Chironomus yoshimatsui Martin and Sublette 1972, a Japanese endemic, is described in Russia for the first time. It was found on Sakhalin Island and in the vcinity of the city of Vladivostok. The identity of standard banding sequences was established in Japanese and Far Eastern Ch. yoshimatsui populations. The Far Eastern populations turned out to be more polymorphic: nine new invrsion sequences were recorded. Heterozygous larvae comprised about 90% of the Vladvostok population and 19% of the Sakhalin one. Eighteen banding sequences and 20 genotypic combinations were revealed in the Ch. yoshimatsui karyiotype. Photomaps of polytene chromosomes and their inversion variants are presented. The С and D arms were mapped for the first time.
