Arctopsyche oregonensis Ling 1938, 65, male. Ross (1944, 293, synonym). Male. Description: See Ross (1938, 119, pl. 12 figs. 5, 5 A); Givens & Smith (1980, 4, 18 figs. 9 a, b); Nimmo (1987, 14 �� 15, 19 figs. 25��28). Female. Diagnosis. The female of P. a l m o t a is distinguished from P. extensa, P. turbinata, and P. spinat a by the shape of tergite IX. In both P. extensa and P. turbinata, the lateral regions of tergite IX are each divided by a vertical suture into anterior and posterior sections (Figs. 5 a, 8 a). This suture is absent in P. a l m ot a (Fig. 1 a). Unlike P. spinata, tergite IX of P. a l m ot a curves outward posteriorly (Fig. 1 a), whereas the dorsal posterior margin of P. spinata curves inward anteriorly (Fig. 6 a). The narrow dorsal cap of P. al m o t a separates the P. almota female from that of P. e l s i s, which has a broad dorsal cap and a very narrow stem extending into the pleurosternum (Fig. 3 a). The shape of the internal sclerotized structure (ist) within the fused sterna IX and X, best seen in cleared specimens, is also diagnostic for P. almota and P. elsis females (Fig. 1 a, 1 b, 3 a, 3 b). Description. See Ross (1938, 119); Givens & Smith (1980, 4, 19 figs. 12 a��c); Nimmo (1987, 14, 19 figs. 29, 30). Pupa. Diagnosis. The P. a l m ot a pupa is distinguished from the pupae of P. elsis and P. turbinata by the number of hooks on IIIp and Vp (Fig. 28) and the form of the apical processes (Figs. 2 a, b). In P. elsis the apical processes curvature is greater than 90 �� to the longitudinal axis and have long tubular yellow setae (Figs. 4 a, 4 b). The apical processes of P. a l m o t a more closely resemble the apical processes of P. turbinata. However, the bifid apices of P. al m o t a processes in ventral view are acute (Figs. 2 b, 2 c), whereas the apices of P. turbinata processes are less acute (Fig. 9 b). The form of the caudoventral and anal areas of the apical processes of the male pupa will also separate these 2 species (Figs. 2 b, 9 b). The anal area of the female pupa is different in appearance (fig. 2 c). The P. spinata pupa has rounded, blunt, and unequal apices and lacks spines on the lateral surface of the apical processes (Figs. 7 a, 7 b), unlike P. al mota and P. turbinata. Parapsyche almota usually has 8��14 hooks on each hook plate IIIp, whereas P. spinata usually has 6��9 hooks on each IIIp (Figs. 23, 25, 28). Parapsyche almota lacks a pair of hook plates on IVp, whereas P. turbinata has a pair of small sclerotized plates, without hooks, at position IVp (Figs. 23, 26) as well as a greater number of hooks on hook plate IIIp and Vp (Fig. 28). Description. See Smith (1968, 105). A supplementary description follows: Length 9��16 mm, N= 10 (7 males, 3 females). Hook plates present anteriorly on abdominal segments III��VII, and posteriorly on segments III and V. Each hook plate IIIa with 6 �� 13 hooks; IIIp with 8 �� 14; IVa with 1 �� 3; Va with 1 �� 3; Vp with 9 �� 13; VIa with 2 �� 6; and VIIa with 3 �� 5. Hook plates Vp and IIIp oval (Fig. 23). Pupal apical processes bifid, apices acute, V-shaped, recurved anterodorsad 70��80 o to axis of body (Figs. 2 a��c); caudal inner surfaces concave, clothed with numerous spines. Spines present over much of lateral surfaces of apical processes, greater in number dorsally on posterior lateral surfaces. Bases of apical processes each with tuft of reddish-tan ls setae (Figs. 2 a��c). Pupal Case. See Givens & Smith (1980, 5, 22 fig. 30) and Fig. 29. Larval Retreat. The retreat is generally constructed of vascular plant detritus or other plant material. A typical capture net is constructed with square mesh (Wallace 1975). The larval retreat has 2 separate, more or less parallel chambers, with water flowing through both the larger anterolateral chamber with the capture net, and the smaller posterolateral chamber with the larva; the anterior opening for the larger chamber is in front of the capture net and the anterior opening for the smaller chamber is near the capture net. In the creek flowing out of Lake Grace, 2.57 km south east of Shingletown, Shasta Co., CA, sampled in 2011, unusual retreats were constructed primarily of algal filaments, in which the capture net was constructed of silk mesh attached to a circular net frame of algal strands. The retreats were less structurally defined and less rigid than those constructed of vascular plant detritus. Larva. Diagnosis. The shape of the ventral apotome is diagnostic; the posterior marginal area is flanged, with the width of the mesal area narrower than the width of the posterior margin (Fig. 14). The ventral apotome in early instars is similar; however the ventral apotome is less quadrate, often 5��6 �� as long as wide mesally, somewhat resembling the ventral apotome of P. spinata. The ventral apotome of the first instar is very narrow, similar to that of P. e l s i s. The ventral apotome of P. turbinata and P. spinata has parallel margins without mesal indentations and posteriorly does not flare laterally. The absence of fluted scale hair (f-sh) setae on the dorsal surface of the abdomen will separate P. almota from P. turbinata. The P. a l m ot a larva, like that of P. e l s i s, is without gills on abdominal sternum VIII; gills are present on abdominal segment VIII in the other 3 species of western Parapsyche. Tergum IX has lateral areas lightly to heavily sclerotized, with 1 black primary seta and appressed hl setae as occurs in P. extensa. Lateral areas of tergum IX in P. s pi na t a are lightly to heavily sclerotized, each with a single black primary seta, frequently with 1 sl seta and appressed hl setae; in P. turbinata the lateral dorsal areas of abdominal segment IX are without evident sclerotization and with black primary setae and appressed hl setae scattered over the dorsal surface. Uniquely, the anal tuft of each proleg of P. a l m o t a consists of 15��35 (average of 22) thin setae; Each anal tuft of the other western North America Parapsyche have only 3��14 (average of 8) stout setae. Description. Smith (1968, 105). A supplementary description follows: Length (fourth and fifth instars) 14��22 mm (N= 25).

Abdominal sternum VIII without gills. Sternum VII with pair of short black primary setae positioned submesally. Anal Proleg: Caudal lobe yellow, with dark appressed hl setae ventrally; dorsal surface glabrous. Basal tufts each with 15��35 reddish-black, thin ls setae. Numerous dark (tan to reddish) sl setae on lateral surface of each proleg, intermixed with numerous short appressed hl and dark, long ls setae. Frequently with 2��5 anal gills. Mesal surfaces of prolegs with many long, thin, black ls setae. Distribution. Smith (1968), Givens (1976), Givens & Smith (1980), and Nimmo (1987). Parapsyche almota is sympatric with P. el s i s, A. grandis (Banks 1900), and A. californica Ling 1938. Where P. a l m ot a occurs in association with P. e l s i s, A. grandis, and A. californica, the streams are often 2��9 m wide with a depth of 0.6��1.2 m. Flow is usually rapid and often turbulent. In only 1 stream collected by the author, P. almot a was sympatric with P. elsis, A. grandis, and A. californica. Bionomics: Larvae of P. a l m o t a occur primarily in a cobble, sand, gravel substratum, with a matrix of small to medium rubble and woody snags.
