Abstract
Two new Neotropical species of Osphya Illiger, 1807, a small genus of tenebrionoid Coleoptera, is described from the old secondary rainforests of the Petén-Veracruz moist forest ecoregion of Belize, based on material housed at the Natural History Museum in London. These are first new species of this genus and family to be described from Central America in nearly 150 years. Keys to the American Osphya and the genera of Osphyidae Mulsant, 1856 are presented for the first time. Lectotypes are designated for O. pallida Champion, 1889 and O. tuberculiventris Champion, 1889 to maintain nomenclatural stability. Images of Champion's types of Central American Osphya are provided. The genus Brasilium Pic, 1917 is moved to the subfamily Scraptiinae Gistel, 1848 of Scraptiidae Gistel, 1848 based on the adult morphology. Type species is designated for the genus Brasilium, and an annotated checklist of its species is presented for the first time.
