Description
Worker
Holotype. TL 2.5, HL 0.61, HW 0.43, CI 70, ML 0.28, MI 46, SL 0.40, SI 93, PW 0.26, AL 0.64. 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 angled anteriorly nor looped. With head in full-face view the dorsolateral margin posterior to the flagellate apicoscrobal hair has a series of 2-3 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 cephalic dorsum almost reclinate, in profile not elevated, each hair strongly curved basally and main length of hair-shaft parallel to the surface or even inclined or curved back down toward the surface. Ground-pilosity on pronotal dorsum sparse and dilute, not appearing as a pelt. Dorsum and side of pronotum entirely reticulate-punctate. Dorsum of pronotum 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 lamella. Propodeal teeth visible at dorsal apex of lamella but entirely confluent with it. Disc of postpetiole unsculptured. Basigastral costulae conspicuous but not extending half the length of the tergite.
Paratypes. TL 2.4-2.5, HL 0.59-0.62, HW 0.41-0.43, CI 67-71, ML 0.28-0.30, MI 45-48, SL 0.38-0.41, SI 90-95, PW 0.24-0.26, AL 0.62-0.65 (8 measured).
