Number of countries occupied by this species based on AntWiki Regional Taxon Lists. In general, fewer countries occupied indicates a narrower range, while more countries indicates a more widespread species.
Relative abundance based on number of AntMaps records per species (this species within the purple bar). Fewer records (to the left) indicates a less abundant/encountered species while more records (to the right) indicates more abundant/encountered species.

Taylor and Alpert (2016) - (After Eguchi, 1998): TL 4.9–8.3; HL: 1.11–1.91; HW: 0.76–1.33; CI: 68, 70. CpL: 0.43–0.68; CpI: 39, 36; MSL: 1.30–2.44; PML: 0.63–1.26; PMW: 0.55–1.07; PMI: 48, 56; PDW: 0.48–0.88; PetL: 0.33–0.63; PetW: 0.35–0.68; PetH: 0.50–0.88; PpetL: 0.33–0.64; PpetW: 0.42–0.83; GW: 0.80–1.41. The cited indices were calculated from Eguchi’s smallest and largest measurements for HL and HW (CI), HL and CpL (CpI) and MSL and PML (PMI). Cephalic proportions stated in the original description are equivalent to a CI range of 67–71, and the holotype has CI 71. Additional measurements are given with the original description. The smallest and largest of four paratype workers studied here have: HL (midline) 1.21, 1.68; HL (maximum) 1.26, 1.70; HW 0.87, 1.19; CI (based on midline HL) 72 71; PMW 0.57, 0.92. Note that Eguchi measured maximum HL so as to include the occipital lobes. Our measurements are taken from the midline of the occipital border.
General features as in original description (Eguchi, 1998), the key to Asian species and figures. Eyes relatively moderately large, multifaceted, maximum diameter around 2/3 the maximum width of an apical antennomere. Subpetiolar lamella in profile 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
