Abstract

Three new species of the genus Xiphocentron (Trichoptera, Xiphocentronidae) are described from Nearctic and Neotropical regions of Mexico. Xiphocentron (Glyphocentron) flinti sp. nov. has a very unique morphology distinguished by the presence of long spines on the preapical and apical margin of tergum X. Xiphocentron (Antillotrichia) holzenthali sp. nov. is diagnosed by tergum IX, with the apical margin bearing a narrow, rounded, mesal emargination and by a spiny projection near the basal plate. These species are the first records of the family in northwestern Mexico. Xiphocentron (Antillotrichia) pineroi sp. nov. is recognized, when observed in lateral view, by its less elongate genitalia and the sinuous mesal sclerite of the inferior appendage. Additionally, we provide detailed illustrations of Xiphocentron (Antillotrichia) rhamnes Schmid, and an updated list of the distribution of the genus Xiphocentron in Mexico.
