Description
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.
