The Gnaphosidae, flat-bellied ground spiders, are a diverse group of mostly ground-running spiders that are characterised by the presence of enlarged spigots on the lateral spinnerets. They produce egg sacs that are usually papery and attached to a firm surface (Jocqué & Dippenaar-Schoeman 2007). Among the major subgroups of the Gnaphosidae, Hemicloea species are very flat, thin spiders with a sclerotised ring on the posterior lateral spinnerets. Members of the genus Herpyllus possess male palps with a basally broadened embolus and elongate median apophysis, and internal female genitalia consisting of two elongate tubular spermathecae with basal lobes. The similar genus Scotophaeus has a hooklike median apophysis on the male palp and terminal bulbs on the spermathecae in the female. Species of Eilica have anteriorly produced chelicerae possessing two or three translucent laminae on the retromargin, and often have a pattern of light and dark areas on the abdomen. Trachyzelotes is a genus found primarily around the Mediterranean characterised by a cluster of stiff setae on the anteromedian face of the chelicerae.

Characters (from Jocqué & Dippenaar-Schoeman 2007): Small to medium-sized; eight eyes present, with posterior median eyes flattened; endites obliquely depressed; legs with two tarsal claws; ecribellate; anterior spinnerets parallel, large, cylindrical and usually well separated, without distal ring; their piriform gland spigots greatly enlarged, with flattened base and shaft, and slit-like opening; entelegyne.
