Differential diagnosis
Onitis crassus is closer to O. castaneus in having hairy pygidium and uninterrupted clypeo-frontal carina but differs from the latter in having short scanty setae on the pygidium; frontal tubercle being placed behind the carina while in O. castaneus it is placed on the carina and the anterior margin of clypeus being gently excised in the middle while in the latter it is reflexed and straight. See diagnosis of O. brahma .
