ABSTRACT
The weevil tribe Dryophthorini is reported in Peru for the first time. Two species from Satipo, Junin, Stenommatus chabooae Legalov n. sp. and Stenommatus sokolovi Legalov n. sp., are herein described. Stenommatus chabooae Legalov n. sp. is characterized by having the elytral interstriae narrower than striae width; pronotum coarsely punctate; large, narrow aedeagus, weakly curved at apex, with a large basal sclerite of the endophallus. Stenommatus sokolovi is characterized by having the elytral interstriae as wide as striae width; pronotum finely punctate; small, wide aedeagus, rounded at apex and endophallus lacking sclerites. A key to the South American species of the genus Stenommatus is given.
RESUMEN
Se reporta por primera vez la tribu Dryophthorini para Perú. Se describen dos especies de Satipo, Junín, Stenommatus chabooae Legalov n. sp. y Stenommatus sokolovi Legalov n. sp. Stenommatus chabooae Legalov n. sp. se caracteriza por poseer las interestrías elitrales más anchas que el ancho de las estrías; pronoto fuertemente punteado; aedeago grande, estrecho, ligeramente curvado en el ápice y con un esclerito basal grande en el endófalo. Stenommatus sokolovi n. sp. se caracteriza por poseer las interestrías elitrales tan anchas como el ancho de las estrías; pronoto finamente punteado y aedeago pequeño, ancho, redondeado en su ápice y endofalo sin escleritos. Se propone una clave para las especies sudamericanas del género Stenommatus.
