ED208A57B26A524DFB8989F4FBDBFE8A.taxon	diagnosis	Diagnosis. Amaurobius is generally very similar to Taira, Callobius, Cybaeopsis etc, but differs from other genera by a different shape of retrolateral tibial apophysis (RTA) and the branches of dorsal tibial apophysis (DTA). The RTA of Amaurobius is wider than long and blunt (Figs 1 D – E, 2 F – G, 3 D, 4 D – E, 5 F – G, 6 D) (longer than wide, somewhat pointed in Callobius, longer than wide, blunt or bifurcate in Cybaeopsis) and the exterior branch of dorsal tibial apophysis (eDTA) is longer than interior branch of dorsal tibial apophysis (iDTA) (Figs 1 C, 1 E, 2 E, 2 G, 3 C – D, 4 C – E, 5 E – G, 6 C – D) (eDTA shorter than iDTA in Taira). Additionally, the median apophysis is relatively thin and hook-shaped (Figs 1 C – E, 2 E – G, 3 A, 4 D – E, 5 F – G, 6 A) (broad in Callobius and Cybaeopsis). Epigynes of Amaurobius and Taira have widely separated lateral teeth but differ from Callobius and Cybaeopsis, which have two lobes almost connected to each other. Amaurobius songi sp. nov.
