Holotype. HNHM/16810 1 ex., Ţarcu Mts , after Măru, beech forest, 501 m, N 45°25.978’ E 22°27.550’, leg. Cs. Csuzdi, J. Kontschán, V. V. Pop, 02.11.2007.

Paratypes. NHMV/4990 2 ex., Mehadia, leg. L. Ganglbauer.

Etymology. The name refers to the special colour of the specimens (‘cinerea’ = greyish).

Diagnosis. Length 113–132 mm, diameter 5–6 mm, setae distantly stand- ing. Pigmentation grey with slight reddish hints. First dorsal pore in 8/9. Cli- tellum on 25–30, tubercles on ½ 25–½ 29. Male pores hardly seen on segment 15. Nephridial pores aligned above setal line b. Four pairs of seminal vesicles in 9–12; spermathecae 9/10, 10/ 11 in setal line d. Calciferous glands with welldeveloped diverticula in 11. Hearts in segments 7–11, nephridial bladders biscuit-shaped.

External characters. Holotype 132 mm long and 6 mm wide. Number of segments 134. Paratypes 113–121 mm long and 5–5.5 mm wide. Number of segments 153–157. Pig- mentation grey with slight reddish hints. Prostomium epilobous ½ closed. First dorsal pore at the intersegmental furrow 8/9. Setae distantly standing. Setal arrangement behind clitellum: aa:ab:bc:cd:dd = 1.57:1.29:1.19:1:1.95. Male pores hardly seen on segment 15. Ne- phridial pores just above setal line b. Clitellum on segments 25–30. Tubercula pubertatis on segments ½ 25–½ 29. Glandular tumescence on segments 10, 11, 13, 14, 26, 29, 30 ab.

Internal characters. Septa 6/7–7/8 and 11/12 slightly thickened, 8/9–10/11 thickened, 12/13–14/15 strongly thickened. Testes and funnels paired in segments 10–11, covered by perioesophageal testis sac in segment 10–11. Four pairs of seminal vesicles in 9–12. Two pairs of spermathecae in 9/10, 10/11 with external openings in setal line d. Calciferous glands with well-developed diverticula in segment 11. Paired hearts in segments 7–11. with a pair of small extraoesophageal vessels in 12. Nephridial bladders biscuit-shaped.

Crop in segments 15–16, and gizzard in segments 17–18. Typhlosolis unilobous. The crosssection of the longitudinal muscle layer of pinnate type.

Remarks. According to the phylogenetic reconstruction based on the ITS2 sequences, the new species is placed into the clade of species bearing redviolet or greyish pigmentation and calciferous diverticula in segment 11 ( Fig. 2). Dendrobaena sp. n. stands most closely to D. herculis Szederjesi, Pop et Csu- zdi, 2017 and D. annectens ( Rosa, 1895) . Morphologically it most resembles D. depressa (Rosa, 1893) and D. carpathomontana ( Szederjesi, Pop et Csuzdi, 2017) with its size and the clitellar organs, but differs from them in the position of the male pore and colouration. The most important morphological character- istics of the similar species are shown in Table 3.
