Dudgeonea falcata sp. n. (Plate 6, Fig 84) GG 12mm, EE 20mm. The general coloration and markings of the wings are typical of the genus, except the forewings are relatively narrow, slightly falcate at the apex rather than rounded. The clusters of white patches on the forewing are more restricted, the more basal group extending along most of the dorsum in the female, and peaking interiorly at one third in both sexes, whereas the group is mostly clear of the dorsum in other Indo-Australian species: linking with a costal area in leucosticta Hampson and forbesi Roepke (New Guinea, Timor); forming an ovate central area in actinias Turner (N. Australia). The apical patch of the forewing has far fewer spots in the male than in other species, and the female has a marginal array somewhat as in actinias. The hindwings are irregularly streaked with rich brown running into the base from the margins, and the female has the apical area with an archipelago of white patches as in the forewing; the wings are much more uniform in the other species, where the abdomens are the same general colour as the hindwing, but dark brown in falcata, matching the margins. The male genitalia are very similar to those of leucosticta but have the uncus slightly longer relative to the gnathus, and valves that are narrower without being expanded centrally. |
