Oecetis multipunctata Ulmer, 1916: 19 . — Mosely and Kimmins,

1953: 293, fig. 206.

Material examined. 48 samples in ANIC and NMV.

Diagnosis. Wings with pattern of dark spots (Fig. 30); forewing length about 4.5 times maximum width, fork 1 with footstalk and veins of the posterior anastomosis clearly stepped. In male genitalia (Figs 31–33) segment X simple, short and slender; inferior appendages without any lobes or processes, length about 3 times width, tapered distally; and phallus curved downwards.

Distribution. Widespread in northern and eastern Qld, and also collected from north-eastern NSW (Fig. 110).

Remarks. Oecetis cepaforma , O. dostinei and O. parka also have spotted wings, but O. cepaforma and O. dostinei have the forewings broad and ‘floppy’ compared to those of O. multipunctata and O. parka . These last two species are distinguished by male genitalic features, particularly the presence of the digitate laterobasal lobe on the inferior appendages of O. parka , and the more rounded, rather than angular shape of the inferior appendages of O. multipunctata . The male genitalia of Oecetis multipunctata closely resemble those of the NT O. brevidentata from which O. multipunctata is distinguished by its spotted wings and shape of the phallus. Also in O. multipunctat a, in lateral view, the inferior appendages are almost straight, whereas in O. brevidentata sp. nov. the apices are down-turned.
