Dendrobaena cevdeti sp. nov.

( Figure 1 A,B)

Holotype. HNHM /16607, Sivas-Divriği-Karakuzulu village, Hıdırlık Mezrası, open area, under oak trees, 1568 m a.s.l., 39°23’N 37°54’E, 19.05.2009, leg. Y. Coşkun, N. Coşkun.

Paratypes. HNHM /16601 2 ex., Sivas-Divriği-Karakuzulu village, Hıdırlık Mezrası, under oak trees, 1532 m a.s.l., 39°23’N 37°54’E, 16.05.2009, leg. Y. Coşkun.

Derivatio nominis. The species is named in honour of Cevdet Coşkun who kindly invited us to collect samples at his village.

Diagnosis. Length 40–48 mm, diameter 3–4 mm, setae distant. Colour pale, at the head slightly red-violet. First dorsal pore in 5/6. Clitellum on 1/2 24 –34, tubercles on 31–32. Male pore on 15, surrounded by glandular crescents. Nephridial pores irregularly alternate between b and above d. Three pairs of vesicles in 9,11,12; spermathecae two pairs in 9/10, 10/11, open near d. Calciferous glands in 11–12. Hearts in segments 6–11, nephridial bladders simple, sausage-shaped.

External characters. Holotype 48 mm long and 4 mm wide. Number of segments 138. Paratypes 40–46 mm long and 3–4 mm wide. Number of segments 128–136. Colour pale, at the head slightly red-violet. Prostomium epilobous, 1/3 closed. First dorsal pore at intersegmental furrow 5/6. Setae distant. Setal arrangement behind clitellum: aa: ab: bc: cd: dd = 2.8:1:2.1:1.4:4. Male pores on segment 15, surrounded by glandular crescents, protruding into the neighbouring segments. Nephridial pores irregularly alternate between setal line b–d. Clitellum on 1/2 24 –34. Tubercula pubertatis on 31–32. Glandular tumescence on 27–32 ab.

Internal characters. Septa 6/7–8/9 and 12/13–14/15 slightly thickened. Testes and funnels paired in 10–11, covered with perioesophageal testis sac. Three pairs of seminal vesicles in 9,11, and 12. Spermathecae two pairs in 9/10, 10/11 with external openings near the setal line d. Calciferous glands in 11–12. Paired hearts appear in 6–11. Nephridial bladders simple, sausage-shaped. Crop in 15–16, and gizzard in 17–18. Typhlosolis anchor-shaped. Longitudinal musculature is of pinnate type.

Remarks. The position of the tubercles on 31–32 makes the new species similar to D. faucium ( Michaelsen, 1910) . However, D. faucium is characterized by a clitellum stretching on 26–32 (1/2 24 –34 in D. cevdeti ) and its spermathecae open in the setal line c (d in D. cevdeti ).
