Figs 1–10  
 Type material. Holotype ♀, Indonesia, West Papua, Arfak Mts, Duebei env[irons], 20 km S Warmere, 1190 m, Manokwari dist., 21.I.–8.II.2009, S. Jákl [OLL]. Paratypes: 3 ♀ with same label as holotype; 1 ♀, same place and collector, 21.I.–28.II.2008 [OLL].   
 Diagnosis. Female. The female of this new species can be distinguished from those of other congeners by the following characters: (1) propodeum without median sulcus dorsally; (2) fore wing fusco-hyaline, with subbasal yellowish fascia and subapical whitish fascia located beyond third submarginal cell (Fig. 8); (3) antennae black, with scape ventral face brown; (4) mesoscutellum black, with small median yellow spot (Fig. 9). Male. Unknown.   
 Description. Female. Length: body 11.5–15.6 mm; forewing 10.7–13.4 mm. Head width 1.0–1.1 times its height (from apical margin of clypeus to vertex); MID 0.5–0.6 times head width in frontal view. Ocelli large, not raised above level of frons; ocellar triangle right-angled; POD: OOD = 0.8–1.0 (Fig. 4). Head in frontal view with vertex noticeably produced above dorsal eye margin (Fig. 5). Posterior margin of vertex in dorsal view straight (Fig. 4). Head in lateral view with frons convex, especially in its lower part (Fig. 3). Temple in dorsal view not developed (Fig. 4). Gena in profile strongly narrowing toward occiput (Fig. 3). Malar space slightly developed. Clypeus barely convex, its width 3.05–3.4 times its height, and 1.0–1.1 times LID; anterior margin straight; anterolateral corner rounded. Labrum broad and well-exposed, its apical margin roundly emarginate medially (Fig. 5). Mandible slender, with small subapical inner tooth. Antenna (Fig. 3) with scape normal shaped and flagellomeres cylindrical. Ratio of scape, pedicel and flagellomeres length (on longest side, in holotype) 38: 12: 41: 43: 41: 41: 37: 35: 30: 30: 27: 29. Scape length 0.73–0.75 times UID. F1 length 3.0–3.7 times its maximum width (in dorsal view), and 0.65–0.8 times UID; apical flagellomere pointed apically.   
 Mesosoma. Anterior face of pronotum in lateral view not differentiated from dorsum, roundly merging into dorsum. Posterior margin of pronotum rounded and indistinctly subangulate medially (Fig. 4). Pronotum length (without collare) 0.58–0.65 times mesoscutum length in dorsal view medially. Dorsum of mesoscutum almost flat. Dorsum of mesoscutellum more convex than that of metanotum. Metapostnotum weakly depressed, barely emarginated postero-medially, its length 0.36–0.5 times metanotum length medially. Dorsum of propodeum in lateral view weakly convex and roundly merging into its obliquely truncate posterior face.   
 Legs. Profemur very stout in lateral view (Fig. 3). Protarsomere 1 ventrally with longitudinal carina possessing row of dense and short spines. Mesotibia with view short spines dorsally. Mesotarsomere 1 with row of short spines ventrally. Metatibia with three rows of short spines dorsally. Metatarsomere 1 with scattered spines. Metatarsomeres 2 and 3 with spines ventrally. Metatibia longer spur length 0.45–0.55 times metatarsomere 1 length. Tarsal claws of all legs symmetrical, with acute inner tooth.   
 Wings. Fore wing (Fig. 8) fusco-hyaline, with two fasciae: subbasal yellowish and subapical whitish located beyond third submarginal cell. Pterostigma dark brown. Second submarginal cell length 1.6–1.9 times its maximum height, narrowed on vein Rs by 0.84–1.0 times its own length on vein M, receiving crossvein 1m-cu at basal 0.55–0.63. Third submarginal cell length 1.8–2.4 times its maximum height, narrowed on vein Rs by 0.4–0.5 times its own length on vein M, receiving crossvein 2m-cu at basal 0.38–0.45. Crossvein 2rs-m straight. Crossvein 3rs-m arched. Crossvein cu-a originating just beyond separation of vein M+CuA. Vein M not touching wing margin. Hind wing (Fig. 7) translucent, with slightly brownish apical portion; crossvein cu-a evenly arched and hardly anterofurcal.   
 Sculpture and pubescence. Antenna, head, meso-, metasoma, and legs matt. Body with inconspicuous microsculpture. Mandible smooth apically. Metapostnotum with fine transverse striae. Frons and vertex with dense short erect pale setae. Gena, pronotum, mesoscutum, mesoscutellum, metanotum, meso- and metacoxae with scattered short erect pale setae. Clypeus and propleuron with few very long erect pale setae. Propodeum postero-laterally with scattered short gray setae. S1–S6 and T6 with erect pale setae. Body with fine pale pubescence. Propodeum with gray pubescence posteriorly. T1–T3 along posterior margin laterally with transverse spots of somewhat silver pubescence.   
 Colour. Body black (Figs 1, 2), with following ferruginous-red: scape basally; apical half of clypeus; labrum; mandible medially; profemur extreme apical portion; protibia inner surface; protarsi; mesofemur baso-dorsally; mesotibia mostly; mesotarsomeres 1–3; sometimes metatibia outer face. Lower frons along inner orbits with small yellow spots. Collare more or less yellowish. Pronotum along posterior margin with transverse yellowish stripe, sometimes weak. Mesoscutellum with small median yellow spot, sometimes indistinct. Metatibia dorso-basally with yellow spot. Meso- and metatibia spurs yellowish. Claws dark brown.   
 Male. Unknown.   
 Distribution. Indonesia (West Papua Prov.).   
 Etymology. The new species is named in honor of Kirill Glebovich Mikhailov (Moscow, Russia), a founder of the “Russian Entomological Journal”, on the occasion of his 60th birthday.
