Ditrigona paludicola sp. n.

Ditrigona paludicola

8mm. The wings are fasciated and marked irregularly with grey on white more as in 'Zusidava' serratilinea than in typical Ditrigona as discussed above. The wing margins are rounded, that of the hindwing slightly produced centrally, unlike in serratilinea and the genera Zusidava Walker (discussed next) and Pseudomodesa Warren (New Guinea) where they are distinctly angled. The male antennae are bipectinate (unipectinate in serratilinea and the type species of the other genera; variable in Ditrigona). The fascia intermediate between the postmedial and submarginal is broken, with its strong patches repeated at the margin on the forewing. The male genitalia have the socii and uncus lobes broadly rounded, giving a four-lobed appearance to the distal part of the tegumen: the uncal lobes are smaller than those of the socii. The valves are reduced, falcate, setose, with rather quadrate, setose, basal interior processes to the sacculus. The eighth abdominal segment is box-like with several longitudinal bands of sclerotisation.
