petiole
waist with spongiform
waist with spongiform
Spongiform is attached to at least some portion of waist. Used in Antkey to separate Strumigenys and Strumigenys from Cyphomyrmex and Eurhopalothrix.
petiolar node tall and narrow
petiolar node tall and narrow
The petiolar node tall and narrow and the subpetiolar process narrow with a blunt posterior angle and lacking a distinct anterior angle. Used in Antkey to separate Gnamptogenys porcata from Gnamptogenys triangularis.
petiole with posterior face
petiole with posterior face
The petiole is attached to the gaster by a narrow attenuation and always has a conspicuous posterior face. Used in Antkey to separate all other subfamilies from Amblyoponinae.
petiolar node height
petiolar node height
The vertical height of the petiole measured in profile from the lowest point of the subpetiolar process to a line that intersects the highest point of the dorsal outline (Bolton & Fisher 2011).
petiolar node length
petiolar node length
In profile, the maximum length of the petiole node, measured in a straight horizontal
line from immediately above the dorsal base of the anterior petiolar tubercle to the posterior margin (Bolton & Fisher 2011).
petiolar node width
petiolar node width
The maximum width of the petiole node in dorsal view
petiole apendunculate
petiole apendunculate
The petiole is apedunculate and approximately as tall and it is long in profile view. The posterior face is weakly but distinctly concave. Used in Antkey to separate Platythyrea parallela from other ponerine species.
petiole subtriangular
petiole subtriangular
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.
petiole subrectangular
petiole subrectangular
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.
petiole taller than long
petiole taller than long
The petiole is distinctly taller than long in profile, and the posterior face is flat to convex, but never concave. Used in Antkey to separate other ponerine species from Platythyrea parallela.
