Definition
Zatrephes bilineata is a species of moth in the family Erebidae, subfamily Arctiinae.
Overview
The species belongs to the genus Zatrephes, which comprises a group of neotropical tiger‑moths. Like other members of the genus, Z. bilineata is presumed to be nocturnal and associated with forested habitats in Central and South America. Detailed distribution records, life‑history information, and ecological data for this species are limited in the literature.
Etymology / Origin
The specific epithet bilineata derives from the Latin bi‑ (“two”) and lineata (“lined”), likely referring to a characteristic pattern of two longitudinal lines on the wings or body of the moth. The generic name Zatrephes was established by Jacob Hübner in the early 19th century; its exact linguistic origin is not definitively recorded but follows the convention of classical‑styled taxonomic names.
Characteristics
While precise morphological details for Z. bilineata are not comprehensively documented, members of Zatrephes generally exhibit:
- A wingspan ranging from 30 to 50 mm.
- Forewings with vivid coloration, often incorporating contrasting bands or spots.
- Hindwings that may be paler, sometimes with a subtle pattern.
- A robust, hairy body typical of Arctiinae moths.
The name bilineata suggests that the species displays two prominent linear markings, but verification of this trait in specimens is lacking.
