Description.

Colour and external characters as in generic description.

Male genitalia as in generic description with aedeagal shaft distally digitate, with pair of elongate subapical processes, sharply curved dorsally and converging apically, robust basally and strongly tapered distally to sharply pointed apex, shaft without process on dorsal surface (Figs 7 , 9 ).

Female genitalia as in generic description with seventh sternite tapered distally with posterior margin triangularly produced laterally (Fig. 16 ).

Measurement (mm). Length (including tegmen): ♂, 4.39; ♀, 4.67–4.91.

Type material.

China: • 1 ♂ ( holotype), Xizang Autonomous Region, Linzhi City, Bayi ; 10 August 2017, coll. Zaihua Yang ( GUGC) . Paratypes: • 4 ♀♀, same data as holotype; ( GUGC) ; • 1 ♂, Xizang Autonomous Region, Linzhi City, Bayi ; 3 July 2012, coll. Maofa Yang ( GUGC) .

Distribution.

China: Xizang.

Remarks.

This new species can be distinguished from the male of the latter species by the aedeagal shaft without a process on the dorsal surface and the apex of the aedeagal shaft with a pair of long dorsally curved processes.

Etymology.

The species name is derived from the Latin word “ curvatus ”, referring to the strongly curved aedeagal processes.
