Strumigenys geminata

Nothing is known about the biology of .

Identification
Bolton (2000) - A member of the godeffroyi complex in the Strumigenys godeffroyi-group. See notes under Strumigenys godeffroyi. This Malaysian species is very close to Strumigenys lewisi of China, Japan and Taiwan. The two separate by size (compare measurements) and a few other details. The propodeal teeth are relatively longer, more strongly developed and more clearly visible in geminata than in lewisi. Side of pronotum is extensively smooth in geminata whereas in lewisi it tends to be completely reticulate-punctate or at most to have a small smooth patch above the fore coxa.

Worker
Holotype. TL 2.0, HL 0.54, HW 0.38, CI 70, ML 0.26, MI 48, SL 0.32, SI 84, PW 0.24, AL 0.53. 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, 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 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 of pronotum reticulate-punctate, side with an extensive smooth unsculptured patch. 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 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 2.0, HL 0.54-0.55, HW 0.37-0.40, CI 69-73, ML 0.25-0.26, MI 46-48, SL 0.30-0.32, SI 79-86, PW 0.23-0.24, AL 0.51-0.53 (5 measured).

Dimensions of non-paratypic workers. HL 0.54-0.62, HW 0.38-0.43, CI 69-73, ML 0.25-0.30, MI 46-50, SL 0.30-0.37, SI 79-86.
