GENERA AGRIOTES ESCHSCHOLTZ, ECTINUS ESCHSCHOLTZ, TINECUS FLEUTIAUX AND RAINERUS GEN. N. (COLEOPTERA, ELATERIDAE, AGRIOTINI) Giuseppe Platia Via Molino Vecchio, 21a, 47043 Gatteo (FC), Italia – [email protected] Abstract: The Agriotes Eschscholtz and Ectinus Eschscholtz of China are revised, with the descriptions, respectively, of 26 and 18 new species. Rainerus, gen. n. with 12 species (11 new), is separated from Ectinus Eschscholtz on the basis of mor- phological characters and particularly the shape of the sclerotic plates of the bursa copulatrix; it also includes two species from Taiwan, one from Myanmar and a new one from Laos. Tinecus Fleutiaux, described with four species from Vietnam, is recorded from China for the first time, with a new species; a further 3 new species are described from Myanmar, Thailand and Laos.

El género Rainerus, gen. n., con 12 especies (11 nuevas), se separa de Ectinus Eschscholtz en base a ca- racteres morfológicos y en particular a la configuración de las piezas esclerotizadas de la bolsa copulatriz; incluye también dos especies de Taiwán, una de Myanmar y una nueva de Laos. Tinecus Fleutiaux, descrito sobre cuatro especies de Vietnam, se cita por primera vez de China, con nuevas especies; se describen otras tres nuevas especies de este género, de Myanmar, Tailandia y Laos.
