The predominately Mexican endemic genera Ficinus Distant, 1893 and Jornandes Distant, 1884 are revised. Rhinocapsidea Reuter, 1908 is treated as a junior synonym of Jornandes. Two species of Ficinus are recognized, including one new species from Guerrero. Twenty-five species of Jornandes are recognized, including 20 new species, predominately from the southern edge of the Transmexican Volcanic Belt near the conjunction of the Balsas Basin and the Sierra Madre del Sur of Guerrero, Puebla, and Oaxaca. The new combinations, Jornandes albipes (Kelton, 1969) (Scalponotatus), Jornandes genetivus (Distant, 1884) (Rhinocapsidea), Jornandes sinaloa (Carvalho, 1987) (Rhinocapsidea) are proposed. Jornandes dissimulans Distant, 1983 and J. nordestina (Carvalho and Wallerstein, 1978) (Rhinocapsidea) are considered species incertae sedis. Keys to all recognized species are included. Illustrations of the male genitalia, dorsal habitus color photographs of both sexes (except for J. championi Distant, 1884), and new distributional records of all species are provided. Host records, where known, are listed. Scanning electron micrographs are presented to document the cuticular sculpturing of the corium, lateral view of the head, thorax, mesothoracic spiracle, and metathoracic scent-efferent system of representative species. The female genitalia of F. sagittarius and three species of Jornandes are documented with photographs.
