Nothing is known about the biology of .

Identification
Bolton (2000) - A member of the lyroessa complex in the Strumigenys lyroessa-group. S. micrura appears closest related to Strumigenys imantodes (see notes under Strumigenys arrogantia). However, compared to imantodes, micrura is much darker in colour, distinctly larger (compare measurements) and has a petiole node that in dorsal view is about as broad as long rather than being transversely rectangular.

Worker
Holotype. TL 2.7, HL 0.79, HW 0.61, CI 77, ML 0.22, MI 28, SL 0.34, SI 56, PW 0.36, AL 0.74. Characters of lyroessa-complex. In profile preapical tooth of mandible stouter and more strongly developed than apicodorsal tooth. Upper scrobe margin with a row of anteriorly curved small spatulate to narrowly spoon-shaped hairs. Apicoscrobal hair short, stiff and stout; dorsolateral margin of occipital lobe posterior to this with 4-6 similarly shaped but slightly shorter projecting hairs. Cephalic dorsum with standing hairs restricted to a stubbly transverse row along the occipital margin. Pronotal humeral hair short and stiff; pronotum otherwise without standing hairs. Mesonotum with 3 pairs of remiform to apically expanded short erect hairs, located along the dorsolateral margins. Lamella on propodeal declivity fine and narrow, with a shallowly concave free (posterior) margin; maximum width of lamella below level of spiracle is distinctly less than half the length of the propodeal tooth. Petiole node in dorsal view about as broad as long, not transversely rectangular. Erect hairs on first gastral tergite short and stiff, spatulate or expanded apically, distributed over the entire sclerite. Entirety of head and body black to blackish brown, more darkly coloured than is usual in the group.

Paratypes. TL 2.5-2.7, HL 0.77-0.80, HW 0.60-0.62, CI 77-79, ML 0.22-0.23, MI 27-29, SL 0.32-0.34, SI 53-55, PW 0.34-0.38, AL 0.72-0.75 (3 measured).
