Ectatomma Smith

Type Species: Ectatomma tuberculatum (Olivier)

Diagnosis (Females): Occipital lobe absent. Antennal club absent. Palp formula 2,2. Pronotum usually with two or three tubercles. Mesonotum prominent and clearly differentiated from propodeum, separated by a deep transverse suture. Promesonotal suture well marked, interrupting or not the dorsal mesosomal sculpture. Propodeal spiracle elliptical or slit-shaped and separated from the declivous face of propodeum by a distance longer than its diameter. Apex of protibia with a stout seta close to the strigil base; dorsum of posterior coxa without projections.

Species: brunneum , confine , edentatum , gibbum , goninion , † gracile , lugens , muticum , opaciventre , parasiticum , permagnum , planidens , ruidum , suzanae , tuberculatum , and vizottoi .

Distribution: Exclusively found in the New World, from USA (Texas) to Argentina (Buenos Aires).

Notes: Ectatomma are among the most conspicuous elements of the ant fauna in Neotropical ecosystems. Currently, the most comprehensive work including an identification key for the species in the genus is the revision by Kugler and Brown (1982). However, this work does not include the species Ectatomma parasiticum Feitosa and Fresneau , in Feitosa et al. (2008), E. suzannae Almeida (1986) and E. vizottoi Almeida (1987) .
