Eisenia nordenskioldi nordenskioldi ( Eisen, 1879)

Allolobophora nordenskioldi Eisen, 1879: 6 .

Eisenia nordenskioldi nordenskioldi : Perel 1997: 69.

Eisenia nordenskioldi nordenskioldi : Blakemore 2013b: 2.

Notes: To compare with the Korean E. nordenskioldi material we have obtained several specimens from Siberia ( Russia) belonging to the nominal subspecies.

Material examined: Russia, South Siberia, Tyumen, 18.07.2013, 4 ex. Leg. V. Chernov.

Remarks: All the four specimens are dark red especially on dorsum, with paler spots on both side around 9-11 cd. Setae closely paired, size of the single complete specimen 100 × 7 mm, segment No. 143. Clitellum 27-½33, tubercles 29-31. Genital papillae around setae ab on segments 8, 27-31. ( Table 2). Four pairs of vesicles in 9-12, the first two pairs in 9-10 are somewhat smaller than the last two. Spermathecae in 9/10-10/11 elongated, irregular sac-shaped open near to the dorsal pores. Typhlosole small, tubular protuberance of the intestine.

E. n. nordenskioldi clearly differs from E. n. pallida apart from the pigmentation also in the distribution of genital the papillae, the shape of the typhlosole and setal arrangement ( Fig. 10 ). However the real differences among the closely related dark-red pigmented species in the E.

nordenskioldi species group need still to be worked out ( Table 4).
