The Ephemeroptera of Central America Part 3: Belize

The Ephemeroptera fauna of Belize is inventoried based on the study of recent collections and includes nine families, 32 genera and 65 species. Forty-one species are reported from Belize for the first time, including a previously unknown species (Asioplax goldeni n. sp.), which is described herein. The majority of species in Belize have ranges that extend throughout Central America, with some of the species known from the western and southwestern United States as well. Only the northern District of Corozal along with the Orange Walk District remain poorly known with respect to the Belize mayfly fauna.
