Cyrta tiantaishanensis sp. n. (Fig. 6)

Description. Body length: ɗ 7.5–7.7mm. Body generally black; vertex with brown laterally near eyes; gena, lora and anteclypeus with brown patches; anteclypeus with pair of stout setae apically; scutellem with short tufts of black setae basally near lateral margin (Figs 6 B, C).

Male pygofer with subgenital plate extending nearly to apex of pygofer side (Fig. 6 G). Aedeagal shaft evenly tapered to acute apex in lateral view, slightly expanded subapically and narrowly rounded in ventral view, with dense small tubercles on distal half laterally; gonopore apical (Figs 6 D, E).

Type material. Holotype. ɗ (NWAFU), CHINA: Shasnxi Prov., Feng Co., Tiantaishan, 2000m, 9-VI- 1998, Yang Linghuan. Paratype: 1ɗ (NWAFU), same data as holotype.

Etymology. Named after the type locality.

Remarks. This new species is similar to C. hirsuta Melichar, but can be distinguished from it by: 1) the black patch on vertex extending from posterior margin to anterior margin of vertex (Fig. 6 C); 2) lora bicoloured (black and brown) (Fig. 6 A); 3) aedeagal shaft evenly tapered to acute apex in lateral view, slightly expanded subapically and narrowly rounded in ventral view, with dense small tubercles on distal half laterally.
