Measurement. Length male 4.20–4.30mm.

Material examined. Holotype: ♂, China, Yunnan Prov., Lancang, Munai, 1100m, bamboo, 2 xii 1999, coll. I. Dworakowska. Paratypes: 1♂, China, Yunnan Prov., Lancang, 1100m, 2 xii 1999, coll. Qin Daozheng; 1♂, China, Yunnan Prov., Mengyuan, Sanchahe, 950m, 20 xii 1999, coll. I. Dworakowska.

Deposition. Entomological Museum, NWAFU, Yangling, China.

Remarks. The new species resembles C. bischofiae Sohi , but the pygofer dorsal appendage is absent, the style is slender, the aedeagal shaft has the basal part parallel-sided and the apical part exaggeratedly sinuate.

Etymology. The specific name is derived from the Latin word “ sinuatus ”, referring to the sinuate aedeagus.
