Ectoedemia coscoja Van Nieukerken, A. & Z. Laštuvka, 2010
Ectoedemia coscoja
Diagnostic description:Forewing with three white spots as in E. quinquella and E. algeriensis, but separated from both by pale frontal tuft, which is black in the other two. The thorax is completely white as in algeriensis, the spots are almost touching the wing margins, whereas the distal spot in quinquella is usually separate. The male genitalia are very similar to those of algeriensis, but differ by the shorter valvae with a more pointed apex. The female genitalia have very characteristic terminalia with very large setose anal papillae with many setae.
Morphology:Male. Forewing length 2.0–2.2 mm, wingspan 4.3–5.1 mm. Head: frontal tuft yellowish ochreous to ferruginous, collar paler; scape white; antenna brown, with 32–35 segments. Thorax completely dull white. Forewing dark brown, with indistinct pale basal streak and three distinct white spots, one at 1/3 near costa, usually separated from costa by some brown scales, one at dorsal margin in middle and the third at 2/3 near costa, also often separate; cilia-line distinct; cilia silvery white; underside light brown-grey. Hindwing and cilia dark grey; an short ochreous hairpencil; underside ochreous grey. Abdomen grey, with white anal tufts.
Female. Forewing length 1.8–2.3 mm, wingspan 4.4–5.0 mm; antenna with 26–29 segments. Hairpencil absent, further as male.
Male genitalia. Capsule 235–260 μm long. Vinculum very slightly concave anteriorly. Tegumen broadly round-shaped, with several short setae. Gnathos with central element divided, distal part short and tongue-shaped, basal part widened, with serrate margin. Valva length 190–200 μm, inner margin slightly concave to straight, tip acute and curved inwards, distal process with dense short setae on dorsal surface; sublateral processes about ½ length of transverse bar of transtilla. Aedeagus ca 240–265 μm long, pair of ventral carinae pointed.
Female genitalia. Female terminalia very broad and rounded. T8/T7 with two large groups of ca 25–45 long setae along border between segments. Papillae anales broad, appearing as hairy pads, each with more than 100 densely placed short setae. Apophyses anteriores extremely thick in their basal half, forming a keel, which is separated from anal papillae by a distinct groove; thin distally; apophyses posteriores thin. Vestibulum with vaginal sclerite, a prominent dorsal spiculate pouch, and a group of densely packed pectinations near entrance of ductus spermathecae. Corpus bursae 495–695 μm without pectinations; signa dissimilar, longest 320–415 μm (3), shortest 310–370 μm, 3.3–4.3× as long as wide (3). Ductus spermathecae with 2 convolutions.Associations:Hostplant. Quercus coccifera L.
Leafmines. Egg deposited on leaf upperside. Mine a sinuate or contorted gallery, often following veins, slightly and continuously enlarging in its second part, filled with brown to black frass. Not separable from other gallery mines that occur sympatrically: E. haraldi and ilicis.
Larva. Whitish, no chain of ventral plates.Distribution:Spain: Catalunya, Aragon, Andalusia, most records not far from the coast.
Life cycle:Life history. Larvae collected in January and February. Probably univoltine, adults on wings in June and July.

Ectoedemia coscoja is a moth of the Nepticulidae family. It is endemic to Spain (Catalunya, Aragon, Andalusia).
The wingspan is 4.3-5.1 mm. Adults are on wing from June to July. There is probably one generation per year.
The larvae feed on Quercus coccifera. They mine the leaves of their host plant. The mine consists of a sinuous or contorted, gradually widening gallery, often following a vein for some distance, filled with brown or black frass. Pupation takes place outside of the mine.
