Mitochondrial DNA Part A, 2018
We assembled mitogenomes from 21 ant workers assigned to four morphospecies (E. ruidum spp. 1-4) and putative hybrids of the Ectatomma ruidum complex (E. ruidum spp. 2x3), and to E. tuberculatum using NGS data. Mitogenomes from specimens of E. ruidum spp. 3, 4 and 2 × 3 had a high proportion of polymorphic sites.

In the ectatommine ant Ectatomma tuberculatum, the visual appearance of queens changes after mating and ovarian development in that their cuticle turns from shiny to matte. In this study, we have shown that this change seems to be caused by 15-fold accumulation of hydrocarbons, in particular heptacosane that covers the multiple grooves present on the ...

Journal of Systematic Palaeontology, 2012
Ants are a very successful group among insects, but the course of evolution of their biodiversity is still unclear. This study sheds light on ant diversification during the Eocene. Analysis of the ant taphocoenosis of the fossil site Grube Messel, Germany (47 Ma) yielded three poneromorph subfamilies and 22 new species in six genera, four of which are ...

Insectes Sociaux, 2005
The ability of worker ants to adapt their behaviour depending on the social environment of the colony is imperative for colony growth and survival. In this study we use the greenhead ant Rhytidoponera metallica to test for a relationship between colony size and foraging behaviour.

Journal of Insect BiodiversityHunter ants are among top invertebrate predators in tropical forests and play a key role in regulating invertebrate populations. This study documents new records of Ectatomminae and Ponerinae ants in the Colombian Amazon Basin. We provide the first country record of the genus and species Corrieopone nouragues, as well as new country records for ten ...

Organisms Diversity & Evolution, 2015
Due to its high biodiversity and its complex climatic and geological history, the Neotropical region has caught the attention of evolutionary and conservation biologists. The Neotropics have an understudied and probably extensive cryptic diversity, stemming from old lineages that have persisted through time with highly similar morphology or from new ...

Gnamptogenys includes 138 described species that are widely distributed, with high diversity, in the Neotropics. Some Neotropical species have taxonomic issues, as is the case with Gnamptogenys striatula, for which morphological variations have been observed between different populations.
