The karyotype of Stenochironomus gibbus F. (2n = 8) is described for the first time. Chromosomes: I(AB) > or = II(CD) > or = II(EF) > IV(G). Larvae of this species undermine submerged wood. Low degree of polyteny and poor development of active regions is characteristic of this species polytene chromosome structure, which is probably due to diminished function of salivary glands of the larvae that do not build web shelters.
