Colpopyga Semenov, 1954, a chrysidid genus of the tribe Elampini (Chrysididae: Chrysidi- nae) with four Palaearctic and one Nearctic species, is reviewed. The study of internal urites (Noskiewicz & Lorencova, 1963) and new molecular data (Niehuis, pers. comm.) show a generic status of Colpopyga, which is more related to the genus Holopyga Dahlbom, 1854. A new species, Colpopyga nesterovi sp. nov. from Kazakhstan, is described and illustrated; it is easily recognizable by the red-coppery body coloration and shallow, small and sparse punctures. The status of the subspecies Hedychridium flavipes temperatum Linsenmaier, 1959 is updated to species level in the genus Colpopyga (comb. nov.). New generic combinations are also proposed for C. aureiventris (Mercet, 1904), comb. nov. and C. crassa (Bohart, 1978), comb. nov. (all from the genus Hedychridium). The lectotype of Hedychridium flavipes var. cyanomaculatum Trautmann, 1927 is designated. Дан обзор ос-блестянок рода Colpopyga Semenov, 1954 из трибы Elampini (Chrysididae: Chrysidinae), включающий 4 палеарктических вида и 1 неарктический. Изучение вну- тренних уритов (Noskiewicz & Lorencova, 1963) и новые молекулярные данные (Niehuis, личное сообщение) показали самостоятельность Colpopyga и его близость к роду Holopy- ga Dahlbom, 1854. Описан и проиллюстрирован новый вид Colpopyga nesterovi sp. nov. из Казахстана, хорошо отличающийся красно-медной окраской и мелкой, редкой пун- ктировкой тела. Статус Hedychridium flavipes temperatum Linsenmaier, 1959 повышен до видового уровня в роде Colpopyga (comb. nov.). Предложены новые комбинации для C. aureiventris (Mercet, 1904), comb. nov. и C. crassa (Bohart, 1978), comb. nov. (все из рода Hedychridium). Обозначен лектотип Hedychridium flavipes var. cyanomaculatum Trautmann, 1927.
