Abstract. The fire ants of the Solenopsis geminata species-group of Trager (1991) are revised based on the morphology of worker larvae and of adult forms of workers, males, and gynes (winged or dealated members of the queen caste). The amount of intraspecific variation occurring in the adult males and gynes was equivalent to that of workers, making the taxonomic information gained from these castes no better than information from the workers. A new species, S. metallica, is described from… Expand
Myrmecophily and Myrmecophagy of Attacobius lavape (Araneae: Corinnidae) on Solenopsis saevissima (Hymenoptera: Myrmicinae)
TLDR
An extension study on a small spider living inside a fire ant colony of Solenopsis saevissima species in the municipality of Morrinhos, south region of the Goias State, Brazil, to determine its local and regional occurrence and investigated if the spider uses the host ant as a feeding source. Expand
A Small Parasitoid of Fire Ants, Pseudacteon obtusitus (Diptera: Phoridae): Native Range Ecology and Laboratory Rearing
TLDR
Pseudacteon obtusitus has 2 seasons of peak abundance, and exhibits low tolerance for cold temperatures or extended cold periods, and holds interest for inclusion among the multi-species assemblage of parasitoid flies considered for biological control of S. invicta in its invasive range in North America. Expand
A Species delimitation approach to uncover cryptic species in the South American fire ant decapitating flies (Diptera: Phoridae: Pseudacteon)
TLDR
All phylogenetic analyses reveal that South American fire ant decapitating flies are grouped into two main clades, with Pseudacteon convexicauda sister and well differentiated relative to these clades. Expand
Systematics and diversity of Neotropical ants / Sistemática y diversidad de las hormigas neotropicales
With a long history of more than 100 million years and about 14,000 described living species, ants are one of the most important and well-known groups of insects in the world. Ants are key elementsExpand
Bacterial transfer from Pristionchus entomophagus nematodes to the invasive ant Myrmica rubra and the potential for colony mortality in coastal Maine
Summary The necromenic nematode Pristionchus entomophagus has been frequently found in nests of the invasive European ant Myrmica rubra in coastal Maine, United States, and may contribute to antExpand
Molecular phylogenetic analysis and morphological reassessments of thief ants identify a new potential case of biological invasions
TLDR
This work inferred a phylogeny of the two species using DNA sequence data from four nuclear genes and one mitochondrial gene sampled from populations in Florida, Guatemala, Hawaii, and Saudi Arabia and indicated that S. abdita is a novel global tramp species which has a far wider distribution than previously thought and has established itself in many new habitats and different geographic realms. Expand
Speciation and hybridization in invasive fire ants
TLDR
Evidence for complete genetic isolation maintained between two invasive species in their natïve range is provided, based, for the first time, on large scale genomic data analysis. Expand
Chemical blueprints to identifying fire ants: overview on venom alkaloids
TLDR
A set of chemical tools to facilitate species diagnosis from field-collected fire ant samples are introduced, herein focusing on minor workers, to help researchers working on fire ants in future studies. Expand
Chemical blueprints to identifying fire ants: overview on venom alkaloids
TLDR
A set of chemical tools to facilitate species diagnosis from field-collected fire ant samples are introduced, herein focusing on minor workers, to help researchers working on fire ants in future studies. Expand
Joint Evolution of Asexuality and Queen Number in an Ant
TLDR
The intersection of social polymorphism, facultative asexuality, and genetic caste determination marks this population of S. geminata as an embodiment of the diversity of ant reproductive systems and suggests previously unknown connections between these phenomena. Expand

Cladistic analysis of the fire ants of the Solenopsis saevissima species‐group (Hymenoptera: Formicidae)
TLDR
This phylogenetic hypothesis implies trends in fire ant evolution towards both polygyny (multiple egg‐laying queens per colony) and large major worker size, which is supported by a modified version of Emery's Rule. Expand
Solenopsis Enigmatica, a New Species of Inquiline Ant from the Island of Dominica, West Indies (Hymenoptera: Formicidae)

Abundance of the Parasitic Ant Solenopsis daguerrei (Hymenoptera: Formicidae) in South America, a Potential Candidate for the Biological Control of the Red Imported Fire Ant in the United States
TLDR
The low presence of the workerless parasitic ant Solenopsis daguerrei in fire ant populations should not discourage the potential use of this parasite as a biological control agent of imported fire ants in the United States. Expand
Distribution of the fire ant (Hymenoptera: Formicidae) hybrid in Georgia.
TLDR
The red imported fire ant, Solenopsis invicta Buren, and the black importedFire ant, S. richteri Forel, are reproductively isolated in their native South America even where their ranges overlap, and hybridization occurred upon arrival of these two species in North America. Expand
Symposium: New Technologies for the Taxonomic Identification of Arthropods: Use of Chemical Characters in Defining Populations of Fire Ants, Solenopsis Saevissima Complex, (Hymenoptera: Formicidae)
TLDR
The use of three species-specific chemical characters (venom alkaloids, cuticular hydrocarbons, and trail pheromones) to define S. invicta, S. richteri, and hybrid populations in the United States have important consequences regarding the species status of the two imported fire ants and the taxonomy of fire ant populations in South America.
