The described preserved female specimens have an oval back with purple colour at the rear.
On 6 August 1987, one male was collected in a small cascading trickle beside a road in Trinity County, California, USA.
In these female specimens, the base supporting the mouthparts is elongated and colourless, and the rostrum is elongated. The mouthparts have curved fangs.
In these females, the palps are elongated. Their femur segments have broad, flat, toothed projections pointing forward underneath; the following genu segments have broad, bumpy, toothed projections underneath.
