Description

Worker

(holotype, smallest paratype, largest paratype (ranked by HW): TL: ca. 8.95, 6.4, 9.3; HL: 2.12, 1.47, 2.13; HW: 1.52, 1.05, 1.57; CI: 72, 71, 74; PMW: 1.11, 0.72, 1.12; MSL: 2.31, 1.55, 2.40; PetL: 0.69, 0.46, 0.70; PetW: 0.60, 0.47, 0.62; PetH: 1.05, 0.75, 1.10; PpetL: 0.63, 0.46, 0.66; PpetW: 0.80, 0.58, 0.82; PpetH: 0.85, 0.60, 0.90; GW 1.58, 1.15, 1.66.

General and diagnostic features as in the key to Asian species 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.
