Material examined. Holotype: male: Queensland, Dauan Island , Torres Strait; elevation 5 m, - 9.42 o, 142.53 o, 6–12.xii.2017, I. R. Johnson and P. R. Wilson, (in S. J. Johnson Collection located in the Museum of Tropical Queensland, Townsville, Australia, QM T241069 ) . Paratypes: 2 males, same data as Holotype ( QM T241068 , T250588 ) ; 1 male, - 9.42˚, 142.53˚, 12-17 December 2020 ( QMT 240992 ) ; 1 male, 9.42˚, 142.53˚, 31’47” E, 10 December 2017, P. R . Wilson and I. R. Johnson (in P. R. Wilson collection); 1 male, same location, 16 December 2020, P. R . Wilson and I. R. Johnson (in P. R. Wilson collection).

Description. Male (Holotype) ( Fig. 4A, B ): Forewing length 13 mm; antenna black with white bands on the underside; thorax and abdomen upperside black and underside white. Forewing upperside: dark blue; black margin narrow ~ 1mm along termen widening to ~ 2mm at apex; dorsum straight. Hindwing upperside: dark blue becoming narrowly greyish blue towards the costa; termen margin very narrow (~ 0.2–0.3 mm) black edged with very narrow white on the inner margin particularly towards the tornus; a subtornal submarginal black spot with a series of submarginal black spots along the termen decreasing in size towards the apex at veins Rsand M 1; tornus and costa brown; tail black with white tip. Forewing underside: uniformly pale brown; termen margin very narrow (~ 0.2 mm) black edged with very narrow white on the inner margin between the veins; terminal and subterminal brown bands between each vein narrowly edged with white; a post median band edged with beige, curved and distinctly stepped at each vein; a short medial band at end of cell edged with beige. Hindwing underside: uniformly pale brown; termen with very narrow black margin (~ 0.2 mm) edged with very narrow white on the inner margin between the veins; small tornal black spot edged with white adjacent to two subtornal black spots edged with orange and a few iridescent blue scale; terminal and subterminal brown bands curved between each vein narrowly edged with white; a post median band edged with beige distinctly curved and stepped at each vein, a short medial band at end of cell edged with beige, and a submedial band edged with beige distinctly stepped at each vein.

Male (Paratypes): As above except forewing length 13–15 mm.

Male genitalia. ( Fig. 5A, B, C ): Tegumen narrow, circular and band like. Vinculum narrow. Brachium curved and cylindrical with a blunt point. Socius on either side of the anus opening large, bulbous and semicircular in dorsal and ventral view, with numerous long hairs. Valva broad and spoon-like with a stout slightly curved dorsal projection above a semi-circular “toothed” indentation extending to a slightly curved very hairy posterior edge.

Etymolog y. From a Torres Strait Islander song about Roxin (Dauan Island) sung in the traditional Kala Kawa Ya language.

Ecology. Four specimens were collected over two days from 3:30 pm to 5:00 pm on 10–11 December 2017 and two specimens collected at 4 pm on 16 December 2020 on a dirt road through monsoonal vine scrub regrowth with a canopy to a height of approximately 5– 6 m. The area had been cleared previously and had remnants of abandoned banana and mango trees. The area is close to sea level and is subject to extended periods of waterlogging over the wet season. The life history is unknown.

Comments. The limited number of available specimens do not vary significantly in size, shape, colour or markings. Jamides phaseli and J. amarauge have been collected at the same location and are the only other described Jamides species previously collected on the island. The specimens flew rapidly and erratically, which made capture extremely difficult. Adults were seen only in the late afternoon and have not been collected elsewhere on the island despite fairly extensive collection over an extended period of time by a number of collectors.
