Drawida keikeiensis : Kobayashi, 1941: 263; Easton, 1981: 39, tab. 1; Blakemore, 2003, 2010, 2014; Blakemore & Kupriyanova, 2010: tab. 3.

Distribution. Korea and Japan (from Kobayashi, 1941: 263) Honshu in Chubu-chiho, Kinki-chiho, Gugoku-chiho and on Shikoku and Kyushu also, i.e. widespread.

Description. Grey. Size 40-54 mm by up to 2.5 mm with 138-154 segments Prolobous. Setae small and closely paired (ab=cd). Dorsal pores absent. Clitellum begins to appear on 10-13. Nephropores in line with c. Spermathecal pores 7/8 nearer to c-lines. Male pore on blade-shap- ed penes in 10/11 a-c lines. Female pores paired in 11/ 12 in b-lines. Genital papillae absent.

Septa 5/6-8/9 thick; 10/11 and 11/12 combined in 11/ 12. Hearts last in 9. Spermathecal ampulla with convolut- ed duct to middle of atrium in 7/8 with accessory gland nearby. Testis sacs on 9/10 with very short vas deferens twisted and entering ental end of prostate. Prostate small, short but broad and warty on surface; medial to the prostate is large ovoid gland (not shown in Kobayashi’s fig. 4). Ovarian chamber in 10/11/12 with eggsacs extending to 16 or to 22. Gizzards three in one specimen in 13-15 and four in the other in 12-15. Nephridia vesiculate, vestigial in 9 and 11.

Remarks. Kobayashi (1938: 110) said his species was similar to D. syringa Chen, 1933 and also to D. cheni ( Gates, 1935) but differs from the former mainly in the shape of the penis and from the latter by many characters. Its occurrence in Japan has not since been confirmed although this may relate more to lack of study than true situation.
