Description
Summary:The karyotype and morphology of Chironomus brevidentatus sp. n. has been described from the Lokka reservoir in northern Finland. The species belongs to the thummi complex with the chromosome arm combination AB, CD, EF and G. The relationships between the karyotypes of C.brevidentatus, C. major Wülker & Butler, C. neocorax Wülker and Butler, C. tardus Butler, and "Chironomus sp. 2n = 6, Lokka" are described. The external morphology has been compared with the suggested nearest relatives or otherwise similar species. The known ecological conditions in the type locality are discussed.
