Darkling beetles (Coleoptera: Tenebrionidae) are one of the most numerous and diverse family of beetles, present in almost all agroecosystems. The fauna of these beneficial insects in chain foods of ecosystems was studied in Iranian rice fields and surrounding grasslands. The results show a total of 21 tenebrionid species of 16 genera including, Zophosis LATREILLE, Dailognatha ESCHSCHOLTZ, Tentyria LATREILLE, Eutagenia REITTER, Phymatiotris SOLIER, Pachyscelis SOLIER, Pimelia FABRICIUS, Dendarus DEJEAN, Colpotus MULSANT et REY, Gonocephalum SOLIER, Opatroides BRULLÉ, Blaps FABRICIUS, Cephalostenus SOLIER, Probaticus SEIDLITZ, Euboeus BOIELDIEU and Tribolium MACLEAY. Altogether, members of 3 subfamilies (Pimeliinae, Opatrinae, Tenebrioninae) were collected from Iranian rice fields and surrounding grasslands. Four genera and 14 species are new records for Iran.
