Deltoplastis balanitis is a moth in the family Lecithoceridae. It was described by Edward Meyrick in 1910. It is found in southern India.[1]
The wingspan is 26–27 mm. The forewings are fuscous partially tinged with whitish ochreous and with a small blackish-fuscous spot on the base of the costa, as well as a blackish-fuscous blotch extending along the dorsum from one-sixth to three-fifths, anteriorly rounded and reaching half way across the wing, narrowed to a point posteriorly, edged with ochreous whitish. The first discal stigma is indicated by a small round blackish-fuscous spot resting on this. There are two blackish-fuscous dots on the transverse vein, partially whitish edged. There is also a blackish-fuscous triangular blotch with the apex touching these dots, the base rather near and parallel to the termen, edged posteriorly by a band of whitish-ochreous suffusion. There is a dark fuscous terminal line. The hindwings are fuscous, anteriorly paler and tinged with whitish ochreous.[2]
