Introduction
Bolívar Rafael Garcete-Barrett is an Entomologist and currently works at the Museo Nacional de Historia Natural del Paraguay, and teachs Entomology at the Departamento de Biología, Facultad de Ciencias Exactas y Naturales, Universidad Nacional de Asunción. Bolívar Rafael does research in Zoology, Entomology and Botany. His current main long term project is 'Total curation of the insect collections of the Museo Nacional de Historia Natural del Paraguay'. His main expertise is on Vespidae of the Neotropical Region, with emphasis on Eumeninae, but is currently working with several other gruops of insects in order to execute his main project and the many identification requests from several Paraguayan institutions.
