The aim of this study was to investigate the diversity and distribution patterns of orchid bees (Euglossina). Cluster and correlation analyses were applied to data extracted from 28 orchid-bee surveys throughout the Neotropical Region. The 28 sampling sites were grouped in three main biogeographic areas that roughly correspond to the Amazonian Basin, the Atlantic Forest and Central America. These three regions, as well as subregions within each of them, correspond approximately to biogeographic components identified through phylogeny-based analyses for other bees and organisms. The Amazonian Forest as a whole has the richest fauna and the highest levels of endemism. The Atlantic Forest, on the other hand, showed the poorest fauna and the lowest levels of endemism. However, a major neotropical biome, in which orchid bees are known to occur, has not been sampled yet, the savanna-like cerrado. At least 30% of the species are endemic to each biome. An updated checklist of the species of Euglossina is provided.
本研究的目的是调查兰花蜂（Euglossina）的多样性和分布模式。对从新热带地区28次兰花蜂调查中提取的数据进行了聚类和相关性分析。这28个采样地点被分为三个主要生物地理区域，大致对应于亚马逊盆地、大西洋森林和中美洲。这三个区域以及每个区域内的子区域，大致对应于通过对其他蜜蜂和生物进行基于系统发育分析确定的生物地理成分。整个亚马逊森林拥有最丰富的动物群和最高的特有性水平。另一方面，大西洋森林的动物群最贫乏，特有性水平最低。然而，一个已知有兰花蜂出现的主要新热带生物群落——类似稀树草原的塞拉多，尚未进行采样。每个生物群落至少30%的物种是特有种。提供了一份更新的兰花蜂物种清单。
