Distribution. As in original description.

Description. Flesh coloured or pinkish and transparent. Size 60-93 mm by up to 2.7 mm with 110-173 segments Setae small and closely paired (ab=cd). Clitellum 10-13. Spermathecal pores 7/8 projecting between b and c. Male pore on penes protruded or concealed in 10/ 11 in mid-bc. Female pores paired on 12 near 11/12 b lines. Genital papillae absent, only one specimen of fifteen had a marking in 8rhs.

Pharyngeal glands in 3-5. Septa 5/6-8/9 thickened. Hearts 6-9; dorsal blood vessel single. Spermathecal ampulla with convoluted duct that exits to atrium in 7/8 with 1 accessory gland in 8. Testis sacs spherical on 10/11 (9/ 10?) with vas deferens coiled and entering apex of male atrium. Ovarian chamber in 10/11/12 with eggsacs said to be “ slender and short ” but shown to extend from 12- 116 ( Ohfuchi, 1938: fig. 7.2). Gizzards generally four in 13-19 (but shown by Ohfuchi, 1938: figs. 6.3 and 7.2 in just 13-16). Nephridia absent from first five segments and last two or three.

Remarks. Kobayashi (1940: 311) footnoted that D. tairaensis seems synonymous with Drawida anchingiana Chen, 1933 . Ohfuchi (1938: 43) indeed said his species was similar to D. gisti anchingiana Chen but was distinguished as it lacked the accessory glands of the male atrium and spermathecal atrium, this despite his showing such a gland near the spermatheca for at least one Honjo specimen ( Ohfuchi, 1938: fig. 9.1). The four gizzards were confused (as with the previous species) as he gave them ( Ohfuchi, 1938: 42, 43) in 13-19 but showed them in 13-16 ( Ohfuchi, 1938: fig. 6.3 and 7.2), the latter being more likely. It has not been found subsequently.
