Male epiproct. Stark & Gustafson (2004) presented an image (Fig. 19 in Stark & Gustafson) of the epiproct from Glenn County specimens in which the epiproct stem gradually becomes wider near the apex and the lateral margins of the anterior face do not extend beyond those of the stem. In addition, the anterior face was 252 μm wide and heavily armed with a total of 37 marginal and submarginal teeth in 3+ rows. The specimen of S. thyra in our study from Napa County ( Figs. 6-7 View Figs ) has the anterior face distinctly wider than the stem (175 μm, but narrower than that of the Glenn County specimen) and has smaller and far fewer (21) teeth.
Male aedeagus. Stark (1983) described and illustrated this distinctive structure from the holotype and from Napa County specimens. Herein, we provide additional images of the structure from a Humboldt County specimen. In all specimens examined by us, the ventral surface of the aedeagus bears a pair of prominent, curved spines that arise from sclerites ( Fig. 12 View Figs ). Additional small setal spines occur along the anterolateral margins ( Fig. 13 View Figs ).
Larval abdominal pigment patterns. Stark (1983) described the larva of this species from Napa County specimens. In those specimens, terga 4 and 7 have small, circular, median pale spots and the median tergal spot on segment 5 is similar in shape to the lateral spots In our study of Glenn County specimens the median spot on tergum 4 is absent and the median spots on terga 5-6 are similar in size and shape ( Fig. 16 View Figs ).
Distribution. The holotype specimen of S. thyra is reported to be from “ Nevada ” ( Needham & Smith 1916) and all other known specimens are from California, with most records coming from the Coast Range north of San Francisco. The northernmost record is from Willow Creek in Humboldt County and the southernmost from Uvas Canyon in Santa Clara County. The species is also known from the Sierra Nevada in El Dorado and Placer counties and it co-occurs with S. quadrispinula in the Willow Creek drainage of Humboldt County. However, S. thyra was collected on the main stem Willow Creek while S. quadrispinula occurred in its smaller, high gradient tributaries.
