Abstract

The Neotropical genus Heteragrion Selys, 1862 is the second most speciose among the Neotropical Zygoptera. However, most of its species are poorly known regarding their biology, distribution, and taxonomy, especially those from undersampled areas like Northern Brazil. Here we describe Heteragrion calafatiensis sp. nov. from the coastal environments of the Brazilian Amazon of Par state (Holotype , Brazil, Par, municipality of Magalhes Barata, near the Marapanim River, (-0.863291, -47.668058, 20 m, 26.ix.2021), C.C. Mendoza-Penagos leg, in UFPA). This is the nineth Heteragrion species recorded for the Northern region of Brazil. The new species can be separated from congeners by cercal morphology and thoracic coloration pattern.

摘要

新热带异蜻属（Heteragrion Selys, 1862）是新热带蜻蛉目中第二大的属。然而，该属的大多数物种在生物学、分布和分类学方面知之甚少，特别是在像巴西北部这样采样不足的地区。本文描述了来自巴西亚马孙地区帕拉州沿海环境的新种 Heteragrion calafatiensis sp. nov. （模式产地：巴西，帕拉州，马加拉什巴腊塔市附近的马拉帕尼姆河（-0.863291，-47.668058，20 米，26.ix.2021），C.C. Mendoza-Penagos 采集，在 UFPA）。这是巴西北部记录的第九种异蜻属物种。新种可通过肛附器形态和胸部颜色模式与近缘种相区分。
