New Analysis Of The Genus Pseudouroctonus With The Description Of Two New Species (Scorpiones: Vaejovidae), Richard F. Ayrey, Michael E. Soleglad Jan 2016

New Analysis Of The Genus Pseudouroctonus With The Description Of Two New Species (Scorpiones: Vaejovidae), Richard F. Ayrey, Michael E. Soleglad

Euscorpius

Two new species of Pseudouroctonus are described from southeastern Arizona, USA, Pseudouroctonus santarita, sp. nov. from the Santa Rita Mountains and P. kremani, sp. nov. from the Santa Catalina Mountains. These new species are closely related to P. apacheanus (Gertsch et Soleglad, 1972). A combination of morphological differences in the hemispermatophore, the mating plug, and several morphometric-based characters are identified as diagnostic. New substructures are identified for the mating plug.


New Species Of Vaejovis From The Whetstone Mountains, Southern Arizona (Scorpiones: Vaejovidae), Richard F. Ayrey, Michael E. Soleglad Jan 2016

New Species Of Vaejovis From The Whetstone Mountains, Southern Arizona (Scorpiones: Vaejovidae), Richard F. Ayrey, Michael E. Soleglad

Euscorpius

A new scorpion species, Vaejovis troupi sp. n., is described and placed in the “vorhiesi” group of the genus Vaejovis. Based on a recent molecular analysis of Bryson et al. (2013), this species is shown to be related to V. vorhiesi and V. grahami. Two of three diagnostic characters found in this new species are the presence of six inner denticles (ID) on the pedipalpal fixed and movable fingers, and a unique arrangement of trichobothria on the external surface of the pedipalp patella. This species was found in an isolated montane habitat in the Whetstone Mountains, Cochise County, Arizona.


A New Species Of Vaejovis From Chaparral Habitat Near Yarnell, Arizona (Scorpiones: Vaejovidae), Richard F. Ayrey Jan 2016

A New Species Of Vaejovis From Chaparral Habitat Near Yarnell, Arizona (Scorpiones: Vaejovidae), Richard F. Ayrey

Euscorpius

A new scorpion species, Vaejovis grayae sp. nov. is described and placed in the “vorhiesi” group of the genus Vaejovis. This small brown species is found near Yarnell, Arizona, USA. It appears most similar to V. trinityae Ayrey and V. crumpi Ayrey et Soleglad. It can be distinguished from the other members of the “vorhiesi” group by a unique combination of non-overlapping morphological characters and multilocus DNA data (Bryson et al., 2013). The pedipalp fixed finger has 6 ID denticles and the movable finger has 7, like most other northern Arizona “vorhiesi” group species. Another characteristic of this species is ...


A New Species Of Vaejovis From The Mogollon Rim Of Northern Arizona (Scorpiones: Vaejovidae), Richard F. Ayrey Jan 2016

A New Species Of Vaejovis From The Mogollon Rim Of Northern Arizona (Scorpiones: Vaejovidae), Richard F. Ayrey

Euscorpius

A new scorpion species, Vaejovis trinityae sp. nov. is described. This small brown species is found along the Mogollon Rim above Strawberry, Arizona. This is the first description of a new species of the “vorhiesi” group scorpions whose DNA phylogenetic analysis was published (Bryson et al., 2013); based on DNA data, the new species is most related to V. lapidicola Stahnke and V. crumpi Ayrey et Soleglad. It represents one of the “twenty-seven geographically cohesive lineages inferred from the mtDNA tree”. A unique characteristic of this species is that it exhibits arboreal behavior, being frequently found on Ponderosa pine trees.


Reproduction And Birth In The “Vorhiesi” Group Of The Genus Vaejovis (Scorpiones: Vaejovidae). Part I. Clutch Size, Richard F. Ayrey Jan 2016

Reproduction And Birth In The “Vorhiesi” Group Of The Genus Vaejovis (Scorpiones: Vaejovidae). Part I. Clutch Size, Richard F. Ayrey

Euscorpius

A total of 2,287 newborn scorpions were counted and photographed on 100 females of all 12 described species of the “vorhiesi” group of the genus Vaejovis (Scorpiones: Vaejovidae) found in Arizona, USA, and several undescribed species. Average clutch size for the “vorhiesi” group and for each individual species is reported. The data clearly shows that the larger species have more young, per parturition, than the smaller species. Representative photographs are presented for each species discussed.
