The genus Callyntra Solier (Pimeliinae: Nycteliini), distributed in central Chile, is restored, revised, and redefined including 16 species formerly assigned to the genus Epipedonota Solier. The use of new morphological features such as genital structures and internal skeletal anatomy, together with external morphology, establish that the species of Callyntra are not congeneric with the species of Epipedonota. New synonymies are: Epipedonota opaca Peña under Callyntra inflata (Peña), Epipedonota rugulosa Gemminger under Callyntra unicosta Solier, and Epipedonota schlingeri Peña under Callyntra rossi (Kulzer). Other valid species of the genus are: C. multicosta (Guérin-Méneville), C. servillei Solier, C. laticollis Philippi and Philippi, C. carbonaria Philippi and Philippi, C. macrocosta (Guérin-Méneville), C. rugosa (Waterhouse), C. penai (Kulzer), C. paulseni (Fairmaire), C. andina Germain, C. subrugosa (Peña), C. montana (Peña), C. planiuscula (Fairmaire), and C. riverai (Kulzer). Callyntra servillei Solier is designated type species. Lectotypes are designated for C. andina Germain, C. major Germain, C. anthracina Germain, C. laticollis Philippi and Philippi, C. carbonaria Philippi and Philippi, and Epipedonota rugosa Waterhouse. The paper includes a redescription of the genus, redescriptions of each of its 16 species, an identification key, photographs of habitus, scanning electron micrographs of pronota and clypeus, drawings of genital features and metendosternites, and distribution maps.
