Diagnosis. Length 90–130 mm, diameter 3–4 mm, setae widely paired. Colour greiysh, pigmentation lacking. First dorsal pore in 5/6. Clitellum on ½ 26, 26–33, ½ 34, tubercles on 30–32. Male pore large on 15. Nephridial pores irregularly alternate between b and above d. Two pairs of seminal vesicles in 11,12; spermathecae two pairs in 9/10–10/11 open in M. Well-developed calciferous diverticula in 11–12. Hearts in segments 6–11, nephridial bladders sausage-shaped with a small ectal loop.

Remarks. Dendrobaena popi is close to the unpigmented D. misirlioglui but differs clearly by the number of vesicles ( Table 3 ).
