Nomenclature

 *  leptodeira. Strumigenys leptodeira Bolton, 2000: 858 (w.) WEST MALAYSIA.

Worker
Holotype. TL 3.1, HL 0.88, HW 0.70, CI 80, ML 0.38, MI 43, SL 0.43, SI 61, PW 0.41, AL 0.82. Length of preapical tooth distinctly less than maximum width of mandible. Dorsolateral margin of occipital lobe with a shorter laterally projecting flagellate hair posterior to the apicoscrobal hair. Cephalic dorsum with simple soft dense ground pilosity; anteriorly it is quite closely applied to the surface but posteriorly tends to be more elevated. Head appears to lack standing longer hairs of any form. Dorsal alitrunk with similar ground-pilosity and again longer standing hairs seem absent except for a pair on the pronotum, but most material is either abraded or coated with dirt; possibly more could be present in clean material. Gastral pilosity very reduced, see group diagnosis. Femora do not have erect hairs on their dorsal surfaces. Dorsal (outer) surface of hind tibia with one (may be two) erect long fine hairs that are however shorter than those on the basitarsus and are apparently easily abraded away. Dorsum of head extremely finely punctate-rugulose. Pronotal dorsum very weakly rugulose, side of pronotum very weakly superficially punctulate. Katepisternum, metapleuron and side of propodeum smooth. Petiole node in profile with a short steep anterior face and a longer, more shallowly sloping dorsum. In dorsal view petiole node broader than long.

The Sumatran specimens are approximately HL 0.90, HW 0.69, CI 77, ML 0.38, MI 42, SL 0.46, SI 67, PW 0.42, AL 0.88.
