Anthroherpon cecai sp. n.

Type material. Holotype male labeled: „ MONTENEGRO, Durmitor Mt, village Mala Crna Gora, Poda, Crna jama (= Jama u Podu), 1900 m, 0 7.08.1993, leg. A. Milosavljević“ (white label, printed) / „ HOLOTYPUS Anthroherpon cecai sp.n. I. Njunjić, M. Perreau & D. Pavićević det. 2014“ (red label, printed), ( MNHN). Paratypes: 3♀, same date as holotype ( MNHN, CDPV); 1♂, same locality, 0 3.08.1992, leg. A. Milosavljević, 1♂, same locality, 0 5.07.1991, leg. S. Ognjenović ( MNHN, CDPV). All paratypes are labeled with white, printed locality labels and with red printed labels „ PARATYPUS Anthroherpon cecai sp.n. I. Njunjić, M. Perreau & D. Pavićević det. 2014“.

Diagnosis. Habitus illustrated in Fig. 2 . Distinct from the other species of the group by the following characters: second antennomere approximately two times shorter than the first one. Lateral sides of the pronotum parallel on the basal fifth of the pronotum length. Pronotum with two symmetric dorsal impressions on the anterior half of the pronotum length (with variable extension and deepness, absent in some specimens). Elytral surface microreticulated between the punctation. Parameres as long as the median lobe (setae excluded), with preapical constriction and with rounded apex (fig. 7c).

Description. Body length from 6.59 to 7 mm. (HT 6.59 mm). General morphology leptodiroid; pronotum slightly wider than the head, wide elytra; eyeless; wingless and depigmented.

Head: hypognathous, wider in the anterior part, HL 1.34- 1.35 mm (HT 1.35 mm), HW 0.81- 0.85 mm (HT 0.81 mm). Surface shiny, microreticulated and with sparse and short pubescence. Penultimate maxillary palpomere approximately 1.4 times longer than the last one. Antennae 1.20 (males) or 1.00 (females) longer than the whole body. Second antennomere approximately 2 times shorter than the first one. Last antennomere approximately 1.7 times (males) or 1.6 times (females) longer than the penultimate. Antennal formula: see Table 1.

Sides convergent in the anterior third and parallel on the basal fifth of the pronotum length. Dorsal area with two symmetric impressions more or less extended transversally (the conformation is variable according to the specimen and absent in some specimens), located on the anterior quarter of the pronotum length. Surface microreticulated, with short and sparse setae regularly disposed.

Mesothoracic pedunculus short, around 2.8 times wider than long and with stronger microreticulation than the pronotum.

Elytra elliptical, with maximum width in the mid-section, EL/EW approximately 1.6 (males; HT 1.74), 1.65 (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 with five protarsomeres, female with four protarsomeres, mesotarsi and metatarsi with five tarsomeres in both sexes. Tarsi not dilated, tarsal empodium with two setae.

Aedeagus with median lobe elongated, slightly wider in basal part and with rounded apex in dorsal view ( Fig. 7 a), strongly curved in the basal region then more or less straight and flat in the central and apical region in lateral view ( Fig. 7 b). Parameres as long as the median lobe (apical setae excluded), with a preapical constriction, rounded at the apex, and with three long apical setae ( Fig. 7 c). Endophallus without sclerotized structures.

Female genitalia: abdominal ventrite VIII with a short and narrow anterior expansion ( Fig. 7 d). Urite IX without appendicular parts. Spermatheca: weakly sclerified, C shaped, short and slightly widened in the apical region.

Etymology. After our colleague and friend Aleksandar Milosavljević-Ceca, speleologist (Belgrade) and finder of the first specimens of this species.

Associated fauna. Leonhardella (L.) antennaria antennaria Apfelbeck 1907 and Neobisium sp. ( Pseudoscorpiones ).

Distribution. A. cecai sp. is presently known only from the type locality: Crna jama pit (- 121 m). All Anthroherpon specimens were collected on the very bottom while Leonhardella and Pseudoscorpiones were found on the walls from the entrance to the bottom of the pit.
