Dysdera brignolii group

The brignolii group, sensu Dunin (1992: 137).

Diagnosis. The group can be recognized by the combination of the following characters: the strongly prominent semi-oval median crest, the psembolus 1.2–1.6 times longer than the tegulum, and the posterior apophysis situated in the middle part of the bulb.

Composition. Five species are included: D. brignolii Dunin, 1989 , D. kugitangica Dunin, 1992 , D. kusnetsovi Dunin, 1989 , D. nenilini Dunin, 1989 (all from Turkmenistan) and D. mikhailovi sp. nov. ( Tajikistan).

Comments. Dunin (1989) assigned representatives of the brignolii group, i.e. D. kusnetsovi , D. nenilini and D. brignolii , together with some species of the aculeata group, viz. D. tartarica , D. pococki and D. limitanea , to the tartarica group based on a characteristic leg spination, such as: coxae and patellae without spines, femora of all legs with spines. Later, Dunin (1992) put D. brignolii , D. kugitangica , D. kusnetsovi and D. nenilini to the brignolii group without providing a diagnosis, which is given here (see above). The brignolii species group has a very limited range, being known only from Turkmenistan (Kugitangtau and Kopet Dag Mt. Ranges, Karakum Desert and Sarykamysh Hollow) and the neighboring western part of Tajikistan (Hissar Mt. Range).
