Abstract

Electromyrmex wheeleri sp. n., which belongs to the extinct ant genus is described based on males from the Baltic and Bitterfeld Ambers (Priabonian stage, 33.9–37.2 Ma). Until now only one species of this specialized genus based on a single worker was described and taxonomic position of this genus in the subfamily Myrmicinae remains uncertain. By the forewing venation, males of E. wheeleri resemble Aphaenogaster Mayr, Messor Mayr and Pheidole Westwood, but differs from the first two genera by the presence of Mayrian furrows, and from the latter one — by the antennal structure. On the other hand, males of this genus have a set of specialized characters, e. g., subcylindrical petiole, mandibles with an only single apical tooth, quite peculiar shape of mesosoma, etc. and the morphological features of the males of E. wheeleri also do not shed light on its systematic position.
