Diagnosis. Body pale testaceous, superior part of face and frontal rostrum dark brown, lateral lobes of pronotum dark brown with yellowish inferior part, lateral field of tegmen with dark band. Vertex convex and eyes vertically lengthened, 5th joint of maxillary palpi triangular. Tympana on both sides of fore tibiae and the inner one larger than outer one. Male genitalia with lateral processes slightly incurved ( Figs. 10–11 ).

Measurements. (in mm) Body 35.5, Ƥ5.8; body with wing 310.0–11.0, Ƥ10.0–12.0; pronotum 31.0, Ƥ1.0; tegmen 34.7–5.0, Ƥ5.0; posterior femur 35.0–5.5, Ƥ5.0–5.7; ovipositor 2.7–2.9.

Distribution. China (Yunnan, Hainan, Zhejiang); Burma; Malaysia; Indonesia; India; Sri Lanka. Remarks. Amusurgus fulvus has been confused with Amusurgus oedemeroides ( Walker, 1871) , but according to original description of the former species is characterized by body on the head behind the eyes to lateral field of tegmen with a dark brown band. We here reinstate the name as we believe it represents a distinct species. In addition, A. lateralis Chopard, 1969 is a pure synonym of A. fulvus judging from its description and illustration.
