Ectoedemia (Ectoedemia) alnifoliae

Figs 73, 81, 94, 99, 103, 107, 113, 114, 118
Diagnosis
.
Externally
Ectoedemia alnifoliae
is similar to
E. rufifrontella
, but is overall more uniform, has fewer pale scales and is more distinctly yellow. Th e male genitalia most resemble those of the
E. albifasciella
complex, but the valva is more “bulging” distally; the valva reminds of
E. haraldi
, but that has an overall concave inner margin and a divided gnathos. Th e female genitalia differ from those of
E. rufifrontella
by having just two convolutions in the ductus spermathecae against ca
13–14 in
rufifrontella
, female genitalia hardly separable from those of
haraldi
.
Redescription
.
Male (Figs 73, 113). Forewing length 2.0–3.0 mm, wingspan 4.5– 6.7 mm. Head: frontal tuft orange, collar ochreous; scape white, often with some darker scales; antenna brown, with 36–44 segments. Th orax and forewing unicolorous, covered with coarse brown scales, less dense in tornus, and few pale scales; cilia-line distinct; terminal cilia silvery white; underside brownish grey. Hindwing and cilia dark grey, hindwing with costal bristles, no hairpencil. Abdomen fuscous, anal tufts ochreous.
Female (Fig. 114). Forewing length 2.2–3.0 mm, wingspan 4.9–6.6 mm. Antennae with 27–31 segments.
Male genitalia (Figs 81, 103). Capsule length
230–310 µm
. Vinculum slightly concave anteriorly. Tegumen distinctly produced in a hemispheric pseuduncus, with simple long setae. Gnathos with central element short, with blunt, truncate tip, not separated in two parts; lateral processes long. Valva length
175–220 µm
, broad with distal process pointed and strongly curved inwards, outer margin slightly bulged, inner margin in middle distinctly convex, with long setae on dorsal surface and on caudal part, sublateral processes more than one third transtilla length. Aedeagus
250–300 µm
long, with distinct cathrema, numerous very small cornuti in vesica, carinae simple, elongate.
Female genitalia (Figs 94, 99, 107). T7 without row of setae. T8 with two lateral groups of scales and a few setae; posterior margin slightly indented, with rounded corners. Anal papillae with ca 15–20 setae. Vestibulum with vaginal sclerite, a prominent spiculate pouch and a group of densely packed pectinations near entrance of ductus
