Type material. Holotype. Ƌ: “ Oregon, Crescent Lake, Klamath Co., 4600‘ 7.VII 1955, JFG Clarke “ ( USNM) . Paratypes (9). United States: 3 Ƌ, 6 ♀ [same data as holotype], slides TMG630, TMG633 ( USNM) .

Diagnosis. Ancylis oregonensis is distinguished from all other species treated here by the discontinuous longitudinal line of the forewing, which is broken or obscured in the middle in most specimens. In individuals where the longitudinal line is nearly continuous (Fig. 25), the costal and dorsal halves of the forewing are not deeply contrasting. The male genitalia are also unique in this species, with the cucullus well-defined, the phallus as long as the valva, and the uncus reduced.

Description. Head, labial palps and thorax light brownish gray. Forewing. FWL Ƌ 6.5–8.7 mm (n=4), ♀ 7.0– 7.8 mm (n=6). Forewing is falcate. The costal half of the wing is a mix of light brownish gray, dark brown, and black. The costa is light grayish brown in the basal half becoming a mix of gray, brown, and dark brown in the apical half with remnants of dark brown costal strigulae in some individuals. The dorsal half of the wing is light brownish gray. The longitudinal line starts at A1+2, extends towards the termen, and is disrupted in the middle onethird of the wing by brownish gray scales of the dorsal half of the wing extending to the cubitus. Beyond the disruption the longitudinal line is usually well defined, continuing from CuA2 straight to the apex. Cilia at the apex dark brown to black with a white postapical strigula. Hindwing pale grayish brown. Male genitalia. Uncus bifid, reduced, ca. 0.5 as tall as wide. Valva with shallow basal excavation extending to neck; saccular angle strongly developed with triangular terminal projection; neck narrowed from sacculus to cucullus, ventral margin semicircular; cucullus well-defined, densely setose, outer margin convex with several rows of short setae, costa weakly convex. Caulis 0.25 as long as phallus; phallus as long as valva, with small triangular tooth at apex; vesica with ca. 45 deciduous cornuti. Female genitalia. Apophyses posteriores 0.75 as long as apophyses anteriores. Lamella postvaginalis membranous, undefined; lamella antevaginalis sclerotized, projecting ventrally above ostium; antrum weakly developed; colliculum two small lateral sclerites. Ductus seminalis arising at junction of ductus and corpus bursae. Corpus bursae large, oval; two horn-shaped signa present.

Molecular data. Unknown.

Distribution. Ancylis oregonensis is known only from the type locality, Crescent Lake, located on the eastern side of the Cascades in Klamath County, Oregon.

Biology. The only collection data are from the type series, and all specimens were collected on the same night in early July. The larval host is unknown.

Etymology. The name signifies that this species has only been recorded from Oregon.
