Vestigial Serrula In Scorpion Genera Paravaejovis, , Smeringurus And Vejovoidus (Scorpiones: Vaejovidae), Victor Fet, Michael E. Soleglad, Michael S. Brewer, David P. A. Neff, Michael L. Norton
Victor Fet
The presence of vestigial serrula on the ventral edge of the cheliceral movable finger is established for vaejovid genera Paravaejovis, Paruroctonus, Smeringurus, and Vejovoidus. Detailed descriptions and SEM images illustrating the various manifestations of this interesting cheliceral structure are provided for many species of these four genera. A brief systematic overview of this structure as it exists in Recent scorpions is also presented.

The Scorpion Sternum: Structure And Phylogeny (Scorpiones: Orthosterni), Michael E. Soleglad, Victor Fet
Victor Fet
The structure of the sternum of all major Recent scorpion groups is analyzed in detail. Based on this analysis, two fundamental sternum types are identified, described and illustrated, type 1 and type 2. These sternum types are distinguished by criteria based on external and internal structural features. The sternum types described herein are offered as a replacement for the various characterizations used throughout the last 140 years which emphasize only gross overall shape and proportions. Phylogenetic and taxonomic ramifications of these new sternal types are discussed. The Carboniferous fossil scorpion Palaeopisthacanthus schucherti Petrunkevitch is assigned to sternum type 1. The …

Contributions To Scorpion Systematics. Ii. Stahnkeini, A New Tribe In Scorpion Family Vaejovidae (Scorpiones: Chactoidea), Michael E. Soleglad, Victor Fet

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), comb. nov. (=Serradigitus allredi); and Stahnkeus polisi (Sissom et Stockwell, 1991), …
A Note On The Scorpions From The Pirin Mountains, Southwestern Bulgaria (Scorpiones: Buthidae, Euscorpiidae), Rolando Teruel, Victor Fet, Luis F. De Armas
A Note On The Scorpions From The Pirin Mountains, Southwestern Bulgaria (Scorpiones: Buthidae, Euscorpiidae), Rolando Teruel, Victor Fet, Luis F. De Armas
Victor Fet
In the present note, four scorpion species are recorded from the Pirin Mountains in southwestern Bulgaria, including the first records for Bulgaria of both Mesobuthus gibbosus (Brullé, 1832) (Buthidae) and the “mingrelicus complex” of the genus Euscorpius Thorell, 1876 (Euscorpiidae) (the latter based upon an undetermined species). Also, E. hadzii Caporiacco, 1950 and another undetermined species of Euscorpius belonging to the “carpathicus complex” are recorded from Pirin. The taxonomic affinities of the taxa are discussed, as well as some biogeographical considerations about the scorpions of this poorly studied mountainous area.
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
Victor Fet
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 Scorpion From A Peatbog: The First Arthropod Fossil From The Late Viséan Of The Moscow Coal Basin, Victor Fet, Michael E. Soleglad, Yulia V. Mosseichik, Dmitry E. Shcherbakov
A Scorpion From A Peatbog: The First Arthropod Fossil From The Late Viséan Of The Moscow Coal Basin, Victor Fet, Michael E. Soleglad, Yulia V. Mosseichik, Dmitry E. Shcherbakov
Victor Fet
This note describes a fossil fragment from the Upper Viséan (ca. 330 Ma), of the Moscow Coal Basin (Novgorod Region, Russia). The fossil is identified as the cuticle of a single leg segment (left femur) of a scorpion (Arachnida: Scorpiones), without any further taxonomic placement. The anatomical details of the fragment are given, along with ecological considerations. It is the first fossil scorpion record from Russia.
