TYPE MATERIAL. Holotype – ♀, Myanmar, Mandalay Region, 2 km south of town Popa (68 km west of Meiktila), 20º54'45''N 95º12'31''E, Mt. Popa , 700 m, 6.XI 2022, leg. A. Kim [ IBSS].

DIAGNOSIS. FEMALE. Genal carina strong, forming tooth at hypostomal carina and extending posteriorly to occipital carina where distinctly angulate. Hypostomal bridge medially widened with projection. Head and metasoma black, mesosoma ferruginous-red. T 1 dorsally with medial small spot of golden setae. T 2 in basal half with two pale spots located transversely and apicolateral spot of golden setae. T 3 with widely interrupted band of golden setae. MALE. Unknown.

DESCRIPTION. FEMALE. Body length 12.1 mm. Colouration and setation. Head and metasoma black, mesosoma ferruginous-red. Head with sparse whitish setae mixed on frons, occiput and genae with sparse sub-erect black setae. Legs black, palps pale brown. Body setae generally sparse and black, except posterior propodeal face and anterior face of T 1 with long dense erect whitish setae; frons, vertex, and mesosomal dorsum laterally with short sparse sub-erect black setae. Mesopleural vertical carina with long erect whitish setae. Legs, especially meso- and metatibia with long dense recumbent yellowish setae. T 1 dorsally with medial small spot of golden setae, laterad of it with dense recumbent black setae. T 2 in basal half with two spots of golden setae located transversely, dictance between spots equal its diameter, posterolaterally with spot of golden setae. T 3 with widely interrupted band of golden setae. T 6 except pygidial plate with whitish setae. S2–5 with sparse sub-erect long golden setae, S2 and S3 apically with fringe of dense golden setae, S6 with dense golden setae oriented backward.

Head. Width behind eye 0.86 × humeral mesosomal width. Frons, vertex, and gena with large confluent punctures. Mandible with dorsal carina extending from base to apex, apex unidentate. Clypeus apically not dentate, basomedial portion coarsely sculptured.. Antennal scrobe with arcuate lateral carina. Genal carina strong, forming large tooth at hypostomal carina and extending posteriorly to occipital carina where distinctly angulate. Hypostomal bridge medially widened with projection. F1 1.25 × F2 and 2.0 × pedicel length, F2 1.8 × pedicel length.

Mesosoma. Length 1.3 × maximum width. Dorsum of mesosoma with large coarse punctures; mesopleuron convex, punctured, vertical carina ending dorsally to strong tooth. Humeral carina well developed with oblique carina posterad. Ratio of width of humeral angle, anterior spiracle, lateral mesonotal tooth, propodeal spiracle, and posterolateral propodeal angle 90:95:110:95:80. Scutellar scale lacking. Posterior propodeal face abrupt, lateral propodeal face with shallow sparse punctures.

Metasoma. T 1 broad with distinct anterior and dorsal faces, dorsally with small dense punctures. T 2 with large coarse punctures, posteromedially with small dense ones. T 4–5 and S3–5 with small dense punctures. S1 with simple longitudinal lamella. S2 with dense large punctures. T 2 anterolaterally with deep elongated pubescent fovea. T 6 basally and laterally coarsely punctate, setose, apical half with medial part without setae, pygidial plate not carinated laterad even apically, considerably convergent basally, with weak transverse striae.

MALE unknown.

REMARKS. A female of new species (male unknown) is strikingly differs from congeners by having two golden spots located transversely in basal half of T2 (lacking such spots or having 1(3) spots in other species of the genus) and much resembles the females of Trogaspidiini species. Possibly this species may be the opposite sex of the male Odontomutilla miranda (Smith, 1855) described from Northwestern India, which also has an unique character among the male species of the genus: T2 with two pale spots located transversely near the middle .

NATURAL HISTORY. The wasp was found near the top of the temple complex of Mount Popa, 700 m altitude, on the concrete fence of the viewing platform ( Fig. 6 ).

ETYMOLOGY. The specific name is dedicated to Nikolai Alexandrovich Listopadov, the author of two splendid books about the Buddha's lands: “На ЗемлЯх Будды” (In the lands of the Buddha, 2006) and “По стопам Будды” (In the footsteps of the Buddha, 2005).
