This species gets its name from its rufous pronotum, which looks like a collar.
Forewing length 4.1 mm in female holotype, 2.9 mm in male paratype. Antenna of female broken, in male with 26 flagellomeres. 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 the diameter of the ocellus. Mesoscutum 0.85–1.0 times as long as wide. Mesopleuron smooth and shining between strong punctures and with a large impunctate area around speculum. Area superomedia of propodeum about as long as wide in female, longer than wide in male; areas of propodeum smooth and shining between strong punctures. Portion of ovipositor that protrudes from metasoma 0.75 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 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 indistinct; mesoscutum with notauli barely indicated; mesopleuron with sternaulus only weakly 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 1.0 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 1.7 times as long as second tergite, second tergite 1.6 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 the very 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 towards tip, laterally compressed, with a subapical notch; male clasper narrowly rounded.
Colouration of female
Head black, face including clypeus and mandibles orange to yellow, orange along outer eye margin; antenna black or dark brown, lighter brown to orange towards base. Mesosoma including scutellum black, pronotum and propleurae orange; legs orange, hind coxa darkened at base; forewing with stigma often lighter in anterior half. Metasoma dark brown with a broad orange band basally on tergite 3 and narrow, yellow bands apically on all tergites.
Colouration of male
As in female, but pronotum only orange anteriorly.
