Interpretive Summary: Most bees search for food on flowers during the day but some forage at night. Megalopta is a genus of dark-loving bees that live in dead, broken branches in tropical forests from Mexico to Brazil. A few rare species are parasites on nests of other Megalopta. We describe and illustrate two new species of Megalopta from Mexico and Ecuador. We also provide a guide to identify the species from Central America and those that are parasites on other Megalopta.

Technical Abstract: Two new species of the nocturnal bee genus Megalopta are described: M. (Megalopta) tetewana, n. sp., from Mexico and M. (Noctoraptor) huaoranii, n. sp., from Ecuador. Identification keys to the Mesoamerican species of Megalopta s. str. and the species of the cleptoparasitic subgenus Noctoraptor are presented.
