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. 20 ). This new species is mainly characterized by the presence of four pairs of dorsal setae (three discal and one preapical) on elytra. This character is present so far only in A. kevser .

Description. L: 5.05 mm (HT)–5.4 (PT) mm, TL: 4.75 mm (HT)–4.95 (PT) mm. Head relatively large, elongate, with maximum width in middle, distinctly longer than wide (index HL/HW 1,36 (HT)–1.40 (PT)), almost as wide as pronotum, sparsely pubescent. Frontal furrows weakly impressed, ending before half of head length. Two pairs of long supraorbital setae present; neck constriction distinct; genae gently convex. Clypeus and labrum with three pairs of setae, outer pairs longer. Antennae length 3.14 mm (HT)– 3.22 mm (PT), scape as long as pedicel, almost as long as terminal antennomere.

Pronotum elongate, as long and wide as head, with maximum width in anterior third, basal part distinctly narrower than anterior (index PL/PW 1.52 (HT)–1.62 (PT)), sparsely pubescent, setae long, suberect; median furrow weakly marked, visible in the middle part of pronotum. Propleura visible from dorsal aspect only in basal half. Anterior angles of pronotum distinctly protruding, obtuse, 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 1.71 (HT)–1.78 (PT)), with maximum width behind middle; elytral surface covered with very sparse, long and erect pubescence; striae absent. Site of stria 3 with four (three 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. Pore 5 located nearer to pore 4 than to pore 6.

Legs long, slender, densely pubescent.

Female genitalia: as on Fig. 35 .

Male unknown.

Etymology. Topotypic, refering to the type locality, Rumija mountain range in southern Montenegro.

Topographic location and ecology. Mountain range Rumija , with its highest peak Rumija (1594 m a.s.l.), is situated between Skadar lake and Adriatic see. This , the most southern Montenegrian mountain range, was speleologically almost unexplored. Researches conducted during years 2005 and 2006 were focused on the surrounding of the peak Rumija and saddle Bijela Skala (903 m a.s.l.). Six pits were discovered and explored.

Phoenix pit ( Fig. 42 ): entrance of the pit is situated in large (ca 400 x 400 m) slope sinkhole field near the peak Rumija, in altitude 1105 m a.s.l. Entrance part of the pit is formed by ca 15 meters deep depression which continues to the expanding schaft ending in the depth of 70 m by large hall (ca 12 x 13 m). Total depth of the pit is 78 meters. During the visits (in May and August) almost the whole bottom of the hall was filled with snow and ice. Air temperature at the bottom was about 2o C. Type specimens were found in the depth of ca 70 meters, in wet clay fallen on snow cone from the surface, together with carabid beetles Neotrechus suturalis ssp. (Schaufuss, 1864) and Laemostenus (Antisphodrus) cavicola ssp. (Schaum, 1858). On wet walls near the bottom there were observed also leptodirine beetles Anthroherpon matulici (Reitter, 1903) , Anthroherpon taxi ssp. (Müller, 1913) and Blattochaeta sp. Reitter, 1910.

Distribution. so far known only from the type locality, Phoenix abyss on Rumija Mts., south Montenegro.
