Desmia odontoplaga is a moth in the family Crambidae described by George Hampson in 1898. It is found in Panama[1] and Brazil (Paraná, Lower Amazons).[2]
The wingspan is about 20 mm. The forewings are fuscous brown with a cupreous tinge. There is an elliptic white spot in and below the middle of the cell with a speck beyond its lower point and an obscure line from it to the inner margin, as well as a white postmedial patch. There is a large medial white patch on the hindwings.[3]
