A revision of the giant Amazonian ants of the genus Dinoponera (Hymenoptera, Formicidae)

Abstract: Dinoponera Roger 1861 has been revised several times. However, species limits remain questionable due to limited collection and undescribed males. We re-evaluate the species boundaries based on workers and known males. We describe the new species Dinoponera hispida from Tucuruí, Pará, Brazil and Dinoponera snellingi from Campo Grande, Mato Grosso do Sul, Brazil and describe the male of Dinoponera longipes Emery 1901. Additionally, we report numerous range extensions with updated distribution maps and provide k… Show more

“…However, this ant was also seen in sunny sites. In such climate condition, the nests of D. gigantea were always observed at the bottom of the trunk of trees and shrubs, which is possibly a strategy that reduces the effects of high temperatures as argued by Lenhart et al (2013) and Vasconcellos et al (2004). Despite the preference of D. gigantea for mild temperatures and humidity sites, the excess of humidity is a limitation for the occurrence of D. gigantea, because these ants were not found in sites where there is high soil water content (close to saturation).…”

“…A reprodução é por meio de operárias férteis (gamergates) e a competição para o posto de fêmea alfa do ninho é intensa. Uma revisão taxonômica do gênero com um resumo sobre sua biologia foi recentemente publicada por Lenhart et al (2013).…”

“…Das oito espécies descritas do gênero Dinoponera (LENHART et al, 2013), cinco têm os números cromossômicos conhecidos (SANTOS et al, 2012, Tabela 10.I). Este é o gênero mais próxi-mo de Pachycondyla, assim ambos compartilham características ecológicas, morfológicas e moleculares, além de citogenéticas .…”

“…In contrast, Dinoponera is a genus of ponerine ants that, like several other ponerine ant genera, has lost a morphologically distinct queen caste. It has small perennial colonies [average colony size of Dinoponera quadriceps is 80 workers (9)] and young workers can reproduce and become the dominant egg layer (queen). In general, ponerine queens show very little morphological differentiation from their workers, with the exception of wings that they shed after the mating flight.…”
