Äkämäsääski Neurepidosis gracilis Spungis Suomelle uutena Tampereelta (Diptera, Cecidomyiidae). [Neurepidosis gracilis Spungis, new to Finland, from Tampere (Diptera, Cecidomyiidae)]

A Porricondylinae gall midge species Neurepidosis gracilis Spungis, 1987 is reported for the first time from Finland. Larvae of the species were collected from pieces of coarse forest detritus and were reared to adults. The collecting site in South Finland, Tampere, was an aspen dominated boreal forest. Members of the genus Neurepidosis Spungis are rarely collected and poorly known; N. gracilis was hitherto known from Latvia and South Sweden only. Based on our record presented here, N. gracilis is a forest detritus associated species. The main diagnostic characters of the species are present in the male hypopygium: ventroapical margin of gonocoxites is slightly concave and gonostylus has a large, hyaline basal lobe.
