The genus Tachidiella Sars, 1909 is revised on the basis of material from Norway, Helgoland, the Celtic Sea and the Antarctic. The type species T. minuta Sars, 1909 is redescribed and compared with previous descriptions of the species. T. minuta sensu Pallares (1979) from Tierra del Fuego is attributed distinct specific status as T. patagonica n. sp. The Baltic record of T. minuta sensu Arlt (1983) is identified as T. reducta n. sp. which occurs sympatrically with T. minuta in Frierfjord/Langesundfjord, Norway. A new species T. kimi is described from Marian Cove in King George Island, South Shetlands and represents the first record of the genus from the Antarctic. T. kimi n. sp. differs from T. reducta n. sp. by the presence of normally developed setae on the caudal rami, P2-P4 enp-3 and P4 exp-3. A key to species is presented.
