Database contains specimen records from the Coleoptera collection of the Naturalis Biodiversity Center (Leiden, Netherlands). The specimens come from the National Museum of Natural History (RMNH; Rijksmuseum voor Natuurlijke Historie), later National Museum of Natural History, Naturalis in Leiden, Zoological Museum Amsterdam (ZMA) (mostly not digitised) and Wageningen University. This dataset is an abstract of the Naturalis production database (BRD) of 12-Dec-2012. The dataset "Zoological Museum Amsterdam, University of Amsterdam (NL) - Coleoptera_Types_Orient" is still separately hosted at GBIF, and not included in this dataset. The collection is largely arranged according to the Coleopterorum Catalogus but the family classification is currently updated to Bouchard e.a. 2011. Therefore classification can be inconsistent at the moment. The bulk of the data originate from a digitization project and need further clean up. Many taxa are not digitised below generic level. Important collections come from the Netherlands, the former Dutch East Indies (now Indonesia) and Surinam (formerly Dutch Guyana).
