Newly Discovered Sister Lineage Sheds Light on Early Ant Evolution
Newly discovered sister lineage sheds light on early ant evolution Christian Rabeling†‡§, Jeremy M. Brown†¶, and Manfred Verhaagh‡ †Section of Integrative Biology, and ¶Center for Computational Biology and Bioinformatics, University of Texas, 1 University Station C0930, Austin, TX 78712; and ‡Staatliches Museum fu¨r Naturkunde Karlsruhe, Erbprinzenstr. 13, D-76133 Karlsruhe, Germany Edited by Bert Ho¨lldobler, Arizona State University, Tempe, AZ, and approved August 4, 2008 (received for review June 27, 2008) Ants are the world’s most conspicuous and important eusocial insects and their diversity, abundance, and extreme behavioral specializations make them a model system for several disciplines within the biological sciences. Here, we report the discovery of a new ant that appears to represent the sister lineage to all extant ants (Hymenoptera: Formicidae). The phylogenetic position of this cryptic predator from the soils of the Amazon rainforest was inferred from several nuclear genes, sequenced from a single leg. Martialis heureka (gen. et sp. nov.) also constitutes the sole representative of a new, morphologically distinct subfamily of ants, the Martialinae (subfam. nov.). Our analyses have reduced the likelihood of long-branch attraction artifacts that have trou- bled previous phylogenetic studies of early-diverging ants and therefore solidify the emerging view that the most basal extant ant lineages are cryptic, hypogaeic foragers. On the basis of morpho- logical and phylogenetic evidence we suggest that these special- EVOLUTION ized subterranean predators are the sole surviving representatives of a highly divergent lineage that arose near the dawn of ant diversification and have persisted in ecologically stable environ- ments like tropical soils over great spans of time. -

Digging Deeper Into the Ecology of Subterranean Ants: Diversity and Niche Partitioning Across Two Continents
diversity Article Digging Deeper into the Ecology of Subterranean Ants: Diversity and Niche Partitioning across Two Continents Mickal Houadria * and Florian Menzel Institute of Organismic and Molecular Evolution, Johannes-Gutenberg-University Mainz, Hanns-Dieter-Hüsch-Weg 15, 55128 Mainz, Germany; [email protected] * Correspondence: [email protected] Abstract: Soil fauna is generally understudied compared to above-ground arthropods, and ants are no exception. Here, we compared a primary and a secondary forest each on two continents using four different sampling methods. Winkler sampling, pitfalls, and four types of above- and below-ground baits (dead, crushed insects; melezitose; living termites; living mealworms/grasshoppers) were applied on four plots (4 × 4 grid points) on each site. Although less diverse than Winkler samples and pitfalls, subterranean baits provided a remarkable ant community. Our baiting system provided a large dataset to systematically quantify strata and dietary specialisation in tropical rainforest ants. Compared to above-ground baits, 10–28% of the species at subterranean baits were overall more common (or unique to) below ground, indicating a fauna that was truly specialised to this stratum. Species turnover was particularly high in the primary forests, both concerning above-ground and subterranean baits and between grid points within a site. This suggests that secondary forests are more impoverished, especially concerning their subterranean fauna. Although subterranean ants rarely displayed specific preferences for a bait type, they were in general more specialised than above-ground ants; this was true for entire communities, but also for the same species if they foraged in both strata.

Myrmecological News 19 61-64 Vienna, January 2014 A novel intramandibular gland in the ant Tatuidris tatusia (Hymenoptera: Formicidae) Johan BILLEN & Thibaut DELSINNE Abstract The mandibles of Tatuidris tatusia workers are completely filled with glandular cells that represent a novel kind of intra- mandibular gland that has not been found in ants so far. Whereas the known intramandibular glands in ants are either epi- thelial glands of class-1, or scattered class-3 cells that open through equally scattered pores on the mandibular surface, the ducts of the numerous class-3 secretory cells of Tatuidris all converge to open through a conspicuous sieve plate at the proximal ventral side near the inner margin of each mandible.

