Material examined
1♂ (NWAF), China: Guangxi Prov., Ningming, 19-V-1984, coll. Wang Jijian; 1♀ (NWAF), China: Guangxi Prov., Longzhou, 17-V-1983, coll. Liu Sikong.
Description
Head (Fig. 7A–D) mostly reddish brown, symmetrically with small black stripes on vertex; clypeus reddish brown and depressed; ocellous reddish, eye castaneous, distance between lateral ocellus and corresponding eye as long as distance between lateral ocelli; gena and lorum mostly reddish brown, with tuft of golden hairs and lorum symmetrically with pair of black stipes; rostrum reddish with apical half dark brown, extending to apex of mid coxae.
Pronotum (Fig. 7C) reddish brown, with paramedian and lateral fissures ochreous. Mesonotum (Fig. 7C) mostly reddish brown, centrally with pair of short and slightly outwardly curved obconical black fasciae, reaching to about the 1/4 of mesonotum; pair of slender short black stripes and irregular markings lateral to the outwardly curved fasciae; cruciform elevation reddish brown. Ventral surface of thorax mostly reddish brown.
Legs (Fig. 7G) mostly reddish brown; tarsi and pretarsal claws dark reddish brown; fore femur with primary spine long, digitate and prostrate; secondary spine short, sharp and erect; subapical spine short, sharp and almost prostrate.
Wings (Fig. 7A–B) hyaline, veins generally in basal half reddish brown and brown apically; fore wing with continuous brown fascia along apical parts of apical cells 1–7 and associated outer margin; hind wing with two continuous brown fascia: one along apical parts of apical cells 1–5 and associated outer margin, the other along outer margin of vannal region.
Male abdomen (Fig. 7A–B) mostly black dorsally and reddish brown ventrally, with central trapezoid reddish brown mark on tergite II; timbal cover (Fig. 7F) reddish brown; operculum (Fig. 7E) reddish brown, extending slightly beyond posterior margin of abdominal sternite II, widest at half-length, medial margin of operculum slightly convex, posterior margin rounded, lateral margin weakly sinuate and gradually curved inwardly, medial margins nearly touching each other. Female abdomen mostly black dorsally and yellowish brown ventrally, with golden hairs on each posterior margin of terga 2–8; operculum small, triangular, with posterior margin truncated, extending not beyond posterior margin of abdominal sternite II, both opercula well separated from each other.
Male genitalia (Fig. 8A–D). Pygofer oval in ventral view; dorsal beak protruding upwards in lateral view; distal shoulder broadly rounded; upper lobe remarkably developed, forming a very large triangular-shaped protrusion in lateral view. Uncus with apex of median lobe slightly developed ventrally, forming a small process in both lateral and ventral views. Clasper in ventral view with median clasper process very long, broaden basally, apex strongly curved laterally, hook-like in shape; lateral clasper lobe roundly developed. Aedeagus in ventral view with three long apical processes curved dorsad and other three small to large lobe-like processes curved ventrad; the shortest lobe-like process with three short spines apically in ventral view; the medial lobe-like process bifurcate subapically, with apices acute; the third lobe-like process large, with apex somewhat rounded. Posterior margin of sternite VII short and rounded.
Female pygofer (Fig. 9A–B) with dorsal beak short and acute, shorter than protruding part of ovipositor; posterior margin of sternite VII with median incision large and broad, deep to about 4/5 the length of sternite VII.
Measurements (1♂, 1♀) (in mm). Body length: ♂ 28.0, ♀ 26.0; fore wing length: ♂ 31.0, ♀ 31.0; fore wing width: ♂ 11.5, ♀ 11.0; width of head including eyes: ♂ 9.5, ♀ 9.0; pronotum width (including pronotal collar): ♂ 10.0, ♀ 11.0; mesonotum width: ♂ 9.0, ♀ 10.0.
Biology
Unknown.
Distribution
China (Guangxi), Vietnam.
Remarks
This species is similar to Nipponosemia terminalis but can be distinguished from the latter by a larger body size, the wings with large brown markings, the pronotum without markings, and the mesonotum with only one pair of obconical marks, in addition to the differences in male genitalia (Chou et al. 1993[3], 1997[1]).
