SUBFAMILY AMBLYOPONINAE - Genus Prionopelta
|Contents - Amblyoponinae - Subfamily Amblyoponinae|
In Tribe AMBLYOPONINI.
Diagnostic Features - Petiole broadly attached to the first gastral segment, the two separated dorsally and laterally only by a constriction; so that the petiole is without a free posterior face. Mandibles relatively short triangular and closing against the clypeus, apical tooth followed by two more teeth. Antenna 8- to 12-segmented with a 3- or 4-segmented club. Alitrunk not marginate nor constricted.
A cryptobiotic genus, post-dating Bolton (1973a) but included in the key in Hölldobler & Wilson (1990).
