Ancylis unguicella

Gilligan, Todd, Huemer, Peter & Wiesmair, Benjamin, 2016, Different continents, same species? Resolving the taxonomy of some Holarctic Ancylis Hübner (Lepidoptera: Tortricidae), Zootaxa 4178 (3), pp. 347-370 : 349-351

Ancylis unguicella group

The taxa treated here can be divided into two groups based primarily on the structure of the male genitalia. The first group, the A. unguicella group, contains A. unguicella , A. pacificana , A. uncella , A. goodelliana , and A. oregonensis . Of these, A. unguicella and A. uncella have a Holarctic distribution, the latter as a result of being synonymized here with A. carbonana .

Species in this group can be identified using a combination of wing pattern and genitalia. Male genitalia exhibit some intraspecific variation but are generally more diagnostic than in the A. geminana group. Female genitalia are relatively uniform but have a few species-specific characters. Shared characters include:

Male genitalia. Uncus bifid, well developed in all species except A. oregonensis . Socii large, membranous, setose pads. Valva with costal margin concave; saccular angle weakly to moderately developed; neck width relatively uniform; cucullus densely setose, outer margin convex, apex acute to broadly rounded. Caulis long; phallus 0.5 to equal length of valva; vesica with numerous deciduous lanceolate cornuti.

Female genitalia. Papillae anales moderately setose. Apophyses posteriores and apophyses anteriores approximately the same length. Lamella postvaginalis membranous, undefined; lamella antevaginalis sclerotized, projecting ventrally above ostium, often with slight median indentation, forming a funnel-shaped antrum that is sclerotized 0.4–0.6 length of ductus bursae (except in A. oregonensis ). Colliculum present as two lateral sclerites of varying length continuous with anterior sclerotization of antrum. Ductus seminalis arising from near junction of ductus and corpus bursae. Corpus bursae large, oval; two blade- or horn-shaped signa present.
