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

摘要

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: Trigonopterus chewbacca >sp. n., Trigonopterus obsidianus >sp. n., Trigonopterus puncticollis >sp. n. and Trigonopterus 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.
