Anal region reddish. Gaster and terminal funicular joints dark brown. The clavate hairs on the head, thorax, and gaster are as long as in the var. spicata but more numerous on the posterior portion of the pronotum and the whole of the mesonotum. Gula with a very few erect hairs. Pubescence very fine and indistinct, except on the gaster. There are no oblique or suberect hairs on the scapes or legs. The body, including the legs and gaster, is smooth and slightly shining, the frontal area subopaque.
