Gorochov, M. Berezin, I. Kamskov, E. Tkatsheva ( ZIN). Paratype – 1 ♀ , same data as for holotype ( ZIN) .

DESCRIPTION. Female (holotype). Coloration and structure of body similar to those of

Rh. uniformis but with following differences: yellowish stripes on pronotal disc with slightly darker (intensively yellow to almost orange) inner halves; dorsal tegminal field light brown with somewhat darker (brown) proximal half; light brown stripe along rest part of anal tegminal edge also slightly more distinct than in Rh. uniformis (for comparison see Figs 69

and 75); apex of upper rostral tubercle somewhat narrower and almost angular in dorsal view

( Fig. 75 ); spine of fore coxa about 0.25 mm in length; exposed parts of hind wings, visible behind tegminal apices, almost 1 mm in length; genital plate different, i.e. clearly longer and with narrow and moderately deep posteromedin notch ( Fig. 59 ); ovipositor ( Fig. 76 ) similar to that of Rh. uniformis (its apex also almost as in Fig. 63 ).

Variations. Second female with apex of upper rostral tubercle barely more rounded, and exposed parts of hind wings, visible behind tegminal apices, almost 0.6 mm in length.

same body parts with left fore leg from side/above, male (70). Male abdominal apex from above (71), from below (72) and from side (73). Ovipositor from side (74, 76, 78, 80, 81, 83,

85–87); sixth and seventh abdominal sternites as well as genital plate from below, female (88).

Male unknown.

MEASUREMENTS. Length (in mm). Body 10.5–11; body with wings 19–21; pronotum

3.3–3.5; tegmina 15.5–17; hind femora 8–8.5; ovipositor 4.2–4.6.
