Redescription. Body yellowish-brown, BL: 3.87–3.93 mm, L: 2.99–3.00 mm in males and BL: 3.96–4.02 mm, L: 3.07–3.13 mm in females.

Head ( Fig. 13 ) longer than (HL1) or about as long as (HL 2 male, HL 1 female) the pronotum or slightly shorter (HL 2 female), slightly narrower than pronotum, HW/PW: 0.77–0.88. Head longer than wide, HL1/HW: 1.36–1.60, HL2/HW: 1.13–1.33. Males antennomeres length (mm): (1) 0.14, (2) 0.28, (3) 0.25, (4) 0.25, (5) 0.30, (6) 0.28, (7) 0.35–0.39, (8) 0.17, (9) 0.39, (10) 0.33–0.36 and (11) 0.39–0.42. AL males: 3.16–3.20 mm. Male antennomere relative length/relative maximum width ratios: (1) 2, (2) 5, (3) 4.5, (4) 5, (5) 6.3, (6) 5.6, (7) 3.7, (8) 3, (9) 4.5, (10) 3.5 and (11) 4.5. Females antennomeres length (mm): (1) 0.14, (2) 0.30, (3) 0.22, (4) 0.22, (5) 0.28, (6) 0.22–0.25, (7) 0.30–0.32, (8) 0.14, (9) 0.28–0.29, (10) 0.28 and (11) 0.30. AL females: 2.71 mm. Female antennomere relative length/relative maximum width ratios: (1) 2, (2) 4.9, (3) 4, (4) 4.7, (5) 5.4, (6) 4.7, (7) 3.7, (8) 3, (9) 3.5, (10) 2.8 and (11) 3.3.

Pronotum ( Fig. 22 ) approximately as long as wide in males, PL/PW: 1.00–1.02 and slightly longer than wide in females, PL/PW: 1.06.

Elytra ( Fig. 18 ) elongate, EL/EW: 1.88–1.94 in males, 1.60–1.62 in females. The length of the basal apophysis of the metanotum (alacrista) ( Figs 18, 19, 21 , 26 ) is approximately 13–14% of elytral length.

Spines along the lateral outer margin of protibia reaching approximately apical half of protibial length ( Fig. 17 ). Male protarsi slender, slightly dilated ( Fig. 17 ) and as long as the pronotum, PRTL/PL: 1.

Aedeagus 0.67–0.72 mm long. Inner sac of median lobe with developed chitinized structures, as is illustrated ( Figs 14, 15 ). Female genitalia as in illustrations ( Figs 24, 25, 27 ).

Biology: Subterranean species, so far known exclusively from the type locality.

Distribution: Bosnia and Herzegovina, Vitez, Kruščica pećina ( Fig. 28 ).
