The group comprises 11 species, of which 4 are redescribed and 3 are described as new ( (C. minor, C. siamensis, C. biloba). The remaining 4 species are endemic to the Philippines and are not redescribed. A key to the males, distribution maps, a phylogenetic reconstruction and a historical biogeographic hypothesis are presented.
