Abstract

Camptopeltesn.gen. is described for three new species: Camptopeltes atratumn. sp. (type species of the genus; type locality Cartago, Costa Rica); Camptopeltes citrinumn. sp. (type locality Yacambo, Venezuela); and Camptopeltes nubilatumn. sp. (type locality Aragua, Venezuela). Camptopeltes is distinguished from other oscinelline genera on the combination of a strongly convex scutum, a trapezoidal scutellum that is deflected dorsally relative to the scutum, a reduced flexure in wing vein CuA1, reduced cephalic bristling, reniform third antennal segment, and thin arista. Although its relationship to the rest of the Oscinellinae is unresolved, it may be closely related to the tribe Elachipterini.

Résumé

Nous décrivons Camptopeltesn. gen. qui contient trois nouvelles espèces, Camptopeltes atratumn. sp. (espèce type du genre; localité type, Cartago, Costa Rica), Camptopeltes citrinumn. sp. (localité type, Yacambo, Venezuela) et Camptopeltes nubilatumn. sp. (localité type, Aragua, Venezuela). Camptopeltes se distingue des autres genres d'oscellinés par la combinaison d'un scutum fortement convexe, d'un scutellum trapézoïde retourné vers le bas relativement au scutum, d'une courbure réduite de la nervure CuA1 de l'aile, d'une réduction des soies de la tête, d'un troisième segment antennaire réniforme et d'une arista mince. Bien que la relation entre le nouveau genre et le reste des Oscinellinae ne soit pas élucidée, il se peut qu’il soit apparenté à la tribu des Elachipterini.
