Dunira calcarea sp. n.
11-12mm. In facies this species resembles rubripunctalis Walker (see below), but lacking the greater emphasis of the darker reniform and lunules distad from the postmedial on the dorsum. However, the latter feature occurs in the hindwing. The submarginals are more irregular in course and further from the margin. The male genitalia are much more typical of the genus than are those of rubripunctalis, where the valves show bilateral asymmetry, particularly in the position of the distal lobes on the ventral margin and have a basal hair pencil and a complex transtilla, features all lacking in calcarea. The valve is closest in appearance to that of obliquilinea Hampson, but the spine at the centre of the costa is less curved, more appressed, and the small digitate process just ventral to it is slightly longer.
