Galena Creek, Galena Creek Park, 24 June 2009, B. Stark, C. R. Nelson, K. Nye, A. Harrison, 3♂, 16♀ (BPS). Male epiproct. Total length ca. 500-530 ��m, basal width ca. 125-150 ��m, greatest width ca. 245-250 ��m. Epiproct saggitate in dorsal aspect with thick tip slightly upturned and bearing narrow groove which extends from base to ca. 90-110 ��m from apex (Figs. 19-22). Dorsal surface bearing short, multifilament setae (Fig. 23); ventral surface glabrous. Dorsal process. Located on tergum 9. Total width ca. 160-180 ��m, median notch shallow with truncate floor, notch width ca. 80-90 ��m. Lobes of process triangular in outline (Fig. 24). Comments. The epiproct and dorsal process were illustrated by Ricker (1952). Surdick (1995) presented dorsal, dorsolateral and fully lateral outlines of this structure. More recently Lee & Baumann (2010) included five SEM images of the S. townesi epiproct in their redescription of that species. Surdick (1995) considered S. townesi and S. resima as sister species but data from the description and placement of S. salix in this group suggest S. townesi and S. salix are the more closely related pair (Lee & Baumann 2010). Unfortunately, no support for either of these hypotheses is available from our limited study.
