Sagephora phortegella is a species of moth in the family Tineidae.[1] It was described by Edward Meyrick in 1888.[2] This species is endemic to New Zealand.[3]
The wingspan is 8–13 mm. The forewings are ochreous-white, the dorsal half suffusedly streaked with whitish-ochreous. There is a thick, gradually-dilated, blackish streak along the costa from base to three-fourths, the apex pointed, the lower margin with a slight projection before the middle. There is sometimes an irregular blackish line below the middle from near the base parallel to the inner and hind-margins to the apex, and a similar almost marginal line along the inner margin to the anal angle, then as a hindmarginal streak to the apex, where it is confluent with the first. Sometimes, there is a defined narrow blackish streak along the inner margin, and a moderate blackish hindmarginal fascia attenuated at the extremities. The hindwings are grey or whitish-grey, rarely rather dark grey.[4]
