Prismosticta Butler, 1880 , Ann. Mag. nat. Hist. 6(5): 67. Type species: Prismosticta fenestrata Butler, 1880 , by original designation.

Diagnosis. Very similar to Prismostictoides, but can be distinguished based by the following features: forewing with outer margin more smoother; tranglular transparent spot near apex larger; uncus shallowly bifid with short finger-shaped or short tooth-shaped lobes; gnathos strongly sclerotized, medial lobe smooth or spinulose; valva symmetrical with blunt apex; aedeagus curved; vesica helical, with a single hook-like cornutus.

Distribution. China, Japan, Vietnam, Indonesia, Malaysia, Myanmar, Cambodia, Thailand, India. Remarks. At present, the genus consists of six species (Holloway, 1987; Chu & Wang, 1993, 1996; Zolotuhin & Witt, 2009; Wang et al., 2011), distributed in Asia. Four Prismosticta species are here recorded from China (Map 23).
