the prey capture in Androctonus crassicauda (Olivier, 1807). Thirty indoor and twenty outdoor experiments recorded scorpion activities from initial prey recognition to prey ingestion. By experimenting with this indigenous species in its harsh environment (an outdoor laboratory, …

Euscorpius
Although Mesobuthus caucasicus was listed from Turkey in the literature, information about this species was confused and needed confirmation. Distribution of M. caucasicus is studied and new geographical records are given. As a result of field studies, M. caucasicus is confirmed from three certain localities in Turkey. In addition, some bioecological information is provided.

The Scorpions (Arachnida: Scorpiones) Of Sint Eustatius, Lesser Antilles, Rolando Teruel, Hannah Madden
Euscorpius
In the present note, we revise the scorpion fauna of the small island of Sint Eustatius, in the Lesser Antilles. A total of two families, three genera and three species are confirmed to occur there: the buthids Centruroides barbudensis (Pocock, 1898) and Isometrus maculatus (DeGeer, 1778), and the scorpionid Oiclus purvesii (Becker, 1880). These include the first record of the occurrence in Sint Eustatius of the family Scorpionidae and the genus Oiclus Simon, 1880, as well as the first published findings of I. maculatus since 1942. A key to the easy identification of all three species is provided.
A New Scorpion Genus (Scorpiones: Vaejovidae) From Mexico, Michael E. Soleglad, Victor Fet
A New Scorpion Genus (Scorpiones: Vaejovidae) From Mexico, Michael E. Soleglad, Victor Fet
Euscorpius
A new vaejovid genus from Mexico, Franckeus, gen. nov., is described based on unique neobothriotaxy. Species placed in this genus are from the Vaejovis “nigrescens” group (previously called the “nitidulus” group). Six species comprise this new genus, distributed throughout Mexico (mainland as well as Baja California Sur): Franckeus nitidulus, F. rubrimanus, F. platnicki, F. minckleyi, F. kochi and F. peninsularis. A new species of the Vaejovis “nigrescens” group, Vaejovis davidi, sp. nov., is also described.
A New Trichobothrial Character For The High-Level Systematics Of Buthoidea (Scorpiones: Buthida), Victor Fet, Soleglad E. Michael, Graeme Lowe
A New Trichobothrial Character For The High-Level Systematics Of Buthoidea (Scorpiones: Buthida), Victor Fet, Soleglad E. Michael, Graeme Lowe
Euscorpius
The high-level systematics and phylogeny of the scorpion superfamily Buthoidea are unresolved. A new, formerly undetected character is reported here: the relative alignment of d3 trichobothrium and DMc carina on the pedipalp patella. This and other characters are discussed in the context of possible high-level divisions of Buthoidea. Based on this analysis, we suggest a breakdown of Buthoidea into six proposed tentative phylogenetic groups: Buthus group, Ananteris group, Isometrus group, Charmus group, Uroplectes group, and Tityus group.

Redescription Of The Mexican Scorpion Centruroides Hoffmanni Armas, 1996 (Scorpiones: Buthidae), Eliézer Martín-Frías, Luis F. De Armas, Jorge F. Paniagua-Solís
Euscorpius
The Mexican scorpion Centruroides hoffmanni Armas, 1996 is redescribed, based on adults of both sexes. It is readily diagnosed by its medium size, dark brown two-banded tergites and brown marbling on carapace, appendages and metasoma, pectinal tooth counts, the shape of the female basal plate of the pectines, development of metasomal carinae, and shape of the telson and subaculear tubercle. The geographical distribution of this species ranges from southeastern Oaxaca to southwestern Chiapas, Mexico. It was originally compared with Centruroides thorelli (Kraepelin, 1891), but actually it seems to be closely related to C. infamatus (C. L. Koch, 1845) and C. …
