Type species. Rovnopositor voblenkoi Simutnik, sp. nov. Species composition. Type species only. Etymology. The name of the genus is a combination of the words "Rovno" and "ovipositor" . The new genus is distinguished by an unusual ovipositor structure. Gender masculine. Diagnosis. Habitus not 'encyrtiform' , body not compact, not flattened; ocelli in almost right angled triangle (Fig. 5B ), posterior ocelli elliptical in dorsal view; frontovertex about as long as broad; flagellum long, first funicular segment 1.5 x as long as broad, funicle without transverse segments; clava slightly longer than F4-F6 combined, 2.5 x as long as broad; mesoscutum and scutellum convex, notauli absent; scutellum as broad as long, and as long as mesoscutum; marginal vein relatively short, twice as long as broad, and one-third as long as postmarginal vein; setae along basal margin of linea calva short; filum spinosum absent; parastigma almost not widened; strigil present, well-developed; cerci slightly advanced toward gastral base, with long cercal setae (Fig. 5D : cers); apex of hypopygium reaching way past apex of gaster (in ovipositing position, Fig. 5A,D : hyp), lateral margins of hypopygium bare, without row of setae; protruding part of ovipositor stylet stout, upwardly bent (in ovipositing position); ovipositor sheaths strongly reduced, not visible in lateral view. Remarks. The new genus differs from Archaeocercoides in the right angled ocellar angle; the frontovertex is about as long as broad; its long flagellum, the first funicular segment being longer than broad, the funicle without transverse segments; the clava slightly longer than F4-F6 combined, 2.5 x as long as broad; the relatively short marginal vein, twice as long as broad and one-third length of postmarginal vein; the convex mesoscutum and scutellum; the well-developed strigil; the cerci are noticeably advanced toward the gastral base; the lateral margins of hypopygium are bare; and in its stouter and longer protruding part of the ovipositor stylet (in ovipositing position).
