Heffern et al. (2020) recently synonymized Ochraethes nigritus and discussed the pubescence colour of the body in both species, which is not informative to separate them. The similar form of their frons, anteclypeus and labrum are other characters which support this proposed synonymy. The pubescence coloration in this species ranges from bright to dark tones, even totally dark.

Also, in this work, we propose O. clerinus as a junior synonym of O. viridiventris based on the same situation as O. nigritus . Bates (1892) described O. clerinus and O. nigritus from the same locality in Guerrero; these specimens are very similar and differ only in the coloration of pubescence on body. The holotype of O. clerinus is female, which is very important because females are commonly longer than males, and the holotype of O. viridiventris is a male (the specimen was described as female). The pattern of the black pubescence on the elytra is almost identical, the elytral apex obliquely truncate, anteclypeus and labrum have the same shape in the type material of the two species described by Bates ( Fig. 4J–L ).
