Diagnosis ( Condé 1947a; Condé & Bareth 1996)

Troglomorphic species. Antennae with 46–52 antennomeres; abundant sheet-shaped olfactory chemoreceptors in cupuliform organ; protruding frontal process with tubercular setae. Pronotum with 1+1 ma, 3+3–4+4 la, 2+2 lp macrosetae; mesonotum with 1+1 la, 2+2 lp macrosetae; metanotum with 2+2 lp macrosetae; barbed notal macrosetae; clothing setae abundant, completely barbed. No ventral tibial macrosetae; unequal claws with large crests, posterior claw with a backward overhang. Urotergite III with 1+1 (0+1) la macrosetae; urotergite IV with 1+1 la macrosetae; urotergites V–VII with 1+1 la, 3+3 post macrosetae; urotergite VIII with 5+5 post macrosetae; abdominal segment IX with 9+9–11+11 post macrosetae; urosternite I with 17+17–22+22, urosternites II–VII with 13+13–19+19, urosternite VIII with 3+3–6+6 macrosetae. Male with lateral expansions of posterior margin occupied by an area of glandular g 1 setae in adults (no expansions in juveniles and small expansions in young males), subcylindrical appendages without glandular a 2 setae; females with long subcylindrical appendages without glandular a 2 setae.

Remarks

The studied material (see Table S 2 in Supplementary Material) allowed the addition of information to the diagnosis. The specimens from Njegoš pećina, Njeguši (Kotor, Montenegro) and Đatlo pećina, Lebršnik, Gacko ( Bosnia and Herzegovina) revealed new diagnostic characters in SEM microscopy: antennomeres with a whorl of thin gouge sensilla, 40–47 µm long with an external transversal striped surface in a V pattern ( Figs 181–182, 184 ), claws with large lateral crest with ventral longitudinal grooves separated by reticulate surfaces ( Figs 183, 185–186 ). The first urosternite of the adult male has lateral expansions, bearing plenty of glandular g 1 setae ( Figs 187–188 ), and abundantly long and completely barbed urosternal macrosetae ( Figs 189, 192 ), like the stylar setae ( Fig. 190 ), and similar to but thinner than the cercal macrosetae ( Fig. 191 ).
