Euglossa marianae sp. n. (Hymenoptera: Apidae): a new orchid bee from the Brazilian Atlantic Forest and the possible first documented local extinction of a forest-dependent orchid bee

摘要

The orchid bee faunas of Floresta Nacional do Rio Preto, Reserva Biologica Corrego Grande, and Reserva Biologica Corrego do Veado, in the northernmost portion of the state of Espirito Santo, southeastern Brazil, were surveyed for orchid bees for the first time. A total of 1,603 males belonging to 24 species were attracted to 16 different scent baits and actively collected with insect nets during 100 hours from December, 2009, to February, 2010. One species of Euglossa, known as strongly dependent onwell preserved mature forests, once recorded at the region, was not found in this survey and may indicate the first documented local extinction of an orchid bee species. This species, which Atlantic Forest population has been treated as Euglossa analis Wdstwood, 1840, is here considered a new species, Euglossa marianae sp. n.
