Drawida gisti

Gates, 1935: 2
;
1939: 406
; 1940: 406;
Kobayashi, 1937: 333
, fig. 1; 1938: 85, fig. 2; 1940: 272; Blakemore & Kupriyanova, 2010: 16.
Distribution.
Central and northern
China
and central and northern
Korea
(from Kobayashi, 1935: 95; 1940) abundant in Keijo (
Seoul
) and its vicinity and from Kinsen.
Description.
Yellow grey, clitellum pinkish. Size
77-151 mm
by up to
6 mm
with 180-190 segments Prolobous. Setae small and closely paired (ab=cd). Dorsal pores absent. Clitellum
1
/
29,10
-13,14. Nephropores somewhat in line with c or more dorsal. Spermathecal pores 7/8 near to c-lines. Male pore in wide slits on blade-shaped penes in 10/11 b-c lines. Female pores paired on 12 near 11/
12 in
ab-lines. Genital papillae present, typically with a small pair, presetally on 10, or as larger discs in some of 7-12 with glands internally, or often absent.
Last hearts in 9. Spermathecal ampulla small with convoluted duct to ental end of large atrium in 7/8 with characteristic bulge, no accessory gland nearby. Testis sacs on 9/10 with coiled vas deferens entering ental end of large glandular prostate on penial pouch. Ovarian chamber in 10/11/12 with eggsacs extending to 13 or 14. Gizzards three in 12-14.
Remarks.
Its subspecies
D. gisti nanchangiana
Chen, 1933: 200
is from
China
, the other sub-species,
D. gisti anchingiana
Chen, 1933: 202
was elevated to specific status by
Kobayashi (1937: 333)
. Said by Gates (1940: 408) to be similar to
D. hehoensis
Stephenson, 1924
(from
Myanmar
) that was later associated with
D. barwelli
but differentiated on the greater size of the prostates and their relation to the penial pouches and the ‘urn-shaped’ spermathecal atrium plus GMs, when present.
D. cheni
Gates, 1935
was described by mistake by
Chen (1933)
as
D. gisti
f. typica
which introduced some confusion. Genbank’s DNA barcode data in the Appendix has no close match.
