The canopy dwelling weevils of the genus Cadoderus and allied genera demonstrate significant diversity in fragmented montane and gallery forests of East Africa. Adults have various cryptic coloration or vestiture to hide them among branches covered with lichens and moss. Cadoderus Marshall, 1926, Sphrigodellus Marshall, 1942, and Oncophyes Marshall...

Welcome to World catalogue of Entiminae weevils! Entiminae is the largest subfamily of weevils with over 14,300 species, They are small to medium-sized phyllophagous weevils with deciduous mandibular process and mostly root-feeding larva. History. World catalogue of Entiminae (WCE) has been started in 2007 as an ongoing long-term project, during the preparation of Catalogue of Palaearctic Coleoptera and my postdoctoral project (at ZIN) titled Morphological adaptation in Entiminae weevils. Maintenance. Since 2007 WCE has been maintained on http://dmitriev.speciesfile.org/search.asp?lng=En&keyN=&key=Curculio&f= Since 2015 is under maintenance on Catalogue of Life http://www.catalogueoflife.org/col/details/database/id/166. Since 2017 on http://ukrbin.com/index.php?id=22368&taxamodefm=0&taxamodesp=0 Data availability. The database provides taxonomic information on species-level, data on distribution on both occurrences (specimens) and checklist level (countries). Biological links include host plants, parasites, parasitoids and predators. All available references will be included. The project is open to collaboration.
