Diagnosis. Among the species with gena and vertex smooth, the posterior rim of metasoma not overhanging the posterior margin of metasoma, the propodeal spiracle surrounded by well-developed cristula which delimits a smooth, polished area, and T1 and T2 at least partially black, Buluka petrjanstai can be distinguished by having T1 partially yellow and T2 almost entirely yellow, with the yellow covering the full width of the tergite except for a black margin on the anterior 0.1. Other species have either T1 and T2 entirely yellow ( B. townesi , B. noyesi , and B. vuquangensis ), completely black ( B. achterbergi ), or T1 and T2 only partially yellow, with the yellow not covering the full width of the tergite (e.g., B. taiwanensis and B. buntikae sp. nov.).

Head in anterior view 0.9× as long as wide medially, setose; first flagellomere as long as second flagellomere, 4.2× as long as wide; second flagellomere 4.2× as long as wide; fifteenth flagellomere 2.0× as long as wide; face smooth, densely setose ventrally; frons setose; vertex smooth; gena smooth, sparsely setose; eyes setose, diverging behind antennal sockets; clypeus almost straight to slightly concave, smooth and densely setose; ratio of maximum head width to minimum face width 2.30 (74/32).

Mesosoma 1.44× as long as high; mesoscutum punctate crenulate anteriorly and laterally; notaular courses, posterior and lateral margin of mesoscutum reticulate, setose; scutellar sulcus with 10 medial carinae; scutellum reticulate rugose with strong setae; propodeum with medial carina, finely reticulate rugose, glabrous; propodeal spiracle surrounded by cristulae; area around propodeal spiracle large, polished but not reaching anteriorly to fore margin of propodeum; pronotum smooth posteriorly; mesopleuron mostly punctate crenulate (reticulate) and setose, smooth and glabrous anteriorly; metapleuron smooth and glabrous antero-medially, posterior part punctate reticulate.

Metasoma. Posterior rim of metasoma shorter than carapace; T1 with crenulate median longitudinal groove with smooth polished area in basal medial half; T1 0.6× as long as wide apically, reticulate rugose in lateral parts of its basal half, areolate in apical half; T2 0.4× as long as wide apically, all covered with longitudinal striae; second metasomal suture shallow and crenulated; T3 with narrow longitudinal groove smooth basally, punctate apically, longitudinally striate in basal half, reticulate and punctulate apically; ovipositor sheaths with two spatulate sensillae apically.

Legs. Metacoxa large, setose dorsally and ventrally, reticulate, with distinct transversal striae apically; metafemur 3.5× as long as wide; metatibia 4.16× as long as wide; inner metatibial spur 0.6× as long as basitarsus; metatarsal claws with one tooth.

Wings. Fore wing 3.25× as long as wide; fore wing apically and in apical 0.2 of basal and subbasal cells setose, basally glabrous; basal, subbasal, 1 st discal and 1 st subdiscal cell glabrous; pterostigma 3.45× as long as wide; 2RS vein of fore wing less than 2× as long as r-m vein.

Body measurements. Body length: 2.5 mm; fore wing length: 2.7 mm; second flagellomere length/width: 4.2; fifteenth antennal segment length/width: 2.0; metafemur length/width: 3.5; metatibia length 1.1 mm; carapace length/width: 1.9; T1 length/apical width: 0.6; T2 length/ apical width: 0.4.

Color. Head orange to dark brown; face orange; apex of clypeus, malar space, frons, vertex and temples dark brown to black near occipital carina; palpi white-yellow; mesosoma black; fore and middle legs yellow with tarsal segments 1–4 whitish; metacoxa, metatrochanter, metatrochantellus and metafemora black; metatibia black with apical 0.3 white-yellow; hind basitarsus black; hind tarsal segments 2–4 white-yellow; hind telotarsus brown; tegula light brown; wing venation light brown; fore wing infuscate throughout below pterostigma and around vein 1-CU; T 1 in basal half with oval light yellow area around medial longitudinal groove; T2 almost fully light yellow except for 0.1× in anterior margin which is black; T3 black; ovipositor sheath dark brown to black.
