We noted a strong congruence between the two studies permitting us to delimit 2 supercolonies extending over large distances (up to 54 km), a phenomenon known as unicoloniality. Solenopsis geminata workers, taken as an out-group for cluster analyses, have a very different cuticular hydrocarbon profile. Because S. saevissima has been reported outside its native range, our conclusion is that this species has the potential to become invasive because unicoloniality (i.e., the main attribute for ants to become invasive) was shown at least for the Guianese population. © 2015 Institute of Zoology, Chinese Academy of Sciences UR - https://www.scopus.com/inward/record.uri?eid=2-s2.0-84987971090&partnerID=40&md5=2717a172b1bcb25a0383dcc0435e9a79 UR - http://dx.doi.org/10.1111/1744-7917.12232 N1 - Export Date: 3 October 2016 ID - Lenoir_etal2016 ER -
