Caeculus fedrae sp. nov. is described from a series of three exemplars from Baltic amber (Eocene). This species is the first fossil representative of the genus Caeculus, the first fossil species of the family not belonging to the genus Procaeculus, and the second species of the genus in Europe. Phylogenetic relationships, morphological features and paleoecological implications of the finding are discussed.
