Holotype: HNHM/15847 About HNHM , Albania, Sarandë district , Çikë Mts , Borsh, Ixuor Spring in the village, N40°03.686’ E19°51.462’, 105m, 11.05.2006., leg. L. DÁNYI, J. KONTSCHÁN, D. MURÁNYI GoogleMaps . Paratype: HNHM/16019 About HNHM , locality and date same as that of the holotype .
Etymology: The specific epithet refers to the country of the type locality.
Diagnosis. Length 91–102 mm, diameter 7–7.5 mm, setae distant. Colour grey, at the head slightly red-violet. First dorsal pore in 9/10. Clitellum on 29–37, tubercles on 29–37. Male pore on 15, small. Nephridial pores irregularly alternate between b and above d. Four pairs of vesicles in 9–12; spermathecae six pairs in 6/7–11/12 open near c. Calciferous glands in 10–12 with lateral diverticula in 10. Hearts in segments 6–11, nephridial bladders ocarina-shaped.
Description: Holotype: length 91 mm, diameter 7.5 mm. Number of segments 148. Paratype: 102 mm long and 7 mm wide. Number of segments 142. Colour grey, the head is slightly red-violet on dorsum. Prostomium epilobous. First dorsal pore at the intersegmental furrow 9/10. Setae distantly standing. Setal formula after the clitellum: aa:ab:bc:cd:dd = 2.25:1.38:1.31:1:4.06 ( Fig. 4 View Figs 2–5 ). Male pores on segment 15 between setae b–c, small. Nephridial pores irregularly alternate between setal line b -d. Clitellum on segments 29–37. Tubercula pubertatis on segments 29–37 ( Fig. 5 View Figs 2–5 ).
Internal characteristics. Septa 6/7–14/15 slightly thickened. Testes and funnels paired in segments 10–11, covered with perioesophageal testis sacs. Seminal vesicles present in segments 9–12, small in segment 10. Spermathecae six pairs in 6/7–11/12 with external openings near setal line c. Calciferous glands in segments 10–12 with lateral diverticula in segment 10. Last pair of hearts in segment 11, with a pair of small extraoesophageal vessel in 12. Nephridial bladders ocarina-shaped. Crop in segments 15–16, and gizzard in segments 17–18. Typhosolis simple, lamelliform. Longitudinal muscle layer is of pinnate type.
Remarks. The new species with six pairs of spermathecae belongs to the Oc. lissaensis species group, however differs from the other species in the position of the clitellum and tubercles (Table 2.) and furthermore in the presence of red violet pigmentation. Other species with six pairs of spermathecae and red-violet pigmentation are Oc. croaticus ( ROSA, 1895) and Oc. argoviensis (BRETSCHER, 1899), but Oc. albanicus sp. n. differs from both species by the position of the clitellum (27–34, 28–35 and 29–37, respectively).
