Pristomyrmex rasnitsyni is an

Late Eocene fossil which was found in Europe.[1]

History and classification

Pristomyrmex rasnitsyni is known from a solitary fossil, the

Bitterfeld and Rovno ambers, being approximately late Eocene in age. The four amber faunas have been shown to share 17 ant species in common, which make up over 80% of the specimens in amber collections studied for a 2009 paper. Though a large portion of specimens from Scandinavian amber are of species found in the other ambers, the overall fauna found is notably different from the other three. About twenty-four genera with thirty-five species of ants have been identified as inclusions in Scandinavian amber.[3]

The fossil was first studied by paleoentomologists Gennady M. Dlussky of the

Alexandr Pavlovich Rasnitsyn.[1]

When described, Pristomyrmex rasnitsyni was the first member of the genus Pristomyrmex to have been described from the fossil record. The modern species are found primarily in Eastern Asia south through the eastern coast of Australia. Most species live in tropical regions, with the species P. punctatus ranging north to temperate Japan on the Southern portion of Hokkaido. P. rasnitsyni is also the first record of the genus from Europe.[1]

Description

The solitary Pristomyrmex rasnitsyni specimen is well preserved with an estimated length of around 3.0 millimetres (0.12 in). The head is shorter than it is wide, with a

alitrunk have a notable and coarse reticulated pattern, while the clypeus, petiole, and post-petiole areas are notably smooth.[1]
