Bagous parvus

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 : 37

6. Bagous parvus group

Diagnosis. Body very small, less (char. 1.1) or at most just longer than 2.0 mm. Penis body at least 4 times longer than wide (char. 57.0).

Remarks. The three species that we refer to this group were previously placed in the B. pygmaeus group (Askevold et al. 1994; O’Brien et al. 1994; O’Brien & Askevold 1995), but are now referred to the genus Azollaebagous . The differences from this genus are the strongly developed postocular lobes, the more pronounced prosteral canal, the more elongate elytra with less marked posterior declivity, and lack of curved whitish band at apical third of elytra. This group is weakly supported in BI (75% pp).

Species included. ORR: *¹ B. joyi O'Brien, 1995 , *² B. parvus O'Brien, 1995 . PAL: *³ B. minor O'Brien & Morimoto, 1995 .
