Head mostly brown to dark brown, sometimes with reddish tinge; antennal segment I yellow, reddish apically; segments II and III brown; segment IV brown, whitish apically; labium yellow with reddish tinge; pronotum, mesoscutum and scutellum brown to dark brown, often with reddish tinge; pleura mostly brown to dark brown; metathoracic scent gland evaporative area and metapleuron often reddish or with reddish tinge; clavus brown to reddish brown; corium and embolium yellow to pale brown with brown or reddish areas; embolium reddish apically; cuneus red or pale brown with distinct reddish tinge; membrane brown; legs mostly pale brown with red tinge; abdomen reddish brown. Surface and vestiture. See generic description. Structure and measurements. Body ca. 2.6-2.7 × as long as wide, ca. 2.8-3.0 × as long as pronotum width; head ca. 3.6-4.3 × as wide as long; vertex ca. 1.2-1.5 × as wide as eye; anterior view head ca. 1.3-1.4 × as wide as high; antennal segment I ca. 1.1-1.5 × as long as vertex, ca. 0.5-0.6 × as long as head width; segment II ca. 2.4-2.8 × as long as segment I, ca. 3.1-3.7 × as long as vertex, ca. 1.2-1.3 × as long as head width, ca. 0.9-1.0 × as long as pronotum width at base; segment III slightly shorter than segment I, and segment IV almost twice longer than segment III; pronotum ca. 1.7-1.9 × as wide as long, ca. 1.4-1.5 × as wide as head. Genitalia. Genital capsule triangular, without supragenital bridge (Fig. 4C ); parameres subequal to each other in size and very similar in shape, slightly curved and with swelling in basal half directed outwards (Fig. 4D-G ); phallotheca stronger sclerotised closer to apex than basally; ductus seminis short, its apical part widened and placed inside endosoma, somewhat sclerotised; endosoma not subdivided into vesica and conjunctiva, voluminous, with sclerotised area placed at right side and armed with small teeth (Fig. 4A, B ).

Female. Unknown.

Distribution.

Known only from Australian Wet Tropics (Fig. 15A ).

Collection methods.

The specimens were collected with flight intercept trap and pyrethrum knockdown.

Etymology.

The species is named for its red cuneus, ruber from Latin, meaning red.
