México ABSTRACT Six new species of Mozena, M. atra, M. nogueirana, M. pardalota, M. perezae, M. preclara, and M. presigna, collected in Mexico, are described; dorsal habitus, antennal segments, pronotum, abdomen in lateral view, paramere and male genital capsule of most of the species are illustrated. Key Words: Insecta, Heteroptera, Coreidae, Nematopodini, Mozena, new species, Mexico RESUMEN Seis nuevas especies de Mozena, M. atra, M. nogueirana, M. pardalota, M. perezae, M. pre- clara, y M. presigna, colectadas en México son descritas; el cuerpo en vista dorsal, las ante- nas, el pronoto, el abdomen en vista lateral, los parámeros y la capsula genital del macho de la mayoria de las especies son ilustrados. The genus Mozena Amyot and Serville (1843) (H. S.), M. buenoi Hussey, M. gaumeri Distant, M. is a large, complex group that ranges from the hector Van Duzee, M. lineolata (H.S.), M. lunata Southern United States, throughout Mexico, (Burmeister), M. lunata rufescens Ruckes, M. lur- Cuba, and Central America to Northeastern ida (Dallas), M. lutea (H.S.), M. nestor (Stål), M. South America including Colombia and Venezu- pallisteri Ruckes, M. rufula Van Duzee, M. scrupu- ela, with the greatest number of species being losa (Stål), and M. ventralis (Mayr).
