Thyatiridae

Definition

A former family-rank taxon of moths, now treated as the subfamily Thyatirinae within Drepanidae (the hook-tip moths). Comprises approximately 200 species commonly called false owlet moths, distinguished by broad, rounded forewings with intricate patterns and a resting posture that superficially resembles true owlet moths (Noctuidae). Historically maintained as a separate family based on larval morphology and adult wing venation, but molecular and morphological analyses support its placement within Drepanidae.

Etymology

From the type genus Thyatira, itself derived from the ancient Greek city Thyatira in Lydia (modern-day Turkey).

Example

The genus Tethea, including Tethea or, was long classified in Thyatiridae but is now placed in Drepanidae: Thyatirinae based on shared apomorphies with hook-tip moths.

Synonyms

• Thyatirinae (current subfamily name)

Related Terms

• Drepanidae
• Noctuidae
• Lepidoptera
• Subfamily
• false owlet moth
• hook-tip moth
• Tethea

Usage Notes

The family name Thyatiridae persists in older literature and some regional checklists; current taxonomy treats this group as Thyatirinae. The common name 'false owlet moth' reflects convergent resemblance to Noctuidae, not phylogenetic affinity. Specialists should verify whether a source uses the historical family concept or modern subfamily concept when comparing species lists.
