Abdominal sternite VIII with posterior margin setose and broadly concave; anterior margin produced medially into a large quadrate process. Apophyses anteriores shorter than apophyses posteriores, with a small furcation near base. Ductus bursae wrinkled, broadly sac-like at base, broadened from below antrum to before middle, with some denticles on inner wall from anterior 1/4 to middle; ductus seminalis slender, strongly helical, arising from basal 1/3 of ductus bursae. Corpus bursae elliptical, about 2/3 length of corpus bursae; signum small elliptical, densely protuberant, with a longitudinal median furrow, at posterior to middle of corpus bursae. Diagnosis. This species is similar to D. causidica ( Meyrick, 1910 ) in the male genitalia, but it can be distinguished by the median process of the gnathos gradually narrowed from broad base to pointed apex and the outer margin of the cucullus arched ( Fig. 14 ); in D. causidica , the median process of the gnathos is sharply narrowed beyond middle, and the outer margin of the cucullus is obliquely straight. This species is superficially similar to D. similihoristis sp. nov. The differences between them are stated in the latter species. Distribution. China ( Yunnan ), India . Notes. This species is newly recorded in China and its female is described for the first time.
