The asexual and sexual generations are known for both species, developing in detachable leaf galls and catkin galls, respectively. Morphologically, the genus closely resembles Dryocosmus and Plagiotrochus ( Pujade-Villar et al . 2003b ; Melika et al . 2010 ), but its synonymization with Dryocosmus by Ács et al . (2007) was premature and did not incorporate adequately molecular or morphological characters found in other cynipid genera (e.g., Aphelonyx , and Neuroterus ). In a more recent phylogenetic reconstruction, C. nitida and C . israeli formed a strongly-supported monophyletic clade together with Plagiotrochus , and were clearly separated from Dryocosmus ( Stone et al . 2009 ) .
