Diagnosis. Rhagoletis batava is similar to R. bagheera and R. merzi in general appearance and in having black femora, differing from R. bagheera by its larger size (wing length = or> 3 mm in R. batava vs. <2.5 mm in R. bagheera) and from R. merzi by the conspicuously longer posterior lobe of the lateral surstylus (1.3 times as long as surstylus basal of prensisetae (fig. 4, d) vs. only 0.6–0.7 times as long as surstylus basal of prensisetae in R. merzi (fig. 8, b)) in the male and by spermatheca size and shape in the female (oval, 0.03 mm in diameter, and with the neck as long as the spermatheca in R. batava (fig. 4, i) vs. spherical, 0.09 mm in diameter, with the neck at most 0.8 times as long as the spermatheca itself in R. merzi (figs 2, f; 8 f)), as well as by the different host plants.
Measurements. Body length ♂ = 3.64 mm; body length ♀ = 3.9 mm; wing length ♂ = 3.0–3.6 (m = 3.38) mm; wing length ♀ = 3.3–4.2 (m = 3.8); costal cell length = 0.9; aculeus length = 0.78 mm; aculeus length /costal cell length = 0.9.
Host plant. Hippophae rhamnoides L. (Elaeagnaceae) (Kandybina, 1962).
Distribution. Europe (Korneyev et al., 2018 b); south of West and East Siberia; Middle Asia.
