Berlandina Dalmas, 1922

Type species: Gnaphosa plumalis O. Pickard-Cambridge, 1872 from Palestine.

Diagnosis. Berlandina differs from Gnaphosa (the only other genus of Gnaphosinae in the region) by having larger posterior median eyes, a thick embolus (filamentous or at least tapering near tip in Gnaphosa ) and in having no epigynal scape (present in Gnaphosa ). From all other Gnaphosidae genera occurring in East Palaearctic, Berlandina can be easily distinguished by having a serrated keel on the chelicerae ( Figs 61–62 ).

Comments. Although the genus encompasses 31 species, it was never subdivided into subgenera or species groups. Here we divide the 14 species from Central Palaearctic into five species groups according to the shape of male palp and epigyne. Subdivision to species groups are provisional. Diagnoses of these groups are given below in the text.
