Aristotelia adceanotha
Keifer, 1935
Aristotelia adceanotha is a small in the Gelechiidae, described by Keifer in 1935. It is native to western North America, with confirmed records from California and Washington. The has a wingspan of 11–12 mm and exhibits distinctive wing patterning with orange-roseate, dark fuscous brown, and white markings. Larvae are specialized feeders on Ceanothus cuneatus, a native shrub in the buckthorn family.

Identification
The combination of small size (11–12 mm wingspan), orange-roseate wing markings contrasting with dark fuscous brown and white fasciae, and the specific pattern of the central fascia with its dark wedge distinguishes this from other Aristotelia. The orange-roseate tornal spot interrupted by a black spot is a key diagnostic feature. Larval association with Ceanothus cuneatus provides additional identification support where plant is known.
