Oecetis ornata Kimmins, 1962: 157–158 .

Material examined. Holotype. Male , Humbolt Bay, Dutch New Guinea [Irian Jaya] ( BMNH).

Male , Qld, 3 km ENE Mt Tozer, 12°44'S 143°14'E, 2 Jul 1986, J.C. Cardale ( ANIC) .

Diagnosis. Forewing ( Fig. 80 ) strongly and coarsely patterned, with dark brown markings on the proximal two-thirds. In forewing fork 2 sessile; in male genitalia, phallus with a sclerotised digitate process subapically on ventral side.

Remarks. The single male specimen available for study varies slightly from the type as illustrated by Kimmins (1962). However, given the proximity to New Guinea of the collecting locality in far northern Qld and that the species was described from a single male, the specimen is referred to O. ornata for the present. Differences are mainly genitalic — shape of the preanal lobes and of the inferior appendages in lateral view. Figures drawn from the Australian specimen are provided for comparisons (Figs 81–83).

Distribution. New Guinea and far northern Qld (Fig. 126).
