Male diagnosis. Inferior appendages of E. simulata and E. maculosa each have 2 stout spines arising from the mesobasal area, with 1–4 smaller black stout spines lateral of these 2 basal spines. The inferior appendages of E. conspersa each have a black, stout spine (Figs. 10a, 11b); the inferior appendages of E. bilera are without spines (Figs. 1a, 1b). Ecclisomyia simulata has the distal area of the fused parameres of the phallus with a deep U- to Vshaped notch (Figs. 30b, 31b); that of E. maculosa has a shallow U- to V-shaped notch (Figs. 22b, 23b). Inferior appendages of E. simulata are longitudinally short, versus long in E. maculosa.
Male description. See Banks (1920); Ross (1950). A supplementary description follows: Length 11–14 mm (N = 15). Head, thorax, legs brown. Wings uniformly brown; hyaline; patterned with whitish spots. Head with 3 ocelli, lateral ocelli closer to eyes than to midline. Antennae each with about 52 segments; except for segments 1 (scape) and 2 each segment with 4–7 stout black to translucent spines positioned midway; spines sometimes closer to distal area of antennal segment; dorsal surfaces clothed with numerous fine black setae. Tergum VIII brown with numerous long setae (Figs. 30a, 31c); sternum VIII brown, with numerous short setae (Figs. 30a, 30b). Pleura well developed, membranous. Superior appendages broader at anterior base, narrowing distally, rounded apically, bearing hair-like setae (Figs. 30a, 30b; 31a, 31b). Tergum IX nearly semicircular in lateral view longest mesolaterally, longitudinally short dorsally and ventrally; dorsal, ventral, and anterior margins heavily sclerotized (Figs 30a, 31a); left and right lateral portions connected dorsally and ventrally with transverse sclerotized bridges (straps) (Figs. 30b, 30c, 31c). Tergum X elongate, extending caudad, with many small spicules (Fig. 30a). Intermediate appendage ventral of tergum X sclerotized; distal margin with several elongate setae (Figs. 30a, 31a). Apices of parameres fused, with deep U-shaped notch apically forming 2 prong-like caudal extensions (Figs. 30b, 30c; 31b, 31c). Phallus with broad phallocrypt; narrowing posteriorly, curving dorsad. Inferior appendages triangular in lateral aspect (Fig. 30a); long hair-like setae on lateral and distal dorsal and ventral surfaces; each with 2 large stout black to reddish-brown spines arising from base and extending caudad (Figs. 30b, 31b). Lateral of these two black spines 2–4 shorter, dark brown to black spines (Figs. 30b, 31b).
Female diagnosis. The distal margin of tergum X has a U-shaped incision extending about 3/4 the length of the segment (Figs 32a, 32b); the distal margin of tergum X of E. maculosa has a V-shaped incision extending about 1/2–3/4 the length of the segment (Figs. 24b, 25b). The external part of gonopod VIII is large in both species, but in E. simulata it is longer than wide (Figs. 32a, 32b) whereas in E. maculosa it is nearly as wide as long (Figs. 24c, 25b, 25c) and in E. bilera it is short and narrow (Figs. 3b, 4a). In all females of E. simulata examined, the caudal margin of the external part of gonopod VIII is concave. The external part of gonopod IX has a mesal V-shaped incision, whereas in E. bilera it is concave in ventral aspect. The external gonopod of segment IX sclerotized, wide, not as deeply incised as in E. maculosa, only extending posterad 1 X its width (Figs. 32a, 32b); in E. maculosa the external gonopod of segment IX is narrow caudal margin with deep V-shaped declivity, extending posterad about 2 X its width beyond caudal margin of the external part of segment VIII (Figs. 24c, 25b, 25b). The spermathecal sclerite is quadrate in E. simulata (Figs. 32a, 32b) and not as long as in E. conspersa (Fig. 13a) nor as rounded as in E. bilera (Fig. 3b).
Female description. Length 11–14 mm (N = 15). Tergum X fused with tergum IX; viewed from dorsal aspect incised into 2 lobes, incision about 1/2–to 3/4 length of tergum. External gonopod of segment VIII large; caudal margin concave; lateral margins straight (Figs. 32a, 32b). External gonopod of segment IX sclerotized, divided mesally with V-shaped incision (Figs. 32a, 32b); fused anteriorly, forming dorsal surface of vaginal opening; extending beyond vaginal opening and 1 X its width posterad of external gonopod of segment VIII; lobes flared laterally; flanged in lateral aspect. Spermathecal sclerite compact, extending anterad about 1/2 length of abdominal segment VIII; about as wide as long, but sometimes slightly wider than long (Figs. 32a, 32b).
Pupal diagnosis. The E. simulata pupa may be separated from pupae of the other three Nearctic Ecclisomyia species by the presence of dorsal gills on abdominal segment IIa, absent in the others. The E. s imulata pupa may also be separated from the pupa of E. conspersa by the absence of lateral line gills that are present on abdominal segments IIp–IVa of the E. conspersa pupa (Fig. 42). Each apical process of E. simulata has 2 stout, long, black setae at the apex (Figs. 33a, 35a), whereas those of E. conspersa each have 3 stout, long, black setae (Figs. 15a, 17a).

