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 gracilinoda by the thicker petiolar node, the longer mesopleuron and the strongly produced propodeal lobe.
