Molecular phylogenetics of ponerine ants (Hymenoptera: Formicidae: Ponerinae).

Recent molecular phylogenetic studies of ants (Hymenoptera: Formicidae) have revolutionized our understanding of how these ecologically dominant organisms diversified, but detailed phylogenies are lacking for most major ant subfamilies. I report the results of the first detailed phylogenetic study of the ant subfamily Ponerinae, a diverse cosmopolitan lineage whose properties make it an attract...

SPRINGTAILS (COLLEMBOLA) FROM NESTS OF PONERINAE (HyMENOPTERA: FORMICIDAE) ANTS IN BRAZILIAN CACAO PLANTATIONS

Cytogenetic analysis of Pseudoponera stigma and Pseudoponera gilberti (Hymenoptera: Formicidae: Ponerinae): a taxonomic approach

Pseudoponera stigma (F.) and Pseudoponera gilberti (Kempf) (Hymenoptera: Formicidae) are closely related Neotropical ants, often misidentified due to their morphological similarities. These species also share behavioral and ecological characters. In this study, we examined cytogenetic approaches as a tool to aid identification of P. stigma and P. gilberti. Both numerical and morphological karyo...

On the evolution of the species complex Pachycondyla chinensis (Hymenoptera: Formicidae: Ponerinae), including the origin of its invasive form and description of a new species

Ants are one of the most successful and widespread organisms in the world. Although ants of the genus Pachycondyla (Hymenoptera: Formicidae: Ponerinae) are predominantly tropical in distribution, Pachycondyla chinensis (Emery) is especially abundant in temperate zones in Asia. Recently, P. chinensis has also become an abundant invasive ant species in the United States. However, it was well-know...
