( 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.

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.

Dimensions: The original description gives the following measurements (Holoytpe; paratypes): HL 1.20 mm, 1.20–1.44 mm; HW 0.90 mm, 0.90–1.06 mm; ML 1.60 mm, 1.58–1.90 mm; PML 0.90 mm, 0.90–1.24 mm; PMW. 64 mm, 0.60–0.76 mm; PNL 0.34 mm, 0.32–0.46 mm; PetW 0.44 mm, 0.44–0.68 mm; PPW 0.46 mm, 0.44–0.62 mm.
