Anqasha

Anqasha is a recently erected South American genus of the family Theraphosidae established on the basis of morphological and biogeographic evidence that segregated a clade of high-altitude Andean species from previously encompassing genera. Members are associated with the montane and puna biomes of the central Peruvian Andes, where they occupy rocky slopes, crevices, and tussock grasslands at elevations considerably higher than those tolerated by most Neotropical theraphosids.

Species within the genus are comparatively small-bodied relative to lowland theraphosids, an ecomorphological pattern common among high-altitude Andean arachnids, and they exhibit life-history traits consistent with cooler, more thermally variable environments, including reduced growth rates and extended intermolt intervals. Adult leg span is modest, generally falling in the range of 2.5 to 4 inches. Retreats are typically constructed within natural crevices and beneath stones, with silk used primarily to line the refuge rather than to form extensive surface structures.

As New World theraphosids, Anqasha species possess urticating setae on the dorsal opisthosoma and rely on a combination of refuge concealment and setal flicking for defense. Venom is of no documented medical significance, and temperament is typically described as retiring. The integument frequently bears subtle metallic or copper-toned setae that contribute to the genus's diagnostic appearance.

The genus remains taxonomically young, and ongoing revisionary work continues to refine the boundaries between Anqasha and related Andean lineages such as Hapalotremus and Bistriopelma. Natural-history data are comparatively sparse, and the genus is rarely encountered outside of targeted high-altitude field surveys, contributing to its scarcity in private collections.
