Chromosomal diversity in Lund, 1831 (Formicidae: Myrmicinae) from the Amazon rainforest.

Lund, 1831 is a speciose ant genus globally distributed and easily recognizable. Although biogeographical theories explain some variation among Neotropical , several taxonomical issues remain unresolved. While cytogenetic approaches can help to delimit species, cytogenetic data are only available for 18 taxa.

Karyotype conservation and genomic organization of repetitive sequences in the leaf-cutting ant (Linnaeus, 1758) (Formicidae: Myrmicinae).

Leaf-cutting ants are among the New World's most conspicuous and studied ant species due to their notable ecological and economic roles. Cytogenetic studies carried out in show remarkable karyotype conservation among the species. We performed classical cytogenetics and physical mapping of repetitive sequences in the leaf-cutting ant (Linnaeus, 1758), the type species of the genus.

Cytogenetic data for sixteen ant species from North-eastern Amazonia with phylogenetic insights into three subfamilies.

Ants play essential roles in most terrestrial ecosystems and may be considered pests for agriculture and agroforestry. Recent morphological and molecular data have challenged conventional ant phylogeny and the interpretation of karyotypic variations. Existing Neotropical ant cytogenetic data focus on Atlantic rainforest species, and provide evolutionary and taxonomic insight.
