Kochius hirsuticauda
(Banks, 1910)
Kochius hirsuticauda is a in the Vaejovidae, first described as Vaejovis hirsuticauda by Banks in 1910 and later transferred to the Kochius. The specific epithet "hirsuticauda" refers to a hairy tail (cauda), a distinctive morphological feature. It is a North American species with documented observations primarily from the southwestern United States. The genus Kochius was established relatively recently, separating several species previously placed in Vaejovis based on phylogenetic and morphological evidence.

Identification
Distinguished from other Kochius and sympatric vaejovids by the conspicuously hairy metasoma referenced in its name. Separation from the former Vaejovis (sensu lato) requires examination of trichobothrial patterns on the and subtle differences in metasomal segment proportions. The combination of geographic range and the hairy tail characteristic is diagnostic in the field.
Habitat
Arid and semi-arid environments of the southwestern United States; specific microhabitat preferences are poorly documented but likely include rocky substrates and soil burrows typical of ground-dwelling vaejovid scorpions.
Distribution
Southwestern United States; precise range boundaries are not well defined in published literature. Documented observations span portions of Arizona, New Mexico, and adjacent regions.

Taxonomic History
Originally described by Nathan Banks in 1910 as Vaejovis hirsuticauda. The was transferred to the Kochius in 2013 when Soleglad and Fet erected this genus to accommodate a clade of "vorhiesi group" species previously placed in Vaejovis. This reclassification was based on integrated phylogenetic and morphological analysis.
Etymology
The specific epithet hirsuticauda combines Latin 'hirsutus' (hairy, bristly) with 'cauda' (tail), directly describing the ' most conspicuous morphological feature.
