1. Subgenital plate with spine-like processes apically. Ovipositor with apical margin denticulated. From Malay Peninsula............................................................................................ C. lorniensis sp. n.

- Subgenital plate fairly simple, without spine-like process apically. Ovipositor with apical margin not denticulated. Not from Malay Peninsula...................................................................................... 2

2. Tenth abdominal tergite simple, mostly hidden. Epiproct hexagonal, laterally with obliquely upwardly projecting, rounded lobes. Pileolus rounded-triangular, nearly oval; narrow rounded apically, more strongly directed dorsally. Cercus more elongated. Subgenital plate angularly truncated apically. Ovipositor strongly bent dorsad in the middle; apex pointing dorso-vertically. From Borneo..................................................... C. securifera (Brunner von Wattenwyl)

- Tenth abdominal tergite elaborated; bent at an obtuse angle along arcuate edge ventro-posteriorly.
