Diagnosis. Macrobathra petalitis differs from its congeners in the frons with a longitudinal white line laterally; in the male genitalia by the right valva broadened towards apex and having a sclerotized denticle on the inner margin ( Fig. 24 ); in the female genitalia by the ductus bursae with posterior 2/5 tubular and sclerotized, and its left side narrowly extended from posterior 2/5 to about 3/5 like a spear ( Fig. 38 ).

Description. Adult ( Fig. 7 ). Wingspan 8.5–10.0 mm.

Female genitalia ( Fig. 38 ). Apophyses posteriores 1.5 times as long as apophyses anteriores. Seventh sternite widely banded posteriorly, with numerous short bristles. Sterigma corniform. Ductus bursae slightly longer than apophyses posteriores, basal 2/5 tubular and strongly sclerotized, left side narrowly extended from 2/5 to 3/ 5 in spear-shape, distal 2/5 membranous, with granules; accessory bursae arising from the posterior 2/5 of ductus bursae, spermatheca elliptical. Corpus bursae rounded, as long as posterior apophyses, granulous; two signa each being a small elliptical basal plate with a denticle, sunken.

Distribution. China (Fujian, Guangxi, Hainan, Hunan, Jiangxi), India.

Note. This species is newly recorded for China, and its female is described for the first time.
