Two new fossil Carebara Westwood (1840) species are described from the Late Eocene Bitterfeld and Baltic ambers: C. kutscheri sp. nov. is described based on soldier and workers, and formally could be attributed to the former genus Pheidologeton Mayr, 1862 (now junior synonym of Carebara); its workers differ clearly from those of any known fossil Carebara species by the much bigger, well-developed eyes, while eyes in the other species are vestigial, containing several facets, and soldier is the first known one for the fossil Carebara species. Carebara groehni sp. nov. is described based on male, and differs clearly from males of C. antiqua (Mayr, 1868) by the distinctly longer antennal scape and the shorter funicular segments. Furthermore, it is somewhat smaller (the total length is ca. 4 mm vs. ca. 5 mm in C. antiqua), with the gradually rounded propodeum, while propodeum in the latter species is slightly angulate. Additional data for males of C. antiqua, including morphometrics, is provided. Taxonomic position of several fossil species ascribed to Carebara, is discussed.
