Description

External characters: Both specimens cut in half. Length ~ 42 mm, diameter 2.5 mm. Number of segments ~105. Pigmentation pinkish on the head. Prostomium epilobous ½ opened. First dorsal pore at intersegmental furrow 14/15. Setae distantly standing. Setal arrangement behind clitellum: aa: ab: bc: cd: dd = 1.75:1.25:1.13:1:2.5. Male pores minute on segment 15. Nephridial pores irregularly alternate between setal line b and above d. Clitellum on segments 25–30. Tubercula pubertatis on 1/ n 25, 26 –½29. Glandular tumescence on segments 9 ad, 10, 11 abcd.

Internal characters: No dissepiments notably thickened. Testes and funnels paired in segments 10–11, covered by perioesophageal testis sac in segment 10 and 11. Three pairs of seminal vesicles in 9, 11 and 12. Two pairs of spermathecae in 9/10, 10/11 with external openings in setal line d. Calciferous glands in segment 11 and 12, without distinct diverticula. The last pair of hearts in 11, with a pair of extraesophageal vessels in 12. Nephridial bladders are biscuit-shaped. Crop in segments 15–16, and gizzard in segments 17–18. Typhlosolis simple lamelliform, large. The cross section of the longitudinal muscle layer of pinnate type.

Material examined: HNHM /15799 1 ex., HNHM /15800 1 ex., Turkey, Istranca Mts, 253 m, N41°49.300′ E27°45.085′, L. Dányi, Z. Erőss, Z. Fehér, J. Kontschán, D. Murányi, 6 April 2007. HNHM /15813 1 ex., Turkey, Istranca Mts, 538 m, N41°44.667′ E27°39.279′, L. Dányi, Z. Erőss, Z. Fehér, J. Kontschán, D. Murányi, 6 April 2007.

Remarks: The only characters that distinguish this questionable species from D. byblica are the number of vesicles (3 vs. 4) and the somewhat longer tubercula (1/ n 25, 26 –½29 vs. 26–28). To reveal its exact identity, revision of all D. byblica synonyms and similar species is necessary. However, we can’t exclude that these specimens represent a new species.
