Types. Male holotype and male and female paratypes from 0.6 m west of Elk City, Yaquina River, 44.6233°, - 123.8918°, Lincoln Co., Oregon, collected 20 December 1971 by E. M. Benedict. All types deposited in CAS.
Diagnosis. Distinct from other species of the genus in having an unenlarged, straight epiproct (Fig. 113) and four rows of setae on the anterior metazonites (Fig. 112), increasing to five rows on the most posterior rings (Fig. 113).
Etymology. The species epithet, a noun in apposition, refers to the type locality along the Yaquina River.
Description. Holotype male. Nineteen rings (Fig. 111; the telson or 19th ring is concealed in the figure by the crassate anterior legs). Length about 5.5 mm, greatest width 0.62 mm. Head densely setose, cuticle alveolate (Fig. 112). Collum with anterior marginal row of 20 setae (Fig. 112). Anterior metazonites with four rows of setae, transitioning to four rows (Fig. 113) about ring 15, setal tubercles prominent throughout. Alveolate cuticle absent from metazonites posterior to collum. Epiproct (Fig. 114) not swollen, relatively long, straight, with extensive alveolate cuticle. Anterior legs crassate (Fig. 111), tarsi with sphaerotrichomes. Gonopod (Figs 115–117, 135) with rather flattened prefemorite. Acropodite short, robust. Pulvillus (p, Fig. 116, 117) just distal to midlength of acropodite, somewhat elongate. Pulvillar process (pp, Fig. 116, 117) with short tooth on lateral side. Terminal zone entire (tz, Fig. 116, 117), with distinct apical tooth. Females similar to males in nonsexual characters.
