Anthroherpon sinjajevina sp. n.

Type material. Holotype male labeled as follows: “ MONTENEGRO, Sinjajevina Mt, Njegovude, village Rudanca, Blažova pećina, 1470 m, 25.06.2013, leg. I. Njunjić” (white label, printed) / “ HOLOTYPUS Anthroherpon sinjajevina sp.n. I. Njunjić, M. Perreau & D. Pavićević det. 2014“ (red label, printed), ( MNHN). Paratypes: 5♂ 10♀, 18.07.2010. ( MNHN, CINJ, CMPR, CDPV), 7♂ and 12♀, same cave, 25.06.2013, leg. I. Njunjić ( MNHN, CINJ, CMPR, CDPV). All paratypes are labeled with white, printed locality labels and with red printed labels “ PARATYPUS Anthroherpon sinjajevina sp.n. I. Njunjić, M. Perreau & D. Pavićević det. 2014”.

Diagnosis. Habitus illustrated in Fig. 1 . Distinct from the other species of the group by the following characters: second antennomere approximately two times shorter than the first one. Sides of pronotum convergent behind the anterior third of the pronotum length, the sides parallel on the basal fourth of the pronotum length. Elytral surface with microreticulation between punctures. Pronotum without symmetrical dorsal impressions. Parameres shorter than median lobe (setae excluded) with a constriction in the preapical region and with acute apex ( Fig. 6 c).

Description. Body length 5.6 to 5.9 mm (HT 5.71 mm). General morphology leptodiroid; head wider than pronotum, elytra physogastric; eyeless; wingless, and depigmented.

Head: hypognathous, wider in the anterior part and wider than the pronotum, HL 1.13-1.22 mm (HT 1.19 mm), HW 0.73-0.76 mm (HT 0.73 mm). Surface rough with evident microreticulation visible without scanning electron microsopy and with sparse and short pubescence. Penultimate maxillary palpomere approximately 1.2 times longer than the last one. Antennae 1.20 (males) or 1.05 (females) longer than the whole body. Second antennomere very short in comparison to the other antennomeres, approximately 2 times shorter than the first one. Last antennomere approximately 2 times (male) or 1.7 times (females) longer than the penultimate.

Sides convergent behind the anterior third of the pronotum length, the sides parallel on the basal fourth of the pronotum length. Dorsal surface microreticulated and with a few punctures randomly disposed. Short and very sparse setae are randomly disposed mostly in the posterior part.

Mesothoracic pedunculus around 2 times wider than long and with stronger microreticulation than the pronotum.

Elytra elliptic, with maximum width in the mid-section, mean EL/EW 1.70 (males; HT 1.73), 1.60 (females). Surface with regularly spaced punctation and with microreticulation between the punctation. Pubescence short, dense and semi-erected.

Legs: long, slender, femora gradually thicken in the basal parts, tibias straight. Male protarsi with five protarsomeres, female protarsi with four protarsomeres, mesotarsi and metatarsi with five tarsomeres in both sexes. Tarsi not dilated, tarsal empodium with two setae.

Aedeagus: median lobe thicker at the base and with triangular apex in dorsal view ( Fig. 6 a), strongly curved in the basal region then more or less straight and flat in the central and apical region in lateral view ( Fig. 6 b). Parameres shorter than the median lobe (setae excluded) with a constriction in the preapical region, with acute apex and three apical setae ( Fig. 6 c). Endophallus without sclerotized structures.

Female genitalia: abdominal ventrite VIII with a short and narrow anterior expansion (fig. 6d). Urite IX without appendicular parts. Spermatheca: weakly sclerified, C shaped, short and slightly widened in the apical region.

Distribution. A. sinjajevina n. sp. is presently known only from the type locality Blažova pećina, situated near the village Rudanca near Njegovuđe, on Sinjajevina Mt, Montenegro. Blažova pećina is a small and simple cave consisting in two chambers divided by a 9 m deep vertical section ( Fig. 3). The bottom of the first chamber is covered with leaf litter, branches and old trunks while the rest of the channel is covered with rock debris and blocks of 0.3 to 0.8 m.

Etymology. From Sinjajevina Mountain, where the type locality is situated.
