Abstract

Two new fossil ant species Cataglyphoides komvos sp. nov. and C. konikos sp. nov. are described from late Eocene Rovno amber (Ukraine). The first species has a nodiform petiole and differs from C. dlusskyi Radchenko et Khomych, 2020 by the presence of coarse bristle-like hairs on the tibiae and a double row of bristles on the inner surface of the metatibiae, by the presence of a longitudinal carina on the clypeus, and by the position of the eyes, which are situated far beyond midlength of the sides of the head. Cataglyphoides komvos differs from C. constrictus (Mayr, 1868) by a shorter antennal scape, exceeding the occipital margin by ca. 0.4 of its length, the shorter funicular segments, the 1st to 10th segments < 1.7 times and apical segment < 3.0 times as long as wide, as well as the structure of the maxillary palps. Cataglyphoides konikos resembles C. intermedius Dlussky, 2008 by a non-nodiform petiole with thick scale, and differs from it by subcuneiform scale, the presence of numerous thin erect hairs on the mesosomal dorsum and all gastral tergites, and by the structure of the maxillary palps with the 4th segment somewhat shorter than the 5th. A key to identification of the Cataglyphoides Dlussky, 2008 species is compiled. The taxonomic position of the fossil genera currently assigned to the tribe Formicini Latreille, 1802 is discussed.
