Heterothele villosella
A dwarf tarantula from Tanzania with a leg span of around 6cm. It is very fast but has no urticating hairs, and specialist dealers rate it in the easiest suitability band among Old World species.
Heterothele villosella was described by Strand in 1907 with its type locality at Amani in Tanzania. The genus Heterothele comprises small species in the subfamily Ischnocolinae, and this one is a dwarf that reaches only about 6cm in leg span as an adult. Its muted chestnut to brown colouring gives it its common name. Little is published about the species beyond its original description, and specimen records are limited to a handful from Tanzania. In captivity it is treated as fossorial and kept on diggable substrate with a hide. Its speed is the main thing to watch, but specialist dealers place it in the easiest suitability band and it is often introduced as a starter Old World species. Being a dwarf it needs only small prey, and small crickets or fruit flies suffice even for adults. It has no urticating hairs.
