Checklist of dragonflies and damselflies (Insecta: Odonata) of the Amazonas state, Brazil

Abstract: Here we provide a checklist of the odonates from Amazonas state, Brazil. We registered 324 species and 101 genera, making Amazonas the Brazilian state with the most Odonata species recorded. The families with the highest number of species were Coenagrionidae with 32 genera and 101 species, followed by Libellulidae with 28 genera and 100 species and Gomphidae with 12 genera and 45 species. Some regions of Amazonas state remain poorly explored, such as the southern area, and large municipalities, such as São Gabriel da Cachoeira. This work underlines the importance of the biological diversity from Amazonas state and the Amazonian Biome for Odonata species richness in Brazil and shows that many areas in the world’s largest tropical forest have not yet been sampled.

摘要：本研究提供了巴西亚马逊州的蜻蛉目（Odonata）物种名录。本次研究共记录到324个物种及101个属，使得亚马逊州成为巴西境内已记录蜻蛉目物种数量最多的州。物种丰富度最高的科级类群为细蟌科（Coenagrionidae），包含32个属与101个物种；其次为蜻科（Libellulidae），含28个属与100个物种；春蜓科（Gomphidae）则有12个属与45个物种。亚马逊州部分区域仍存在调查不足的情况，例如南部区域，以及圣加布里埃尔达卡谢拉（São Gabriel da Cachoeira）这类大型市镇。本研究凸显了亚马逊州及亚马逊生物群系的生物多样性对于巴西蜻蛉目物种丰富度的重要意义，并揭示了这座全球最大热带森林内的诸多区域尚未开展过物种采样工作。
