Nomenclature

 *  macerina. Strumigenys macerina Bolton, 2000: 761 (w.) BORNEO.

Worker
Holotype. TL 3.1, HL 0.84, HW 0.55, CI 65, ML 0.32, MI 38, SL 0.48, SI 87, PW 0.34, AL 0.90. Mandible relatively short, with a preapical tooth. Dorsolateral margin of head in full-face view with 10 or more freely laterally projecting long filiform hairs, most of them arising from prominent tubercles. Shorter laterally projecting hairs also present on ventrolateral margin of head. Cephalic dorsum with numerous erect fine hairs that arise all over the surface from in front of level of eye to occipital margin. Ventral surface of head with shorter, sparser erect hairs. Dorsum of head finely and densely punctate-rugulose. Apical funicular segment moderately constricted basally. Promesonotal dorsum finely densely punctate-rugulose. Pleurae and side of propodeum everywhere densely punctate to reticulate-punctate. Pronotal humeral hair very long. Dorsal alitrunk with abundant erect simple hairs, filiform to sub flagellate, the number of pairs not easily counted; those on dorsolateral margin of mesonotum arise from discrete tubercles. Waist segments and first gastral tergite with abundant similar hairs. Dorsal, ventral and lateral surfaces of hind femur with rows of suberect/erect hairs; dorsal (outer) surfaces of hind tibia and basitarsus each with long erect freely projecting hairs. Propodeal teeth long, much longer than basal width in profile and weakly upcurved. Petiole in profile claviform, in dorsal view much longer than broad.

The single Sumatran specimen measures HL 0.86, HW 0.58, CI 67, ML 0.32, MI 37, SL 0.48, SI 83, PW 0.33, AL 0.89.
