Bagous brevis

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 : 48

25. Bagous brevis group

Diagnosis. Tarsi sublinear, short; tarsomere 3 as wide as tarsomere 2. Penis body widest at level of dorsal process and constricted behind dorsal process (excluding B. lutulosus ), with apex subtruncate, very bluntly rounded; dorsal process low, flattened, laterally with pair of short wings obliquely arranged (char. 101.1), with setal brush situated anteromedially (excluding B. lutulosus ); with costate lateral margin behind dorsal process; ventrally bicarinate from base to below orifice.

Remarks. This Palaearctic group is characterized by the shape of the dorsal process, which is flattened and with pair of lateral wings (char. 101.1). In our analyses it was supported in BI (75% pp) and ML (60% bs). It was recovered as a group, but not supported in MP (44% sr).
