Ischnocolus is a genus of tarantulas that was first described by Anton Ausserer in 1871.[2] This tarantula genus includes some of the smallest in the family.[3]

Diagnosis

Males of this genus can be distinguished by the palpal bulb morphology, which owns a slightly bent apical end. Females can be distinguished by the morphology of the spermatheca, which is made up of two twisted receptacles.[3]

Species

As of May 2026 it contains nine species, found in Europe, Asia, Africa, and Brazil:[1]
