Bagous affaber

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 : 41

1. Bagous affaber group

Diagnosis. Ventral punctures distinctly large, excavate (char. 43.1). Orificial lateral sclerites with basal margin distinct. Sclerite complex within tube of penis body with pair of submedian, subapical well-separated sclerites (char. 84.1). Dorsal surface at base truncate (char. 64.1). Penis body subbasally notched in lateral view (char. 69.1).

Remarks. This group was strongly supported in all analyses. It has four synapomorphies (char. 43.1, 64.1, 69.1, 84.1), three of which are on the male genitalia. This group is represented by two Palaearctic species (both occurring also on the Indian subcontinent) and one Indian species.

Species included. ORR: *² B. frontalis O'Brien, 1995 ; ORR & PAL: *¹ Bagous affaber Faust, 1887 , ¹ B. latepunctatus Pic, 1904 .
