Diagnosis.

( Bareth and Condé 2001; Sendra et al. 2020 b): Epicuticle smooth at high magnifications. Antennae with 23–26 antennomeres; five simple olfactory chemoreceptors in cupuliform organ; distal whorl of 8–11 gouge sensilla that are 25 µm long; slightly protruding frontal process with non-tuberculated to slightly tubercular setae. Pronotum with 1 + 1 ma, 3 + 3 la, 2 + 2 lp macrosetae; mesonotum with 1 + 1 ma, 3 + 3 la, 2 + 2 lp macrosetae; metanotum with 1 + 1 ma, 1 + 1 (2 + 1) la, 2 + 2 lp macrosetae; long, barbed notal macrosetae; abundant barbed notal clothing setae. Two ventral tibial macrosetae; subequal claws (ratio 1.05–1.1) with large but narrow lateral crests, posterior claw with a small backward overhang (Fig. 1 a View Figure 1 ). Urotergites I – II with 1 + 1 post macrosetae; urotergite III with 2 + 2 post macrosetae; urotergites IV – V with 1 + 1 la, 5 + 5 post macrosetae; urotergites VI – VII with 2 + 2 (2 + 1) la, 5 + 5 post macrosetae; urotergite VIII with 6 + 6 post macrosetae; abdominal segment IX with 8 + 8 post macrosetae; urosternite I with 7 + 7 (Fig. 1 b View Figure 1 ), urosternites II – VII with 5 + 5, urosternite VIII with 2 + 2 macrosetae (Fig. 1 c View Figure 1 ); stylus setae with a few distal barbs (Fig. 1 d View Figure 1 ). Male with glandular g 1 setae, subcylindrical appendages with glandular a 1 setae; female appendages similar to those of male (Fig. 1 b View Figure 1 ).

Habitat and distribution.

Slightly cave-adapted species that has hitherto been found in caves from two geographically distant karst regions in the Balkan Peninsula – the Predbalkan in Bulgaria (Lyaskovskata Cave, the type locality) and the Karst Plateau in Slovenia (two caves near the town of Sežana). Here, we re-establish the species from its type locality (Arbanashkata Cave, also known as Lyaskovskata Cave), as well as from three additional caves in Bulgaria located in distinct geographical regions: the Eastern Stara Planina Mountains, the Shumen Plateau, and the Strandzha Mountains. As a result, the known range of the species is extended by approximately 200 km to the southeast and 100 km to the northeast of the type locality (Fig. 21 View Figure 21 ).
