Lohaj , Lakota , Quéinnec , Pavićević & Čeplík des. 2014” ( CDP, CJL, CRL, CRM) .

Diagnosis. A medium-sized trechine beetle with aphaenopsoid features: head and pronotum elongate; elytra ovoid, strongly narrowed at the base, obviously wider than head and pronotum; body depigmented, strongly flattened ( Fig. 21 View FIGURES 20 – 22 ). This new species is mainly characterized by the presence of posterior pair of supraorbital seta, anterior pair missing. This character is present only in A. albanicus sp. nov.

Description. L: 4.7–5.75 mm, TL: 4.35–5.35 mm. Head relatively large, elongate, with maximum width behind middle, slightly longer than wide, index HL/HW in HT 1.16, almost as wide as pronotum, densely pubescent. Frontal furrows deep, long, exceeding half of head length. Posterior pair of long supraorbital setae present, anterior pair missing; neck constriction weakly marked; genae gently convex. Clypeus with four pairs of setae, labrum with three pairs of setae, outer pairs longer. Antennae length in HT 3.71 mm, scape as long as pedicel, shorter than terminal antennomere.

Pronotum elongate, longer than head, with maximum width in anterior third, basal part distinctly narrower than anterior (index PL/PW in HT 1.41), sparsely pubescent, setae short, suberect; median furrow distinctly marked. Propleura not visible. Anterior angles of pronotum not protruding, rounded, posterior angles obtuse. Lateral furrows developed, deep, with one pair of anterolateral setae, situated in apical fourth of pronotal length.

Elytra subovate elongate, distinctly longer than wide (index EL/EW in HT 1.82), with maximum width in posterior third; elytral surface covered with dense, short and erect pale pubescence; striae absent. Site of stria 3 with three (two discal and one preapical) setae, humeral group of umbilicate pores not aggregated, first anterior pore of humeral group isolated and situated before the level of the first discal seta.

Legs long, slender, densely pubescent.

Male genitalia ( Fig. 29 View FIGURES 23 – 30 ): aedeagus very long and slender, gradually narrowed towards apex in lateral aspect, sagittal aileron large, endophallus without distinct copulatory piece. Parameres long and slender, with two long setae at apex.

Female genitalia: as on Fig. 36 View FIGURES 31 – 36 .

Etymology. Patronymic, dedicated to our dear friend Roman Mlejnek from Pardubice ( Czech Republic), enthusiastic caver and biospeleologist, discoverer of this new species.

Topographic location and ecology. Mountain range Kučke planine (other frequently used name for these mountains is Žijovo) with its highest peak Surdup (2184 m a.s.l.) is situated northeast of Montenegrian capital Podgorica and Skadar lake, near the Albanian borders ( Fig. 43 View FIGURE 43 ). Geographically , this area is edged in the east and southeast by the river Cijevna and is the borderline with Albania. From the southwest it is the Zeta plain. In the west by the rivers Morača and Mala Rijeka and in the north by the rivers Veruša and Bukumirsko lake and Rikavačko lake. Speleological researches during years 2007 and 2010 were focused on the surrounding of the peak Šila (2022 m a.s.l.).

Pit Prometheus: entrance of pit (ca 2 x 4 m) is situated in altitude 1690 m, above the shallow sinkhole. Pit is formed by a vertical shaft, up to the depth of about 125 m, ended by bottom (ca 10 x 9 m) formed by rock debris. Air temperature at the bottom was about 2o C. The type specimens, holotype and paratypes (4 exs.) were collected at the depth of about 130 m, in rock debris. Together with Adriaphaenops mlejneki sp. nov. there were also other arthropods present, such as the leptodirine beetle Anthroherpon latipenne gottli (Zariquiey, 1927) , as well as a undetermined genus and species of specialized pseudoscorpion.

Second known locality is unnamed pit in altitude 2030 m a.s.l. This simple pit with vertical shaft is 60 m deep. Two paratype specimens were found at the bottom of the pit, in rock debris with black soil.

Third known locality is Milići snježnica (=snow cave). Entrance of the cave (ca 8 x 3 m) is situated near the chalet Toke, village Kučka Korita, in altitude 1 320 m, on the bottom of shallow sinkhole ( Fig. 44 View FIGURE 44 ). Cave is about 20 m long, fully lighted, bottom is covered with permanent ice and air temperature is 2–3 o C. Paratype female specimen was collected at the end of the cave, on the cave wall.

Distribution. so far known only from two pits and one cave located on Kučke planine Mts., south-eastern Montenegro.
