Metapone vincimus Alpert, 2007 ( Figs 8–11 ) Metapone vincimus, Alpert, 2007 : 11 , Figs 1, 2 , 7 , 8 —Worker, Intermorph, Gyne; Type locality: 30km N of Antalaha, 3km W to a hill near Amboangy (14˚39’53.3”N, 50˚1’26.5”E), Madagascar . FIGURES 8–11. Metapone vincimus , paratype worker, HW 0.75, PMW 0.56, MSL 1.20. Worker diagnosis. General and diagnostic features as illustrated and keyed above (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 M. madagascarica above. Subpetiolar process ( Fig 9 ) 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.
