Megalopta is a widespread neotropical genus of bees in the tribe Augochlorini in family Halictidae, known as the sweat bees.[1] They are the largest of the five nocturnal genera in Augochlorini. Most have pale integumentary pigmentation, and all have large ocelli, most likely a feature of their nocturnal behavior.[2] They live in tropical Central America and the entirety of South America. The subgenus Noctoraptor is cleptoparasitic.[3] They are not known from the fossil record.[4]
Megalopta was first described by Frederick Smith in 1853.[5] The type species is Megalopta idalia, now known as Megalopta amoena.[5][6] Most studies done on Megalopta are focused on M. genalis.
