Distribution. As in original description.

Description. Yellowish. Size 228-283 mm by up to 6.5 mm with 189-242 segments Setae small and closely pair- ed (ab=cd). Nephropores minute, lateral. Clitellum 10-

13. Spermathecal pores 7/8 eye-shaped ventral of c-lines. Male pore in 10/11 approximately in b-lines in transverse slits; primary pores on small disc-shaped penes. Female pores paired in 11/12 approximately in ab lines. Genital papillae variously paired in 7-13 with glands internally.

Pharyngeal glands in 3-4. Hearts 6-9; dorsal blood vessel single. Spermathecal ampulla with convoluted duct that exits to body wall without atrium nor accessory gland in 7/8. Testis sacs spherical on posterior of 10/11 (9/10?) with vasa deferentia coiled and entering body wall under roundish prostates. Ovarian chamber in 11 with short ovisacs from fused 11/12. Gizzards usually four in 12-17, sometimes 12-18. Nephridia with hairpin vesicles, vestigial in 10 and 11.

Remarks. Ohfuchi (1938) distinguished his species from Kobayashi’s D. nemora on the basis of position of gizzards, body length, structures of the penis and prostates. However, the four gizzards are confused since Ohfuchi (1958: 38 vs. fig. 4.1) has them in 12-17 or sometimes in 12-18 but shows them in 12-15 which is more likely the conventional location and the same as in D. nemora! It too was not found subsequently. Kobayashi (1940: 311) thought D. ofunatoensis synonymous with D. nemora Kobayashi, 1936 but it is somewhat larger, average 251 mm in length, and the GMs although relatively regular are not shown mid-ventrally as in D. nemora .
