Copelatus Erichson, 1832
Remark.
Twenty-five species of Copelatus are currently known from Madagascar. All species except those in the erichsonii group were recently revised by Ranarilalatiana et al. (in press). The three species described below all belong to the erichsonii species group with ten discal and one submarginal elytral striae. Type materials of all erichsonii group species described from Madagascar have been examined in the ongoing second part of the revision.
