The family Arctiidae belonging to superfamily Noctuoidea, it was divided into three subfamilies: Lithosiinae, Arctiinae, and Syntominae (Kitching and Rawlins, 1999; Conner, 2009). The family include 11,155 species of 750 genera worldwide (Heppner, 2005). About 6000 species distribute in the Neotropics but the family is represented in all the main zoogeographical regions (Scoble, 1992). Taxonomic study of the Arctiidae in Cambodia has been done by a few foreign entomologists. As the results of this study, about 90 species of 40 genera belonging to Arctiidae were recorded from Cambodia, most of them are recorded for the first time in Cambodia. 21 species are briefly redescribed in this study such as: Nyctemera coleta (Boisduval, 1832), Brunia antica (Walker, 1854), Darantasia cuneiplena (Walker, 1859), Eilema longpala (Holloway, 2001), Cabarda sequens (Walker, 1862), Lyclene lutara (Moore, 1859), Teulisna steineri (Holloway, 2001), Cyana obliquilineata (Hampson, 1900), and Cyana quadrinotata (Walker, 1897), etc.
