“…Samples were taken from nine ant populations: three S. invicta and two S. richteri populations in the native range in Northeastern Argentina; two S. invicta and two S. richteri populations in the introduced range in Southeastern USA. The specimens were identified by morphological characteristics by James Pitts as described before [48]. For each population, 23–51 diploid females were sampled, each from a different colony, totaling 337 individuals.…”

Background A major focus of evolutionary biology is the formation of reproductive barriers leading to divergence and ultimately, speciation. Often, it is not clear whether the separation of populations is complete or if there still is ongoing gene flow in the form of rare cases of admixture, known as isolation with migration. Here, we studied the speciation of two fire ant species, Solenopsis invicta and Solenopsis richteri , both native to South America, both inadvertently introduced to North America in the early twentieth century. While the two species are known to admix in the introduced range, in the native range no hybrids were found. Results We conducted a population genomic survey of native and introduced populations of the two species using reduced representation genomic sequencing of 337 samples. Using maximum likelihood analysis over native range samples, we found no evidence of any gene flow between the species since they diverged. We estimated their time of divergence to 190,000 (100,000–350,000) generations ago. Modelling the demographic history of native and introduced S. invicta populations, we evaluated their divergence times and historic and contemporary population sizes, including the original founder population in North America, which was estimated at 26 (10–93) unrelated singly-mated queens. Conclusions We provide evidence for complete genetic isolation maintained between two invasive species in their natïve range, based, for the first time, on large scale genomic data analysis. The results lay the foundations for further studies into different stages in the formation of genetic barriers in dynamic, invasive populations.

“…In the municipality of Morrinhos, south region of the Goiás State, we have found adults (males and females) and young A. lavape inside the Solenopsis saevissima (F. Smith, 1855) colonies. Solenopsis saevissima has a wide distribution in South America and, as well as other 19 species belonging to the fire ants, it is known by its painful sting and mass attack (Pitts et al, 2018). Similar to the Solenopsis invicta Buren, 1972 species in the south region of the United States, when introduced in other regions, the fire ants can cause serious structural, ecological and public health problems (Tschinkel, 2006).…”

“…We quantified the collecting areas (ha), the number of colonies found and the number of A. lavape individuals present in the colonies to estimate the local and regional occurrence of ants and spiders. We followed Pitts et al (2018) review for the identification of fire ants and Bonaldo et al (2018) for the identification of the inquiline spider.…”

Myrmecophily and Myrmecophagy of Attacobius lavape (Araneae: Corinnidae) on Solenopsis saevissima (Hymenoptera: Myrmicinae)

Attacobius lavape, a small spider from the Corinnidae family, has been recently described living inside a fire ant colony of Solenopsis saevissima species in the municipality of Morrinhos, south region of the Goiás State, Brazil. Yet several aspects of this spider relationship with the host ant remain unknown. In this way, we performed an extension study to determine its local (Morrinhos) and regional (latitudinal transect) occurrence. We also investigated if the spider uses the host ant as a feeding source. For this, we established arenas with a known number of young and adult ant individuals plus one spider and observed the feeding rate for some determined time. Regarding local distribution, differently from most socially parasitic myrmecophiles, A. lavape showed high local infestation, being found in 47% of the colonies in the sites where the spider occurred, and high transmission, being found in 42% of the 12 collection sites. Regionally, among the 11 study sites, this species only occurred in the municipality of Morrinhos, but its distribution still needs to be verified in the north region. Attacobius lavape consumed eggs, larvae and pupae, confirming that the myrmecophily was explained by myrmecophagy. The spiders consumed eggs (not estimated), 4.45 ± 2.14 larvae and/or 3 ± 0.87 pupae per day. Considering that the mean abundance was approximately seven spiders per colony (extent 1-23), we foresee an impact of 35 larvae and/or 21 pupae consumed per day in each hosting colony. The possibility of consuming sexual eggs, larvae and pupae classifies A. lavape as a potential agent of biological control of S. saevissima.
