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

  title={Rediscovery of the Bizarre Cretaceous Ant Haidomyrmex Dlussky (Hymenoptera: Formicidae), with Two New Species},
  author={Phillip Barden and David A. Grimaldi},
ABSTRACT The discovery of two distinct, near-complete specimens belonging to the Cretaceous ant genus Haidomyrmex Dlussky prompts a detailed description and discussion of a remarkable mandibular morphology. The specimens, preserved in 98 million-year-old amber from northern Myanmar, are described here as Haidomyrmex scimitarus, n. sp., and Haidomyrmex zigrasi, n. sp., with diagnostic differences provided between them as well as with H. cerberus Dlussky (also in Burmese amber). Relationships and… 

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.

A remarkable diversity of new nonempidoid orthorrhaphan flies from the mid-Cretaceous of Myanmar is presented, including 28 species in 22 genera (13 new), and at least 12 families, and some morphological features in fossil and Recent Brachycera are presented.

Two new iron maiden ants from Burmese amber (Hymenoptera: Formicidae: †Zigrasimeciini)

Two new species from Burmese amber based on workers are described and a contribution to a better understanding of the Mesozoic Formicidae is made and diversity for the phylogeny of the family is documents.

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.

Ants of the genus Protalaridris (Hymenoptera: Formicidae), more than just deadly mandibles

The ants of the genus Protalaridris are revised based upon their morphology, suggesting they are sit-and-wait ambush predators that open their jaws to approximately 180° when stalking and comparing the mandibular morphology of long-mandibulate ProtalARidris with other extant and extinct ants bearing elongate, dorsoanterior arching mandibles suggests the supposedmandibular apex is actually a hypertrophied, preapical tooth.

Distal leg structures of the Aculeata (Hymenoptera): A comparative evolutionary study of Sceliphron (Sphecidae) and Formica (Formicidae)

The distal parts of the legs of Sceliphron caementarium and Formica rufa are documented and discussed with respect to phylogenetic and functional aspects, mainly linked with two functional syndromes, walking efficiently on different substrates and cleaning the body surface.

† Camelosphecia gen. nov., lost ant-wasp intermediates from the mid-Cretaceous (Hymenoptera, Formicoidea)

Fossils provide primary material evidence for the pattern and timing of evolution and the first comprehensive key to the major groupings of Mesozoic Formicoidea is provided, alongside a synoptic classification in which †Zigrasimeciinaestat.



New fossil ants in French Cretaceous amber (Hymenoptera: Formicidae)

A new sphecomyrmine ant, allied to the Burmese amber genus Haidomyrmex, is described from mid-Cretaceous amber of France and the diagnosis of the tribe HaidOMyrmecini is emended based on the new type material, which includes a gyne (alate female) and two incomplete workers.

The apex of the gaster has an acidopore and, thus, allows definitive assignment of the fossil to the large extant subfamily Formicinae, members of which use a defensive spray of formic acid.

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.

Fossil evidence for the early ant evolution

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.

The remarkable discovery of a worker ant preserved in amber for over 90 million years that is clearly assignable to a modern ant subfamily that contains many familiar extant species, including carpenter ants strongly indicates that the diversification of many ant subfamilies occurred earlier and more rapidly than previously suspected.

Phylogeny of the Ants: Diversification in the Age of Angiosperms

Divergence time estimates calibrated by minimum age constraints from 43 fossils indicate that most of the subfamilies representing extant ants arose much earlier than previously proposed but only began to diversify during the Late Cretaceous to Early Eocene, which also witnessed the rise of angiosperms and most herbivorous insects.

Evaluating alternative hypotheses for the early evolution and diversification of ants

The largest ant molecular phylogenetic data set published to date is generated, containing ≈6 kb of DNA sequence from 162 species representing all 20 ant subfamilies and 10 aculeate outgroup families, and casts strong doubt on the existence of a poneroid clade as currently defined.
