Evaluation of the RAPD profiles from different body parts of Euglossa pleosticta Dressler male bees (Hymenoptera: Apidae, Euglossina).

In the current literature, information is scarce on which part of the adult insect body is suitable for isolation of genomic DNA for genetic analysis based on DNA-markers. In this study, we evaluated RAPD profiles generated from total genomic DNA isolated from distinct body parts (head, legs, thorax + wings and abdomen) of 12 males of Euglossa pleosticta Dressler. From the total of bands analyz...

Euglossa obrima, a new species of orchid bee from Mesoamerica, with notes on the subgenus Dasystilbe Dressler (Hymenoptera, Apidae)

A new species of the orchid bee subgenus Dasystilbe Dressler (Euglossini: Euglossa Latreille) is described and figured from a series of males and females collected broadly in Mesoamerica. Euglossa (Dasystilbe) obrima, sp. n., is differentiated from the one known species of Dasystilbe, Euglossa (Dasystilbe) villosa Moure, which occurs only in Panamá and perhaps Costa Rica. The subgenus and its c...

A gynandromorph of Xylocopa nigrocincta Smith (Hymenoptera: Apidae).

We describe a mixed gynandromorph of Xylocopa (Neoxylocopa) nigrocincta from a single specimen from Argentina. The specimen presents bilateral asymmetry, with the right half of its head displaying male characters and the left half displaying female characters; the mesosoma presents male characters mostly in the right half of the prothorax, pronotal lobe and distal half of the fore tibia and in ...

Three new cryptic species of Euglossa from Brazil (Hymenoptera, Apidae)

Three new species of orchid bees are described and figured from the Amazon and Atlantic forests of Brazil. Euglossa clausisp. n., Euglossa moratoisp. n., and Euglossa pepeisp. n. are distinguished from their close congeners Euglossa crassipunctata Moure, Euglossa parvula Dressler, and Euglossa sapphirina Moure, previously placed in the subgenus Euglossa (Glossurella) Dressler, 1982, a demonstra...

First records of melanistic Euglossa (Hymenoptera: Apidae): evolutionary implications.

Neotropical orchid bees (Hymenoptera: Apidae: Euglossina) are conspicuous due to their vivid and metallic colors. Nevertheless, except for a few comments, usually concerning the appropriateness of using coloration as a taxonomic character (e.g. Rebêlo and Moure, 1996; Nemésio, 2005, 2009; Bembé, 2007), virtually nothing is known about color production and evolution in orchid bees. Based on stud...
