Coxa and femur with few very short hairs; tibiae with long, thick semi-erect squamiform hairs on the inner surface, external face of the tibiae devoid of erect hairs, with only a few long, flattened hairs located apically. First gastral tergite largely devoid of setae, with 2 - 3 squamiform setae at posterolateral margins. Head, mesosoma, petiole and postpetiole shagreened, with the surface strongly areolate (Fig. 9); surface of first gastral tergite areolate. Color ocher to orange, concolorous. Queen and male.
