( Figs 3 , 4 )

Material examined.

Additional material: 4 males and 13 females from ZSM collection; 1 male (paratype of R. maiator ) from CMZL collection.

Diagnosis. The female of this species is characterized by the black hind coxae; short, parallel to weakly narrowed temples; strongly sculptured mesoscutum; densely punctate mesopleuron with partly rugulo-punctate speculum ( Fig. 3. 3 ); propodeum with sometimes indistinct costulae distally and area superomedia as wide as area basalis ( Fig. 4 . 9); and ovipositor which is about 1.3–1.7 × the length of hind tibia. The male generally resembles female and has yellow face and partly yellow temples.
