The dung beetles of Venezuela (Coleoptera: Scarabaeidae: Scarabaeinae): catalogue and updated distribution

Abstract

Venezuela’s diverse land ecosystems are grouped into four major regions (coast-islands, low plains, hills and mountains), ranging from sea level up to 4978 m. The Scarabaeinae (Scarabaeidae, Coleoptera) currently encompass 278 genera and 6837 species worldwide, but are poorly inventoried in Venezuela. We reviewed the literature and the material housed at the entomological collection of the Universidade Federal de Mato Grosso (CEMT), Cuiabá, Brazil, and found 32 genera and 149 species of dung beetles as certainly present in Venezuela. Twenty-four of these species are, as far as current knowledge goes, endemic to the country, while another 34 are restricted to Venezuela and the neighbouring countries of Colombia, Brazil, Trinidad and Tobago, and Guyana. Additionally, 36 species are deemed potential inhabitants of the country, whilst 14 others previously recorded in the literature as part of the Venezuelan fauna are here concluded not to be actually present there. Complete literature is listed for each genus and species, and information on type material, material examined, worldwide distribution, and Venezuelan records is also presented.
