Genus Oedignatha Thorell, 1881

Type species: Oedignatha scrobiculata Thorell, 1881 , by monotypy.

Diagnosis. The genus is similar to Koppe Deeleman-Reinhold, 2001 in having massive chelicerae and a simplistic genitalic organ structure, but can be distinguished by the carapace surface with granules or pits (absent in Koppe ), clypeus with a conical hump (vs. slight or absent in Koppe ), intercoxal sclerites not enlarged (present in Koppe ), and the posterior window of the epigyne without a membranous or partly sclerotized flap (present in Koppe ) (cf. Fig. 2A–D with Deeleman-Reinhold 2001: figs 375–425).
