Metapone vincimus

Identification
Petiolar node from above approximately as wide as long; postpetiolar sternum in side view bluntly rounded.

Taylor and Alpert (2016) - General and diagnostic features as illustrated and keyed (note paired anteromedian clypeal denticles, sub-parallel lateral clypeal margins, petiolar node in dorsal view approximately as wide as long, and unextended postpetiolar sternite). Eyes very small, much as described for Metapone madagascarica. Subpetiolar process more-or-less basic in structure: posterior face approximately equilaterally triangular, subpetiolar angle obtuse, its apex minutely rounded in side view. Subpetiolar extension lamellate, a shallow isosceles triangle, the posterolateral edge slightly concave in side view, the base almost as long as the subpetiolar edge.
