Moderately large sized, dark reddish brown overall, with bright yellowish to white on most of the head and mesosoma and few markings on metasoma; metasoma black posteriorly; mandible with upper tooth 1.6 × as long as lower tooth; clypeus hardly convex in profile, ventral margin truncate; face subquadrate, 1.1 × as high as wide; antenna short, with 52 flagellomeres; mesopleuron finely transversely striate, metapleuron with somewhat coarser striation; basal transverse carina of propodeum distinct, anterior area of propodeum finely rugose, posterior area foveolate; proximal sclerite weakly sclerotized; fore tibia with three longitudinal rows of dispersed but regularly arranged short spines along outer surface.


From Latin, in reference to its astonishing and splendid appearance and colour.

COLOUR. Dark reddish brown overall, with yellowish white on the following parts: head (except a narrow longitudinal line extending a short distance after fore ocellus to base of clypeus), clypeus, labrum and palpi, posterior margin of head around occipital carina, mandibles (except teeth ferruginous), pronotum (except a small reddish triangular area just above tegula), mesoscutum (except for three reddish brown lobes, of which middle one doesn’t reach posterior margin and lateral ones do not reach anterior margin of mesoscutum), tegula, scutellum, two longitudinal oval patches on postero-lateral part of propodeum, postscutellum, subalar prominence, latero-ventral side of mesopleuron, a small area just above mesocoxa, most of metapleuron (leaving a small upper area reddish brown in colour). Metasoma darker than rest of body, with T2 and T3 above and almost all remaining tergites patterned with yellow, last sternite (subgenital plate) black; legs with coxae, trochanters and femora distinctly darker in colour than rest. Wings hyaline, fore wing with pale brown pterostigma, base of Rs+2r as well as uppermost part of Rs & M and 1A of hind wing pale brown to yellow, otherwise all veins are dark brown to black.

HEAD. Mandible moderately twisted, with upper tooth 1.6 × as long as lower tooth, bare and without groove on outer surface; clypeus smooth, hardly convex to flat in profile, ventral margin truncate; malar space 0.3 × mandibular base; face subquadrate, 1.1 × as high as wide, rather smooth; gena constricted behind eyes; occipital carina complete; ocelli enlarged; antenna with 52 flagellomeres.

MESOSOMA. Pronotum medio-dorsally normal, unspecialized, transversely wrinkled laterally; mesoscutum finely shagreened; epicnemial carina distinct to level of ventral corner of pronotum; postpectal carina distinct only laterally, above bases of mesocoxae, otherwise indistinct; notauli indistinct; scuto-scutellar groove smooth; scutellum nearly smooth, carinate to near apex; mesopleuron finely transversely striate,

metapleuron with somewhat coarser striation; basal transverse carina of propodeum distinct but weak, anterior area of propodeum nearly smooth, posterior area finely foveolate.

WINGS. Proximal sclerite weakly sclerotized; central sclerite totally absent; Rs+2 r slightly   sinuate basally; cu-a subopposite Rs & M by about 0.25 cu-a length; hind wing with 7 distal hamuli on R1.

LEGS. Fore tibia with three longitudinal rows of regularly arranged dispersed short spines along its outer surface; hind coxa elongate; hind tarsal claw with short, widely spaced teeth; outer mid and hind tibial spurs much shorter than inner spurs (0.23 × and 0.25 × respectively).

METASOMA. Metasomal T2 slightly longer than T1, T2 height 0.4 × its length; thyridium distinct, ellipsoid.
