Apatetrinae
Meyrick, 1947
Tribe Guides
2Apatetrinae is a of small within the Gelechiidae, established by Edward Meyrick in 1947. The subfamily includes two recognized tribes—Apatetrini and Pexicopiini—plus numerous currently unplaced to tribe. Many are poorly known, though the group includes some economically significant pests such as the pink bollworm (Pectinophora gossypiella). The subfamily exhibits considerable diversity in and larval habits across its constituent genera.

Identification
Members of Apatetrinae are small to minute with the general gelechioid body plan: narrow wings, slender bodies, and relatively long . Distinguishing Apatetrinae from other Gelechiidae requires examination of genitalia and wing venation characters; no single external morphological feature reliably separates the subfamily. The two tribes within Apatetrinae are differentiated by subtle structural characters of the male genitalia and larval case construction in some groups.

Habitat
vary considerably across the diverse , ranging from arid and semi-arid regions to agricultural landscapes and native vegetation. Many occupy specific plant environments tied to larval feeding requirements.
Distribution
The has a worldwide distribution, with occurring across the Palearctic, Nearctic, Afrotropical, Oriental, and Australasian regions. Individual genera often show restricted geographic ranges; for example, several genera described by Janse are primarily southern African.
Host Associations
- Gossypium - larval Pectinophora gossypiella (pink bollworm) is a major pest of cotton
Human Relevance
The includes significant agricultural pests, most notably Pectinophora gossypiella (pink bollworm), which causes substantial economic damage to cotton crops worldwide. Some in related have been investigated for potential or monitored as minor crop pests.
Similar Taxa
- AnomologinaeCatalogue of Life treats Apatetrinae as a synonym of Anomologinae, indicating taxonomic uncertainty and close relationship between these concepts
- GelechiinaeLargest of Gelechiidae; distinguished by different genitalia structures and often broader wing shapes, though external similarity requires dissection for confirmation
More Details
Taxonomic instability
The classification of Apatetrinae remains unsettled. Catalogue of Life lists it as a synonym of Anomologinae, while other authorities maintain it as a valid . The tribal structure, particularly the placement of Pexicopiini, has been revised multiple times since Hodges (1986). Many southern African described by Janse remain poorly studied and their tribal placement is provisional.
Economic species
Pectinophora gossypiella is among the most economically damaging lepidopteran pests globally, with extensive research on its , resistance management, and programs. Sitotroga cerealella (Angoumois grain moth), sometimes placed in this , is a major stored grain pest.
