Metapone madagascarica

Known from a variety of forest types (spiny forest/thicket, gallery forest, spiny forest, secondary rainforest, tropical dry forest, tropical forest) in dead wood, e.g., rotten logs and a stump.

Identification
Taylor and Alpert (2016) - General and diagnostic features as illustrated and in the key to African and Madagascan species above (note paired anteromedian clypeal denticles, sub-parallel lateral clypeal margins, transverse petiolar node, and unextended postpetiolar sternite). Eyes minute, diameter of each about half the width of the second funicular antennomere; with 8–10 extremely minute, somewhat obscure facets. Mesosoma In dorsal view slightly constricted at promesonotal/propodeal junction, with accompanying short vestigial traces of the metanotal suture on each side. Subpetiolar process: more-or-less basic in structure—relatively deep, the posterior face a narrow isosceles triangle, subpetiolar angle obtuse in side view, without spinose extension. Subpetiolar extension lamellate, scalene-triangular, with a short posteroventral edge, the apex posteroventral, the base almost as long as the subpetiolar edge.
