Descriptions(1)
So far this species is known only from the Pacific Northwest region bordering the Juan de Fuca and Georgia Straits (Olympic National Park, Washington, and Garibaldi Provincial Park, British Columbia, respectively). It was collected from moss along mountain streams and waterfalls. The species is recognised by its markedly prognathous head (Fig. 3 A), abundant anterior setae on the ventral tube (more than 10 on each side), apical tooth of mucro much larger than subapical tooth (Fig. 6 B), slender claws, and normal, thin, setae on the body.
