FOLIA ENTOMOLOGICA HUNGARICA ROVARTANI KÖZLEMÉNYEK XLVIII 1987 P- 217-224 Two new Plusiinae (Lepidoptera: Noctuidae) species from Mongolia By L. RONKAY (Received January 1, 1987) Abstract: Two new Plusiinae (Lepidoptera: Noctuidae) species from Mongolia, Description of Abrostola gabori and Euchalcia exornata spp. n. from Mongolia is given. In 1986 two groups of Hungarian lepidopterists were on zoological expedition in Mongolia, and they collected a very large and interesting Noctuidae material. This material contains numerous taxa of Plusiinae of which two species are new for science. Beside them, there are several specimens of the Autographa monoramma (Alphéraky, 1887) - camptosema (Hampson, 1913) group belonging to five distinct species. The taxonomic problems of this group seem to be very difficult, therefore, a full revision is needed. This revision is under preparation in co-authorship with Dr. Z. KLYUCHKO (Kiev). The list of the collected Plusiine species and their data will be published - in agreement with the collectors and the specialists working on the noctuid material - in a comprehensive zoogeographical paper on the Noctuidae fauna of Mongolia. The descriptions of the new taxa with the discussions on their zoogeographical and taxonomic relationships are given below. Abrostola gabori sp. n. (Plate: 1) Type material: Holotype: male.
