Each ocellus set on yellowish part of vertex. Eyes greenish, prominent, wider than long. Epicranial suture deep yellowish to greenish. Dorsal postclypeal area greenish anteriorly and brownish posteriorly. Scape yellowish and supra-antennal plate yellow with slender brownish interior margin. Antennal flagella and pedicel black.

Dorsal part of tergites 3 to 7 entirely yellowish; lateral part of tergites yellowish with black wide spot getting thinner and progressively fading upwards. Tergite 8 mostly black with the posterior third yellowish. Sternites 1 to 8 entirely yellowish. Timbals with four longs ribs fused ventrally and dorsally; three intercalary short ribs.
