Abstract
BACKGROUND: An online database of the described immature beetles from Brazil is presented for the first time based on published literature. The main purpose of this online database is to ensure accessibility to data associated with the described immature Coleoptera from Brazil, which will be useful for future biological, ecological, conservational and biogeographical studies. NEW INFORMATION: More than 9,486 specimens of 248 genera, 282 species and 4 subspecies of 76 Coleoptera families from 15 states and the Federal District of Brazil were found. Taxonomical and ecological information about each species, when available, are given. The dataset of Immatures of Coleoptera described from Brazil are available and can be accessed through the portals of GBIF at http://www.gbif.org/dataset/8e0e9330-e1b2-475a-9891-4fa8e5c6f57f and the SiBBr at http://ipt.sibbr.gov.br/sibbr/resource?r=coleoptera_immature_of_brazil.
