This rainforest species is known from a limited number of collections from a small area of the wet tropics, northern Queensland. It has been collected from leaf litter samples.


Shattuck (2009) - Sculpturing on anterior mesonotum consisting of continuous transverse “U”-shaped carinae, the area immediately behind the pronotal collar weakly sculptured or essentially smooth. This species is most similar to Myrmecina eruga and Myrmecina pumila in having weakly developed sculpturing on the pronotum immediately behind the collar but differs in having transversely arched (rather than longitudinal) carinae on the dorsum of the mesosoma.
