Palaearctic material of the genus Heterocola Förster was studied, the holotypes of four species were examined and re-described. Heterocola concava (Uchida) from Japan is transferred to Phradis Förster (comb. nov.), and the genus Heterocola is excluded from the fauna of Japan. Specimens of H. proboscidalis (Thomson) and H. rufiventris Horstmann deposited in the Zoological Institute RAS (St Petersburg) and briefly mentioned from the former USSR by K. Horstmann in his revision (1981) are found and re-exam- ined, and their complete label data are provided. Extensive faunistic records of the Palaearctic species of Heterocola primarily based on the Zoological Institute RAS collection are provided. Colour photographs of six species are given for the first time. An identification key to six species of Heterocola occurring in the Palaearctic region is provided; taxonomic status of the seventh species, H. pappi Kolarov, is not clear. Резюме. Изучен палеарктический материал рода Heterocola Förster, исследованы и переописа- ны голотипы 4 видов. Вид H. concava (Uchida) из Японии перемещен в род Phradis Förster (comb. nov.), в связи с чем род Heterocola исключен из фауны Японии. Экземпляры видов H. probosci­ dalis (Thomson) и H. rufiventris Horstmann, хранящиеся в коллекции Зоологического института РАН (Санкт-Петербург) и упомянутые с территории бывшего СССР К. Хорстманном в его ре- визии (Horstmannn, 1981), найдены в коллекции, изучены, и даны полные данные их этикеток. Представлены обширные новые сведения о распространении палеарктических видов Heteroco­ la (главным образом по материалам Зоологического института РАН). Впервые даны цветные фотографии 6 палеарктических видов. Подготовлен ключ для определения 6 палеарктических видов Heterocola; таксономический статус седьмого вида, H. pappi Kolarov, требует уточнения.
