Types: Male holotype and male paratype from Tiger Creek, Umatilla National Forest,
45.9800500, -118.0522833 °, 2417’ asl, Umatilla Co., Oregon, collected 24 October 2003 by W. Leonard; additional male paratype from same locality, but 45°58.685’, -118°03.137’. Parts of these specimens are mounted on SEM stub WAS34-11.
Diagnosis: Distinct in the form of the gonopods (Figs. 37, 54, 55), and in the angular, overlapping median termini of the pleurotergal bars of ring 7 (Fig. 35).
Etymology: The species name, a noun in apposition, is from the Umatilla National Forest and Umatilla County, Oregon.
Description: Male holotype. Length, about 11 mm, width 1.0 mm. Five ommatidia in two rows. Labrum with long, slightly sinuous hooks at each angle. Mandibles not modified. Legpairs 1 and 2 similar in size (Fig. 35); legpair 1 without needle-like long setae, tarsi with spatulate, twisted setae ventrally. Second trochanters with moderate posteriorventral processes, bearing groups of specialized setae. Legs 3 with coxal flasks long, asetose, diverging; prefemora distally expanded, telopodites not strikingly reduced (Fig. 35). Pleurotergal bars of ring 3 expanded, angular distally, overlapping in midline. Crests moderate. Pygidium short. Color uniform medium brown.
Gonopod (Figs. 37, 54, 55) anterior angiocoxites with broad, two-toothed lateral process, smaller teeth distally on posterior surface. Posterior angiocoxites narrow at origin, broadening distally, sheathing 3 or possibly 4 long flagellocoxites. Ninth legpair with small distal coxal process, flattened telopodites articulating loosely with depression on pleural margin of ring 7 (Fig. 36).
Females not collected.
Distribution: Known from the two close-by localities listed under Types.
