Melyridae Dasytinae and rhadalidae of Cyprus have been studied, based on rather abundant materials from several collections and on the scarce (often obsolete) literature existing. A total of 9 genera and 18 species have been found to live on the Island: photographs or drawings of nearly all of them are provided and a determination key is proposed. Three new species are described: Dasytidius valdelatus n. sp., Dasytiscus anatolicus n. sp. and Aplocnemus (Diplambe) constantini n. sp. Three status changes are proposed, as a necessary anticipation (to be fully justified in a next paper): Dasytidius virescens (baudi di Selve, 1873) and Dasytidius funebris Majer, 1989, previously good species, are considered subspecies of Dasytidius indutus (Kiesenwetter, 1859); Dasytidius similis (Schilsky, 1896), formerly subspecies of D. indutus, is elevated to good species. One new synonymy is proposed: Danacea brevipennis Pic 1932 = Danacea cypria Schilsky, 1897. Dasytes xanthocnemus var. cyprius baudi di Selve, 1873 is not a synonym of Dasytes xanthocnemus Kolenati, 1846 but of Dasytes moniliatus Kiesenwetter, 1863. the variability of 3 species: Dasytes (Mesodasytes) aeneiventris Küster, 1850, Dasytidius inchoatus Majer, 1991 and Aplocnemus (Ischnopalpus) syriacus Schilsky, 1894 is discussed as relevant to their definition. the ♂ of Trichoceble testaceipes Pic, 1921 until now only known through ♀♀, is described. A short distributional analysis, including a rough comparison with the other large Mediterranean island has been attempted.
