Summary

A new scorpion species, Vaejovis grahami sp. nov. is described. This small, dark brown species is found in the Santa Rita Mountains, Santa Cruz County, Arizona, USA. It is most similar to V. vorhiesi Stahnke and V. deboerae Ayrey. The pedipalp fixed finger usually has 5 inner denticles (ID) and the movable finger has 6, like in most other southern Arizona Vaejovis.

syntropinae

The endemic North American vaejovid scorpion subfamily Syntropinae Kraepelin, 1905, is redefined and its component genera revised, based on a simultaneous phylogenetic analysis of 250 morphological characters and 4221 aligned DNA nucleotides from three mitochondrial and two nuclear gene markers. Tribe Stahnkeini Soleglad and Fet, 2006, is removed from Syntropinae. Tribe Paravaejovini Soleglad and Fet, 2008, and subtribe Thorelliina Soleglad and Fet, 2008, are abolished: Paravaejovini Soleglad and Fet, 2008 = Syntropinae Kraepelin, 1905, syn. nov.; Thorelliina Soleglad and Fet, 2008 = Syntropinae Kraepelin, 1905, syn. nov. Eleven genera, six newly described, are recognized within Syntropinae: Balsateres, gen. nov.; Chihuahuanus, gen. nov.; Kochius Soleglad and Fet, 2008; Konetontli, gen. nov.; Kuarapu Francke and Ponce-Saavedra, 2010; Maaykuyak, gen. nov.; Mesomexovis, gen. nov.; Paravaejovis Williams, 1980; Syntropis Kraepelin, 1900; Thorellius Soleglad and Fet, 2008; Vizcaino, gen. nov. Hoffmannius Soleglad and Fet, 2008, is abolished: Hoffmannius Soleglad and Fet, 2008 = Paravaejovis Williams, 1980, syn. nov. Lissovaejovis Ponce-Saavedra and Beutelspacher, 2001 [nomen nudum] = Paravaejovis Williams, 1980, syn. nov. Ten species, formerly placed in Hoffmannius, are transferred to Paravaejovis: Paravaejovis confusus (Stahnke, 1940), comb. nov.; Paravaejovis diazi (Williams, 1970), comb. nov.; Paravaejovis eusthenura (Wood, 1863), comb. nov.; Paravaejovis flavus (Banks, 1900), comb. nov. [nomen dubium]; Paravaejovis galbus (Williams, 1970), comb. nov.; Paravaejovis gravicaudus (Williams, 1970), comb. nov.; Paravaejovis hoffmanni (Williams, 1970), comb. nov.; Paravaejovis puritanus (Gertsch, 1958), comb. nov.; Paravaejovis spinigerus (Wood, 1863), comb. nov.; Paravaejovis waeringi (Williams, 1970), comb. nov. Paravaejovis schwenkmeyeri (Williams, 1970), comb. nov., is removed from synonymy. Four species, formerly placed in Kochius, are transferred to Chihuahuanus, gen. nov.: Chihuahuanus cazieri (Williams, 1968), comb. nov.; Chihuahuanus crassimanus (Pocock, 1898), comb. nov.; Chihuahuanus kovariki (Soleglad and Fet, 2008), comb. nov.; Chihuahuanus russelli (Williams, 1971), comb. nov. Four species, formerly placed in Kochius, Thorellius, or Vaejovis C.L. Koch, 1836, are transferred to Mesomexovis, gen. nov.: Mesomexovis atenango (Francke and González-Santillán, 2007), comb. nov.; Mesomexovis oaxaca (Santibáñez-López and Sissom, 2010), comb. nov.; Mesomexovis occidentalis (Hoffmann, 1931), comb. nov.; Mesomexovis subcristatus (Pocock, 1898), comb. nov. Mesomexovis variegatus (Pocock, 1898), comb. nov., is reinstated to its original rank as species. Four subspecies are newly elevated to species: Kochius barbatus (Williams, 1971), stat. nov.; Kochius cerralvensis (Williams, 1971), stat. nov.; Kochius villosus (Williams, 1971), stat. nov.; Mesomexovis spadix (Hoffmann, 1931), comb. et stat. nov. Three subspecies are synonymized: Vaejovis diazi transmontanus Williams, 1970 = Paravaejovis diazi (Williams, 1970), syn. nov.; Vaejovis bruneus loretoensis Williams, 1971 = Kochius villosus (Williams, 1971), syn. nov.; Vaejovis hoffmanni fuscus Williams, 1970 = Paravaejovis hoffmanni (Williams, 1970), syn. nov

