35.0191 Anarsia innoxiella (Maple Snout)
ws: 13-15mm; Jun-Aug?; Acer spp; Status uncertain due to past confusion with A.lineatella but probably well-established in SE England
Anarsia innoxiella §1 female
ID: See Anarsia. Very similar to A.lineatella. Anarsia innoxiella is characterised by its whitish grey and blackish grey forewings, which bear black longitudinal streaks, with the streak in the middle of the wing being especially prominent. There is some variation from light, variegated specimens to darker moths approaching A.lineatella in appearance.
Male genitalia: Separable on 3 features, A.innoxiella given first:
1) sub-apical lobe of the right valva: subtriangular (vs flatly rounded (less protruding)); 2) uncus: conic, triangular (vs slightly more slender);
3) tegumen: moderately broad with weakly sinuous lateral margins (vs broader with distinctly sinuous margins)
Female genitalia: ridges on the ventral surface of S8 are distinct in A.lineatella, but absent or very weak in A.innoxiella.
