Yakima Co., American River, Pleasant Valley Campground, 10 June 2001, D. Strenge, 2♀ (CSUC) . Egg. Outline oval. Length ca. 390-410 μm, equatorial width ca. 263-267 μm (Fig. 1). Collar short, wide with sides elaborately dissected; base surrounded by a low, irregularly-multitoothed rim. Anchor mushroom shaped and abundantly covered with globular bodies (Figs. 1, 3). Surface covered with widely-spaced, irregular striae along longitudinal axis; striae composed of linear tubercles ca. 20-25 μm long and ca. 5-10 μm thick (Figs. 2-6). Surface between striae relatively smooth, but bearing a few, scattered globular bodies. Micropyles subequatorial in position, located on modified strial elements (Fig. 2); orifices smaller than width of strial tubercles.</p><p>Comments. The images (Fig. 13 in Stark &amp; Surdick 1987; Fig. 1.9 in Stark et al. 1998a) prepared from eggs taken from a Muir Creek, Oregon female collected in May 1982 are consistent with the images presented herein from Montana and Oregon, and also consistent with eggs from California and Washington specimens examined from the sites listed above. One female from Humboldt Co., California had eggs typical of this species, although eggs from other specimens collected in that area were typical of K. takhoma . No eggs were present in specimens examined from Alaska, but one Canadian female from Summit Creek, British Columbia contained eggs which were typical of K. perdita . Scanning electron micrographs (Figs. 7-8) are provided to show the relatively straight anterodorsal margin of the K. perdita male epiproct. In this species and K. siskiyou, described below, the smooth, sclerotized anterodorsal margin is completely black, whereas this structure is usually bicolored with a brown band appearing adjacent to the marginal black pigmented area in K. takhoma . The anterodorsal margin of the epiproct of K. perdita is also straighter than either of the other species.</p><p>Distribution. The species is reported from Canada: Alberta and British Columbia, and the United States: Alaska, California, Idaho, Montana, Nevada, Oregon and Washington (Baumann et al. 1977; Kondratieff &amp; Lechleitner 2002; Stark &amp; Surdick 1987; Stewart &amp; Oswood 2006; Stewart &amp; Ricker 1997; Stewart &amp; Stark 2002).</p></div>	https://treatment.plazi.org/id/039787E2FFCAFFC8ED9127132D3BF91C	Public Domain	No known copyright restrictions apply.

Basal cercal segments ca. 2-2.5 X long as wide. Vesicle body almost circular but with moderately wide base forming a short, stalk-like structure (Fig. 17). Aedeagus broad and membranous except for a pair of curved, dark brown lateral bands and a ventromedian pale sclerite (Fig. 18); surface of lateral bands bear fine, short, densely packed setae; distal margins foot-shaped. Aedeagal apex consists of three membranous lobes, median lobe finely divided by a suture-like line along most of its length.</p><p>Female. Forewing length 17-18 mm. Lateral margins of subgenital plate slightly concave beyond midlength, apex notched; apex extends over base of sternum 9 (Fig. 19).</p><p>Egg. Outline oval. Length ca. 380-400 μm, equatorial width ca. 230-240 μm (Figs. 9-10). Collar short, ca. 22-30 μm, wide ca. 70-80 μm (Fig. 11), elaborately dissected, and surrounded by three irregular rows of meshes and a conspicuous outer ridge forming a ring ca. 104 μm in diameter (Figs. 11-12). Anchor well developed, cushion shaped and covered with small globular bodies (Fig. 10). Chorion bearing multiple rows of longitudinal striae composed of closely grouped, irregularly shaped tubercles ca. 2-3 μm wide; interstrial areas bear scattered tubercles similar to those which comprise striae (Figs. 11, 13). Micropyles subequatorial in position and often associated with striae (Fig. 14); orifices slightly larger in diameter than bead-like components of striae.</p><p>Larva. Unknown.</p><p>Etymology. The species name, used as a noun in apposition, is based on the type locality in the Siskiyou Mountains of southern Oregon. The proposed common name, Wagner Gap Sallfly, is based on the access road into the sites where most of the known specimens were collected. Common names for K. perdita (Longhead Sallfly) and K. takhoma (Slenderhead Sallfly) were previously proposed by Stark et al. (1998b; 2012).</p><p>Diagnosis. Although some overlap in subgenital plate shape occurs, females of K. siskiyou are usually distinguished from K. takhoma by a shorter subgenital plate, and by the egg structure which bears a collar and longitudinal striations formed from bead-like tubercles (Figs. 11, 13). The new species and K. perdita completely overlap in subgenital plate structure and in head pattern, but the eggs differ in the form of the chorionic tubercles. In K. perdita these structures are thick and long (Figs. 5-6), whereas in the new species they are formed as longitudinal clusters of beadlike structures (Figs. 11, 13). The only known male specimen of this species appears intermediate between K. perdita and K. takhoma . The basal cercal segments and, general head coloration and pigment pattern of the dorsal margin of the epiproct are similar to those of K. perdita, whereas the vesicle shape and dorsal epiproct margin are more similar to K. takhoma . Males of the three Nearctic species have similar aedeagal structure but when a larger sample is available the shape and size of the lateral sclerites may offer another useful character. We offer a preliminary key below to assist in distinguishing these three species.</p></div>	https://treatment.plazi.org/id/039787E2FFCFFFCBEE8C20E82A3BFBA9	Public Domain	No known copyright restrictions apply.