Abstract

Several scorpions of the genus Vaejovis in Arizona are restricted in range to mountain-top forests. These scorpions, informally referred to as the “vorhiesi complex” are very similar morphologically, but their geographic distribution has attracted the attention of several researchers, resulting in the description of a few new species in recent years. However, these species were described from small sample sizes and were diagnosed with questionable characters that were not sufficiently analyzed. This study evaluates the morphology of scorpions of the “vorhiesi complex” from seven regions in Arizona to verify the validity of the species and their accompanying diagnoses. Morphological characters examined include morphometrics, hemispermatophores, size and shape of subaculear tubercles of the telson vesicle, pectinal tooth counts, pedipalp chela denticle counts, metasomal setal counts, development of metasomal carinae, and tarsal spinule counts. New diagnoses are given for previously described species (V. vorhiesi Stahnke 1940V. lapidicola Stahnke 1940V. paysonensis Soleglad 1973V. cashi Graham 2007 and V. deboerae Ayrey 2009), which are considered valid, based on the morphological evidence gathered. A new species ofVaejovisV. electrum, is described from the Pinaleño Mountains in Arizona.

ZooKeys-177-001-g002Abstract

A new scorpion species is described from the Inyo Mountains of California (USA). The presence of a strong subaculear spine, along with other characters, places the new species withinWernerius, an incredibly rare genus that until now consisted of only two species. Werneriuinyoensis sp. n. can be most easily distinguished from the other members of the genus by smaller adult size, femur and pedipalp dimensions, and differences in hemispermatophore morphology. Previous studies have suggested that the elusive nature of this genus may be attributed to low densities and sporadic surface activity. Herein, we provide another hypothesis, that Wernerius are primarily subterranean. Mitochondrial sequence data are provided for the holotype.

Abstract
A new species in the vorhiesi group of Vaejovis C.L. Koch, 1836 (Vaejovidae Thorell, 1876), which appears to be endemic to the Hualapai Mountains near Kingman, Arizona, is described and illustrated. Vaejovis tenuipalpus, n. sp., the 11th species in the vorhiesi group, is compared to morphologically similar species, including V. jonesi Stahnke, 1940, V. lapidicola Stahnke, 1940, V. vorhiesi Stahnke, 1940, and V. deboerae Ayrey, 2009. The new species possesses the most slender pedipalp chelae in the vorhiesi group. New distribution records and a comprehensive distribution map are provided for all Arizona members of the group.

Summary
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.

Abstract:

Multivariate analyses of morphological characters provide strong evidence that a highland Vaejovis from the Sierra de los Ajos, a Madrean ‘sky island’ in northern Sonora, Mexico, represents a distinct new species of the V. vorhiesi group. This new species is described and compared to other geographically adjacent species of the V. vorhiesi group, named
V. bandido, and brief notes on ecology are provided. Results from this study provide evidence that multivariate analysis of morphological characters is a powerful tool to delimit small and otherwise cryptic scorpion species.

ZooKeys-270-021-g005Abstract

A new species of the vorhiesi group of Vaejovis C.L. Koch, 1836, Vaejovis brysoni sp. n., is described from the Santa Catalina Mountains in southern Arizona. Vaejovis deboerae Ayrey also inhabits this mountain range, making this the first documented case of two vorhiesi group species distributed on the same mountain. When compared to all other vorhiesi group species, Vaejovis brysoni sp. n. is distinct based on several combinations of morphological characters and morphometric ratios.

Abstract

A new scorpion species is described from the Spring Mountain Range near Las Vegas, Nevada. The new species appears to be geographically isolated from other closely related species ofUroctonites Williams & Savaryand Pseudouroctonus Stahnke. We tentatively place the new species in Pseudouroctonus and provide detailed descriptions and illustrations of type material. We compare the new species to 17 congeneric taxa, briefly discuss the taxonomic history ofPseudouroctonus, and provide DNA barcodes for two paratypes to assist ongoing research on the systematics of family Vaejovidae.
