Ecclisomyia bilera Denning 1951 View in CoL , 161, figs. 5a, 5b, 5c, male, female. Holotype male: Shasta Co., California, Lassen National Park, King's Creek Meadows, July 23, 1950, (C.P. Alexander) (CASC); Allotype female: same data as for holotype (CASC); Erman & Erman (1990, 12, 13, 15, 24, distribution, biology); Givens (2014, 159, 170, distribution).
Male diagnosis. Tergum X is foliaceous, appearing long and rectangular and apically truncate in dorsal and ventral views, curled evenly ventrad in lateral view ( Figs. 1a, 1b, 1c View FIGURES 1 ); tergum X is acute or blunt in dorsal or ventral views in the other species and thicker and less curled in lateral view. The distal ends of the parameres of the phallus (ph) are angled dorsad ( Figs. 1a View FIGURES 1 , 2a View FIGURES 2 ); parameres are nearly or entirely straight in the other species. The inferior appendages of E. bilera lack spines, whereas E. conspersa has a stout, basal spine arising from each inferior appendage ( Figs. 10b View FIGURES 10 , 11b View FIGURES11 ); E. maculosa and E. simulata have 2 black stout spines arising from the mesobasal area of each inferior appendage, with 1–4 smaller black stout spines lateral of these 2 basal spines ( Figs. 22b View FIGURES22 , 23b View FIGURES23 , 30b View FIGURES 30 , 31b View FIGURES 31 ).
Male description. See Denning (1951, 161, figs. 5a, 5b). Supplementary description follows: Length 8–11 mm (N = 16). Head, thoracic nota dark brown to dark fuscous.

The distal margin of tergum X ( Figs. 3c View FIGURES 3 , 4c View FIGURES 4 ) with V-shaped incision extending about 1/2–3/ 4 the length of the segment, unlike the shallow mesal notch in segment X of E. conspersa female ( Figs. 12 View FIGURES 12 , 13a View FIGURES13 ). The external part of gonopod VIII short as in the E. conspersa female, but the distal (posterior) margin with a Vshaped indentation; contrasting with that of E. conspersa with a concave posterior margin that is sometimes convex; the external part of gonopod VIII is large in E. maculosa and E. simulata ( Figs. 24c View FIGURES24 , 32a View FIGURES 32 ). The posterior margin of the external part of gonopod IX in E. bilera broadly concave; in E. conspersa with a U-shaped mesal indentation. The spermathecal sclerite round and broader posteriorly than anteriorly, whereas in E. conspersa , the spermathecal sclerite is narrower posteriorly than anteriorly ( Figs. 12 View FIGURES 12 , 13a View FIGURES13 ) or subquadrate in E. maculosa and E. simulata .

External part of fused gonopods IX short, concave dorsally, convex ventrally; serving as dorsal sheath for vaginal opening and extending beyond it; obscure, not heavily sclerotized; distal margin with broad U-shaped mesal indentation. Spermathecal sclerite rounded anteriorly, lateral margins heavily sclerotized, ribbed.
Pupal diagnosis. The Ecclisomyia bilera pupa may be separated from the pupa of E. conspersa by the absence of lateral line gills; with gills present on abdominal segments IIp–IVa of E. conspersa ; from E. simulata by the absence of subdorsal gills on the anterior margins of abdominal segment II ( Fig. 42 View FIGURE 42 ); with gills present subdorsally on IIa of E. simulata ( Fig. 42 View FIGURE 42 ). The Ecclisomyia bilera pupa has gills (dorsally and subventrally on VIIa; the E. maculosa pupa lacks such gills ( Fig. 42 View FIGURE 42 ). The apical processes of E. bilera , E. maculosa , and E. simulata each have 2 stout, long, black apical setae ( Figs. 5a View FIGURES 5 , 6a View FIGURES 6 , 26a View FIGURES 26 , 27a View FIGURES 27 , 28a, 33a View FIGURES 33 , 34a View FIGURES 34 , 35a), whereas those of E. conspersa each have 3 long, black stout setae ( Figs. 15a View FIGURES 15 , 16a, 17a, 18a).

Pupal case rounded; slightly wider anteriorly, but generally uniform in diameter. Pebbles at both ends loosely attached, leaving gaps between pebbles. In one site, cases were not attached to rocks, but lying in pools of a shallow creek without any apparent orientation to water flow; those pupal cases shorter, less streamlined ( Fig. 43 View FIGURES 43 a-2).
Larval diagnosis. Of the four Nearctic species of Ecclisomyia , only the larva of E. bilera lacks mesal stripes on the head and thorax, diagnostic for this species. The posterior area of the frontoclypeus has indistinct muscle scars as occurs in E. simulata . Ecclisomyia conspersa and E. maculosa are without muscle scars on the frontoclypeus or the scars are indistinct. Each metathoracic sclerite sa 1 has 9–15 long black setae, whereas this sclerite on the other three Nearctic Ecclisomyia species each has 4–8 long black setae. The E. bilera larva does not have lateral line gills, whereas the E. conspersa larva has lateral line gills on abdominal segments II–IV ( Fig. 42 View FIGURE 42 ). The larva of E. maculosa , unlike that of E. bilera , lacks anterior dorsal and ventral gills on abdominal segment VII ( Fig. 42 View FIGURE 42 ). The larva of E. simulata , unlike other Nearctic Ecclisomyia species, has anterior gills on the dorsum of abdominal segment II ( Fig. 42 View FIGURE 42 ).

Distribution. Specimens of E. bilera during this study were from Shasta and Tehama counties, California, and Washoe County, Nevada. Ecclisomyia bilera was previously recorded from Shasta and Tehama counties, California ( Givens 2014). This species has also been recorded from Nevada and Sierra counties in California ( Erman & Erman 1990), and Mono County, California ( Maciolek & Tunzi 1968). Ecclisomyia bilera appears to be restricted to the Sierra Nevada Mountains of California and Nevada. Ecclisomyia bilera is sympatric with both E. conspersa and E. simulata ( Givens 2014) .
Bionomics: Ecclisomyia bilera is a high-altitude species, occurring at elevations of 1737–2455 m. Emergence commences in late June, and extends into the middle of August. This species has been collected from larger creeks with widths up to 3.05 m and depths up to 0.91 m, but this species seems to occur primarily in narrow (0.30–1.8 m), shallow (7.6–45.7 cm), rapidly flowing creeks with cobble, gravel, and sand substratum. These streams usually have mixed plant debris, frequently with wood and bark debris.