Profemora each also with single short black spine on ventral surface near distal margin. Mesotarsal segments 1–4 each with pair of lateral fringes of long, fine, brownblackish to reddish to opaque fine silk-like hairs, directed posterad.
Abdomen: Dorsal abdominal segments light brown to reddish brown. Lateral fringe of long fine black hairs on each side directed dorsad; originating from posterior margin of abdominal segment V; line of fringe arching ventrad, extending to posterior margin of abdominal segment VIII. Dorsal and ventral abdominal gills each singlefilament; present dorsoposteriorly and ventroposteriorly on segments II–VII; present dorsoanteriorly on abdominal segments II–VII; present ventroanteriorly on abdominal segments III–VII (Fig. 42).

Case compact, without open interstitial spaces; constructed of large pebbles and small grains of sand (Fig. 43d). Both ends of case rounded, less compact, with small open areas. Cases attached to rocks such that case orientation permitting flow of water through case.
Larval diagnosis. The E. simulata larva has single-filament gills dorsoanteriorly on dorsal abdominal segment II, whereas E. conspersa, E. bilera, and E. maculosa larvae typically lack these gills. The lack of lateral-line gills will also separate the E. simulata larva from the E. conspersa larva. The E. simulata larva has dorsoanterior and ventroanterior gills on dorsal abdominal segment VII, lacking in the E. maculosa larva (Fig. 42). Some mature larvae (11 mm in length) lack dorsoanterior gills on abdominal segment II, however the gill arrangement for abdominal segment VII fits the pattern for the E. simulata larva. The E. simulata larva has a prosternal sclerite lacking in E. maculosa.

Distribution. Ecclisomyia simulata has been recorded in the Cascade Mountain range of Oregon and Washington (Ross 1950) and the Sierra-Nevadas of California and Nevada (Banks 1920; Ross 1950; Denning 1951; Givens 2014). I have collected and examined E. simulata from California, Idaho, Nevada, Oregon, and Washington.
Bionomics. Ecclisomyia simulata is a higher altitude species, with altitudes ranging from 1223–2225 m. Emergence begins in late April extending into mid-August. The creeks and streams in which larvae occur tend to be narrow, 0.6–3.05 m, however E. simulata larvae may also be found in larger and deeper streams, up to 4.6 m wide and 0.6 m deep. Typically, stream depth ranges from 5.08–30.5 cm. These streams are generally rapid, fast flowing, frequently turbulent, with cobble, gravel, and sand substrate. In common with the other Nearctic Ecclisomyia species, much instream woody debris often occurs. Ecclisomyia simulata has been reported sympatric with E. bilera and E. conspersa (Givens 2014).
