Description
Worker diagnosis. General features as in original description (Eguchi, 1998), the key to Asian species and illustrated here. Eyes relatively moderately large, multifaceted, maximum diameter around 2/3 the maximum width of an apical antennomere. Subpetiolar lamella in profile (Fig. 55) an anteriorly positioned, erect, translucent, posteroventrally bluntly-pointed hook-like structure, behind which the ventral subpetiolar edge curves quite strongly to meet the subpetiolar angle which encloses approximately 90° in lateral view. Posterior subpetiolar face approximately equilaterally triangular in oblique view, its outer margins with a fine raised, translucent, laminate carina which is higher towards the apex of the posterior face, and forms a distinctive translucent margin to the posterior subpetiolar profile in lateral view, visually doubling the outline. Subpostpetiolar process barely inflated anteroventrally, forming a slightly acute angle in profile; the anterior face small, sub-semicircular in oblique view
