Holotype. HNHM /15911 adult. No. 10, Ioannina County, Lakmos Mts., open brook and rocky beech forest at the pass of the Chaliki-Anilio road, 1610m, N39°43.008’ E21°11.602’, leg. J Kontschán, D. Murányi, T. Szederjesi, Zs. Ujvári, 0 9.0 5.2011.
Paratypes. HNHM /15912 one adult ex., locality and date same as that of the holotype., HNHM /15913 one adult ex., No. 27, Evrytania County, Timfristos Mts., alpine grassland around the ski course, 2km W of Mt. Timfristos, 1865m, N38°56.516’ E21°48.412’, leg. J. Kontschán, D. Murányi, T. Szederjesi, Zs. Ujvári, 0 7.0 5.2011.
Derivatio nominis. From Greek (?ρεɩος = highlander), refers to the mountain habitat of the new species.
Diagnosis. Length 61–113 mm, diameter 4–6 mm, setae closely paired. Pigmentation lacking. First dorsal pore 5/6. Clitellum on 25–34, tubercles 29–32. Male pore on 15, large. Nephridial pores irregularly alternate between b and above d. Two pairs of vesicles in 11, 12; spermathecae 9/10–10/ 11 in M. Calciferous glands without welldeveloped diverticula in 10–12. Hearts in segments 6–11, nephridial bladders sausage-shaped.
External characters. Holotype 100 mm long and 5 mm wide. Number of segments 159. Paratypes 61–113 mm long and 4–6 mm wide. Number of segments 104–111. Colour pale, pigmentation lacking. Prostomium epilobous ½, closed. First dorsal pore at intersegmental furrow 5/6. Setae closely paired. Setal arrangement behind clitellum: aa: ab: bc: cd: dd = 16:1.5:8:1:23. Male pores on segment 15, surrounded by a glandular crescent. Nephridial pores irregularly alternate between setal line b -d. Clitellum on segments 25–34. Tubercula pubertatis on segments 29–32 (Fig. 3). Genital papillae on segments 25, 26, 28–34 ab.
Internal characters. Septa 6/7–8/9 slightly thickened. Testes and funnels paired in segments 10–11, covered with perioesophageal testis sac. Seminal vesicles in 11, 12. Spermathecae in 9/10, 10/11 with external openings near the mid-dorsal line. Calciferous glands in segments 10–12 without distinct diverticula. Paired hearts appear in segments 6–11, with a pair of small extraoesophageal vessel in 12. Nephridial bladders simple, sausage-shaped. Crop in segments 15–16, and gizzard in segments 17–18. Typhosolis biramous, longitudinal musculature fasciculate.
Remarks. The new species belongs to the E. grandis species group as defined by Zicsi & Csuzdi (1986), which is represented by two species in Greece, E. ebneri and E. kattoulasi. E. oreophila sp. nov. differs from both species by its longer clitellum and the position of the tubercula pubertatis.
Zicsi & Michalis (1981) examined two syntypes of Eophila ariadne Michaelsen, 1928 described from Greece. On the basis of presence of nephridial bladders, they removed ariadne from synonymy with Helodrilus partiarchalis (Rosa, 1893) and placed it into the genus Allolobophora. However the simple sausage-shaped nephridial bladders, lack of detached calciferous diverticula and fasciculate musculature clearly place it in the E. grandis group.
