Identification
Bolton (2000) - A member of the signeae complex in the Strumigenys godeffroyi-group. This arboreal species is unique in the group because of the dense silky longitudinal striolate-punctulate sculpture that entirely blankets the first gastral tergite. See notes under Strumigenys forficata.

Description
Worker
Holotype. TL 2.6, HL 0.79, HW 0.62, CI 78, ML 0.33, MI 42, SL 0.44, SI 71, PW 0.29, AL 0.68. Characters of signeae-complex. Preapical tooth very close to apicodorsal tooth. Dorsolateral margin of head in full-face view with a row of minute, closely applied spoon-shaped hairs, without an apicoscrobal hair. Ventrolateral margin of head concave in front of eye. Cephalic dorsum with appressed, very narrowly spatulate ground-pilosity but without erect hairs, even lacking the usual row near the occipital margin. Dorsal alitrunk with sparse appressed ground-pilosity, without standing hairs anywhere, without a pronotal humeral hair. Dorsal surfaces of petiole, postpetiole and first gastral tergite without standing hairs; second tergite to apex with a few short erect hairs. Entire dorsum and side of alitrunk densely reticulate-punctate. Propodeal lamella very narrow, engaging only extreme base of spine. With petiole in profile the lateral spongiform lobe is restricted to the posterior third of the length of the node; in the same view anterior face of node is slightly shorter than length of dorsum. Petiole node in dorsal view broader than long. Disc of postpetiole finely reticulate-punctulate. First gastral tergite entirely covered with fine dense longitudinal striolate-punctulate sculpture that gives the sclerite a silky appearance. Base of first gastral sternite without spongiform tissue.
Paratypes. TL 2.6, HL 0.79-0.80, HW 0.61-0.62, CI 76-78, ML 0.33-0.34, MI 41-43, SL 0.44, SI 71-72, PW 0.28-0.29, AL 0.68-0.70 (2 measured).
