Renefouqueosis gen. nov.

Type species. Renefouqueosis peruviensis sp. nov. by present designation.

Composition. The genus includes only the type species, Renfouqueosis peruviensis sp. nov.

Description. Body relatively small (around 3 mm). Head without dorsal keels, with antennomeres completely separated; eyes positioned above and anterior to an antero-lateral extended genal keel, composed of an elongate series of facets. Pronotum widest at anterior third, 1.125 times wider than long, cordate, anterior margin concave, posterior margin truncate, with two keels. Scutellum small, triangular. Elytra with keels on intervals 3, 5 and 7.

Comparative diagnosis. Renefouqueosis gen. nov. ( Stenosini : Stenosina ) can be distinguished from all other genera of New World Stenosini (subtribe Stenosina ) by the following characters: (1) the antennomeres are completely separated ( Ecnomoderes Gebien, 1928 as well as Grammicus Waterhouse, 1845 , which also occurs in Southern Peru has the antennomere XI embedded in the X apically); (2) pronotum with coarsely serrate lateral margins and (3) the presence of two keels on the central aspect of the pronotum ( Caribanosis Nabozhenko et al., 2016 has a single keel centrally positioned on the pronotum while, Schizaraeus Kulzer, 1955 , lacks keels). In Old World Stenosini (subtribe Stenosina ), of the genera which have both pronotal and elytral keels, but not head keels, which includes Anethas Jakobson, 1924 , Gebieniella Koch, 1940 , Stenoethas Kaszab, 1975, and Tetranosis Medvedev, 1995 , all have the pronotum clearly longer than wide, sometimes much longer than wide. In Caribanosis the pronotum is slightly wider than long (1.05: 1.00). Ethas Pascoe, 1862 and Perdicus Fairmaire, 1899 have pronotal elevations but in these the elevations are rounded, not keeled. In Renefouqueosis gen. nov., the pronotum is clearly wider than long (ratio 1.125: 1.000). The wide pronotum with serrate margins and of the eye which is composed of an elongate series of facets positioned above an antero-lateral extended genal keel, rounded anteriorly, visible from above only at posterior, rest of eye facets, not separated by a furrow, facing anteriorly, not visible from above due to genal extension above antennal insertion and not visible from below due to lateral genal extension is also unique.