The Functions and Evolution of Social Fluid Exchange in Ant Colonies (Hymenoptera: Formicidae) Marie-Pierre Meurville & Adria C
ISSN 1997-3500 Myrmecological News myrmecologicalnews.org Myrmecol. News 31: 1-30 doi: 10.25849/myrmecol.news_031:001 13 January 2021 Review Article Trophallaxis: the functions and evolution of social fluid exchange in ant colonies (Hymenoptera: Formicidae) Marie-Pierre Meurville & Adria C. LeBoeuf Abstract Trophallaxis is a complex social fluid exchange emblematic of social insects and of ants in particular. Trophallaxis behaviors are present in approximately half of all ant genera, distributed over 11 subfamilies. Across biological life, intra- and inter-species exchanged fluids tend to occur in only the most fitness-relevant behavioral contexts, typically transmitting endogenously produced molecules adapted to exert influence on the receiver’s physiology or behavior. Despite this, many aspects of trophallaxis remain poorly understood, such as the prevalence of the different forms of trophallaxis, the components transmitted, their roles in colony physiology and how these behaviors have evolved. With this review, we define the forms of trophallaxis observed in ants and bring together current knowledge on the mechanics of trophallaxis, the contents of the fluids transmitted, the contexts in which trophallaxis occurs and the roles these behaviors play in colony life. We identify six contexts where trophallaxis occurs: nourishment, short- and long-term decision making, immune defense, social maintenance, aggression, and inoculation and maintenance of the gut microbiota. Though many ideas have been put forth on the evolution of trophallaxis, our analyses support the idea that stomodeal trophallaxis has become a fixed aspect of colony life primarily in species that drink liquid food and, further, that the adoption of this behavior was key for some lineages in establishing ecological dominance. -
THE TRUE ARMY ANTS of the INDO-AUSTRALIAN AREA (Hymenoptera: Formicidae: Dorylinae)
Pacific Insects 6 (3) : 427483 November 10, 1964 THE TRUE ARMY ANTS OF THE INDO-AUSTRALIAN AREA (Hymenoptera: Formicidae: Dorylinae) By Edward O. Wilson BIOLOGICAL LABORATORIES, HARVARD UNIVERSITY, CAMBRIDGE, MASS., U. S. A. Abstract: All of the known Indo-Australian species of Dorylinae, 4 in Dorylus and 34 in Aenictus, are included in this revision. Eight of the Aenictus species are described as new: artipus, chapmani, doryloides, exilis, huonicus, nganduensis, philiporum and schneirlai. Phylo genetic and numerical analyses resulted in the discarding of two extant subgenera of Aenictus (Typhlatta and Paraenictus) and the loose clustering of the species into 5 informal " groups" within the unified genus Aenictus. A consistency test for phylogenetic characters is discussed. The African and Indo-Australian doryline species are compared, and available information in the biology of the Indo-Australian species is summarized. The " true " army ants are defined here as equivalent to the subfamily Dorylinae. Not included are species of Ponerinae which have developed legionary behavior independently (see Wilson, E. O., 1958, Evolution 12: 24-31) or the subfamily Leptanillinae, which is very distinct and may be independent in origin. The Dorylinae are not as well developed in the Indo-Australian area as in Africa and the New World tropics. Dorylus itself, which includes the famous driver ants, is centered in Africa and sends only four species into tropical Asia. Of these, the most widespread reaches only to Java and the Celebes. Aenictus, on the other hand, is at least as strongly developed in tropical Asia and New Guinea as it is in Africa, with 34 species being known from the former regions and only about 15 from Africa. -

Nguyen, & Katsuyuki Eguchi Abstract The monotypic genus Opamyrma Yamane, Bui & Eguchi, 2008 (Hymeno ptera, Formicidae, Leptanillinae) is an ex- tremely rare relictual lineage of apparently subterranean ants, so far known only from a few specimens of the worker and queen from Ha Tinh in Vietnam and Hainan in China. The phylogenetic position of the genus had been uncertain until recent molecular phylogenetic studies strongly supported the genus to be the most basal lineage in the cryptic subterranean subfamily Leptanillinae. In the present study, we examine the morphology of the worker, queen, male, and larva of the only species in the genus, Opamyrma hungvuong Yamane, Bui & Eguchi, 2008, based on colonies newly collected from Guangxi in China and Son La in Vietnam, and provide descriptions and illustrations of the male, larva, and some body parts of the worker and queen (including mouthparts, tentorium, and sting apparatus) for the first time. The novel morphological data, particularly from the male, larva, and sting apparatus, support the current phylogenetic position of the genus as the most basal leptanilline lineage. Moreover, we suggest that the loss of lancet valves in the fully functional sting apparatus with accompanying shift of the venom ejecting mechanism may be a non-homoplastic synapomorphy for the Leptanillinae within the Formicidae. -
