( Figs 62–65 View FIGURES 62 – 65 )

Type locality. INDONESIA: java: near Cibodas Botanical Garden [6°44′S, 107°E].

Type deposition. MZBI: holotype worker, 6 paratype workers, paratype dealate gyne, 2 paratype males. ANIC: 2 paratype workers, 2 paratype males. Single paratype workers in BMNH, CASC, IZUK, MCZC, MHNG.

Distribution, material examined. Known only from the type nest series comprising the holotype worker, 18 paratype workers, a paratype dealate queen and 4 paratype males, collected by K. Yamauchi (5/Jan/2000, “nesting in a fallen tree in primary forest”).

Worker diagnosis. General and diagnostic features as in the key to Asian species above and the accompanying Figures. Clypeus rostrate, transverse anterior border straight, without accessory denticles. Eyes relatively large, minutely multifaceted, maximum diameters subequal to the maximum width of an apical antennomere. Subpetiolar lamella a translucent, anteriorly-positioned hook-like structure, much as described above for M. quadridentata . Profile of subpetiolar edge behind the lamella curving posteroventrally on a longer radius than in M. quadridentata to meet the subpetiolar angle, which is drawn to an acute point in side view. Posterior subpetiolar surface acutely triangular in oblique view, its face minutely concave, with the outer edges distinctly margined but not carinate, sloping so strongly forwards that its ventral profile almost aligns with the subpetiolar edge. Subpostpetiolar process slightly extended, acutely triangular in lateral view.
