Worker
Bolton (2000) - TL 2.0-2.2, HL 0.55-0.59, HW 0.38-0.42, CI 67-73, ML 0.24-0.27, MI 43-48, SL 0.32-0.34, SI 79-87, PW 0.24-0.27, AL 0.58-0.62 (16 measured).

Characters of godeffroyi-complex. Cephalic dorsum with pair of erect hairs closest to midline on occipital margin short stiff and erect, straight to shallowly evenly curved but the apical half not abruptly curved anteriorly nor looped. With head in full-face view the dorsolateral margin posterior to the flagellate apicoscrobal hair has a row of 3-4 stiffly projecting hairs. These hairs contrast with the marginal hairs anterior to the flagellate hair as they are more cylindrical (i.e. not spatulate), more elevated and less strongly curved anteriorly. Ground-pilosity on pronotal dorsum sparse and dilute, not appearing as a pelt. Dorsum and side of pronotum smooth and shining (when clean), frequently completely without punctate sculpture. Dorsum of pronotum with a pair of erect flagellate hairs in addition to the humeral pair. Pleurae and side of propodeum mostly to entirely smooth, any reticulate-punctate sculpture present is confined to periphery. Propodeal declivity with a broad and very conspicuous lamella. Propodeal teeth at most only weakly expressed (may be vestigial), entirely confluent with the lamella and surmounted by a narrow convex crest of spongiform tissue. Disc of postpetiole unsculptured. Basigastral costulae conspicuous but not extending half the length of the tergite.

Type Material
