Diagnosis. This species can be separated from its congeners by the forewing has bigger and separated discal spots, the uncus is quadrate, postero-lateral lobe of the transtilla is short, fingerlike, forming an obtuse angle of about 120°, lateral lobe of the juxta is short, bean-shaped, and the phallus has dense fascicle-shaped microtrichia and crimples, and a sclerotized sword-like structure bearing dense spinules in the male genitalia ( Fig. 22 ), and the sub-rounded corpus bursae has a round, invaginated cup-shaped signum situated at middle in the female genitalia. It is quite similar to the new species D. similiquadrangula Ren & Li , sp. nov., but differs as noted in the description of the latter.

Eighth segment broad and short. Antrum sub-rectangular. Ductus bursae membranous, less than half length of corpus bursae. Corpus bursae membranous, sub-rounded, 1.4 times as long as maximum width, granulated on inner wall; signum round, invaginated cup consisting of concentrically arranged granules, situated at middle of corpus bursae. Ductus seminalis from corpus bursae near ductus bursae.
