Belongs within: Basalhaplogynae.

The Oonopidae, goblin spiders, are a family of very small ground-hunting spiders, most diverse in tropical regions. In members of the subfamily Gamasomorphinae, the abdomen is covered by hardened dorsal and ventral scuta (Jocqué & Dippenaar-Schoeman 2007).

Characters (from Jocqué & Dipppenaar-Schoeman 2007): Very small; six eyes present, grouped close together, or eyes absent; legs with two claws, biserially dentate on an onychium; abdomen often with dorsal and ventral scuta; posterior tracheae anteriorly positioned; ecribellate; haplogyne, female genitalia a sclerotised slit composed of two distinct elements associated with both anterior and posterior walls of bursa.
