22. Drawida jeombongsan Blakemore sp. nov.

Material. Holotype IV0000261314 (DNA sample HY10), mature specimen, from Jeombongsan Mt., between the counties of Inje and Yangyang, Gangwon-do in South Korea (38 01′16.39′′ N 128 25′6.36′′ E), collector Dr H- Y Seo 25 th July, 2013. Sample also contains two tail portions, one possibly belonging to this specimen, a mature Metaphire hilgendorfi ( Michaelsen, 1892) ( NIBR 261310) and several Amynthas sp. (IV0000261311-3, IV0000261 315-22). Same location and collector, 11 th July, 2013 an Amynthas sp. ( IV 0000261308) and a mature blue Drawida sp. (possible same, IV 0000261309).

Etymology. After the type locality, noun in apposition.

Description. Light blue colour. Prostomium proepilobous, peristomium smooth. Length 60+ mm (posterior amputee). Segments 125+. Clitellum unclear. Dorsal pores absent. Nephropores in cd lines in some segments. Setae small and closely paired. Spermathecal pores superficial in 7/8 near ab-lines. Male pores superficial on 10/11 ab-lines. Genital markings equatorial paired discs in bc on 7, unilateral in ab on 8lhs, and paired in ab in 11 (encompassing ventral setal couples) and 12, the latter slightly more posterior and within common lateral field that tapers to c setae. Female pores paired slits above ab-lines in 12.

No atrium nor glands found near spermathecal pores, spermathecae attach to 7/8. Vasa deferentia go to body wall from testis sacs in 9/10, prostates as small sessile glands, no penes present. Gizzards are in 13-16 (four of). Nephridial bladders are elongate.

Remarks. Distinctive characters from its nearest neighbour are the genital markings more ventral than in D. odaesan and four gizzards (in 13-16) rather than five (in 13-17) as in D. odaesan . The superficial, closely aligned spermathecal and male pores plus four gizzards (but in 14-17) are reminiscent of D. songae yeongdo Blakemore, 2013 accorded similarity of only 88% from DNA data (in Appendix, Fig. 1) that objectively separate these three taxa along with several other physical characters.
