Lateral view of petiole, adult worker. Petiole narrowly attached to gaster; conspicuous posterior face.
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.
Close-up view of frontal carina, adult worker. Frontal lobes narrow. Photo by Estella Ortega, Antweb.org, modified.
Anterior view of antennal scape, adult worker. The antennal scapes, when arranged along the anteroposterior axis of the head, do not reach the posterior head margin. Used in Antkey to separate Hypoponera punctatissima, Hypoponera ragusai and Hypoponera zwaluwenburgi from Hypoponera opaciceps and Pachycondyla species.
Lateral view of head, adult worker. There are no pigmented ommatidia visible on the head. If a facet is visible, it not distinctly pigmented. Used in Antkey to separate Amblyopone zwaluwenburgi, Prionopelta antillana, Cerapachys biroi and Hypoponera zwaluwenburgi from all other species.
Lateral view of waist, adult worker. The petiole is subtriangular, relatively short and broad with distinctly convex anterior and posterior faces. The subpetiolar process is reduced to a small convexity that weakly breaks the outline of the ventral margin. Used in Antkey to separate Hypoponera zwaluwenburgi from Hypoponera opaciceps, Hypoponera punctatissima and Hypoponera ragusai.
Anterior view of head, adult worker. Eyes situated distinctly above midline of face. Nesting in sand.
Anterior view of mouthparts, adult worker. Anterior clypeal margin with one median and two lateral rounded projections.
Anterior view of clypeus, adult worker. The anterior clypeal margin with three convexities (one median and two lateral). Used to distinguish Iridomyrmex from all other dolichoderine genera in Antkey.

Close-up view of mandibles, adult worker. The mandible has eight total teeth and dents, including 2 basal teeth. Used in Antkey to separate Lasius alienus from Lasius neglectus but it is not always reliable.
Close-up view of mandibles, adult worker. The mandible has seven total teeth and dents, including 2 basal teeth. Used in Antkey to separate Lasius neglectus from Lasius alienus, but it is not always reliable.
