Abstract Subfossil Bosmina (Eubosmina) remains were analysed in a sediment core from the Untersee of Lake Constance which covered the Late-Glacial/Holocene period. During the Late-Glacial and the early Holocene the lake was inhabited only by Bosmina longispina Leydig. In the Late Holocene a second species, Bosmina coregoni f. kessleri Uljanin, appeared. In the uppermost sediment layers the morphological gap between the two taxa disappeared, apparently from introgressive hybridization.
