Abstract

Xiphocentronidae comprises eight genera found across tropical regions. In Brazil, two genera are present: Xiphocentron Brauer, 1870 and Machairocentron Schmid, 1982. Xiphocentron is further divided into five subgenera: Xiphocentron (Antillotrichia) Banks, 1941, X. (Glyphocentron) Schmid, 1982, X. (Rhamphocentron) Schmid, 1982, X. (Sphagocentron) Schmid, 1982, and X. (Xiphocentron). Xiphocentron (Antillotrichia) is the most species-rich subgenus and the only one occurring in South America. In Brazil, there are 18 species of X. (Antillotrichia), mainly distributed in the Atlantic Forest, with one species recorded in the Brazilian Amazon. Machairocentron, another Neotropical genus, comprises nine species, but only one species is known in Brazil. Recent research in the Brazilian Amazon led to the discovery of three new species of Xiphocentron: Xiphocentron (Antillotrichia) moa sp. n., Xiphocentron tapajos sp. n., and Xiphocentron (Antillotrichia) xingu sp. n. This study describes and illustrates these species, focusing on adult males, and highlighting the distinctive morphology of segment IX and inferior appendages. New distribution records are provided for X. (Antillotrichia) sclerothrix Pes & Hamada, 2013 and M. falciforme Pes & Hamada, 2013 . Additionally, M. amahuaca Vilarino, Salles & Bispo, 2023 and X. (Antillotrichia) surinamense Flint, 1974 are reported for the first time in Brazil.

巴西亚马逊河流域的网管蝶（毛翅目：精神鞘翅目：Xiphocentronidae）：新物种的发现和新分布记录的报告

Xiphocentronidae 包括 8 个属，分布于热带地区。巴西有两个属：Xiphocentron Brauer, 1870 和 Machairocentron Schmid, 1982。Xiphocentron 又分为五个亚属：Xiphocentron (Antillotrichia) Banks, 1941, X. (Glyphocentron) Schmid, 1982, X. (Rhamphocentron) Schmid, 1982, X. (Sphagocentron) Schmid, 1982, 和 X. (Xiphocentron)。Xiphocentron（Antillotrichia）是物种最丰富的亚属，也是唯一出现在南美洲的亚属。在巴西，有 18 个 X.（Antillotrichia）物种，主要分布在大西洋森林，其中一个物种记录在巴西亚马逊河流域。另一个新热带属 Machairocentron 有 9 个物种，但在巴西只有一个物种。最近在巴西亚马逊河流域的研究发现了三个新的Xiphocentron物种：Xiphocentron (Antillotrichia) moa sp.提供了 X. (Antillotrichia) sclerothrix Pes & Hamada, 2013 和 M. falciforme Pes & Hamada, 2013 的新分布记录。此外，M. amahuaca Vilarino, Salles & Bispo, 2023 和 X. (Antillotrichia) surinamense Flint, 1974 首次在巴西被报道。
