Rhodoprasina viksinjaevi Brechlin, 2004, Arthropoda 12(3): 8. Type locality: China, Hunan, Nanling Shan, 1500m (24°54'N, 112°57'E).
Wingspan: 82-100mm. Similar to R. corrigenda Cadiou & Kitching, 1996, from Thailand, but smaller and without the silvery sheen to the greenish forewings, which have a bluish tint instead. These are also shorter and more blunted apically. Hindwing pink basal area extending to the centre of the wing (Brechlin, 2005).
Little known. Males will come to light in large numbers between 19.00h and 03.00h. This is in distinct contrast to other members of the genus, which appear to fly for only a short period after dusk (Brechlin, 2005).
China: 15-30.xi (Hunan); 6.xii (Guangdong).
Larval hostplants. Unknown, but the related R. floralis (Butler) from northern India has been recorded from Acer campbelli (Aceraceae) (Fellowes-Manson, 1906).
China: Hunan (Nanling Shan); Guangdong (Nankunshan).
So far, only known from southeastern China (Guangdong and Hunan).
