Eupistidae, Augasmidae.

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 smooth. Antennae of medium length to very long; extending to about 0.7–1.5 times the length of the forewing. Antennae of males simple; non-ciliate. The antennal scape with a pecten (at least, “with a scale-tuft”); not forming an ‘eye cap’. Ocelli absent. Chaetosemata absent (?). Maxillary palps much reduced (minute); 2 segmented. Labial palps porrect to ascending (fairly long, curved); 3 segmented. Proboscis fully developed; scaly towards the base.

Wingspan 8–18(–21) mm; 13–19 times the thoracic width. Forewings narrow; 3.6–9.2 times as long as wide. Tornus weakly defined to undetectable. Forewings apically blunt to pointed; predominantly shining-metallic, or neither shining-metallic nor with shining metallic markings (plain, consistently lacking transverse markings). Hindwings narrow-elongate and very long-fringed; linear-lanceolate to ovate-lanceolate; very much narrower than the forewings to similar in breadth to the forewings; with a pointed apex. The fringe of the hindwings 3–6 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 9 veined, or 10 veined, or 11 veined (lacking veins 5, 8 and sometimes also 4 or 3 and 4); with 2 anal veins. The anal veins of the forewings comprising 1b and 1c. Forewings exhibiting a tubular vein 1c (distally). Vein 1b of the forewings furcate proximally. The transverse vein complete. Discal cell of the forewings without a tubular media (M) vein. Hindwings 7–9 veined; with 1 anal vein, or with 2 anal veins. The anal veins of the hindwings representing 1b only, or comprising 1a and 1b. Hindwings exhibiting vein 1a, or lacking vein 1a; theoretically lacking a tubular vein 1c; with a discal cell to without a discal cell. The transverse vein incomplete to lacking. When cell present, 4 veins arising from the hindwing cell, or 5 veins arising from the hindwing cell (with vein 4 usually absent, sometimes also vein 5). The cell-derived hindwing veins 6+7 proximally joined. Vein 8 of the hindwings when cell present, completely independent of the cell; not approximating to vein 7.

Fore-legs with a tibial epiphysis. Tibiae of middle legs 2-spurred. Posterior tibiae 4-spurred; not hairy.

Eggs, larvae and pupae. Eggs smooth or minutely pitted (?). Larval prolegs 2, or 4–8. Larvae case-bearing (invariably, sometimes boring into the leaf or fruit to which it is attached); concealed feeders (mining when young, subsequently living in a portable case). On divers Dicot trees, shrubs and herbs, and a few on Gramineae, Cyperaceae and Juncaceae.

Pupae concealed; above the ground. Empty pupae not becoming protruded.

British representation. Genera 4; about 100 species (1 adventive). Coleophora alcyonipennella (Frisch's Case-moth, Clover Case-moth), Coleophora laricella (Larch Case-moth), etc.

Classification. Microlepidoptera. Suborder Ditrysia. Superfamily Gelechioidea.

Comments. Antennae porrect in repose.
