Not much is known about this species. It has been collected from rainforest and primary forest.
Identification
Bolton (2000) - A member of the Strumigenys appretiata-group. Closest related to Strumigenys raptans but in that species basigastral costulae are sharply developed and distinct, the petiole node is longer than broad and the spongiform lobes of the postpetiole are larger and better developed . For separation from other closely related species (Strumigenys glenognatha, Strumigenys wheeleriana) see under those names.

Description
Worker
Holotype. TL 2.0, HL 0.56, HW 0.50, CI 89, ML 0.10, MI 18, SL 0.20, SI 40, PW 0.28, AL 0.58. Pronotum and most or all of mesonotum smooth and shining. Pronotal humeral hair long, flagellate. Hairs on first gastral tergite long and fine, strongly curved, flexuous to sub flagellate. Petiole node in dorsal view broader than long, its dorsum smooth and shining. Lateral lobes of petiole node small in dorsal view, appearing as bluntly triangular translucent lamellae. Spongiform appendages of postpetiole relatively small; in dorsal view width of one lateral lobe less than one-quarter the width of the disc. In profile ventral lobe of postpetiole reduced , restricted to anterior half (approximately) of sternite and its maximum depth distinctly less than half the depth of the segment. Basigastral costulae vestigial to absent, usually extremely faint and minute. First gastral tergite smooth and shining.
Paratypes. TL 0.20, HL 0.56-0.58, HW 0.50, CI 86-89, ML 0.10, MI 17-18, SL 0.20, SI 40, PW 0.26-0.28, AL 0.57-0.58 (2 measured).
