Diagnosis ( Condé 1947a)

Troglomorphic species. Antennae with 22–29 antennomeres; cupuliform organ with seven or eight complex olfactory chemoreceptors. Protruding frontal process with tubercular setae. Pronotum with 1+1 ma, 2+2 la, 2+2 lp macrosetae; mesonotum with 1+1 ma, 2+2–2+3 la, 2+2 lp macrosetae; metanotum with 1+1 ma, 1+1 la, 2+2 lp macrosetae; long, barbed notal setae; abundant barbed notal clothing setae. Two ventral tibial macrosetae; unequal claws (1.3–1.5) with large lateral crests, posterior claw with a backward overhang. Urotergites I–III with 1+1 post macrosetae; urotergite IV with 1+1 la, 2+2–3+3 post macrosetae; urotergite V with 1+1 la, 4+4–5+5 post macrosetae; urotergites VI–VII with 1+1–2+2 la, 5+5 (4+5) post macrosetae; urotergite VIII with 6+6 macrosetae; abdominal segment IX with 8+8–8+9 macrosetae; urosternite I with 7+7, urosternites II–VII with 5+5, urosternite VIII with 2+2 macrosetae. Male with an area of glandular g 1 setae, subcylindrical and slightly enlarged appendages with glandular a 1 setae; female appendages like male appendages.

Remarks

The 17 specimens studied, from four caves in the Dinaric Mountains ( Bosnia and Herzegovina) (see Table S 2 in Supplementary Material), allowed us to clarify some characters: five complete antennae preserved show 28–29 antennomeres, elongated antennomeres with a distal whorl of 12–14 long gouge sensilla ( 30–32 µm) ( Figs 131–132 ); cupuliform organ with seven or eight spheroidal olfactory chemoreceptors, each with a jagged fold surrounding a central coniform structure covered by a highly visible, multiperforated polygonal net surface ( Figs 125–130 ). Protruding frontal process with tubercular setae. Surface of epicuticle reticulate ( Fig. 133 ). Smooth tarsal subapical setae and calcars with long barbs from base, pretarsus claws with large lateral crests ( Fig. 134 ). Furthermore, they show a wider range in the number of urotergal macrosetae than mentioned in the diagnosis above.
