D3219: Species discovery in Southern African bee flies: A new species in the revised genus Enica

Bee flies (Diptera: Bombyliidae) are a global family of true flies that are ecologically significant pollinators, especially in South Africa. Describing new species and taxonomic revisions makes it easier to document bee flies for ecological and human impact studies. However, for the genera Enica and Nomalonia, the last review in 1956 by Albert John Hesse was wordy, comparative, and suggested but did not establish a synonymy of the genera. We used over 300 specimens that had accumulated in the Iziko South African Museum, KwaZulu Natal Museum, and Smithsonian to revise these two genera of South African bee flies. We established Enica and Nomalonia as synonymous, redescribed known species, described a new species, and created a simplified dichotomous key with photograph references. Enica is a monotypic genus differentiated from Nomalonia (6 named species) only by two cross veins in the r₁ cell and setation below the antennae. Due to similarities in color pattern, body shape, setae, and terminalia, these genera will be synonymized under the name Enica. Known species were redescribed, and a new species with setation and geographic distribution differences was described. The revision of Enica improved species identification for future researchers and increased knowledge of global biodiversity.
