Genus Chasminodes Hampson, 1908

Chasminodes Hampson, 1908, Catalogue of the Lepidoptera Phalaenae in the British Museum 7: 4. Type-species: Acontia albonitens Bremer, 186, by subsequent designation by Hampson, 1910.

Chasminodes represents a rather homogenous genus of the tribe Cosmiini, subfamily Xyleninae with 17 species predominantly of Manchurian and partially Oriental distribution. The species are characteristic components of Manchurian broad-leaved and mixed forests in the Far East, and in some years the larvae appear in great abundance and seriously damage lime ( Tilia) trees. Hampson (1910) referred only five species to the genus: C. atrata, C. nervosa, C. nigrilinea, C. cilia and C. albonitens . Sugi (1955, 1956) revised the C. albonitens complex in Japan and named five new species. Subsequently, two new species were described by Yang (1964) from China, two by Kononenko (1981, 1982) from Japan and Russian Far East, one by Chen (1986) from China and one by Behounek (1995) from North Vietnam. The Far Eastern species of the genus were revised by Kononenko (1982), the Korean species by Shin & Choi (1993), and those from North China by Han et al. (2003).
