Nest descriptions of Megalopta aegis (Vachal) and M. guimaraesi Santos & Silveira (Hymenoptera, Halictidae) from the Brazilian Cerrado Rev. Bras. entomol.
Santos,Leandro M.; Tierney,Simon M.; Wcislo,William T..
We present the first data on the nesting biology of Megalopta aegis and M. guimaraesi from southeastern Brazil. Nests were collected in the Área de Proteção Ambiental Água Limpa, Bauru, São Paulo state. Our data suggest that nest architecture is conserved throughout all species of Megalopta. Two nests of M. guimaraesi consisted of a single female with brood. Of three M. aegis nests, two contained single females with brood and the third nest contained three adult females, with three times more brood than any single female nest. This observation suggests that social behavior in M. aegis is facultative, as known for other Megalopta species.

Orchid bee baits attracting bees of the genus Megalopta (Hymenoptera, Halictidae) in Bauru region, São Paulo, Brazil: abundance, seasonality, and the importance of odors for dim-light bees Rev. Bras. entomol.
Knoll,Fátima R. N.; Santos,Leandro M..
Nocturnal bees in the genus Megalopta Smith, 1853 are generally collected using artificial light sources. However, between 1993 and 2000, a total of 946 females (no males were captured) were captured using aromatic baits commonly used for orchid bees (Euglossini) in five localities in Bauru region, São Paulo, Brazil. Aromatic compounds used in bait traps were: benzyl acetate, eucalyptol, eugenol, skatole, methyl salicylate, and vanillin. The Megalopta species collected were: M. guimaraesi (71.2% of total number of specimens), M. amoena (28.1%), and M. aegis (0.6%). Using the data from these traps, we showed that there was a positive and significant correlation between the abundance of individuals and meteorological factors, rainfall and temperature. Bees...

Xenochlora meridionalis sp. nov. (Hymenoptera: Apidae), a new halictine bee from eastern Brazil as evidence of past connections between Amazonia and Atlantic Forest Rev. Bras. Zool.
Melo,Gabriel A.R.; Faria,Luiz R.R.; Santos,Leandro M..
ABSTRACT We describe a new species of the bee genus Xenochlora Engel, Brooks & Yanega, 1997, X. meridionalis sp. nov., based on a single female collected in the coastal forests of southeastern Brazil, in the state of Espírito Santo. The disjunct distribution exhibited by Xenochlora, with species in northern South America and in the Atlantic Forest of eastern Brazil, is discussed in light of current knowledge about other taxa with similar distribution pattern.
