A New Ant Genus (Hymenoptera, Formicidae) from the Late Eocene Rovno Amber

Keywords: ants, Formicidae, Dolichoderinae, Dolichoderini, new genus, new species, Damzenomyrmex ribbeckei, late Eocene, Europe, palaeontology, taxonomy


Based on workers from the Late Eocene Rovno amber (Ukraine), Damzenomyrmex gen. n. (Dlichoderinae) is established to include Damzenomyrmex ribbeckei sp. n., which is described here. I consider Damzenomyrmex to be a relative of Dolichoderus s. l. and assign it to the tribe Dolichoderini. Damzenomyrmex differs well from representatives of the previously established subgenera (genera) of Dolichoderus s. l., such as Dolichoderus s. str., Karawajewella, Acanthoclinea, Monoceratoclinea and Diceratoclinea by the nature of the mesosomal armature. It differs from the species of Hypoclinea in the presence of horn-like projections on the anterolateral corners of the pronotum. Regarding the last character, Damzenomyrmex reminds the species of Monacis, but readily differs from them by the non-concave posterior propodeal margin, a different shape of the petiolar scale, a not laterally marginated mesonotum, and some other characters. Furthermore, Damzenomyrmex differs from all Dolichoderus s. l. species in the cuticular structure and in the serration pattern of the mandibles, with the masticatory margin having 6–7 minor sharp teeth and a much longer apical one, the basal angle distinct and the basal margin lacking teeth or denticles. The comparative composition of Dolichoderinae and representatives of other ant subfamilies in late Eocene European ambers is considered.
