Bolton (2000) - A member of the Strumigenys scotti-group. Mandibles stout and relatively short, the outer margins weakly convex and each blade suddenly narrowed at base. Scape short (compare with SI range for remainder of group), weakly dorsoventrally flattened and with a convex leading edge that is equipped with a row of curved, narrowly spoon-shaped hairs. Preocular notch absent. Upper scrobe margin fringed with a row of large spoon-shaped hairs that are much larger than those on the leading edge of the scape.

Holotype. TL 2.0, HL 0.57, HW 0.46, CI 81, ML 0.23, MI 40, SL 0.27, SI 59, PW 0.30, AL 0.52.
Mandibles stout, the outer margins shallowly convex in full-face view and sharply incurved basally where the blades suddenly narrow to their insertions. Apical fork of each mandible with 2 spiniform teeth, without intercalary teeth or denticles. Each mandibular blade with 2 stout preapical teeth, the proximal about one-third longer than the distal and their bases separated by a distance which is slightly less than the length of the distal pre apical tooth. Upper scrobe margins very feebly sinuate in full-face view, bordered by a narrow rim or flange and meeting the sides of the occipital lobes (at the scrobal apices) in an obtuse but distinct angle, the upper scrobe margins not merging smoothly into the sides of the occipital lobes. Eyes of moderate size, with 5 ommatidia across the greatest diameter and with 15 or more ommatidia in all. Maximum diameter of eye greater than the maximum width of the scape. Preocular notch absent, ventral surface of head without a transverse pre ocular groove or impression. Antennal scapes narrow and shallowly curved basally, expanded in the meqian third and with the leading edges equipped with a row of apically curved spoon-shaped hairs which are distinctly smaller than those fringing the upper scrobe margins. Ground-pilosity of cephalic dorsum of inconspicuous small flattened hairs, the upper scrobe margins with a row of large spoon-shaped hairs. Dorsum of head with 6 standing hairs, arranged in a transverse row of 4 close to the occipital margin and a more anteriorly situated pair. Dorsum of head densely reticulate-punctate. Pronotal humeri each with a fine flagellate hair. Mesonotum with a single pair of stout standing hairs which are thickened apically. Ground-pilosity of dorsal alitrunk of inconspicuous small hairs like those on the head. Posterior portion of mesonotum very slightly depressed behind the level of the pair of hairs, the metanotal groove forming a weak line across the dorsum. Propodeal teeth short and triangular, subtended by relatively broad infradental lamellae which at their broadest extend posteriorly almost as far as the apices of the teeth. Sides of pronotum feebly punctate-striolate, the pleurae and sides of propodeum mostly smooth but with some peripheral punctate sculpture. Pronotum finely and quite densely longitudinally rugulose, the remainder of the dorsal alitrunk reticulate-punctate. Dorsum of petiole node finely punctate, the postpetiole smooth. Ventral spongiform strip of petiolar peduncle narrow, broadening beneath the node. Lateral spongiform lobe of postpetiole equal to or slightly exceeding the exposed area of the disc in profile. In dorsal view the lateral spongiform material is visible, projecting beyond the outline of the sides of the postpetiole. Basigastral costulae sparse, 5-6 arising on each side of a narrow clear central area. Petiole, postpetiole and gaster dorsally with stout standing hairs which are thickened apically. Colour blackish brown.
Paratypes. TL 2.0, HL 0.53-0.54, HW 0.43-0.44, CI 81, ML 0.23, Ml 42-43, SL 0.26, SI 59-60, PW 0.27, AL 0.50-0.52 (2 measured).
As holotype but one lighter in colour than the holotype and probably teneral.
