The pleurae are shining greenish black, and there is an oval yellow spot on the meso-pleurae, as well as a smaller and more whitish one below it, narrowly separated.

The propleuron and anepimeron are entirely black, and the hairs on the anterior anepisternum of the female are extremely short and scarcely discernible.

The legs are mostly yellow, while the hind femora are black, except at the base, which is less extensive in the female, often only appearing as a brown ring.

The third and fourth segments have a slender median stripe that is wider toward the front and a pair of large spots on the anterior margin that are dilated behind on the ends.

The fourth segment is rather deeply marginate on each side behind and the ends are rounded and extend backward.
