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) moasp. n., Xiphocentron tapajossp. n., and Xiphocentron (Antillotrichia) xingusp. 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.
