Revalidation and systematic revision of the Chilean genus Callyntra Solier(Coleoptera : Tenebrionidae)

The genus Callyntra Solier (Pimeliinae: Nycteliini), distributed in central Chile, is restored, revised, and redefined including 16 species formerly a ssigned to the genus Epipedonota Solier. The use of new morphological featu res such as genital structures and internal skeletal anatomy, together with external morphology, establish that the species of Callyntra are not conge neric with the species of Epipedonota. New synonymies are Epipcdonota opaca Pena under Callyntra inflata (Pena), Epipedonota rugulosa Gemminger under Callyntra unicosta Solier, and Epipedonota schlingeri Pena under Callyntra rossi (Kulzer). Other valid species of the genus are C. multicosta (Guerin- Meneville), C. servillei Solier, C. laticollis Philippi and Philippi, C. ca rbonaria Philippi and Philippi, C. macrocosta (Guerin-Meneville), C. rugosa (Waterhouse), C, penai (Kulzer), C. paulseni Fairmaire, C. andina Germain, C. subrugosa (Pena), C. montana (Pena), C. planiuscula (Fairmaire), and C. riverai (Kulzer). Callyntra servillei Solier is designated type species. L ectotypes are designated for C, andina Germain, C. major Germain, C. anthra cina Germain, C. laticollis Philippi and Philippi, C. carbonaria Philippi a nd Philippi, and Epipedonota rugosa Waterhouse. This article includes a red escription of the genus, redescriptions of each of its 16 species, an ident ification key, photographs of habitus, scanning electron micrographs of pro nota and clypeus, drawings of genital features and metendosternites, and di stribution maps.
