Strumigenys exunca

Identification
Bolton (2000) - Most closely related to the southern African Strumigenys robertsoni but distinguished by the reduced sculpture of the lateral alitrunk and numerous simple standing hairs close to the occipital margin that contrast strongly with the ground-pilosity.

Distribution based on Regional Taxon Lists

Worker
Holotype. TL 2.3, HL 0.65, HW 0.39, CI 60, ML 0.10, MI 15, SL 0.30, SI 77, PW 0.25, AL 0.64. Characters of emarginata-complex. With head in full-face view ground-pilosity of the dorsum of numerous small spoon-shaped hairs that are very conspicuous; these hairs slightly denser on the clypeal dorsum than elsewhere. Lateral margin of occipital lobe without projecting simple hairs but a n umber of curved spoon-shaped hairs may project beyond the outline. In profile the spoon-shaped ground-pilosity very distinct from clypeus to highest point of vertex but behind this with numerous finer simple hairs that are erect and weakly curved anteriorly, contrasting strongly with the ground-pilosity. Pronotal dorsum with distinct curved spoon-shaped hairs only. Mesonotum with very sparse spoon-shaped ground-pilosity and with 3-4 pairs of long standing hairs that are simple, slightly flattened or weakly remiform, and usually shallowly curved. Pleurae and side of propodeum with extensive smooth shining areas. Pronotal dorsum weakly sculptured, usually with faint longitudinal striae visible. Propodeal dorsum with vestiges of punctate sculpture.

Paratypes. TL 2.3-2.5, HL 0.64-0.70, HW 0.38-0.41, CI 59-61, ML 0.10-0.12, MI 15-18, SL 0.30-0.32, SI 77-80, PW 0.25-0.28, AL 0.64-0.70 (10 measured).
