Species included in Cholovocera , which we regard as belonging to other genera

Besides the eight species belonging to the genus Cholovocera described above, there are six other beetle species that have either been described in this genus or transferred to it, but which we do not consider to be members of Cholovocera . In our opinion, the morphological characters of these six species do not fit our definition of Cholovocera , and some of them occur in regions far outside the geographic range of this genus.
