Bagous josephi

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 : 35

1. Bagous josephi group

Diagnosis. Prosternal canal weak (char. 31.1). Sclerotization of ventral surface of penis body broadly membranous. Sclerotized area of dorsal surface of penis body greatly reduced and present only as a narrow basal bridge (char. 63.1). Endophallus lacking sclerites.

Remarks. Monospecific. Some characters of the penis, such as the almost completely membranous dorsal surface of the body and the complete absence of sclerites in the endophallus, are uncommon in the Bagoini. Species included. AUS: * Bagous josephi O'Brien, 1992 .
