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 .
