Nomenclature

 *  prospiciens. Strumigenys smithi subsp. prospiciens Emery, 1906c: 167, fig. 26 (w.) ARGENTINA. Brown, 1953f: 109 (q.). Junior synonym of smithii: Forel, 1911e: 263; of mandibularis: Emery, 1924d: 322. Revived from synonymy and raised to species: Brown, 1953f: 108. See also: Bolton, 2000: 537.

Worker
Bolton (2000) - TL 3.1-3.3, HL 0.75-0.81, HW 0.60-0.64, CI 76-80, ML 0.42-0.45, MI 53-57, SL 0.50-0.56, SI 82-88, PW 0.39-0.44, AL 0.80-0.87 (10 measured).

Characters of mandibularis-complex. Proximal preapical tooth located about at the midlength of the inner mandibular margin; may be exactly at midlength or fractionally proximal or distal of it. Proximal preapical tooth usually longer than distance separating it from distal preapical tooth. Outer margin of mandible moderately curved outward at full closure. Propodeal declivity in profile short, with an upper and a lower tooth or lobe, one or both of which may be triangular or low and blunt; the two approximated and linked by a short lamella. Disc of postpetiole reticulate-punctate, approximately as broad as long to broader than long. First gastral tergite with fine flagellate hairs arising all over the sclerite, not restricted to basal third or less. Basigastral costulae absent or at most so tiny that they scarcely project beyond the limbus.

Type Material
Bolton (2000) - Holotype worker, ARGENTINA: Misiones, Puerto Piray (F. Silvestri) [not seen].
