Diagnosis
The new species differs from all Palearctic congeners by the widely separated lateral margins not converging posteriorly, and widely separated receptacles leaving an open atrium with parallel rims (vs receptacles almost touching and lateral margins converging posteriorly). Furthermore, it differs by the presence of short copulatory ducts, almost vertical and in line with the receptacles (vs bent copulatory ducts parallel to the receptacles). The species most similar to G. qamsarica sp. nov. are: G. cumensis Ponomarev, 1981, G. halophila Esyunin & Efimik, 1997, G. jucunda Thorell, 1875, G. saurica Ovtsharenko, Platnick & Song, 1992, G. ukrainica Ovtsharenko, Platnick & Song, 1992 and G. zeugitana Pavesi, 1880. The last one is the most similar in that the copulatory ducts are almost in line with the receptacles and the receptacles are widely separated. However, G. qamsarica sp. nov. differs from G. zeugitana by the parallel lateral margins and the rectangular atrium (vs triangular).
Etymology
The specific epithet is an adjective and refers to the type locality of the new species.
