Face, frons, gena, clypeus, mesosoma, dorsal area of hind coxa and basal area of tergites usually black, but more or less yellow in some specimens (face yellow though black medially in the lectotype of J. tamanukii ). Fore wing with a black marking on apical margin ( Fig. 11 ).

♂ (n=11). Similar to females except as follows. Body length: 11.0– 14.5 mm (13.0 mm in the lectotype of J. yamatonis ). Clypeus 0.5–0.6 × as long as wide. OOL/OD = 1.1–1.4. POL/OD = 1.1–1.6.
