Description.

Male holotype (WAM21905): Body length 14 mm, forewing length 9.2 mm, head width 5.0 mm.

Structure: Inner orbits of eyes diverging above; head wider than long; clypeal protuberance in profile 0.32 × eye width; mandible with subapical tooth; F1 equal to combined length of next 2 flagellomeres; F1 0.75 × as long as scape; F2 0.53 × as long as F3; F3-F10 1.2 × as long as wide; last flagellomere 0.83 × as long as F1; marginal cell length 0.76 × distance from apex of cell to wing tip; cu-v of hind wing 1.3 × length of second abscissa of M+Cu; S5 with apicomedial emargination triangular, 2.9 × as wide as deep; S6 with apicomedial emargination three times as wide as deep.

Genitalia: penis valves with well extended shoulders; volsella elongated with circa 20 setae of variable length (Fig. 3H ); gonocoxa laterally with a few short setae; apex of gonocoxa with acute lobe ventrally; outer gonostylus truncated, short with robust setae on inner surface; inner gonostylus very small, rounded, with setae; S7 (Fig. 3E ); S8 apex straight, a few short setae around the mid line (Fig. 3F ).

Pubescence: Head pale yellow, darker on frons and vertex, some black hairs around ocelli and vertex; scutum, scutellum and metanotum with pale orange intermixed with black hairs; mesosoma laterally and ventrally pale orange; fore leg pale orange, mid and hind legs: coxa, trochanter, and inner surface of femur, tibia, and metatarsus with dark brown pubescence, outer surface pale orange; metasomal terga with pale orange hairs, T2 anteriorly with narrow band of black hairs; T6 posterior margin bare; S1-S5 with sparse rows of dark hairs near premarginal line and pale hair bands on posterior margins laterally; S4 apicomedial area with elongated patch of black anteromedially-directed bristles, patch width circa 0.4 sternum width; S5 with area preceding the emargination covered in long branched posteromedial directed hairs; S5 laterally with plumes of long orange hairs; S6 with smooth and shiny posterior margin almost without hairs.

Colouration: Integument of head black, apart from: scape ivory below; flagellum brown; labrum ivory with small brown marks in dorsolateral corners; clypeus ivory; supraclypeal area with ivory triangle; paraclypeal area ivory; mandible ivory at base, black at tip; proboscis orange-brown; mesosoma and metasomal terga black; mid and hind coxa, trochanter and femur and inner surface of tibia; front legs, metasomal sterna and posterior margins of metasomal terga orange.

Female allotype (WAM21904): Body length 15 mm, forewing length 10.2 mm, head width 5.3 mm.

Structure: Inner orbits of eyes diverging above; head wider than long; clypeal protuberance in profile 0.73 × eye width; mandible with subapical tooth; F1 equal to combined length of next 3 flagellomeres; F1 0.86 × as long as scape; F2 0.75 × as long as F3; F3-F10 circa as long as wide; last flagellomere 0.66 × as long as F1; marginal cell length 0.65 distance from apex of cell to wing tip; cu-v of hind wing 0.93 × length of second abscissa of M+Cu; S6 with raised area and parabolic posterior ridge (Fig. 3L )

Pubescence: Head pale yellow, darker on frons and vertex, some black hairs around ocelli and vertex; scutum, scutellum and metanotum pale orange intermixed with black hairs; mesosoma laterally and ventrally pale orange; fore leg orange; mid and hind legs: coxa, trochanter and inner surface of femur, tibia and metatarsus with dark brown to black pubescence, outer surface orange; metasomal terga orange, T2 anteriorly with a few black hairs at anterolateral corners, T5 with black prepygidial fimbria, T6 with strong black hairs flanking the pygidial plate; S1-S5 with rows of black hairs near premarginal line; hairs on S4 and S5 much longer and denser than on previous sterna.

Colouration: Integument of head black, apart from: scape with ivory streak below; flagellum brown; labrum ivory with brown marks in dorsolateral corners; clypeus ivory with two small brown marks; supraclypeal area and paraclypeal area black; mandible ivory at base, black at tip; proboscis brown, mesosoma and metasomal terga black; mid and hind coxa, trochanter and femur and inner surface of tibia; metasomal sterna and posterior margins of metasomal terga orange.
