Introduction

Ptycta johnsoni is one of four species of Ptycta from Japan. This species lives in subtropical regions (see distribution map) and inhabits trees at the edge of forests and in populated areas.

Characteristics

Ptycta johnsoni can be distinguished by:

• Forewing with wide basal band and nodal band, pigmentation on anterior margin and apical ¹/₃ of pterostigma.
• Male genitalia: Basal paraproct lobe short in anterodorsal orientation, posterior lobe of paraproct rounded, dorsal corners of hypandrium reduced; phallosome long with narrow basal margin.
• Female genitalia: Sclerite of subgenital plate with broad triangular anterior margin. Distributed from Okinawajima Island to Tsushima Island.
