Worker
Bolton (2000) - TL 2.0, HL 0.52-0.54, HW 0.37-0.30, CI 69-74, ML 0.18-0.20, MI 35-38, SL 0.28-0.30, SI 74-77, PW 0.22-0.23, AL 0.54-0.56 (4 measured). Characters of godeffroyi-complex. Cephalic dorsum with pair of erect hairs closest to midline on occipital margin fine, basal portion of hair erect and apical third or more abruptly angled or hooked anteriorly, or looped. With head in full-face view the dorsolateral margin posterior to the flagellate apicoscrobal hair without 3-4 stiffly projecting hairs; either without such hairs at all or at most with a single stiff hair immediately posterior to the flagellate hair. When a single such hair occurs it contrasts strongly with the marginal hairs anterior to the flagellate hair, being more cylindrical (i.e. not spatulate), more elevated and less strongly curved anteriorly. Ground-pilosity on pronotal dorsum short and sparse, not forming a dense pelt. Dorsum of pronotum reticulate-punctate and 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 spongiform lamella, the propodeal teeth only weakly expressed (may be vestigial) and entirely buried in the lamella. Dorsal surface of propodeal tooth in profile surmounted by a convex crest or ridge of spongiform tissue. In dorsal view petiole node un sculptured; lateral margins of node converge anteriorly and terminate in an anteromedian blunt point so that shape of dorsum of node is roughly triangular; lateral spongiform lobes extend anteriorly to, or almost to, the apex of the anteromedian point. Disc of postpetiole unsculptured. Basigastral costulae conspicuous but not extending half the length of the tergite.
