Figs 19–26 View FIGURES 16–23 View FIGURES 24–29
Types: Male holotype and female paratype from the O’Hara Bar Campground on the Selway River, Nez Percé National Forest, Idaho Co., Idaho, USA, 46.08521°N, - 115. 51761°W, 1600’ asl, collected 14 October 2006 by C. Richart, W. Leonard and A. Fusek. The male holotype and female paratype are mounted on SEM stub WS36-18. GoogleMaps An additional female paratype is from the same locality, but collected 2 April 2003 by W. Leonard, J. Bough and J. Degenhardt. All types including SEM stubs deposited in the California Academy of Sciences , San Francisco, California, USA GoogleMaps .
Etymology: The species epithet is a noun in apposition, after the type locality.
Diagnosis: See the diagnosis of the genus, above. This is the only known species.
Description: Male holotype. Length, ca. 4.5–5.0 mm, width ca. 0.4–0.5 mm. Twenty-nine thoracic rings, including telson.
Head densely setose, with minimal pebbled sculpture. Antennae as usual for family. Two black ommatidia on either side of head. Labrum without lateral processes. Mandibular stipes with slight serrate distal edge, lacking acute posteriodistal corner.
Collum with distinct pebbled sculpture throughout, crests low, inconspicuous, restricted to posterior half; collum with distinct anteriolateral notches on each side, from which originate lateralmost segmental setae ( Fig. 24 View FIGURES 24–29 ). Collum with long, acute segmental setae, but such setae not detectable on more posterior trunk rings. Rings 2 and 3 with subequal but prominent crests. Rings 4–6 with both second and third crests exaggerated; second crests the highest, divergent ( Fig. 25 View FIGURES 24–29 ). From ring 7 posterior, third crest returns to normal size while sixth crest becomes slightly larger ( Figs 26, 27 View FIGURES 24–29 ).
Telson with lobes not separated by deep incisions, without crests ( Figs 25, 26 View FIGURES 24–29 ).
First, second and third legpairs subequal in size, first legpair with long setae, third coxae with moderately developed coxal flasks. Second leg prefemor (tr2, Fig. 19 View FIGURES 16–23 ) with prominent setose process (ptr, Fig. 19 View FIGURES 16–23 ), coxa with vas deferens opening at tip of short process, membranous but with small, scale-like setae ( Fig. 20 View FIGURES 16–23 ). Fourth to seventh legpairs encrassate. Seventh legpair without coxal lobes.
Gonopods ( Figs 21, 22 View FIGURES 16–23 ) very small. Sternum (s, Figs 21, 22 View FIGURES 16–23 ) prominent, with deep medial embayment. Coxae (cx, Fig. 21 View FIGURES 16–23 ) with array of about 6 stout setae. Anterior angiocoxite (aac, Figs 21, 22 View FIGURES 16–23 ) not divided, tipped with array of fine cuticular projections. Posterior angiocoxite reduced, sheathing at least two flagellocoxites (fc, Fig. 21 View FIGURES 16–23 ). Colpocoxite apparently reduced, posterior part with fimbriate branches (cc?, Fig. 22 View FIGURES 16–23 ). Ninth legs with all elements free, telopodite (t9, Fig. 23 View FIGURES 16–23 ) flattened, heavily pebbled.
Female paratype. Similar to male, but second crests much lower on posterior segments than in male ( Fig. 28 View FIGURES 24–29 ).
