Material. Holotype, NHMD 1183713 , ♁, №14, 24–1–1963; Chalcidoidea; B. V. Henningsen; Danish amber, late Eocene (deposited in NHMD). The inclusion is in a reddish, not very transparent parallelepiped piece of amber (ca. 9 × 5 × 3 mm). It is well preserved, but the ventral side of its gaster is obscured by an air bubble ( Figs 1B View FIGURE 1 , 4A, B View FIGURE 4 ).

Syninclusions: absent.

Etymology. The new species is named in honor of our friend, hymenopterist Dr. Sergej A. Belokobylskij.

Description. Male. Habitus as in Figs 1A, B View FIGURE 1 ; 3A View FIGURE 3 . Body length 1.25 mm.

Coloration. Body dark, unicolourous although its true color not determinable because it is completely covered with a thin, shiny layer of air, antennae unicolourous, dark; tegula black; wings hyaline, venation brown, forewings with small darkened area below marginal vein.

Sculpture. Head, pronotum, mesoscutum, scutellum and axillae relatively similarly reticulate, without piliferous punctures; scape, pedicel, tegula, and legs also relatively similarly but finely reticulate; sculpture of face, interantennal prominence as in Figs 2A, B View FIGURE 2 .

Head. Slightly wider than mesosoma in dorsal view; occipital margin rounded ( Fig. 2D View FIGURE 2 ); frontovertex broadly rounded in frontal view, about as long as broad, slightly vaulted above eyes ( Fig. 2B View FIGURE 2 ); eyes bare, without visible setae, with inner orbits ventrally strongly divergent ( Figs 2A, B View FIGURE 2 ); ocelli forming equilateral triangle, posterior ocelli closer to eye than occipital margin; OOL shorter than posterior ocellar diameter; OOL:POL:LOL about 1:4:4; eye reaching occipital margin ( Figs 1A View FIGURE 1 , 3 View FIGURE 3 ); antennal scrobes distinctly carinate, as in Fig. 2A View FIGURE 2 , meeting dorsally, not extended to anterior ocellus, interantennal prominence as in Fig. 4 View FIGURE 4 , dorsally rounded; antennal toruli located in middle between level of lower eye margin and mouth margin ( Figs 2A, B View FIGURE 2 ); distance between toruli equal to distance between torulus and eye, about 2× width of torulus and about 0.5× length of malar space; malar space with complete malar sulcus ( Fig. 2A View FIGURE 2 ), about as long as eye height; clypeus poorly emarginate, with short lateral margins; mandible apparently either 3-dentate or with 2 teeth and truncation of upper tooth ( Figs 2A, B View FIGURE 2 ).

Antenna. Geniculate, with one anellus, 6 funicular segments, and entire clava; radicle short, about 2× as long as broad ( Fig. 2B View FIGURE 2 ), rest of scape ~5× as long as broad, slightly flattened; pedicel as long as first three funicular segments combined, longer than any funicular segments; F1 broader than long, F2–F5 almost quadrate, F6 slightly broader than long; width of flagellomeres gradually increases toward apex; all segments of funicle, at least F2–F6, and basal part of clava with multiporous plate sensilla; clava as long as F4–F6 combined, with small oblique truncation at apex ( Figs 2 A–D View FIGURE 2 ), slightly wider than F6; setae on pedicel and flagellum shorter than diameter of segments, oblique apical truncation of clava with longer and denser pubescence.

Mesosoma. Pronotum short in dorsal view, not conspicuously narrower than mesoscutum, almost vertical in lateral view, with posterior edge emarginate ( Fig. 3A View FIGURE 3 ); mesoscutum broader than long in dorsal view; mesothoracic spiracle open, not concealed beneath pronotum ( Fig. 2D View FIGURE 2 ); axillae meeting; scutellum as long as mesoscutum, without long setae at own apex ( Fig. 3A View FIGURE 3 ); propodeum short.

Wings. Fully developed. Fore wing ~2.2× as long as broad; linea calva without filum spinosum, line of covering setae alongside basal margin of dorsal surface poorly developed ( Fig. 3B View FIGURE 3 ); parastigma only slightly wider than rest of submarginal vein, hyaline break present; marginal vein as long as broad, widened, 2× as broad as postmarginal vein; stigmal vein 2.4× as long as marginal, with widened stigma, and with long narrow uncus consisting row of 3 sensilla ( Fig. 3B View FIGURE 3 ); postmarginal vein 2.6× as long as marginal vein, longer than stigmal vein ( Figs 3A, B View FIGURE 3 ); enlarged seta marking apex of postmarginal vein of forewing absent (as long as others on that vein); fringe setae short. Hind wing relatively wide; membrane of costal cell along marginal vein without line of long setae.

Legs. Normal in size, mesotibial spur about as long as mesobasitarsus or only slightly shorter, both relatively long; tarsi 5-segmented.

Metasoma. Shorter than mesosoma; cerci in apical third of metasoma, with long setae ( Figs 1B View FIGURE 1 , 4 View FIGURE 4 : cers); apical tergum longer than other terga; genitalia as in Fig. 4 View FIGURE 4 , digitus with 3 small teeth.

Female. Unknown.
