urn:lsid:zoobank.org:act:66B597D1-E741-42AC-A86E-5654078DB5D5

Type species

Luperodes tuberculatus Blake, 1942 , by present designation.

Diagnosis

In this genus, the anterior margin of the pronotum is fringed by a row of short setae, the basal margin of the pronotum is equipped with a fine bead, and the second abdominal ventrite of the male is equipped with two short horns ( Fig. 201 ). See the following key for additional diagnostic characters.

Etymology

The name ‘ Cornuventer ’ is Latin for ‘horn belly’, and it refers to the abdominal appendages of the male. It should be treated as a male noun.

Remarks

The single species included in this genus is C. tuberculatus (Blake, 1942) comb. nov. It was originally named in Luperodes and most recently placed in Pseudoluperus from California. See Fig. 122 for a habitus photograph.
