Heterogenella bigibbata Mamaev & Berest, 1991

Fig. 8 A

This species, previously known only from the type locality in Ukraine (Mamaev & Berest 1991), is here reported from two sites in south and central Sweden. Swedish specimens of H. bigibbata are in line with the redescription of this species by Jaschhof (1998) as well as with an unpublished drawing of the genitalia of the male holotype, which the senior author made in 2007. Heterogenella biggibata is distinguished from the congeneric species by short, almost circular gonostyli (↓); the ninth tergite lacking a T-shaped sclerotization (as is present in H. linearis Yukawa); and the ventral emargination of gonocoxae bordered by small, densely setulose swellings (↓).
