Four new species of Trigonopterus Fauvel from the Island of New Britain (Coleoptera, Curculionidae)

Abstract

The hyperdiverse genus Trigonopterus has its center of diversity in Melanesia, but only a single species is recorded from the Bismarck Archipelago to date. Here we describe four new species from the island of New Britain: T. chewbacca sp. n., T. obsidianus sp. n., T. puncticollis sp. n. and T. silaliensis sp. n. We provide cytochrome oxidase subunit I (cox1) sequences of the new species and a key to all five species known from the Bismarck Archipelago.
