Cephennodes bos species group

This species group is characterized by the peculiar modification of the antennomere III of males, which has a strikingly long subtriangular dorsal projection with its surface proximal to the base of antenna convex, whereas the opposite, distal surface is concave. The frons and vertex of males bear a median longitudinal line composed of fine and dense punctures. The aedeagus represents a slightly modified simonis form, with a large median lobe bearing two groups of short setae on the subapical dorsal area. Three identifiable species belong in this group, all known from Vietnam: C. bos Jałoszyński & Nomura, 2009 , C. buceros Jałoszyński & Nomura, 2009 and C. bubalus Jałoszyński & Nomura, 2009 . Additionally, Makhan (2005) described " Cephennodes ashnae " from China (Chongqing Province). This species clearly belongs to the Cephennodes bos group, but it was "described" in a way that excludes any chance of species identification, clearly with misinterpreted morphological structures, and the depository of the type material given by the author was apparently purposely wrong and misleading. Problems related to this species, actions taken to discover the true depository of the type material and reasons to treat this name as a nomen dubium were given in Jałoszyński (2007a).
