Type species: Rhynchopsilus apertus Kieffer, 1908. Synonymised by Macek, 1995.	en	Rechnitzer, George (2021): Review of the genus Opazon Haliday, 1857 (Hymenoptera: Diapriidae: Belytinae) in the fauna of Russia. Russian Entomological Journal 30 (1): 78-83, DOI: 10.15298/rusentj.30.1.09, URL: http://dx.doi.org/10.15298/rusentj.30.1.09
03AB87E0FF9C9733B3429C34D788FE03.taxon	diagnosis	DIAGNOSIS. Small parasitoids (1.7 – 3.0 mm); pale brown to black. Head in frontal view with genae converging towards mouthparts; mouthparts hypognathous; mandibles beak-like, bidentate; clypeus strongly convex, higher than its width; labrum triangular; tentorial pits situated in deep depression; antennal shelf prominent, toruli close to each other. Female antenna 15 - segmented, incrassate apically; male antenna 14 - segmented with cylindrical antennomers and A 3 mostly modified. Mesosoma usually a little higher than wide; pronotum with prominent pronotal shoulders, with sharp and distinct epomia; pronotal pits absent, epomia not interrupted; pronotal collar sculptured, often with distinct transversal keel; mesonotum convex with complete and deep notauli; propodeum slightly transverse with simple median keel; plicae distinct throughout and weakly projecting posteriorly. Venation with radial cell closed or partly open apically (Figs 14 – 15); veins C, Sc, marginal, postmarginal, stigmal, radial and basal veins tubular; marginal vein longer than radial cell and distance from marginal vein to basal vein. Petiole subcylindrical, a little longer than wide, finely sculptured; T 2 with five deep and short grooves at base; S 2 without any prominences anteriorly; female metasoma fusiform, compressed at posterior third, with pygidium extended and down curved; hypopygium enlarged, surmounting epipygium at sides; ovipositor long, as long as metasoma without petiole; gonapophyses slender. RELATIONSHIPS. The genus Opazon belongs to Pantolytina subtribes and closely related to the genus Pantolyta Foerster, 1856, differing from it mainly by distinctly beak-like shape of mandibles. Moreover, the male genitalia of Opazon have apex of volsella fused with digitus, in difference from Pantolyta where volsella is free.	en	Rechnitzer, George (2021): Review of the genus Opazon Haliday, 1857 (Hymenoptera: Diapriidae: Belytinae) in the fauna of Russia.

03AB87E0FF9C9733B3429C34D788FE03.taxon	discussion	REMARK. Some difficulties in separation of O. parvulum and O. frigidum females are present. The females both species can be recognized in the Western Palaearctic fauna (Europe and west of the European part of Russia) using the key suggested by Macek [1995], but in the Eastern fauna (center and east of the European part of Russia, Ural, Siberia and Far East) the species better determinate by using characters described in the key above.	en	Rechnitzer, George (2021): Review of the genus Opazon Haliday, 1857 (Hymenoptera: Diapriidae: Belytinae) in the fauna of Russia.
