This species is named in memory of a hiking trip to Tasmania together with Jana Rogasch, Farid Anwari, Lovisa Rosnäs, Bjørn Dueholm and Emilie Roy-Dufresne. We encountered a lot of mud in the Tasmanian wilderness, and it came in every possible shade of brown, just like this species. It also occurs in Tasmania, and thus gets the name from the Latin word for ‘muddy’.
Forewing length 3.2–4.2 mm (holotype: 4.2). Antenna in females with 30–34 (32) flagellomeres, in males with 28–30.
Head between eye and antennal base flat, without protrusion. Ocelli of male not to slightly enlarged, distance of hind ocellus to compound eye about 1.2–1.6 times diameter of ocellus. Mesoscutum slightly shorter than to about as long as wide. Mesopleuron strongly coriaceous especially on lower half, with rather weak punctures that are inconspicuous against matt background, with a few parallel wrinkles especially in anterior half and with small smooth area around speculum. Area superomedia of propodeum about as long as to distinctly longer than wide; areas of propodeum coriaceous and with some punctures, especially on dorsal surface. Portion of ovipositor that protrudes from metasoma 0.65–1.0 (0.85) times as long as hind tibia.
Head Clypeus moderately large, convex when viewed from 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 but rather weak punctures. Antenna with last flagellomeres about shorter than wide, scape excised at an angle of about 50°.
Mesosoma Pronotum with epomia indistinct; mesoscutum without distinct notauli; mesopleuron with sternaulus present but weak; scutellum not carinate. Propodeum with complete set of carinae, longitudinal carinae sometimes weak medially; metapleuron with short vertical carina arising above mid coxa. Mesosoma strongly coriaceous even medially on scutellum; punctures, where present, weak and almost disappearing against background sculpture. Wings hyaline to slightly tinged, radial cell along anterior margin of wing 0.8–1.1 times as long as stigma, areolet moderately large, almost rhombic; hind wing with outer veins reduced, usually not pigmented except at base. Legs simple, hind coxa coriaceous and matt.
Metasoma First tergite 1.45–1.8 times as long as second tergite, second tergite 1.4–1.9 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 crease at most at base; metasoma weakly compressed from tergite 3 onwards. Tergites smooth and shining, almost impunctate, tergites 1 and 2 with longitudinal striae and leather-like sculpture. Ovipositor almost straight to weakly down-curved, laterally compressed, with subapical notch; male clasper bluntly rounded.
Colouration of female
Head black, face, clypeus, mandibles and outer eye margins orange to yellow; antenna brown, lighter basally where it is often orange. Mesosoma including scutellum and propodeum orange to brown, mesoscutum black, dark markings at about mid-height of mesopleuron and dorsally on propodeum (extent of these markings varying considerably); legs orange, hind coxae often dark brown at base; forewing with stigma often lighter in anterior half. Metasoma dark brown basally, orange basally on tergite 3 and often also on posterior tergites.
Colouration of male
As in female, but with dark brown colouration on mesopleuron and proposeum often less extended, metasoma often mostly orange.
