Copromorphidae, the "tropical fruitworm moths" is a family of insects in the lepidopteran order. These moths have broad, rounded forewings, and well-camouflaged scale patterns. Unlike Carposinidae the mouthparts include "labial palps" with the second rather than third segment the longest. The position of the enigmatic New Zealand genus Isonomeutis in this family in uncertain, as it lacks the flimsy cuticle of the pupa characteristic of other Copromorphoidea. With other unusual structural characteristics of the caterpillar and adult, it could represent the sister lineage of all other extant members of this superfamily (Dugdale et al., 1999). The genus Sisyroxena from Madagascar is also notable for its unusual venation and wing scale sockets (Dugdale et al., 1999).
