Principal Investigators Brett C. Ratcliffe and Ronald D. Cave

The 116 species of dynastine scarabs that occur in Honduras, Nicaragua, and El Salvador were comprehensively reviewed between October 1998 and March 2006 and published in a monograph of the Bulletin of the University of Nebraska State Museum. This project was a continuation of research on the dynastine fauna of Costa Rica and Panama begun by Ratcliffe. Keys, descriptions, distributions, and notes on biology were provided for all species as well as illustrations, maps, synopses of higher-level taxa, a glossary, a gazetteer of place names, and a species checklist. Nine new species were described. Three species were placed into synonymy. Seventy new country records were recorded. Partner organizations included the Escuela Agrícola Panamericana in Honduras, Museo de Historia Natural in El Salvador, and Museo de Entomológico in Nicaragua.

Research activities consisted of gathering specimen data from all the principal museum collections in the USA and Canada as well as all of those in the study area. All seven research collections housing Coleoptera in the study area had their material identified, augmented, curated, and databased. Several research/collecting trips (see list) were conducted with all the principal participants in all three countries. The database now has 21,150 entries for the study area. Training sessions on dynastine systematics were given to participants in El Salvador from the Museo Nacional, University of El Salvador, Agriculture Department, Forestry Department, and Parks Department.

Outreach Activities included coordination with a Fundación VIDA project, Capacitación de Maestros, Guardarecursos y Guías Naturalistas e Inventario de Insectos en Dos Areas Protegidas y sus Comunidades (Training of Teachers, Park Guards, and Nature Guides and Inventory of the Insects in Two Protected Areas and their Communities), which augmented the project by training teachers and park guards and producing posters that prominently displayed dynastines. The posters, “Insectos de Honduras: Scarabaeidae” and “Insectos Endémicos de Honduras”, were distributed to schools and non-governmental conservation agencies in Honduras. An on-line video in Spanish on 'What is a Scarab?' by Ron Cave was produced. Contributions to education and human resources consisted of training staff and students about collections management, field techniques, databasing, and faunistic surveys; training of a PhD graduate student and two undergraduate volunteers in the USA; and training of parataxonomists, park guards, and park administrators in Honduras about biodiversity. School presentations in Honduras and media exposure (T.V., magazines, newspapers) about biodiversity promoted learning, thus empowering students to be more involved with conservation and supportive of science endeavors.
