Gnamptogenys Roger

= Commateta Santschi

= Emeryella Forel

= Tammoteca Santschi

Type Species: Gnamptogenys sulcata (Smith)

Diagnosis (Females): Head subquadrate to elongate. Mandible subtriangular to subfalcate. Occipital lobe absent. Antennal club absent. Palp formula 2,2 to 3,2. Pronotum unarmed and without tubercles. Promesonotal suture feebly impressed to absent, never interrupting dorsal mesosomal sculpture, sometimes with a small pit frequently situated medially on a weakly impressed promesonotal suture. Mesonotum not prominent, forming a continuous line with the propodeum, separated by a transverse suture. Propodeal spiracle oval or rounded, separated from the declivous face of propodeum by a distance longer or shorter than its diameter. Apex of protibia without a stout seta close to the strigil base; dorsum of posterior coxae frequently with a lobe or spine.

Species: acuminata, alfaroi, andersoni, annulata, biquetra, boliviensis, bruchi, † casca, concinna, continua, curvoclypeata, ericae, † europaea, falcaria, fernandezi, flava, haenschi, hartmani, horni, interrupta, kempfi, † levinates, lucaris, mordax, nana, † pristina, regularis, rimulosa, † rohdendorfi, rugimala, rumba, schmitti, siapensis, stellae, sulcata, tortuolosa, transversa, and volcano.

Distribution: Exclusively found in the New World, from USA (Texas) to Argentina (Buenos Aires), with one species occurring in Cuba.

Notes: In the new concept proposed here, Gnamptogenys is now restricted to the species from the previous sulcata, concinna, and mordax groups (sensu Lattke 1995), considering that G. sulcata is the type-species of the genus. All except one of the species of Gnamptogenys can be identified using the work of Camacho et. al. (2020). Gnamptogenys rugimala , a newly described species, can be identified using the paper by Marcineiro and Lattke (2020).
