Etymology

This species is named after the dark orange colouration of the face and mesosoma . The colour reminds of the notorious tourist visiting Australia and getting sunburnt already on the first day.

Diagnosis

(Male unknown). Forewing length 3.6–4.5 mm (holotype: 4.3). Antenna in females with 31–36 flagellomeres (32). Head between eye and antennal base flat, without protrusion. Ocelli of female not enlarged. Mesoscutum as long as wide. Mesopleuron weakly to distinctly coriaceous between strong punctures, on upper half with some striae and with moderate impunctate area around speculum. Area superomedia of propodeum slightly to strongly elongate, usually 1.2–2 times as long as wide; areas of propodeum smooth and shining between strong punctures. Portion of ovipositor that protrudes from metasoma 1.0–1.1 (1.1) times as long as hind tibia.

Description

Head Clypeus moderately large, convex when viewed from the side, margin convex; mandibles with lower tooth longer than upper tooth. Occipital carina complete, evenly arched or slightly angled above. Genal carina joining oral carina briefly before reaching base of mandible. Whole head coriaceous and matt, face and clypeus with dense and strong punctures, vertex with some sparse punctures. Antenna with last flagellomeres about as long as to shorter than wide, scape excised at an angle of about 50°.

Mesosoma Pronotum with epomia often indistinct; mesoscutum with notauli weak and barely reaching behind level of tegula; mesopleuron with sternaulus deeply impressed; scutellum not carinate. Propodeum with complete set of carinae, longitudinal carinae sometimes weak medially; metapleuron with short vertical carina arising above mid coxa. Mesosoma smooth and shining and with strong and dense punctures, mesoscutum but not scutellum coriaceous between punctures. Wings slightly tinged, radial cell along anterior margin of wing 0.95–1.25 times as long as stigma, areolet large, almost rhombic; hind wing with veins Cu1 and distal abscissa of vein 1A absent or very weak. Legs simple, hind coxa coriaceous and matt.

Metasoma First tergite 1.6–1.8 times as long as second tergite, second tergite 1.6–1.9 times wider apically than basally. First tergite with rather shallow but long glymma, petiolus flattened; first sternite reaching to about half length of tergite, its sides parallel. Third tergite with laterotergite separated by a crease at most at base; metasoma weakly compressed from tergite 3 onwards. Tergites smooth and shining, almost impunctate, tergites 1 and 2 with weak longitudinal striae or leather-like sculpture. Ovipositor weakly down-curved, laterally compressed, with subapical notch.

Colouration of female

Head dark orange, darkened on back of head except along outer eye margins, yellow in malar space, antenna dark brown in basal third, yellow or ivory medially and black apically. Mesosoma dark orange, legs orange, hind leg dark brown except for orange joints and trochantellus; forewing with stigma often lighter in anterior half. Metasoma dark brown to black, often slightly lighter on tergites 2 and 3.
