This wasp is dedicated to the Swiss grocery chain MIGROS for their commitment to biodiversity and sustainability. The logo of the chain, an orange ‘M’, is of the same colour as this wasp, which will hopefully motivate even further engagement for nature by MIGROS in the future.
Forewing length 4.6–5.5 mm (holotype: 5.5). Antenna with 32–34 flagellomeres in both sexes (33). Head between eye and antennal base flat, without protrusion. Ocelli of male not enlarged, distance of hind ocellus to compound eye about 1.5 times diameter of ocellus. Mesoscutum about as long as wide. Mesopleuron smooth and shining between strong punctures, with parallel wrinkles especially in anterior half, often with some restricted coriaceous areas and with moderate impunctate area around speculum. Area superomedia of propodeum about as long as wide to about 1.3 times longer than wide; areas of propodeum smooth and shining between strong punctures. Portion of ovipositor that protrudes from metasoma 0.7–0.85 (0.8) 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 to 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 wide, scape excised at an angle of about 50°.
Mesosoma Pronotum with epomia weak to absent; mesoscutum with notauli absent to barely visible; mesopleuron with sternaulus weakly to distinctly 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 strongly coriaceous between punctures. Wings slightly tinged, radial cell along anterior margin of wing 1.0– 1.15 times as long as stigma, areolet 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 1.6–2.0 times as long as second tergite, second tergite 1.5–1.8 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 weak longitudinal striae. Ovipositor weakly down-curved, laterally compressed, with subapical notch; male clasper bluntly rounded.
Colouration of female
Head black, face including clypeus and mandibles orange to yellow, usually orange along outer eye margin; antenna black or dark brown, lighter towards base. Mesosoma including scutellum and most of propodeum orange, mesoscutum black, propodeum usually with black marks anterodorsally; legs orange, hind tibia apically and hind tarsi often brown; forewing with stigma often lighter in anterior half. Metasoma orange.
Colouration of male
As in female.
