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. -

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. -

Queens are apterous and dichthadiigynes. Males have wings and eyes. Their lifestyles remain virtually unknown. The Western Mediterranean region hosts a high diversity, with 9 species in north Africa and 5 in the Iberian Peninsula. Recent sampling in Central Spain (Tortuero, Guadalajara province) led to the discovery of a colony of a large-sized Leptanilla species. This population can be assigned to L. plutonia, a species known from a single worker (the holotype) until now, easily distinguished from other Iberian species by its large size. These specimens allowed for a redescription of the species, also giving the first insights into its intraspecific variability and morphological structures not mentioned in the original description, such as the presence of a secondary labrum, large apodemes in the postpetiole or a promesosternal keel, among others. -

The behavior of the queen and workers in the amblyoponine ant Prionopelta krae pelini was observed and compared with th at of the queen and workers of P. amabilis.

This species has very special behavioral and morphological characteri tics: queens feed onl y on trophic eggs laid by workers, the pu pal chamber shows « wall papering » of the surface with cocoon fragments, and workers show recruitment of nestmates for prey retrieval by using a trail pheromone which originates from special basità.rsal glands in the hindlegs (HëJLLDOBLER & WILSON, 1986; HbLLDOBLER et al., 1992). -

It is found in two islands in the Mediterranean Sea, North Africa, India, Ceylon, Malaya, Java and in the southwest of Australia. Not a single species of the subfamily has hitherto been discovered in China or Japan. To my surprise one species of the genus Leptanilla was recently found on Mt. Hiko, Kyushu, Japan, by Messrs. K. Morimoto and R. Morimoto. This species represents a new, and the thirteenth, species of the genus, very different from any other known member of the group. The occurrence of the subfamily in Japan suggests that the ants of this group originated in Tropical India and from this original center long ago dispersed in three directions. Before going further I gratefully acknowledge Dr. William L. Brown, Jr., of the Museum of Comparative Zoiilogy at Harvard College for his kind help in the preparation of this paper. I appreciate very much the help of Mr. R. Ishikawa, who has been cooperative in copying the original descriptions of Forel’s LeptaniZZa species. I also wish to thank Messrs. R. Morimoto and K. Morimoto for their efforts in finding such a rare and interesting species of LeptaniZZa in Japan. -
Integrative Biodiversity Inventory of Ants from a Sicilian Archipelago Reveals High Diversity on Young Volcanic Islands (Hymenoptera: Formicidae)
Organisms Diversity & Evolution https://doi.org/10.1007/s13127-020-00442-3 ORIGINAL ARTICLE Integrative biodiversity inventory of ants from a Sicilian archipelago reveals high diversity on young volcanic islands (Hymenoptera: Formicidae) Sämi Schär1 & Mattia Menchetti1,2 & Enrico Schifani3 & Joan Carles Hinojosa1 & Leonardo Platania1 & Leonardo Dapporto2 & Roger Vila1 Received: 23 November 2019 /Accepted: 11 May 2020 # Gesellschaft für Biologische Systematik 2020 Abstract Islands are fascinating study systems for biogeography, allowing researchers to investigate patterns across organisms on a comparable geographical scale. They are also often important for conservation. Here, we present the first bio-inventory of the ant fauna of the Aeolian Islands, a Sicilian volcanic archipelago formed within the last million years. We documented a total of 40 species, including one first record for Italy (Lasius casevitzi). Mitochondrial DNA barcodes were obtained for all 40 taxa sampled on the islands, 13 of which were studied genetically for the first time. Mitochondrial DNA sequences of island specimens were compared with those of conspecific samples from other Aeolian Islands, Sicily and mainland Italy. Standardized photographical documentation of all sequenced specimens is provided. All but one currently recognized species (97.5%) were recovered as monophyletic. Genetic divergence within species ranged up to 12.4% in Pheidole pallidula, although most species had much lower levels of intraspecific divergence. At the scale of the Aeolian Islands, intraspecific genetic divergence varied significantly between subfamilies, with species of the subfamily Myrmicinae showing higher intraspecific divergences than the Formicinae. Comparison of specimens from the Aeolian Islands with conspecific ones from the putative source populations (Sicily and mainland Italy) suggested that the island of Panarea has the genetically most derived myrmeco-fauna among the seven focal Islands.
