Flat and Spineless Ground Spiders

Enlarged anterior eyes on distinct mount; males with completely coiled tip of median apophysis, females with coiled ducts.

Retrolateral tibial apophysis of male pedipalp enormously elongated, extending almost to the tip of the palpal cymbium. Females with concomitant elongation of the epigynum, with an anterior hood situated just behind the pedicel, and separated from the remainder of the epigynum by easily extensible cuticle.

Total absence of leg spines; tarsi (especially those of leg IV) distinctively thick and cylindrical.

Differ from members of Rebilus and Morebilus in having teeth on the tarsal proclaws.

Small, extremely flat with leg coxae separated by sclerotized extensions of the epimeric sclerite.

This group includes all trachycosmid species that can currently not be referred to a genus.

The absence of leg spines readily separates members of this genus from those of Trachytrema and Trachyspina; males have the apex of the cymbium prolonged into a functional conductor.

Similar to Tachytrema, but the body is lighter in color (with a pale gray abdomen), the carapace, abdomen and legs are sparsely covered with short, thick, club setae, the anterior tibiae have leg spines, and all the legs spines are distinctively short

Males have a paracymbium (a distinct hook at the basal retrolateral edge of the cymbium), that is absent in Trachycosmus, females have smaller, less squared epigyna and retain some (albeit short and weak) leg spines.
