Copromorphidae

Definition

A family of small moths in the order Lepidoptera, commonly called tropical fruitworm moths. Members are characterized by broad, rounded forewings with cryptic scale patterns, and distinctive labial palp morphology in which the second segment is elongated rather than the third—a trait that separates them from the related family Carposinidae. The family exhibits unusual structural features in both adult and larval stages, leading to hypotheses that it may represent the sister lineage to all other extant members of the superfamily Copromorphoidea.

Etymology

From Greek kopros (dung, excrement) + morphe (form, shape), with the family suffix -idae; the name refers to larval habits rather than adult appearance.

Example

The genus *Sisyroxena* from Madagascar, placed in Copromorphidae, shows highly modified wing venation and distinctive scale socket structures that have prompted reevaluation of character polarity within Copromorphoidea.

Synonyms

• tropical fruitworm moths

Usage Notes

Distinguished from Carposinidae (fruitworm moths) primarily by palp segmentation and larval morphology; both families are often treated together in superfamily Copromorphoidea. The family's phylogenetic position remains under study due to its mosaic of plesiomorphic and apomorphic traits.
