Pycnotomina cavicolle


MonotomidGen was created to facilitate the identification New World species of Monotomidae, a small family (36 genera, 258 species) within the superfamily Cucujoidea (sensu Robertson et al. 2015). Monotomidae includes many species that are of economic or ecological significance, some of which are recognized as forest pests, pollinators, myrmecophiles, and melittophiles (Bousquet 2009). Most monotomids are thought to be predaceous or mycophagous.

MontomidGen has several sections with different functions. The Genus Fact Sheets provide detailed information and dozens of photomicrographs about the genera and species occurring in the New World. The Interactive Key is a flexible, matrix driven, multientry key to the New World Genera of Monotomidae (with illustrated choices). Resources are provided to aid those who are inexperienced with identifing monotomids (e.g. What is a Monotomid?, Glossary of Terms, and Anatomical Atlas). The References section contains bibliographic information and links to PDFs for literature that is no longer under copyright protection.
