Description
Worker
Holotype. TL 2.6, HL 0.66, HW 0.43, CI 65, ML 0.38, MI 58, SL 0.45, SI 105, PW 0.26, AL 0.68. 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 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. Inner margin of mandible approximately straight from base to about two-thirds of its length, the mandible slightly increasing in width along this length; inner margin distal of this angling outwards to the preapical tooth so that mandible gradually narrows. Ground-pilosity on pronotal dorsum sparse and dilute, inconspicuous. Dorsum and side of pronotum reticulate-punctate and with a pair of erect 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. Disc of postpetiole unsculptured. Basigastral costulae conspicuous but not extending half the length of the tergite.
Paratypes. TL 2.6, HL 0.66-0.68, HW 0.42-0.44, CI 63-65, ML 0.38-0.39, MI 56-58, SL 0.45-0.46, SI 105-107, PW 0.26-0.27, AL 0.68-0.70 (5 measured).
The non-paratypic material is slightly larger, HL 0.71, HW 0.45, CI 63, ML 0.40, MI 56, SL 0.48, SI 107.
