Teldenia strigosa is a moth in the Drepanidae family. It was described by Warren in 1903. It is found in New Guinea and on Goodenough Island. The length of the forewings is 12.5-15 mm for males and 14-15.5 mm for females. The forewings are white with the costa and fringe brown, buff or paler in females. The fasciae are dark buff, consisting of narrow sub-basal, broad postmedial and double subterminal fasciae, the latter with the outer line lunulate and the inner straight. In males, the postmedial fascia may be reduced to two or three rows of dots with the inner row reddish-buff. The hindwings have double postmedial and single lunulate subterminal fasciae.
