Middle and hind tibiae each with one short simple spur. Petiole as long as broad, with low and thick scale, a little more than twice as broad as long, rounded above, with convex anterior and posterior surfaces.

Maximum eye diameter 2-3 times less than head length and 1.8-3.5 times less than head width. Ocelli usually lacking. Frontal carinae short but prominent, extending to the middle of the anterior orbits. Frontal area small and indistinct. Clypeus broader than long, its posterior border extending back medially between the frontal carinae. Anterior clypeal border projecting in the form of a short broad rounded lobe. Antenna short 8-jointed. Scape not reaching to the posterior orbits. Funiculus incrassated but without distinct clave; joints 1 and 2 of the funiculi subequal, about twice as long as thick, joints 3 and 4 about 1.5 times as long as thick, 5 and 6 scarcely longer than thick, the terminal joint a little longer than thick. Mandibles stout, not decussating when closed, with convex external margin and 8 to 9-toothed masticatory margin. The teeth are stout; the apical tooth is longest; shorter teeth are alternating with the longer ones towards the base. Maxillary palps short, do not reach the occipital foramen. Mesosoma long, narrower than the head, constricted in the mesopropodeal region. Pronotum gradually convex, about as long as broad. Mesonotum longer than broad and broader in front than behind; laterally its surface is straight and gradually sloping backward, its sides compressed.

Frontal carinae and lobes absent. Frontal furrow distinct. Anterior clypeal margin projecting as a rounded lobe. Antenna geniculate, small.

Comments. There is a problem with the association of different castes of fossil ant species as findings of males, females and workers of the same species in the same piece of amber are extremely rare. However we are confident that workers, male and female of

described above belong to the same species. Up to the present 231workers of

from Baltic and similar ambers are studied: 18 by Mayr (1868), 7 by Andre (1895), one by Emery (1905), 172 by Wheeler (1915) and 33 (excluding species determined by Wheeler) by one of us (GMD). All these specimens belong to the same species G

. So there is a high possibility that the two studied males (one by Mayr, and one by us) and above described gyne belong to the same species. The gyne has small eyes relative to those of the workers. This is unusual for ants, but
