Bagous cyperorum

ROBERTO CALDARA, CHARLES W. O’BRIEN & MASSIMO MEREGALLI, 2017, A phylogenetic analysis of the aquatic weevil tribe Bagoini (Coleoptera: Curculionidae) based on morphological characters of adults, Zootaxa 4287 (1), pp. 1-63 : 40

3. Bagous cyperorum group

Diagnosis. Integument completely hidden by finely pitted, almost smooth (char. 3.1) whitish scales, which on elytral intervals are polygonal and arranged in double rows (char. 41.1). Area over eye tuberculate. Rostrum in cross section cylindrical and equal in length in both sexes (char. 5.0). Tarsomere 3 subcordate, not wider than tarsomere 2.

Remarks. This monospecific group differs from all other Bagoini by the features of the elytral vestiture; within the subgenus Parabagous it is characterised by the larger size, the sexually monomorphic rostrum, and the different shape of the tarsi. In all analyses this group was sister to the other species of Parabagous , with generally strong support.
