Among social insects, army ants are exceptional in their voracious
coordinated predation and nomadic life history: the synthesis of these
remarkable ecological traits is referred to as the army ant syndrome.
Despite molecular evidence that the army ant syndrome evolved twice during
the mid-Cenozoic, once in the Neotropics and once in the Afrotropics,
fossil army ants are markedly scarce, comprising a single known species
from the Caribbean 16 Ma. Here we report the oldest army ant fossil and
the first from the Eastern Hemisphere (EH), Dissimulodorylus perseus,
preserved in Baltic amber dated to the Eocene. Using a combined
morphological and molecular Ultra Conserved Elements dataset spanning
doryline lineages, we find that D. perseus is nested among extant EH army
ants with affinities to Dorylus “driver ants.” Army ants are characterized
by limited extant diversification throughout most of the Cenozoic; the
discovery of D. perseus suggests an unexpected diversity of now-extinct
army ant lineages in the Cenozoic, some of which were present in
Continental Europe.
