Teldenia latilinea is a moth in the Drepanidae family. It was described by Watson in 1961. It is found on Sulawesi. The length of the forewings is 10-11 mm for males and 9.5-13.5 mm for females. The fringe and costa are white and the forewings have a double greyish-brown postmedial fascia, continuing medial in position to the hind edge. The inner postmedial fascia is lunulate and the outer postmedial fascia usually broken. There is a greyish-brown subterminal fascia, which is sometimes reduced to spots between the veins and there are dark brown terminal spots between the veins. The hindwings have the same greyish-brown fasciae as the forewings, but continuous.
