Nomenclature

 *  trudifera. Strumigenys trudifera Kempf & Brown, 1969: 18, figs. 1-3 (w.q.) BRAZIL. See also: Bolton, 2000: 568.

Worker
Bolton (2000) - TL 3.0-3.4, HL 0.68-0.72, HW 0.44-0.48, CI 65-68, ML 0.78-0.89, MI 110-120, SL 0.48-0.56, SI 108-117, PW 0.29-0.32, AL 0.65-0.72 (10 measured). In full-face view upper scrobe margins divergent from frontal lobes to level of eyes, then passing through an angle and thereafter more or less parallel to their apices. In same view the posterior portion of the ventrolateral margin of the head is visible beyond the line of the scrobe. Eye small, with 6-8 ommatidia in total. Funicular segments all elongate and narrow, segments 2 and 3 much longer than broad. Flagellate hair at pronotal humerus arising from a distinct tubercle. Dorsal surfaces of middle and hind legs without gland bullae. Petiole with a long slender peduncle, the node in dorsal view reticulate-punctate, slightly longer than broad and without a spongiform posterior collar. In profile lateral lobe of petiole node small to minute and ventral spongiform strip variably developed, sometimes mostly or entirely absent. Disc of postpetiole reticulate-punctate to almost smooth. Basigastral costulae sparse but sharply defined, longer than disc of postpetiole; spaces between costulae superficially sculptured.
