Type material.

Holotype of Opius longurius , ♀ (FAFU), "[China:] Fujian, Wuyi Mt., Sangang, 30.vi.1988, Zhang Xia-bin". Holotype of Opius vacuus , ♀ (ZISP), "[Russia], Primorskij kraj, Spassk, les, poljany, 19.viii.1991, Belokobylskij", " Opius vacuus sp. n., det. Tobias ‘95”, "Holotypus Opius vacuus Tobias". Paratype of Opius mediocarinatus . ♀ (MTMA) from Japan (Honshu: Kamikochi) examined.

Comparative diagnosis.

The combination of lacking the medio-posterior depression of the mesoscutum (Fig. 103) and the slender first metasomal tergite with a long median carina (Fig. 104) makes this species easy to separate from all other species of Rhogadopsis in China.

Distribution.

China (Fujian (as longurius ), Hunan (as longuria ), *Shaanxi), Russia Far East, Japan, Korea. The record from Spain ( Avinent and Jiménez 1987) needs reconfirmation.

Biology.

Unknown.

Notes.

The inclusion of Opius mediocarinatus Fischer from Japan in Psyttalia by Tobias (1998, 2000) is an obvious misfit; it is also excluded by Wharton (2009). It has a short (hardly protruding) ovipositor (Fig. 100), vein m-cu of fore wing 0.65 times as long as vein 1-M, vein m-cu of fore wing angled with vein 2-CU1, and a normal second tergite and hypopygium. It belongs to the genus Rhogadopsis Brèthes, 1913, as defined by Li et al. (2013) and is one of the easier identifiable species of the genus because of the shape and sculpture of the first tergite.

The holotype of Opius vacuus is a very typical Rhogadopsis mediocarinata because of the reduced posterior groove of the pronotal side, the striped mesoscutum and the elongate first metasomal tergite with the distinct median carina. Vein 1r-m of the hind wing is rather short (0.55 times as long as vein 1-M), but obviously this vein is rather variable in this species and vein 1-M of hind wing has a weak bend subapically.
