Four new species of the genera Dryophthoroides Roelofs, 1879 and Nephius Pascoe, 1885 (Coleoptera, Curculionidae) from Oriental and Papuan Regions

Abstract

Four new species of the genera Dryophthoroides Roelofs, 1879 and Nephius Pascoe, 1885 from the tribe Stromboscerini of the subfamily Dryophthorinae are described and illustrated. Dryophthoroides telnovi Legalov, sp. nov. from New Guinea (Star Mountains) is similar to D. seftoni (Zimmermann, 1944) bit differs in the shorter and thicker rostrum and narrower pronotum. It is distinguish from D. beccarii (Pascoe, 1885) in the smaller body size, thicker rostrum, coarser punctured pronotum, not subparallel elytra and narrower elytral interstriae. Dryophthoroides insularis Legalov, sp. nov. from North Moluccas (Bacan Islands) differs from D. telnovi Legalov, sp. nov. in the wider, laterally weakly rounded pronotum with a more finely punctured pronotal disc, the stronger widened interstria five at apex, the smaller punctures in elytral striae, the wider elytral interstriae and the longer and thinner rostrum. Nephius continentalis Legalov, sp. nov. from Laos (Hua Phan Prov.) differs from N. kalimantanensis Legalov, 2022 in the thicker and shorter rostrum, the pronotum lacking the sharp preapical constriction, the elytra with the greatest width postmedium, the medially not depressed lateral sides of the pronotum, and the obsolete humeri. Nephius philippinensis Legalov, sp. nov. from the Philippines (Mindanao Is., Bukidnon Prov.) differs from N. mindanaoensis Legalov, 2020 in the sparsely punctate pronotum with a median longitudinal groove and lacking four premedian pilose ridges, the elytral interstriae with weak pilose ridges, and the less curved rostrum.
