Oinophilidae, Opogonidae. ~ Tineidae.

Adults relatively long-bodied; relatively slender-bodied (wingspan more than 15 times the thoracic width) to medium built (wingspan more than 8 and less than 15 times the thoracic width); wings in repose packed with the forewings directed backwards to cover hindwings and abdomen.

Head rough (the crown roughly tufted, in Oinophila). Antennae long; extending to about about 0.8 times the length of the forewing. Antennae of males simple; non-ciliate. The antennal scape without a pecten; not forming an ‘eye cap’. Ocelli present. Chaetosemata absent. Maxillary palps well developed (fairly long); 3–5 segmented (? - ‘several jointed’); folded (filiform). Labial palps well developed; porrect; 3 segmented. Proboscis absent (‘obsolete’).

Wingspan 8–12 mm (Oinophila), or 20–28 mm (in Opogona); 14–16 times the thoracic width. Forewings with their apices conspicuously bent up or down when the insect is at rest (downturned, in Oinophila); narrow; about 4–4.6 times as long as wide. Tornus undetectable. Forewings apically pointed; ground colour predominantly ochreous-fuscous. Hindwings narrow-elongate and very long-fringed; linear to linear-lanceolate; very much narrower than the forewings to quite markedly narrower than the forewings; with a pointed apex. The fringe of the hindwings 5–6 times the width of the membrane. The upper surfaces plain; with neither discal spot nor transverse lines; hindwings with a frenulum.

Neuration of forewings and hindwings dissimilar. Forewings with well developed neuration (Opogona), or with greatly reduced neuration (veins 3, 4 and 11 lacking in Oinophila); 9 veined (Oinophila), or 14 veined (Opogona); with 1 anal vein, or with 2 anal veins (in Opogona?). The anal veins of the forewings representing 1b only, or comprising 1b and 1c. Forewings exhibiting a tubular vein 1c (in Opogona?), or lacking a tubular vein 1c. Vein 1b of the forewings simple. Forewings with a discal cell. Discal cell of the forewings without a tubular media (M) vein. Hindwings with greatly reduced neuration; 6–7 veined; seemingly lacking anal veins; without a discal cell.

Fore-legs with a tibial epiphysis. Tibiae of middle legs 2-spurred. Posterior tibiae 4-spurred; hairy.

Eggs, larvae and pupae. Larval prolegs 10. Larvae more or less concealed feeders, or exposed feeders (those of Oinophila v-flava forming silken galleries, in fungi and refuse).

Empty pupae protruded from place of concealment.

British representation. Genera 2 (Oinophila, Opogona); 3 species (both Opogona species being adventive).

Classification. Microlepidoptera. Suborder Ditrysia. Superfamily Tineoidea.
