Tamba mnionomera is a noctuoid moth of the family Erebidae first described by George Hampson in 1926.[1]
This is one of the similar species, with a longitudinal dark streak on the forewing that meets the margin at its angle. T. mnionomera has a weaker streak, more lunulate fasciation, and greenish markings, particularly a spot in the center of the hindwing just distal to the postmedial.
It is found in Thailand and Sundaland. The species is frequent in the lowlands, found in a range of forest types and in disturbed habitats.
