Abstract

The Neotropical genus Heteragrion Selys, 1862 is one of the most speciose among Zygoptera. Notwithstanding, most of its species are poorly known, especially those from undersampled areas such as Northeastern Brazil. Here, we describe Heteragrion lencionii sp. nov., from protected areas of Sergipe state (Holotype ♂, Brazil, Sergipe, Areia Branca, Serra de Itabaiana National Park, -10.7484, -37.3390, 179 m, 7.xii.2020, A.B. Farias A.E. dos Santos leg., in UFS). This is only the second Heteragrion species discovered as new for the Northeastern region of Brazil, separated from other congeners by cercus morphology and thoracic coloration pattern.

摘要

新热带异蜻属（Heteragrion Selys, 1862）是蜻蛉目（Zygoptera）中物种最丰富的属之一。尽管如此，该属的大多数物种仍知之甚少，尤其是在巴西东北部等采样不足的地区。在这里，我们描述了来自塞尔希培州（巴西，塞尔希培，阿拉伊巴尼亚纳山脉国家公园，-10.7484，-37.3390，海拔 179 米，2020 年 12 月 7 日，A.B. 法里亚斯和 A.E. 多斯桑托斯采集，保存在 UFS）的异蜻属一新种 Heteragrion lencionii sp. nov.。这是巴西东北部发现的第二种新的异蜻属物种，与其他近缘种的区别在于尾须形态和胸部颜色模式。
