Diagnosis
The species can be recognized by the following combination of characters:
(1) posterior margin of the lateroventral lobes of the pygofer (lvl) oblique and slightly sinuate in lateral view ( Fig. 24A View Fig ) and strongly tapering posterad in ventral view ( Fig. 24C View Fig ), inner margin of lobes concave in ventral view ( Fig. 24C View Fig ), ventral margin rounded in caudal view ( Fig. 24E View Fig );
(2) posterior margin of laterodorsal process of gonostylus (ldg) roundly emarginate, leaving a widely open angle between laterodorsal process and ventral process of gonostylus (vp) in lateral view ( Fig. 24A View Fig );
(3) crest of furcate process of periandrium (cfp) only along distal portion and not merging basally ( Fig. 26D View Fig ), in lateral view, tapering in distal portion ( Fig. 26E View Fig );
(4) laterodorsal process of periandrium (ldp) tapering in distal portion, sinuate, twisted and curved laterodorsad, slightly shorter than lateroventral process (lvp) ( Fig. 26D–E View Fig );
(5) lateroventral process of periandrium (lvp) dorsoventrally flattened only in basal portion and strongly curved laterad and tapering distally ( Fig. 26D–F View Fig );
(6) apicodorsal process of aedeagus (adp) weakly sinuate, weakly dilated then tapering distally and shorter than apicoventral process (avp) ( Fig. 26A–C View Fig );
(7) posterior wing with weakly marked whitish marking along sutural margin ( Fig. 22E View Fig ).
Etymology

Distribution and biology
The species is currently recorded from the northern portion of Cape York Peninsula, in the area north of the latitude of Cape Tribulation, and on Prince of Wales Island in the Torres Strait ( Fig. 5A View Fig ). Bioregion: Cape York Peninsula.
The examined specimens were collected in all months between April and July, and in November. The habitats indicated on the labels are “open woodland” and “ Eucalyptus / Melaleuca woodland” but no specific host plant was recorded.
