Recent studies on the ant phylogeny are mainly based on the molecular analyses of extant subfamilies and do not include the extinct, only Cretaceous subfamily Sphecomyrminae. However, the latter is of major importance for ant relationships, as it is considered the most basal subfamily. Therefore, each new discovery of a Mesozoic ant is of high interest for improving our understanding of their early history and basal relationships. In this paper, a new sphecomyrmine ant, allied to the Burmese… 

A new species of Baikuris (Hymenoptera: Formicidae: Sphecomyrminae) in mid-Cretaceous amber from France

A fourth species of Baikuris is described, based on a malefrom latest Albianeearliest Cenomanian amber of southwestern France, known as Charentese amber, which is distinguished from other species notably by its larger size, itsforewing with vein 2MþCu absent and vein 3Cu tubular, and the presence of a subpetiolar process.

A new trap-jawed ant (Hymenoptera: Formicidae: Haidomyrmecini) from Canadian Late Cretaceous amber

Morphological features of H. cippus, such as the presence of an elongate antennomere II (pedicel), further support the argument that Haidomyrmecini may not actually belong within the subfamily Sphecomyrminae, and may warrant recognition at the sub family level or inclusion as a highly autapomorphic clade within another subfamily.

A new genus of highly specialized ants in Cretaceous Burmese amber (Hymenoptera: Formicidae).

Mouthparts are hypothesized to have functioned in a unique manner, showing no clear signs of dentition representative of "chewing" or otherwise processing solid food, there is an unexpected diversity of mouthpart morphologies and probable feeding modes.

Rediscovery of the Bizarre Cretaceous Ant Haidomyrmex Dlussky (Hymenoptera: Formicidae), with Two New Species

Mandibles appear to have moved in a plane oblique to the dorsoventral and horizontal axes of the body, unlike the lateral-plane movement of modern ants, providing insight into some of the earliest yet surprisingly specialized ants that roamed the Earth.

The first fossil record of Polyrhachis (Hymenoptera: Formicidae: Formicinae) from the Upper Miocene of Crete (Greece)

Interestingly, the abundance of Polyrhachis in Indonesian copal confirms the statement that their absence in Baltic amber is not casual, and closely related genera are quite diverse in Tertiary amber deposits.

Fossil ants (Hymenoptera: Formicidae): ancient diversity and the rise of modern lineages

The ant fossil record is summarized with special re ference to the earliest ants, first occurrences of modern lineages, and the utility of paleontological data in reconstructi ng evolutionary

The poneromorph ants (Hymenoptera, Formicidae: Amblyoponinae, Ectatomminae, Ponerinae) of Grube Messel, Germany: high biodiversity in the Eocene

Light is shed on ant diversification during the Eocene by analysis of the ant taphocoenosis of the fossil site Grube Messel, Germany, which yielded three poneromorph subfamilies and 22 new species in six genera, four of which are new.

A Diverse Ant Fauna from the Mid-Cretaceous of Myanmar (Hymenoptera: Formicidae)

A new collection of 24 wingless ant specimens from mid-Cretaceous Burmese amber comprises nine new species belonging to the genus Sphecomyrmodes Engel and Grimaldi, representing the largest known diversification of closely related Cretaceous ants with respect to species number.

New and rediscovered primitive ants (Hymenoptera: Formicidae) in Cretaceous amber from New Jersey, and their phylogenetic relationships

Discovery of new and exclusively primitive ants in upper Cretaceous ambers indicates an origin of the ants probably in the lowermost Cret Jurassic, but no older, contrary to a recent molecular hypothesis.

Primitive New Ants in Cretaceous Amber from Myanmar, New Jersey, and Canada (Hymenoptera: Formicidae)

From Burmese amber are the oldest, definitive ants, along with ones in amber from Charente-Maritime of France (approximately contemporaneous in age), and a new genus and species, allied to †Sphecomyrma, is described from these deposits.

The internal phylogeny of ants (Hymenoptera: Formicidae)

A reconstruction of the ground plan of the Formicidae indicated that the most specialized of all recent ants are the members of the subfamily Dorylinae and the least specialized ones are the monotypic Apomyrminae.

Phylogeny and biogeography of the ant subfamily Myrmeciinae (Hymenoptera: Formicidae)

The myrmeciine ants appear to be a formerly widespread group that retained many ancestral formicid characteristics and that became extinct everywhere except in the Australian region, supporting the contention that many of the major lineages of ants arose at around the same time during a bout of diversification in the middle or late Cretaceous.

This palaeoenvironmental reconstruction supports an initial radiation of ants in forest ground litter coincident with the rise of angiosperms, as recently proposed as an ecological explanation for their origin and successful evolution.
