Closely resembling Nylanderia rosae of Australia in form and sculpture but of very different color. Head broadItalic texter, with more convex eyes and distinctly concave posterior border; antennal funiculi longer and more slender; base of epinotum more convex and rounded. Petiolar node with more rounded and less truncated superior border, inclined forward as in rosae. Gaster anteriorly with a deep concavity for the accommodation of the petiole. Yellow, with jet black gaster; anal segment reddish. Smooth and shining. Pilosity much as in rosae, with the erect hairs long and coarse, but longer and more numerous on the mesonotum and sides of the pronotum. The hairs are dark brown but appear partially pale in some lights. Pubescence on epinotum and legs rather conspicuous, white and appressed.
