Definition
Meleonoma facialis is a species of moth in the family Cosmopterigidae, order Lepidoptera.
Overview
The species belongs to the genus Meleonoma, which comprises small, often intricately patterned moths distributed primarily in the Palearctic and Oriental regions. M. facialis was formally described in the early 2000s based on specimens collected in China. The available literature places the species within the diverse micro‑lepidopteran fauna of East Asia, but detailed information on its full geographic range and ecological preferences remains limited.
Etymology/Origin
The generic name Meleonoma is derived from Greek roots—mele meaning “song” or “melody” and -noma meaning “law” or “custom”—a construction historically used in taxonomy without a precise literal meaning. The specific epithet facialis is Latin for “pertaining to the face,” likely referring to distinctive markings or coloration on the moth’s head or forewing pattern observed by the describers.
Characteristics

Taxonomic placement:
- Kingdom: Animalia
- Phylum: Arthropoda
- Class: Insecta
- Order: Lepidoptera
- Family: Cosmopterigidae
- Genus: Meleonoma
- Species: M. facialis
-
Morphology: As with other Meleonoma species, adults are small (forewing length typically 5–8 mm). The wings are narrow with a glossy appearance and display characteristic scale patterns; the species name suggests a notable facial or frontal marking, though the exact pattern is not described in widely accessible sources.

Life history: Specific host plants, larval biology, and phenology have not been comprehensively documented for M. facialis. Members of Cosmopterigidae often feed on plant detritus, seeds, or live tissue, but the precise ecological role of this species remains unverified.
-
Distribution: Confirmed records are limited to China; the precise provinces or habitats have not been extensively reported in publicly available databases.

Note: Detailed morphological descriptions, ecological data, and distributional records for Meleonoma facialis are sparse in the publicly available literature. Consequently, certain aspects of the species’ biology remain unconfirmed.
