Coleoptera es uno de los órdenes más diversos en el planeta y Colombia es uno de los países con mayor biodiversidad. La combinación de estos dos factores determina indiscutiblemente una elevada concentración de especies, cuyas consecuencias sólo se conocen parcialmente en el país. En este trabajo se presenta un ensayo sobre la diversidad de coleópteros en Colombia, resaltando el papel de las colecciones entomológicas y los vacíos de información a la hora de abordar la coleóptero-fauna nacional. Esta contribución constituye un punto de partida para que los coleopterólogos de Colombia comencemos a trabajar colectivamente hacia un conocimiento más amplio y menos fragmentado sobre la historia natural, sistemática, ecología y biogeografía del grupo.
We report an inventory of the superfamily Scarabaeoidea present at the campus of the University of Sucre, Sincelejo, Colombia. Specimens were captured between the months of May and June 2016. A total of 510 specimens were collected belonging to 3 families, 8 subfamilies, 27 genera, and 34 species. The subfamilies presenting the greatest diversity were Scarabaeinae and Dynastinae. For the first time the following 8 species were recorded for Sucre Department: Anomala valida Burmeister, 1844, Liogenys quadridens (Fabricius, 1798), Megasoma elephas (Fabricius, 1775), Omorgus suberosus (Fabricius, 1775), Phileurus didymus (Linnaeus, 1758), Phileurus valgus (Olivier, 1789), Phyllophaga menetriesi (Blanchard, 1850), and Xenopelidnota anomala (Burmeister, 1844). We highlight the importance of green zones within urban areas as possible faunistic refugia for different taxonomic groups, especially for the beetles of the superfamily Scarabaeoidea.
A new species of Stizocera (Cerambycinae, Elaphidiini) from Colombia is described and illustrated: Stizocera ruthveronae sp. nov., and an updated key to species of the genus is presented. Moreover, nine species of longhorn beetles of Cerambycinae belonging to Callichromatini, Eburiini, Elaphidiini, Hexoplonini, Neoibidionini, Obriini are reported for the first time for Colombia.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
