LT: ♁ (n = 3): 9.8 mm (9.4–10.1); ♀ (n = 5): 10.8 mm (10.5–11.2); BV/LV = 4.0; BF/LF = 1.71; LP+LM/BT = 0.71; LTg/BTg = 2.1–2.3; LW/BW = 1.72. Male HEAD (Fig. 47A–D). Vertex concave, with anterior and posterior margins parallel, curved; dark brown variegated with yellowish in middle. Frons black-brown, slightly tinged with 2 transverse, irregular, variegated yellowish markings, more dorsal one not reaching sides. Clypeus elongate, dark reddish brown with 2 short, black, longitudinal lines at base, with apex darker. Genae yellowish with brown markings around eyes and under antennae. Labium brown, reaching metacoxae. Antennae black; scape short, ring-shaped; pedicel subcylindrical, slightly narrowing towards apex. THORAX (Fig. 47A–C). Pronotum dark brown with some yellowish markings laterally; slightly transversely wrinkled posteriorly; obsolete median carina and 2 small impressed points on disc. Lateral fields of prothorax brown. Mesonotum dark brown with reddish markings along posterior margin, median yellowish spot along anterior margin and at apex of scutellum; slightly rugulose; median and peridiscal carinae weakly marked; median carina ending before scutellum; slight impression before scutellum. Red ventrally. Tegulae brown. TEGMINA (Fig. 47A, C). Dark brown with small yellowish or reddish spots; bigger, whitish, slightly transverse spot on middle of clavus; large triangular white marking on costal margin on nodal line and a smaller one anterior to it; white marking at apicosutural angle. Maximum breadth at nodal line; costal margin slightly sinuate; apical margin obliquely rounded. POSTERIOR WINGS (Fig. 47E). Brown with apical 1⁄2 black-brown; transverse, subtriangular white marking at apicocostal angle, extending on 5 cells; sutural margin broadly bordered with yellowish on basal half; orange marking between anal fold and vein CuA at about half length. Margin of anal area sinuate; sutural margin with 2 clefts, cubital one slightly marked. LEGS (Fig. 47A–D). Pro- and mesocoxae reddish brown. Pro- and mesofemora black-brown with yellowish spots marking 2 obsolete rings. Pro- and mesotibiae black-brown with 3 obsolete ring-shaped yellowish markings, larger one near apex. Pro- and mesotarsi dark brown, with basal half of last segment yellow-brown. Metacoxae reddish; metafemora reddish with apex brown. Metatibiae brown, with 3 lateral spines yellowish basally and 8 apical, black-brown spines. Metatarsi brown with a ventral row of 6 black spines on first tarsomere. ABDOMEN. Bright red with genital segments black-brown. MALE GENITALIA (Fig. 48). Posterior margin of pygofer in lateral view strongly sinuate, roundly projecting at dorsal 1⁄2, rather broad ventrally (Fig. 48A, C). Anal tube elongate, 2.25 times as long as broad, with basal 1⁄2 parallel-sided and narrower, then broadly ovate with posterior margin notched; slightly sinuate in lateral view; lateral margins slightly curved ventrally on apical 3⁄4 (Fig. 48A–B). Gonostyli fused to nearly half length of centroventral part and projecting posteriorly (Fig. 48A, C). Centroventral part dorsoventrally flattened on basal 1⁄2, then abruptly narrowing and forming strongly elongated and narrow process, slightly diverging and ending in a small hook pointing dorsally; process slightly sinuate in lateral view (Fig. 48A, C). Laterodorsal part of gonostyli curved lateroventrally, hooked, with lateral process rather broad and moderately elongated, about as long as spoon-shaped process (Fig. 48A, C–D). Dorsal portion of phallobase with elongate process on each side, strongly narrowing on basal half in lateral view, then strongly hooked, pointing dorsally and slightly incurved (Fig. 48E–F). Ventral portion of phallobase along lateral margin of phallus on basal half, elongate and supassing phallus, crossing after it (Fig. 48E–F). Phallus dorsoventrally flattened, elongate, narrowing from base to apex (Fig. 48E–F). Female Similar to male, but darker; frons entirely black-brown; white markings on tegmina smaller; blackbrown area of posterior wings larger, orange marking reduced (Fig. 49). Distribution and biology This species is known from a series of ten specimens collected in Chillagoe in North Queensland (Fig. 3), in the Einasleigh Upland Savanna bioregion. Nine specimens were collected on a single day in March; hence, the species is probably not scarce in its habitat. No host plant is recorded.
