Abstract

Изучено 108 экз. муравьев из ровенского янтаря, из которых 101 определен до подсемейства, 93 — до рода и 80 — до вида. Описаны Dolichoderus zherichini Dlussky sp. n., Tapinoma aberrans Dlussky sp. n., T. electrinum Dlussky sp. n., Oligomyrmex nitidus Dlussky sp. n., O. ucrainicus Dlussky sp. n.

One hundred and eight specimens of ants from the Eocene Rovno amber are studied, with 101 specimens being identified up to the subfamily, 93 to the genus and 80 to the species level. Described as new are Dolichoderus zherichini Dlussky sp. n., Tapinoma aberrans Dlussky sp. n., T. electrinum Dlussky sp. n., Oligomyrmex nitidus Dlussky sp. n., O. ucrainicus Dlussky sp. n. About 74% ant specimens belong to species also known in the Baltic amber. However, in terms of relative species abundance the two assemblages are essentially different. In the Rovno amber assemblage, about 26% of ant specimens are represented by the new genera and new species. In contrast, new collections of Baltic amber of similar size yield much less proportion (normally 2—5%) of specimens belonging to new species. Also, about 70% of Rovno ant specimens belong to recent genera, as opposed to about 52% in the Baltic amber.
