Abstract

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.

Oito iscas-odores foram utilizadas para atrair machos das abelhas Euglossini na floresta de galeria do Parque Nacional da Chapada dos Guimarães, sul de Mato Grosso. De setembro de 2003 a julho de 2005, uma vez por mês, das 08:00 às 16:00 horas, os machos foram capturados conforme chegavam às iscas-odores. Durante as 24 coletas, foram capturados 264 machos, distribuídos pelos cinco gêneros da tribo e pertencentes a 30 espécies válidas. Do total de machos coletados, apenas um era de Euglossa cognata Moure, espécie com distribuição geográfica desde a Costa Rica até o sudeste do Brasil, todavia sem registro anterior para a Bacia Platina. O resultado aqui apresentado amplia a distribuição geográfica de E. cognata na América do Sul.

The Bees of the World

Charles Duncan Michener (2000)

A comprehensive, worldwide treatment of all groups of bees - 1200 genera and subgenera, including more than 16,000 species. In extensive introductory sections, Charles D. Michener examines the evolution of bees from wasps, the relations of the families of bees to one another, the evolution of bees in relation to that of flowering plants, the nesting behaviour of solitary and social bees, and the structure of immature and adult bees. Drawing on these considerations as well as the fossil record, he speculates on the attributes of the protobee, the common ancestor of all bees. He also cites the major literature on bee biology and describes the need for further research on the systematics and natural history of bees, including their importance as pollinators of crops and natural vegetation.
