Description. Head (Fig.10) black, with dark ochraceous longitudinal fascia medially in dorsal view, postclypeus longer than vertex in dorsal view; compound eye brown; ocellus red. Distance between lateral ocellus and corresponding eye slightly shorter than distance between lateral ocelli. Base of antenna black, and brown apically. Rostrum black, extending to apex of mid coax.

Pronotum (Fig.10) black, shorter than head and mesonotum, with dark ochraceous median longitudinal fascia in dorsal view. Mesonotum (Fig.10) with submedian sigilla and lateral sigilla black.

Fore wing (Fig.10) hyaline in apical half, basal half brown and translucent; irregular reddish wide fasciae along node line, anterior margin of fore wing, basal part of fore wing and clavus, forming a triangular frame. Hind wing (Fig.10) hyaline, veins of basal two thirds red and light brown apically. Basal membrane of fore wing and base of hind wing red.

Abdomen (Fig.10) cylindrical, black, with dark ochraceous median longitudinal fasciae; terga VI–VII with white tuft of hairs laterally in dorsal view. Timbal cover small, timbal largely exposed. Male operculum short and falcate.

Male genitalia. Dorsal beak of pygofer in lateral view slender, protruding upwards; upper lobe of pygofer in lateral view long and curved inwards. Clasper in ventral view short, with lateral clasper lobe roundly broadened. Aedeagus with six long spine-like processes apically and subapically. Posterior margin of sternite VII angularly protruded; posterior margin of sternite VIII with ‘V’-shaped incision medially.

Female with ovipositor sheath extending to apex of abdomen; posterior margin of sternite VII with median ‘U’-shaped incision.

Measurements (in mm). Body length: 17.0–19.0; expanse of fore wing: 42.0–48.0 (According to the measurments of the holotype of Distant, 1892).

Material examined. No specimen available.

Biology. Unknown.

Distribution. China (Tibet), Nepal, India, Sri Lanka, Bangladesh.

Remarks. There was a specimen of this species deposited in NWAFU (Chou et al., 1997), but a search for it was unsuccessful. The species is redescribed above according to the photos of the type specimens deposited in BMNH and the description of Hayashi (1978) and Chou et al. (1997).
