Material examined. Oregon: Lane Co.: Small spring at mouth of Tenmile Creek , 30-Jan-00, coll. S. Fend, 1 whole mount . Washington: Jefferson Co.: small seep along Hoh River, 29-Apr-99, coll. S. Fend, 1 whole mount. Small tributary to Clearwater River at Coppermine Bottom Camp, 25-Apr-04, coll. S. Fend, 1 whole mount . Idaho: Valley Co.: South Fork Salmon River at Shiefer Camp, 25-Aug-05 coll. D. Gustafson, 2 whole mounts. Twin Falls Co. : Salmon Falls Creek , Castleford Branch, 28-Mar-03, coll. D. Gustafson, 3 dissected .
Remarks. The three specimens from coastal Oregon and Washington all resemble A. freidris , but have extremely long, extended penes ( Fig. 11D–F). As penial extension in preserved worms is highly variable, and related to fixation, this may not be a basis for distinguishing a separate species using such limited material.
The few specimens from Salmon Falls Creek in southern Idaho ( Fig. 11A–B) appeared somewhat intermediate between A. freidris and A. idahoensis . The atrial ampullae were relatively short, penial structures were narrow and indistinct, and extruded penes narrow and straight. This may represent yet another species, but the poor condition of the limited material does not permit an adequate description. Only two specimens were available from the South Fork Salmon River site in northern Idaho, but both had unusually thin penial structures and very small atria ( Fig. 11C).
