Species Ancylis diminuatana - Hodges#3379

3379

Ancylis diminuatana Kearfott, 1905 (1), (2)

Ancylis diminutana of authors (not Haworth, 1811)

Ancylis geminana of authors (not Donovan, 1806)

Phylogenetic sequence #620668

Specific epithet for "a specimen of this species labeled 'diminuatana Wlsm.,' but I have not been able to find the name or a description in any of Walsingham's writings." (1)

Ancylis diminuatana Kearfott, 1905 was synonymized with Ancylis diminutana (Haworth, 1811) in Heinrich (1923)(3). Hodges et al. (1983)(4) erroneously listed A. diminuatana as a misspelling of A. diminutana. Both A. diminuatana and A. diminutana were in turn synonymized Ancylis geminana (Donovan, 1806) in Brown (2005)(5). Gilligan et al. (2016) elevated both A. diminutana and A. diminuatana back to full species status. A. diminutana and Ancylis geminana are now considered to be strictly Eurasia species. (2)

Wingspan 13.5-15 mm. (1)

FWL ♂ 4.5–7.5 mm, ♀ 5.5–8 mm. (2)

Adult - Very similar to Ancylis goodelliana. The main difference between A. diminutana and A. goodelliana is how straight or even the border between the dark and light halves of the wing is. A. goodelliana should have a more even lateral line separating the dark and light, while A. diminutana has a very sinuous line.

The above comment was made prior to Gilligan et al. (2016) (2) which also mentions, "The light gray to white costal margin and black streaks along the radius and cubitus of the forewing separate A. goodelliana from other Ancylis treated here." The pale area of the costal margin is usually more extensive than it is for A. diminuatana, usually reaching the apex and the black streaks can be heavy but are usually very light making identification for some (most?) individuals difficult without dissection.
