Adult habitus. Male forewing length 6.0- 6.5 mm (n = 16), female 6.5-7.0 mm (n = 8). General body color dark brown, head brown on occiput and frons, but with a pale transverse band extending between compound eyes behind ocelli. Pronotum mostly pale brown, but with sutures dark brown, and with a large brown rugose area on either side of median suture ( Fig. 43 View Figs ). Wings brown with conspicuous pale humeral and stigmatic markings, but subapical transverse pale band absent ( Fig. 1 View Figs ). Tibiae almost entirely dark brown and without bands.

Male genitalia (n = 35). Typical of the genus but paraprocts long and slender with fin poorly developed and mostly sclerotized ( Figs. 41 View Figs , 44 View Figs , 46- 51 View Figs ). Paraproct body extending from base to fin apex 425-475 μm in length; greatest paraproct height across fin apex 94-125 μm. The apical digit on the paraprocts ranges from 138-154 μm in length.

Female subgenital plate (n = 2). Median lobe small, parabolic and poorly sclerotized. Large, heavily sclerotized lateral lobes triangular and broadly joined to posterolateral area of sternum 8 forming a continuous sclerotized margin. Median field of plate unsclerotized along a longitudinal stripe. Sternum 9 unsclerotized in a small area posterior to projecting subgenital plate ( Fig. 45 View Figs ).

Egg. Unknown.

Larva. Described by Ricker (1943) and Stewart & Stark (1988, 2002).

Diagnosis. This species lacks the pale wing bands found in most M. zonata   and males have longer and narrower paraprocts than other Moselia   . All specimens examined from Oregon (except Curry, Josephine and most of Jackson counties) and Washington represent this species ( Fig. 52 View Fig ). See additional discussion above. Females of the two species overlap in subgenital plate structure and cannot be reliably distinguished without the pale wing band character.
