In females, the band is located approximately halfway between the antennae and ocelli, and is either narrowly or widely spaced medially.

In some cases, the antennae may be completely black, with the third joint sometimes having a slight reddish hue at its base.

The occiput is dark, with a light coating of pollen, and the pile is a bright brownish yellow.

The scutum of the thorax is dark, and may even appear to be shiny or metallic, and is covered with light pile.

On the second segment, there are two oblong yellow spots that do not reach the lateral margin.

The stigma is elongated, and the lower lobe of the calypter has only microscopic pile above.
