Strumigenys uberyx

Known from the two type workers, nothing is known about the biology of .

Identification
Bolton (2000) - A member of the godeffroyi complex in the Strumigenys godeffroyi-group. In the godeffroyi-complex this species, Strumigenys eumekes and Strumigenys juliae are notable for their lack of pronotal sculpture, both dorsally and laterally. However, eumekes has posterior cephalic pilosity like nanzanensis (see there). S. uberyx is smaller than juliae and has much smaller eyes and coarser fringing pilosity on the upper scrobe margin. The propodeal lamella of uberyx is narrower and less obviously spongiform than in juliae, and there is no spongiform crest on the dorsal surface of the propodeal tooth. For broader associations see notes under godeffroyi.

Worker
Holotype. TL 1.8, HL 0.48, HW 0.32, CI 67, ML 0.20, MI 42, SL 0.29, SI 91, PW 0.20, AL 0.52. Characters of godeffroyi-complex. Cephalic dorsum with pair of erect hairs closest to midline on occipital margin short stiff and erect, 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 lacks stiffly projecting hairs. Eye minute, with only 3-4 ommatidia in total. In full-face view curved hairs on upper scrobe margin stout, narrowly spoon-shaped; eye not at all visible in this view. Ground-pilosity on pronotal dorsum sparse and dilute, not appearing as a pelt. Dorsum and side of pronotum smooth and shining (when clean), without reticulate-punctate sculpture. Dorsum of pronotum with a pair of erect flagellate hairs in addition to the humeral pair (broken off short in holotype, visible in paratype). Pleurae and side of propodeum smooth. Lamella on propodeal declivity with a shallowly convex posterior (free) margin, its maximum width in profile slightly more than length of propodeal tooth. Lamella restricted to ventral surface of propodeal tooth, the latter not surmounted by a convex crest of spongiform tissue. Disc of postpetiole unsculptured. Basigastral costulae conspicuous but not extending half the length of the tergite.

Paratype. TL 1.9, HL 0.49, HW 0.33, CI 67, ML 0.20, MI 41, SL 0.21, SI 88, PW 0.21, AL 0.50.
