Fennica 16: 301—304. Lepimormia hemiboreale sp. n. (Diptera, Psychodidae) from Estonia, Saaremaa Island, is described. The description ofthe species is based on Malaise trap mate- rial collected from an eutrophic spring fen in Viidumae Nature Reserve. Lepimormia hemiboreale sp. n. is quite similar to L. georgica (Wagner, 1981), L. sibirica Jeiek, 1994 and L. vardarica (Krek, 1982) but the shape of aedeagus, subgenital and anal valves readily distinguish L. hemiboreale sp. n. from these. In addition to the new species, 13 moth fly species are reported for the first time from Estonia. J. Salmela, Department ofBio— and Environmental Sciences, P. 0.
