ABSTRACT. One new ant species of the subfamily Myrmicinae, Indomyrma bellae sp.n. is described from Cat Tien National Park (Southern Vietnam) based on workers and dealate queen. The genus Indomyrma was hitherto known only from one species, I. dasypyx Brown, 1986, described from two localities of the Southwestern India. A new species differs from I. dasypyx in the worker and queen by smaller body size, reduction of erect hairs on alitrunk, petiole and postpetiole, shape of anterodorsal margin of  pronotum and petiolar node, features of the sculpture and strongly reduction (only 2–3 ommatidia) of eye in workers. The sting apparatus of genus Indomyrma is described for the first time. Biogeography analysis of the genus Indomyrma is given.
