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 (Figs 74, 77, 78). 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 (Figs 75, 87, 89). 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.

Distribution. Spain: Catalunya, Aragon, Andalusia, most records not far from the coast.
