The karyotype, morphology and ecology of Glyptotendipes aequalis Kieffer (Diptera, Chironomidae)

The karyotype, morphology of adult, pupae and larvae, and the ecology of Glyptotendipes aequalis Kieffer (1922) are described from material from Finland, and a neotype from the (probably) original German material is designated. 2n = 8. Ist, IInd and IIIrd chromosomes are metacentric, IVth acrocentric. The IVth chromosome has a nucleolus and a Balbiani ring. G. aequalis is karyologically closely related to G. caulicola, differing by a simple inversion step
