ZooKeys 467: Ninety-Eight New Species of Trigonopterus Weevils from Sundaland and the Lesser Sunda Islands

About this book

Trigonopterus is a little known genus of weevils, containing hundreds of species, the majority of them without a scientific name. This is the second part on this genus using a fast-lane approach of accelerated and improved taxonomy to describe its largely undocumented diversity. Based on focused field-work the fauna from Sundaland (Sumatra, Java, Bali, Palawan) and the Lesser Sunda Islands (Lombok, Sumbawa, Flores) is here revised. Previously, only one species was so far recorded from this area. Herein, an additional 98 new species are described.

We combine concise expert descriptions with DNA sequencing, digital imaging, and automated wiki species page creation from the journal. The concise descriptions providing a valid name can be gradually updated or modified in the fully versioned wiki-framework. A database of DNA sequences with an identification engine offers an alternative to a traditional identification key and helps to avoid synonyms. Most Trigonopterus species of Sundaland and the Lesser Sunda Islands belong to the litter fauna of primary wet evergreen forests. This habitat has become highly fragmented in the study area and many of its remnants harbor endemic species. Conservation measures should be intensified, especially in smaller and less famous sites to minimize the number of species threatened by extinction.
