The male genitalia of the genus Metaselena Diak. are described and illustrated for the first time, and as a result of that the genus is transferred to the Olethreutinae. Eight new species of Metaselena - lepta, rhabdota, symphylos, pemphigodes, pithana, platyptera, diakonoffi and allophlebodes - are described and illustrated. The systematic position of Metaselena, so far known only from Australia and New Guinea, is briefly discussed and the close association of the genus with Eucosmomorpha Obr. is pointed out.
