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.

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.
