Fossil Ants (Hymenoptera: Formicidae): Ancient Diversity and the Rise of Modern Lineages
Myrmecological News 24 1-30 Vienna, March 2017 Fossil ants (Hymenoptera: Formicidae): ancient diversity and the rise of modern lineages Phillip BARDEN Abstract The ant fossil record is summarized with special reference to the earliest ants, first occurrences of modern lineages, and the utility of paleontological data in reconstructing evolutionary history. During the Cretaceous, from approximately 100 to 78 million years ago, only two species are definitively assignable to extant subfamilies – all putative crown group ants from this period are discussed. Among the earliest ants known are unexpectedly diverse and highly social stem- group lineages, however these stem ants do not persist into the Cenozoic. Following the Cretaceous-Paleogene boun- dary, all well preserved ants are assignable to crown Formicidae; the appearance of crown ants in the fossil record is summarized at the subfamilial and generic level. Generally, the taxonomic composition of Cenozoic ant fossil communi- ties mirrors Recent ecosystems with the "big four" subfamilies Dolichoderinae, Formicinae, Myrmicinae, and Ponerinae comprising most faunal abundance. As reviewed by other authors, ants increase in abundance dramatically from the Eocene through the Miocene. Proximate drivers relating to the "rise of the ants" are discussed, as the majority of this increase is due to a handful of highly dominant species. In addition, instances of congruence and conflict with molecular- based divergence estimates are noted, and distinct "ghost" lineages are interpreted. The ant fossil record is a valuable resource comparable to other groups with extensive fossil species: There are approximately as many described fossil ant species as there are fossil dinosaurs. The incorporation of paleontological data into neontological inquiries can only seek to improve the accuracy and scale of generated hypotheses.

E-mail: [email protected], [email protected] Abstract A new genus of ants, Zigrasimecia Barden and Grimaldi, is described for a new and uniquely specialized species, Z. ton- sora Barden and Grimaldi n.sp., preserved in Cretaceous amber from Myanmar. The amber is radiometrically dated at 99 myo. Zigrasimecia is closely related to another basal genus of ants known only in Burmese and French Cretaceous amber, Sphecomyrmodes Engel and Grimaldi, based in part on the shared possession of a comb of pegs on the clypeal margin, as well as mandible structure. Highly specialized features of Zigrasimecia include extensive development of the clypeal comb, a thick brush of setae on the oral surface of the mandibles and on the labrum, and a head that is broad, flattened, and which bears a crown of blackened, rugose cuticle. Mouthparts are hypothesized to have functioned in a unique man- ner, showing no clear signs of dentition representative of “chewing” or otherwise processing solid food. Although all ants in Burmese amber are basal, stem-group taxa, there is an unexpected diversity of mouthpart morphologies and probable feeding modes.

The Rise of the Ants: a Phylogenetic and Ecological Explanation

Wilson, March 18, 2005 In the past two decades, studies of anatomy, behavior, and, most recently, DNA sequences have clarified the phylogeny of the ants at the subfamily and generic levels. In addition, a rich new harvest of Cretaceous and Paleogene fossils has helped to date the major evolutionary radiations. We collate this information and then add data from the natural history of the modern fauna to sketch a his- tory of major ecological adaptations at the subfamily level. The key events appear to have been, first, a mid-Cretaceous initial radia- tion in forest ground litter and soil coincident with the rise of the angiosperms (flowering plants), then a Paleogene advance to eco- logical dominance in concert with that of the angiosperms in tropical forests, and, finally, an expansion of some of the lineages, aided by changes in diet away from dependence on predation, upward into the canopy, and outward into more xeric environments. ecology ͉ evolution ͉ phylogeny ͉ sociobiology umanity lives in a world recently divided (4), comprising the myrmine and more derivative traits.
