Lateral view of thorax / mesosoma, adult. Metanotum does not form a prominent convexity bordered by distinct suture lines.
Lateral view of metanotum, adult worker. Metanotum does not form a prominent convexity bordered by distinct suture lines. Used in Antkey to separate Gnamptogenys from Ectatomminae.
Lateral view of petiole, adult. Petiolar node tall and narrow and the subpetiolar process narrow with a blunt posterior angle and lacking a distinct anterior angle.
Lateral view of petiole, adult worker. Petiolar node tall and narrow and the subpetiolar process narrow with a blunt posterior angle and lacking a distinct anterior angle. Separates Gnamptogenys porcata from G. triangularis.
Lateral view of propodeum, adult. Propodeum is entirely unarmed, completely lacking even small angles or teeth. Used in Antkey to separate Gnamptogenys porcata from G. triangularis.

Anterior view of antennal scape, adult worker. Antennal scape does not exceed posterior head margin.
Anterior view of antennal scape, adult worker. Antennal scapes reach or exceed posterior head margin.
Anterior view of antennal scape, adult worker. The antennal scapes, when arranged along the anteroposterior axis of the head, extend beyond the posterior head margin. Used in Antkey to separate Hypoponera opaciceps and Pachycondyla species from Hypoponera punctatissima, Hypoponera ragusai and Hypoponera zwaluwenburgi.
Lateral view of petiole, adult worker. The petiole is subrectangular, relatively tall and narrow and with a nearly flat anterior face. The subpetiolar process is well developed and strongly convex. Used in Antkey to separate Hypoponera opaciceps, Hypoponera punctatissima and Hypoponera ragusai from Hypoponera zwaluwenburgi.
