An anterior view of the front legs displays the colour and number of pecten spines, and the shape of the basitarsus itself (arrows). In this female the basitarsus is long and slender (not broadly expanded), mostly yellow but with a darkened outer edge, weakly lobed at the base of the spines. The six spines are long, and amber in colour.

The clypeus in this female is elevated mediobasally (star).
