By attracting male orchid bees with eight chemical baits in the gallery forest of the Parque Nacional da Chapada dos Guimarães, southern Mato Grosso state, Brazil, I found several males belongs to all Euglossini bee genera. Male euglosine bees were collected monthly using an entomological net as they arrived at the baits. From September 2003 to July 2005, the baits were applied to absorbent paper pads from 8:00 AM to 4:00 PM. From 24 collections, a total of 264 males were captured, spread throughout the five genera of the tribe and belonging to 30 valid species. Of all the males collected, only one was Euglossa cognata Moure, reported to occur from Costa Rica to southern Brazil, and herein recorded to the Platina Basin for the first time. The results clarify the distributional gap and amplified the geographic distributional range of E. cognata in South America.
