Identification
Bolton (2000) - A member of the signeae complex in the Strumigenys godeffroyi-group. Density and intensity of sculpture on disc of postpetiole may be variable here, as in Strumigenys sytaria. See notes under Strumigenys mocsaryi.

Description
Worker
Holotype. TL 2.5, HL 0.70, HW 0.52, CI 74, ML 0.28, MI 40, SL 0.38, SI 73, PW 0.30, AL 0.71. Characters of signeae-complex. Apicoscrobal hair weakly remiform; dorsolateral margin of head posterior to this with 2-3 similar but shorter projecting hairs. Cephalic dorsum with a transverse row of 4-6 erect hairs at occipital margin; without standing hairs anterior to this. Pronotal humeral hair stiff and straight, long-spatulate to weakly remiform; pronotal dorsum otherwise without erect hairs. Mesonotum with a single pair of stout erect hairs. Entire dorsal alitrunk reticulate-punctulate. Katepisternum mostly smooth but side of alitrunk otherwise entirely reticulate-punctate. Lamella on propodeal declivity concave immediately below tooth but lower on declivity forming a broadly convex lobe. Petiole node in dorsal view slightly broader than long, reticulate-punctate. In profile lateral spongiform lobe of petiole small, confined to posterolateral portion of node; height of anterior face of node less than length of dorsum. Disc of postpetiole almost unsculptured centrally, with only traces of feeble superficial punctulae; periphery of disc with sculpture more obvious. First gastral tergite with weakly remiform stout standing hairs. Basigastral costulae shorter than disc of postpetiole.
