A new \u3cem\u3eVaejovis\u3c/em\u3e from the Mogollon Highlands of northern Arizona (Scorpiones: Vaejovidae)

A new scorpion species, Vaejovis halli sp. nov., is described. This relatively small, brown new species is found on Mount Ord in the Mazatzal Mountains along the Mogollon Rim of northern Arizona. The new species appears most similar to V. vorhiesi Stahnke and V. deboerae Ayrey. The most distinguishing characteristic of this new species is the number of inner denticles (ID) found on the pedipalp fingers with six on the movable finger and usually five on the fixed finger, which more closely correlates with Vaejovis species from the mountains of southern Arizona rather than those geographically closer in northern Arizona

A New Species of \u3cem\u3eVaejovis\u3c/em\u3e from the Patagonia Mountains, Southern Arizona (Scorpiones: Vaejovidae)

A new scorpion species, Vaejovis patagonia sp. nov. is described and placed in the “vorhiesi” group. This small, dark brown species is found near Patagonia, Arizona. It is geographically closest to V. troupi Ayrey & Soleglad, V. grahami Ayrey & Soleglad and V. vorhiesi Stahnke. Those three species are found in a triangle surrounding the Patagonia Mountains, the locality of Vaejovis patagonia. The pedipalp fixed finger has 5 ID denticles and the movable finger has 6, like most, but not all, of the other southern Arizona Vaejovis. Carapace of female is shorter than metasomal segment V

\u3cem\u3eSerradigitus miscionei\u3c/em\u3e (Scorpiones: Vaejovidae), a new species from southern Arizona

A new scorpion species, Serradigitus miscionei, is described, placed in the genus Serradigitus Stahnke, 1974. These are small reddish-brown scorpions found on vertical surfaces, in the San Pedro River system and other river systems in southern, Arizona

An anomaly of pectinal organs in \u3cem\u3eVaejovis lapidicola\u3c/em\u3e (Scorpiones: Vaejovidae)

Among specimens of Vaejovis lapidicola Stahnke, one female was found to have abnormally shaped pectines, both with only distal pectinal teeth. This rare, possibly teratological anomaly is documented and discussed

A new species of \u3cem\u3eVaejovis\u3c/em\u3e from chaparral habitat near Yarnell, Arizona (Scorpiones: Vaejovidae)

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 its unique Arizona chaparral habitat

A new species of \u3cem\u3eVaejovis\u3c/em\u3e from the Mogollon Rim of northern Arizona (Scorpiones: Vaejovidae)

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

A new species of \u3cem\u3eVaejovis\u3c/em\u3e from Mingus Mountain, northern Arizona (Scorpiones: Vaejovidae)

A new scorpion species, Vaejovis elii sp. n., is described. This small, dark brown species is found on Mingus Mountain, Yavapai County, northern Arizona, USA. It is geographically closest to V. crumpi Ayrey & Soleglad. We compare it to that species and two other species found in northern Arizona. The pedipalp fixed finger has 6 ID denticles and the movable finger has 7, like in most, but not all, of the other northern Arizona Vaejovis. Carapace of female is longer than metasomal segment V

\u3cem\u3eSerradigitus miscionei\u3c/em\u3e, the first vaejovid scorpion to exhibit parthenogenesis

Thelytokous parthenogenesis (all-female broods) is strongly suggested for the vaejovid species Serradigitus miscionei (Vaejovidae) from southern Arizona, USA. This conclusion is based on the examination of 187 specimens and 15 broods, all determined as females

Sky Island \u3cem\u3eVaejovis\u3c/em\u3e: A new species (Scorpiones: Vaejovidae)

A new scorpion species, Vaejovis deboerae, sp. nov., is described and placed in the “mexicanus” group of the genus Vaejovis. They are small light yellowish brown scorpions found in the Santa Catalina Mountains, one of the sky islands of southern Arizona. They are closely related to V. vorhiesi Stahnke. The original description of V. vorhiesi Stahnke, 1940 and redescription (Graham, 2007), state that they are found in the Huachuca and Santa Catalina Mountains of southern Arizona. No specimens from the Santa Catalina Mountains were included in the redescription based on the lack of adequate material. The redescription stated “…the Santa Catalina Mountains scorpions definitely warrant further study if specimens become available.” This description of a new species is based on ample specimens now being available

Reproduction and birth in the “vorhiesi” group of the genus \u3cem\u3eVaejovis\u3c/em\u3e (Scorpiones: Vaejovidae). Part I. Clutch size

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
