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. -

October 14, 2019 Ant microbial endosymbionts and the emergent properties of social groups Alessio Sclocco1, Shirlyn Jia Yun Ong2 and Serafino Teseo2† 1Netherlands eScience Center, Amsterdam, The Netherlands (E-mail: [email protected]) 2School of Biological Sciences, Nanyang Technological University, Singapore (Tel: +65 63167088; E-mail: [email protected]) Abstract: In the last fifteen years, research on animal models has provided advances on how gut symbiotic microbes affect behavior and its underlying neurophysiology. However, most studies on the gut microbiota only take into exam individual behavior without considering social dynamics. Contrarily, animals and humans live in complex societies where they constantly adjust physiology and behavior to social interactions. To improve our understanding of how microbes and hosts interact and produce functional individual, social and collective phenotypes, we need to broaden our experimental approaches to a group-level dimension. The ideal models for this purpose are social animals living in stable symbioses with microbes, such as eusocial insects. In our research, we investigate Camponotus carpenter ants and their obligate bacterial symbiont Blochmannia from a behavioral ecology perspective. We aim to create ant colonies including differential proportions of bacteria-free individuals by suppressing Blochmannia with antibiotics. Then, using a machine learning-based video tracking system, we will study network features and group-level behavior of such experimental colonies.

American Museum Novitates
AMERICAN MUSEUM NOVITATES Number 3823, 80 pp. January 16, 2015 Diverse new scale insects (Hemiptera: Coccoidea) in amber from the Cretaceous and Eocene with a phylogenetic framework for fossil Coccoidea ISABELLE M. VEA1, 2 AND DAVID A. GRIMALDI2 ABSTRACT Coccoids are abundant and diverse in most amber deposits around the world, but largely as macropterous males. Based on a study of male coccoids in Lebanese amber (Early Cretaceous), Burmese amber (Albian-Cenomanian), Cambay amber from western India (Early Eocene), and Baltic amber (mid-Eocene), 16 new species, 11 new genera, and three new families are added to the coccoid fossil record: Apticoccidae, n. fam., based on Apticoccus Koteja and Azar, and includ- ing two new species A. fortis, n. sp., and A. longitenuis, n. sp.; the monotypic family Hodgsonicoc- cidae, n. fam., including Hodgsonicoccus patefactus, n. gen., n. sp.; Kozariidae, n. fam., including Kozarius achronus, n. gen., n. sp., and K. perpetuus, n. sp.; the irst occurrence of a Coccidae in Burmese amber, Rosahendersonia prisca, n. gen., n. sp.; the irst fossil record of a Margarodidae sensu stricto, Heteromargarodes hukamsinghi, n. sp.; a peculiar Diaspididae in Indian amber, Nor- markicoccus cambayae, n. gen., n. sp.; a Pityococcidae from Baltic amber, Pityococcus monilifor- malis, n. sp., two Pseudococcidae in Lebanese and Burmese ambers, Williamsicoccus megalops, n. gen., n. sp., and Gilderius eukrinops, n. gen., n. sp.; an Early Cretaceous Weitschatidae, Pseudo- weitschatus audebertis, n. gen., n. sp.; four genera considered incertae sedis, Alacrena peculiaris, n. gen., n. sp., Magnilens glaesaria, n. gen., n. sp., and Pedicellicoccus marginatus, n. gen., n. sp., and Xiphos vani, n. -
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. -
Cytogenetic Studies of the Neotropical Ant Genus Ectatomma (Formicidae: Ectatomminae: Ectatommini) by Luísa Antônia Campos Barros1; Cléa S.F
555 Cytogenetic Studies of the Neotropical Ant Genus Ectatomma (Formicidae: Ectatomminae: Ectatommini) by Luísa Antônia Campos Barros1; Cléa S.F. Mariano2; Davileide de Sousa Borges2; Silvia G. Pompolo1 & Jacques H.C. Delabie2* AbsTRacT The ant genus Ectatomma (Hymenoptera: Formicidae) is typically Neo- tropical and is the only genus of the subfamily Ectatomminae for which no cytogenetic data previously existed. Cytogenetic studies of five species of the Ectatomma genus are reported here. Colonies were collected at Viçosa (Minas Gerais, Brazil), Ilhéus and Manoel Vitorino (Bahia, Brazil). In this genus, the chromosome number ranged from 2n=36 to 46: Ectatomma brunneum Smith, 2n=44 (karyotype formula: 2K=22M + 22A); Ectatomma muticum Mayr, n=20 (K=16M + 4A); Ectatomma permagnum Forel, 2n=46 (2K=20M + 26A); Ectatomma tuberculatum Olivier, 2n=36 (2K=30M + 6A), while the observed metaphases of Ectatomma edentatum Roger, with 2n=46, did not allow a precise karyotype definition. The variations presented by the karyotypes of these ants can be attributed to the increase in the number of acrocentric chromosomes, probably because of rearrangements such as centric fission. This study is important for the understanding of evolutionary processes in the Ectatomminae subfamily. Key-words: chromosome, karyotype, Minimum Interaction Theory INTRODUCTION Many animal studies have proven that cytogenetics is a useful tool for the biological understanding of a species, especially in evolutionary, taxonomic, phylogenetic and speciation mechanism studies, because chromosome al- terations are normally significant for species evolution (White 1973; King 1Laboratório de Citogenética de Insetos.

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. -

However, burning has been gradually eliminated with the relatively recent use of mechanical harvesting. This will result in significant changes in the agroecosystem, as the straw will remain in the field. No investigation on Formicidae found in sugarcane plantations in Southeastern Brazil harvested by this new system has been done yet. Because of their feeding habits, many species of this family may act as predators of several sugarcane pests. In this study, the sampling efficacy of pitfall traps, baits, and underground traps with two types of attractants were evaluated. Pitfall traps gave the largest richness, while abundance was the highest from baiting. Community composition and structure differed in relation to the sampling methods used. -

En esta tesis se estudiaron de forma integral la sistemática y ecología de una subfamilia de hormigas, las ponerinas. Esta subfamilia predomina en regiones tropicales y neotropicales, estando presente en Argentina desde el norte hasta la provincia de Buenos Aires. Se utilizó un enfoque integrador, combinando análisis genéticos con morfológicos para estudiar su diversidad, en combinación con estudios ecológicos y comportamentales para estudiar la dominancia, estructura de la comunidad y posición trófica de las Ponerinas. Los resultados sugieren que la diversidad es más alta de lo que se creía, tanto por que se encontraron nuevos registros durante la colecta de nuevo material, como porque nuestros análisis sugieren la presencia de especies crípticas. Adicionalmente, demostramos que en el PN Iguazú, dos ponerinas: Dinoponera australis y Pachycondyla striata son componentes dominantes en la comunidad de hormigas. Análisis de isótopos estables revelaron que la mayoría de las Ponerinas ocupan niveles tróficos altos, con excepción de algunas especies arborícolas del género Neoponera que dependerían de néctar u otros recursos vegetales.
