( Figs 3 , 18–20 , 41 )

Neochauliodes jiangxiensis Yang & Yang, 1992 . Entomol. J. East China 1: 1. Type locality: Jiangxi (Yudu).

Diagnosis. Head dark; wing grayish brown with several small hyaline areas; lobes of male tenth tergum asymmetrical.

Male. Body length 16 mm; forewing length 31 mm, hindwing length 27 mm.

Head dark. Compound eyes brown, ocelli pale yellow with black inner margin. Antenna blackish brown. Mouthparts pale yellow.

Prothorax pale yellow; meso– and metathorax brown, dorsally with each centre yellowish brown. Legs pale brown with short, dense, pale yellow setae; tarsal claws pale red. Wings ( Fig. 3 ) grayish brown with several small hyaline areas on proximal 1/3 and distal 1/3; pterostigma long, pale yellow; costal area respectively with a brown stripe proximal and distal to pterostigma. Forewing costal cellule pale, except for large brown marks 1/3 proximally and 1/3 distally. Hindwing similarly marked, but with proximal half entirely hyaline and a wide hyaline transverse area 1/3 distally; costal area brown throughout. Veins pale brown. Rs four– branched, R 2 distally three–branched, three crossveins between R 1 and Rs; M two–branched; 1A two– branched.

Abdomen brown. Tenth tergum short, lobes asymmetric; left one ( Fig. 18 ) distally with three different sized digitiform processes, right one ( Fig. 19 ) simple with a small digitiform process on ventral membrane between ninth and tenth tergum. Tenth sternum ( Fig. 20 ) strongly sclerotized, flattened and slightly curved dorsad; in ventral view slender, suboblong, with proximal margin arcuately incised, distal margin truncate.

Type material. Holotype ♂, CHINA: Jiangxi, Qilushan , 5.V.1978, C. Yang ( CAU).
