DIAGNOSIS OF FEMALE. Female of B. lineata ( Fig. 11 ) is very similar externally to male ( Fig. 10 ), but has more elongated forewing apex and filiform antennae. The female genitalia of B. lineata ( Fig. 24 ) are similar to those of B.

nubifascia ( Fig. 25 ) due very broad sclerotized lateral lobes of corpus bursae, but differ clearly by the much broader antevaginal plate with broader and deeper concavity, the much shorter ductus bursae with much broader lateral folds strongly broadened anteriorly, and the much broader anterior section of corpus bursae.

DESCRIPTION OF FEMALE GENITALIA ( Fig. 24 ). Ovipositor short, broad,

conical; papillae anales broad, rectangular with rounded edges; apophyses and posteriores long and thin, apophyses posteriores about two times longer than apophyses anteriores. Antevaginal plate wrinkly sclerotized, with round concavity near its conjunction with ostium bursae. Ostium bursae broad; ductus bursae broad, short,

dorso-ventrally flattened, with strongly sclerotized lateral trigonal folds, left fold much broader anteriorly than right fold. Corpus bursae broad, subdivided into two large asymmetric heavily sclerotized lateral lobes covered inside with numerous short spinules, and broad, sack-like, weakly sclerotized anterior section with weak spine-like scobination; appendix bursae small, conical, membranous, situated dorso-posteriorly.

DISTRIBUTION. China: Hunan, Sichuan (Fang 1993; 2000), Guandong (Volynkin et al., 2017); North Vietnam (Hoang Lien Son mountain range).
