Thyatira Ochsenheimer

Type species: batis Linnaeus.

Synonyms: Strophia Meigen (type species batis); Calleida Sodoffsky (unnecessary replacement name for Thyatira).

The rather simplified 'peach-blossom' pattern of the forewings distinguishes the genus from related Thyatirini such as Horithyatira Matsumura. The patches are large, set against a dark brown ground, and are apical, subapical, basal, tornal and, on the dorsum, central.

The male genitalia are of simple, typically thyatirine form, the valves relatively small with a spur on the ventral margin at the distal end of the sacculus, the praesacculus of Werny (1966). The aedeagus has a strong, acute, apical spur (Haken of Werny). The female genitalia are typical of the Thyatirinae.

The larva of the type species, illustrated by Sugi (1987), is mottled rich brown with five to six darker lateral patches, each edged obliquely anteriorly by a fine white line that also extends along the curved dorsal border of the patch. The host-plant is Rubus (Rosaceae).

The genus is widely distributed through the Palaearctic and the mountains of the Oriental tropics (except Sulawesi). It also extends into the New World to as far south as Peru.
