P., Campground, 18°09′08.9′′S, 145°48′54.4′′E, 120 m, e. l., 15.IV.2013, B. Mollet & G. Tarmann leg. (BMC).
Discussion and differential diagnosis. At Murray Upper Falls N. P. a series of larvae were collected on Hibbertia scandens (Figs 30, 31). One specimen obtained from a larva and one specimen collected at UV light have the ratios and the head feature of P. angustifrons, the other specimens (Fig. 32) obtained from larvae have larger frons and smaller compound eyes. Their head ratios are constant and different from those of the other species in Group 1 (Table 3) and from P. angustifrons (Table 2). This difference as well as the sympatry with P. angustifrons justifies the description of these specimens as a new species.

Description. Male, holotype. Length of body: 5.2 mm; length of forewing: 6.4 mm; breadth: 2.4 mm; length of hindwing: 4.5 mm; breadth: 2 mm; length of antenna: 4.5 mm; distance between compound eyes in frontal view, 1.50 x the breadth of compound eye and 0.95 x the height; compound eye black almost circular in lateral view; ocellus slightly ovoid; chaetosemata long and narrow occupying all the space between compound eye and ocellus. Antenna: brown with satin sheen, segments 1 to 25 bipectinate, 26 to 37 biserrate, pectinations of maximum length at segment 10, about 5x longer than breadth of shaft in dorsal view. Body: frons brown with greenish blue metallic sheen, vertex brown, edging of blue metallic scales bordering the compound eyes; proboscis yellowish brown, brown labial palps upcurved; patagia and proximal part of tegulae covered with green metallic scales; thorax brown dorsally, strong blue metallic sheen ventrally; abdomen brown, segments 3–8 green metallic sheen dorsally, brown ventrally. Forewing: brown with satin sheen upperside, light brown underside. Hindwing: brown with slightly translucent area medially, underside with few shiny blue scales anteriad of medial stem and at anal angle. Legs and coxae: brown with strong green metallic sheen.
Male genitalia (Fig. 34). Valva slightly triangular, distally convex dorsally and slightly ventrally, pointed apically. Phallus nearly x4 longer than broad, slightly upcurved, half proximal part cylindrical, distal half conical, cornutus as long as phallus.
Females are not included in the description due to the doubtful differentiation from those of Pollanisus angustifrons that is sympatric with larvae collected at the same time on the same larval host plants.
Phenology and bionomics. No imagines were collected flying or resting on plants. All were collected in larval stages.
Etymology. This species is named in honour of the Jumbun Aboriginal community living around Murray Falls.
