New species of the fossil ant genus Drymomyrmex (Hymenoptera, Formicidae, Formicinae) from the late Eocene Rovno amber (Ukraine)

open access: yesPalaeoentomology, 2021
A new species of the fossil ant genus Drymomyrmex Wheeler, 1915, D. rasnitsyni sp. nov., is described from the late Eocene Rovno amber (Ukraine). This is the first find of a worker of this genus and the first record of Drymomyrmex in the Rovno amber ...

The Thai species of the Polyrhachis (Myrmatopa) flavicornis Smith, 1857 species group, with description of a new species (Hymenoptera, Formicidae, Formicinae).

open access: yesZootaxa, 2023
The Polyrhachis (Myrmatopa) flavicornis species group in Thailand is reviewed. Four species are recognized, of which one species closely related to Polyrhachis constructor Smith, 1857 is described and illustrated as new to science based on the worker ...

Terminal Filament Bundling Underlies the Development of Ovariole Number Dimorphism Between Queen and Worker Ants. [PDF]

open access: yesEvol Dev
We trace the formation of the cell structures known to determine ovariole number in the model insect Drosophila melanogaster, called terminal filaments. By investigating the formation of terminal filaments and ovarioles during queen and worker development in ants, we confirm the existence of terminal filament bundling (white arrows) and show that it ...

Effect of Time-Since-Fire on Ant Communities in a Semi-Arid Landscape. [PDF]

open access: yesEcol Evol
We sampled ants from five sites with varying fire histories (3, 5, 9, 26, and 34 years since the last fire). A total of 16,360 ants were collected, and 59 species across 20 genera were identified. Our results indicate that total ant abundance was higher in recently burnt sites and decreased with increasing time‐since‐fire, while ant species richness ...

Neotropical ants are at greater risk from global warming in savanna than in adjacent forest. [PDF]

open access: yesEcology
Abstract Determining how the thermal tolerances of species are related to climatic conditions at multiple spatial scales can improve our understanding of species distributions and their vulnerability to climate change. We compare the warming tolerances—a metric of warming vulnerability—of arboreal and ground‐dwelling ants from savanna and adjacent ...

The predatory behavior of ants: an impressive panoply of morphological adaptations. [PDF]

open access: yesInsect Sci
This review focuses on predation in ants, showing the wide diversity of cases from solitary foraging to group hunting tactics, as well as the evolution of mandible shape frequently adapted to capture specific prey. Although most ants are generalist feeders, finding their sugary substances directly on plants or indirectly via sap‐sucking insects, some ...

Molecular Phylogeny of the Ant Subfamily Formicinae (Hymenoptera, Formicidae) from China Based on Mitochondrial Genes [PDF]

open access: yesSociobiology, 2013
To resolve long-standing discrepancies in the relationships among genera within the ant subfamily Formicinae, a phylogenetic study of Chinese Formicine ants based on three mitochondria genes (Cyt b, COI, COII) was conducted.

Pollination of Richea dracophylla (Ericaceae) and the role of the nocturnal ant Notoncus hickmani (Formicinae)

open access: yesAustral ecology (Print), 2023
Our observation of large numbers of ants Notoncus hickmani (Formicinae) on the flowers of a Tasmanian endemic shrub Richea dracophyllum (Ericacea) during the night in winter prompted us to carry out a more extensive study of pollination of R ...
