Etymology. The new specific epithet is derived from Latin adjective “ exiguus ” which means short, small, referring to the short pygofer ventral appendage.

Diagnosis. This species can be distinguished from the other species the genus by the shortened pygofer ventral appendage, presence of a tooth-like process on the style and by the well-developed dorsal apodeme.
