Exomalopsis
Exomalopsis is a genus of solitary bees in the family Apidae, tribe Exomalopsini, comprising nearly 90 described species with many more undescribed. These bees are restricted to the Western Hemisphere, occurring in both Neotropical and Nearctic realms. Species nest communally in soil, excavating deep tunnels with branching underground pathways leading to individual brood cells. The genus is notable for its complex associations with kleptoparasitic cuckoo bees and parasitoid wasps.
