Bagous subruber

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 : 43

9. Bagous subruber group

Diagnosis. Area over eye tuberculate. Tarsomeres short, nearly as long as wide and all of the same width. Sclerites complex within tube of penis body with two pairs of subapical sclerites, one submedian and the other sublateral and posteriorly joined (char. 84.3). Penis body laterally membranous and dorsally with two overlapping poorly sclerotized pairs of plates covering orifice (char. 67.1).

Remarks. Monophyly of this group is suggested by the uncommon shape of the body of the penis and the endophallic sclerites. Although the unique synapomorphies are in the features of the penis body, these species have a characteristic habitus (shape of pronotum, elytra and legs and elytral vestiture) which allows their easy recognition. The group is presently composed of five Palaearctic species.
