Type of the genus. — Coccidoctonus trinidadensis Crawford. 



In Doctor Ashmead's classification this genus goes to Zaomma, from 

 which it differs in the long antennas, in the joints of the funicle being 

 elongate, in the less enlarged club which is not as long as the funicle 

 and in the prominent ovipositor.
