Nomenclature

 *  reliquia. Smithistruma reliquia Ward, 1988: 117, fig. 7 (w.) U.S.A. Combination in Pyramica: Bolton, 1999: 1673; in Strumigenys: Baroni Urbani & De Andrade, 2007: 126. See also: Bolton, 2000: 110.

Worker
Bolton (2000) - TL 2.1-2.2, HL 0.58-0.62, HW 0.38-0.40, CI 65-67, ML 0.09-0.10, MI 16-18, SL 0.33-0.34, SI 83-87, PW 0.24-0.26, AL 0.58-0.61 (3 measured).

First (basal) tooth on mandible much shorter than second; diastema between basal lamella and basal tooth longer than length of basal tooth. Anterior clypeal margin evenly smoothly convex; clypeal dorsum densely reticulate-punctate. Eye with 3-4 ommatidia in longest row. Propodeal dorsum with punctate sculpture partially effaced. Entirety of body pilosity simple and fine, filiform to flagellate; without spatulate, spoon-shaped or other bizarre pilosity anywhere. Hairs on anterior clypeal margin shallowly curved away from midline; on lateral margins inclined anterolaterally or feebly recurved; on clypeal dorsum fine hairs elevated, subdecumbent to suberect at least in their apical halves. Leading edge of scape with most hairs curved toward apex of scape but one or two of the longer hairs, close to the subbasal bend, curved toward the base of the scape. Dorsolateral margin of head with 2 long fine laterally projecting flagellate hairs; one apicoscrobal, the other anterior to this. Cephalic ground-pilosity curved-filiform, very fine; close to occipital margin with a transverse row of 4 more erect hairs that are longer and even finer, subflagellate or looped. Dorsal alitrunk with pronotal and mesonotal pairs of long flagellate hairs. Long curved sinuous to flagellate hairs also present on waist segments and first gastral tergite. Dorsal (outer) surface of hind tibia and basitarsus with projecting long flagellate hairs.
