Material examined: Russia, Dagestan, 05.07.1989, 45 ex. Leg. A. Zicsi, Cs. Csuzdi ( HNHM /11047), Dagestan, 09.07.1989, 42 ex. Leg. A. Zicsi, Cs. Csuzdi ( HNHM /11057), Dagestan, 10.07.1989, 11 ex. Leg. A. Zicsi, Cs. Csuzdi ( HNHM /11063).

Remarks: Our material completely agrees with that of Kvavadze (1985) from around Lagodechi. All the specimens were red violet alive however, in the preserved material most of the pigmentation bleached out. Setae moderately paired, biometry of the worms varies between 66- 115 × 3.5- 5 mm, segment No. 117-135. Clitellum 25, 26-34, tubercles ½28-½32, 32. Genital papillae around setae cd on 9-11, ab on segments 25-37, 38 ( Table 2). Four pairs of vesicles in 9-12, the first two pairs in 9-10 are smaller than the last two pairs. Spermathecae in 9/10-10/11 elongated sac-

shaped open near to the dorsal pores. Typhlosole large, T-shaped.

E. lagodechiensis is clearly close to E. nordenskioldi , however differs from it by the larger ab and cd setal intervals ( Fig. 11 ), the longer clitellum and its very special papillar arrangements. Apart from having papillae around 9-11 cd, it has large papillae far behind the clitellum which is a page 10 of 15

quite distinctive character. Therefore, we agree with Kvavadze (1985) and Perel (1997) that E. lagodechiensis is an independent species.
