A distinctive new species of the extinct ephydroid fly genus, Protocamilla Hennig (Camillidae), is described in mid-Eocene (45 myo) Baltic amber: Protocamilla groehni, n.sp. The unique male specimen has pedunculate eyes, which is presumably a sexual dimorphism as in Drosophilidae. Fore tarsi are also sexually dimorphic. This is the fifth ephydroid to be described from Baltic amber and the only hypercephalic ephydroid known outside the Drosophilidae. The phylogenetic position of Protocamilla is briefly discussed.
