Abstract
The bombycid genus Prismosticta was established by Butler in 1880 with P. fenestrata as its type species. The genus is mainly distributed in Asian countries: Vietnam, Thailand, Cambodia, China, India, Indonesia, Japan, Malaysia, Myanmar (Holloway, 1987; Chu & Wang, 1993, 1996; Zolotuhin & Witt, 2009). Recently, Kishida & Wang (2011) synonymized P. sinica Yang, 1995 with P. fenestrata Butler, 1880, leaving five species in the genus. Chu & Wang (1993) described 'Prismosticta unihyala' based on two malespecimens collected from the Wuyishan Mountains, Fujian Province, China, but it is distinctly separated from other Prismosticta species by the following characters: uncus with a long dorsal uncuslike projection arising from the base of uncus, and valvae asymmetrical. We consider that 'Prismosticta unihyala'' does not belong to any named genus, and will address this issue elsewhere.
