Known only from the holotype, nothing is known about this ant's biology.
Identification
Terayama & Yamane (2000) - This species is distinguished from Lasiomyrma gedensis by the straight propedeal dorsum, the absence of an angle of anterior slope of petiolar node and the concave occipital margin of head in full face view, and from Lasiomyrma maryatiae by the thinner petiolar node, the shorter mesopleuron and the weakly produced propodeal lobe.
