Gelechiidae

Adults small; relatively long-bodied; 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 (usually), or rough (e.g., Nothris). Antennae of medium length to long; extending to about 0.75–0.8 times the length of the forewing. Antennae of males simple; shortly simply-ciliate, or non-ciliate. The antennal scape with a pecten (rarely), or without a pecten; not forming an ‘eye cap’. Ocelli present (often), or absent. Chaetosemata absent (?). Maxillary palps well developed, or much reduced (short, appressed); 4 segmented; folded. Labial palps ascending (long, recurved, with a slender, pointed terminal segment); 3 segmented. Proboscis fully developed; scaly towards the base.

Wingspan 8–20 mm; about 11–14 times the thoracic width. Forewings narrow; 2.9–5.5 times as long as wide. Tornus weakly defined to undetectable. The outer margin convexly curved; forewings apically blunt; forewings predominantly shining-metallic (e.g., bronzy), or exhibiting shining-metallic markings (e.g., sometimes with silvery or leaden spots), or neither shining-metallic nor with shining metallic markings. Hindwings narrow-elongate and very long-fringed to neither unusually narrow-elongate nor especially long-fringed; trapezoidal; quite markedly narrower than the forewings to markedly broader than the forewings; with a pointed apex to with a rounded apex. The fringe of the hindwings (0.5–)1–3 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 12 veined (often), or 10–11 veined (veins 3 and 4, and 7 and 8 sometimes coincident, veins 2, 4 and 7 sometimes absent); with 1 anal vein. The anal veins of the forewings representing 1b only. Forewings lacking a tubular vein 1c. Vein 1b of the forewings furcate proximally. Forewings with a discal cell, or without a discal cell (e.g., Stenolechia). The transverse vein complete, or incomplete, or lacking. Discal cell of the forewings without a tubular media (M) vein. Hindwings (9–)10 veined; with 1 anal vein to with 3 anal veins. The anal veins of the hindwings representing 1b only, or comprising 1a and 1b, or comprising 1a, 1b and 1c. Hindwings exhibiting vein 1a, or lacking vein 1a; exhibiting a tubular vein 1c, or lacking a tubular vein 1c. Vein 1b of the hindwings obsoletely furcate, or simple. The transverse vein complete. The hindwing cell bearing a pecten of hairs on its cubital margin, or without a cubital pecten of hairs. 6 veins arising from the hindwing cell. The cell-derived hindwing veins all arising independently of one another, or 3+4 proximally joined and 6+7 proximally joined (with connation or stalking). Veins 6 and 7 of the hindwings not parallel. Vein 8 of the hindwings completely independent of the cell, or joined to the cell only by a bar, or anastomosing with the upper margin of the cell; not approximating to vein 7.

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

Eggs, larvae and pupae. Eggs smooth or minutely pitted (?). Larval prolegs 10 (rarely all much reduced). Larvae case-bearing, or not case-bearing; concealed feeders (mostly in spun leaves, fruiting infloresences, flowers or shoots); subterranean (rarely), or not subterranean; leaf-mining (rarely), or not leaf-mining. One in bracken stems, a few associated with conifers. Otherwise mainly associated with divers Dicot trees, shrubs and herbs; seemingly avoiding Monocots, except Sitotroga cerealella, which is a destructive pest in stored cereal grain.

Pupae concealed; on the surface of the ground, or above the ground. Empty pupae not becoming protruded.

British representation. Genera 54 (4 adventive only); about 150 species (8 adventive). Gelechia rhombella, Hypatima rhomboidella (Lobster-clawed Moth), Prolita sexpunctella (Long-horned Flat-back, Groundling), etc.

Classification. Microlepidoptera. Suborder Ditrysia. Superfamily Gelechioidea.
