Cotana rosselliana is a moth in the family Eupterotidae. It was described by Walter Rothschild in 1917. It is found in New Guinea.[1]
The wingspan is about 54 mm for males and 65 mm for females. The basal three-fifths of the forewings of the males is orange brown, while the outer two-fifths are paler more suffused with yellow. There is a broad irregular subbasal dark-brown band followed by a dull yellow stigma ringed with dark brown and a curved median black-brown band, as well as three crenulate black lines of varying sharpness in outer the two-fifths and a dark-brown patch below the apex. Females have saffron-yellow forewings with a round white spot below the median in the basal one-third and there is a crenulate lunate transverse postdiscal white band. The hindwings are saffron yellow with a lunate postdiscal white line.[2]
