Charipinae collected in different regions of Mexico have been studied. Twelve species are cited for the first time: Alloxysta arcuata (Kieffer, 1902), Alloxysta brevis (Thomson, 1862), Alloxysta castanea (Hartig, 1841), Alloxysta fuscicornis (Hartig, 1841), Alloxysta mullensis (Cameron, 1883) ; Alloxysta victrix (Westwood, 1833 ); Phaenoglyphis americana Baker, 1896; Phaenoglyphis calverti Andrews, 1978; Phaenoglyphis falcata Andrews, 1978; Phaenoglyphis stenos Andrews, 1978; Phaenoglyphis stricta (Thomson, 1877); and Phaenoglyphis villosa (Hartig, 1841). Three new species are described: Alloxysta evenhuisi Ferrer-Suay & Pujade-Villar n. sp., Alloxysta mexicana Ferrer-Suay & Pujade-Villar n. sp., and Alloxysta sarae Ferrer-Suay n. sp. The genera Alloxysta and Phaenoglyphis are cited for the first time from Mexico. A key to all Mexican Charipinae is given. New hosts and trophic relationships are presented for some species.
