  • 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] Abstract The formicid genus Gesomyrmex is reviewed and several new species are described from the middle Eocene (about 47 Ma) of Grube Messel, Germany, and from the middle Eocene (about 43 Ma) of Eckfeld maar, Germany. The new taxa are Gesomyrmex curiosus n. sp., Gesomyrmex breviceps n. sp., and Gesomyrmex pulcher n. sp. from Messel, and Gesomyrmex flavescens n. sp., and Gesomyrmex germanicus n. sp. from Eckfeld maar. Two previosly described Oligocene species must be excluded from Gesomyrmex. Former G. expectans Théobald, 1937 is transferred to Eoformica expectans (Théobald, 1937) (comb. nov.), and former G. mi egi Théobald, 1937 has to be considered as Formicidae incertae sedis (comb. nov.). A key to the living and fossil reproductive female caste (gyne) of the genus Gesomyrmex is provided. Given the fossil records of Gesomyrmex hoernesi Mayr, 1868 from different European amber deposits the presence of this genus in Europe during the Eocene is well established.

Wedmannb aDepartment of Evolution, Biological Faculty, M.V.Lomonosov Moscow State University, Vorobjovy gory, 119992, Moscow, Russia; bForschungsstation Grube Messel, Senckenberg Forschungsinstitut und Naturmuseum, Markstraße 35, D-64409, Messel, Germany (Received 17 September 2010; accepted 27 March 2011; printed 5 December 2012) Ants are a very successful group among insects, but the course of evolution of their biodiversity is still unclear. This study sheds light on ant diversification during the Eocene. Analysis of the ant taphocoenosis of the fossil site Grube Messel, Germany (47 Ma) yielded three poneromorph subfamilies and 22 new species in six genera, four of which are new: Pseudectatomma gen. nov., Cephalopone gen. nov., Cyrtopone gen. nov. and Messelepone gen. nov. Only one extant genus, Pachycondyla, is present in the taphocoenosis from Messel. The high diversity of poneromorph ants from Messel is very striking in comparison with middle to late Eocene European ambers. A significantly lower proportion of species in ambers can be assigned to poneromorph ants, and fewer poneromorph species are known from European ambers than from Messel. A possible gradual decline of the diversity of poneromorphs from the Eocene to the Miocene seems to be detectable worldwide. These insights are discussed in the context of the morphology and ecology of Poneromorpha and Formicomorpha. The proportion of ant castes in amber seems to indicate that already during the Eocene poneromorphs inhabited preferably litter and soil, whereas formicomorphs preferred the arboreal realm.

The conflicting views of Rovno amber being allochthonous, having been trans- ported to the Pripyat area during the Eocene from the north across the sea and thus deriv- ing from the same region as Baltic amber versus suggested local origins within the Ukrainian Crystalline Shield must have been tested by a comparison of inclusions of the Rovno and other ambers.

Journal of Hymenoptera Research 82: 237–251. https://doi.org/10.3897/ jhr.82.64599 Abstract A new species, Formica ribbeckei Radchenko & Perkovsky, sp. nov., is described based on four workers from late Eocene Rovno amber (Ukraine). It most resembles F. flori Mayr, 1868 but differs from the latter mainly by the 5-segmented maxillary palps with the preapical segment subequal in length to the apical one, and by the shorter first funicular segment. Fossil F. luteola Presl, 1822, F. trigona Presl, 1822, F. mac- rognatha Presl, 1822 and F. quadrata Holl, 1829 are considered incertae sedis in Formicidae. Thus, ten valid Formica Linnaeus, 1758 species (including F. ribbeckei) are known now from late Eocene European ambers. The diversity of Formica in the early and middle Eocene deposits of Eurasia and North America is considered. It is assumed that the genus Formica most likely arose in the early Eocene.

The tax- onomic composition and relative species abundances of species in representative collections are analyzed and considerable differences between the above four types of amber are shown. These differences appear to reflect differences in ecological conditions rather than in age. The Baltic and Bitterfeld ant assemblages are shown to be most similar, the Scandinavian assemblage turns out to be most dissimilar to these, and the Rovno assem- blage is shown to be intermediate.

Conclusion Online posting date: 15th May 2013 Since their appearance during the Cretaceous, ants have approximately 12 500 species of ants, all eusocial, have diversified to become today the most diverse group of been described and hundreds of new species are described social insects and one of the most influential groups of each year. Ant biologists estimate that the Formicidae organisms on the planet. More than 12 500 species of ants family could include no less than 20 000 species (Ho¨lldobler and Wilson, 1990). In comparison, there are ‘only’ are presently described, distributed within 21 sub- approximately 3000 termite species (Engel et al., 2009), families, with a large majority of the species belonging to 2000 species of social bees (8% of the total bees) and 1100 only four subfamilies.
