The mature oocyte, all five larval instars, and the pupa of Ctenoplectra cornuta Gribodo are described based upon specimens from Taiwan. Its mature larva though larger is compared with, and found similar to, that of the African Ctenoplectra armata Magretti, the only other larval ctenoplectrine studied to date. The egg index was similar to that of the African C. albolimbata Magretti. Although Ctenoplectra shares certain larval and pupal similarities with Tetrapedia (Tetrapediini), a broader study including representatives of all apine tribes needs to be considered for evaluating tribal relationships.
