Remark.

The reason to reduce the status of Hoplisoides distinguendus to rank of subspecies of Hoplisoides gazagnairei was, most likely, a similar form of males clypeus (apical part of the clypeus concave). The modified clypeus is not unique for these two taxa: clypeus with separated apical part present in the North American Hoplisoides hamatus (Handlirsch, 1888), H. nebulosus (Packard, 1867), H. placidus (F. Smith, 1856) and H. punctifrons (Cameron, 1890) (Buck, 2007). Besides, H. gazagnairei and H. distinguendus have many significant differences (besides coloration), given in the Table 1 .

Based on the above differences and the huge geographical hiatus, we consider Hoplisoides gazagnairei (Handlirsch, 1893) and H. distinguendus (Yasumatsu, 1939) as different species.
