The Central American key suggests Mallophora, which are bee mimics. There may be additional genera in South America. An unusual character of this genus is the longitudinal crossvein connecting the base of R2+3 with the base of R4 after the fork in R4+5. A few other genera (e.g. Promachus) have it too. The genus was revised in 1980. Eric Fisher, in Manual of Central American Diptera, writes that the genus needs a better revision. Artigas, J.N. & Angulo, A.O. 1980.

Mallophora tibialis is similar. The yellow spot on the tibia, presumably the source of the species name, is probably there to mimic pollen carried by bumblebees (Bombus). It could evolve more than once and might not be a reliable species character.
