Oregon: Union Co., Blue Mts., Phillips Creek Road, 9 km NW Elgin (2, CNC).

Diagnosis.

As given above for the genus.

Redescription.

The species was redescribed by Smetana (1971a) but this is here supplemented with additional characters specific to the male and female: male with sternite VII unmodified; sternite VIII with broad shallow emargination; tergite X constricted in apical half, with weakly emarginate apex, apical half with short fine setae on lateral parts of disc and strong, coarse setae along apical margin (Fig. 3E View Figure 3 ); sternite IX with moderately slender, asymmetrical base, elongate with deep and narrow emargination (Fig. 3F View Figure 3 ); median lobe of aedeagus in ventral view narrowed to sharp apex, apical portion with longitudinal median excavation (Fig. 3B View Figure 3 ), paramere with broad base, with elongate triangular apical part and narrow apex (Fig. 3B View Figure 3 ); aedeagus in lateral view with paramere swollen, slightly deflexed dorsad, median lobe sinuate, narrow, with fin-like apex (Fig. 3C View Figure 3 ); apex of paramere with longitudinal, median cluster of peg setae, extended basad on slight ridge (Fig. 3D View Figure 3 ). Female with tergite X narrowly elongate, with two-pronged apex, prongs separated by U-shaped emargination (Fig. 3G View Figure 3 ).

Distribution.

Canada: BC. United States: CA, ID, NV, OR, WA

Bionomics.

Smetana (1971a, b) reported this species from debris near water, especially along larger creeks and rivers. Longer series were found in river drift left behind after periods of high water levels. Several specimens have been found in beaver houses, but it is not known whether they regularly occur there.

Comments.

The paratype specimens mentioned by Hatch (1957) from Lenore, Idaho and Pullman, Washington were not examined but indicate this species’ distribution is rather broad across the entire Western Cordillera. The occurrence of F. elevatus along large river banks at a wide range of elevations suggests a single broadly distributed species. Specimens from California were paler than most of those from British Columbia and Oregon but no consistent differences were observed in the aedeagus.
