Antenna dark yellow; first flagellomere dark yellow, subtriangular, as long as wide; arista dorsal, dark brown, very short pubescent, with basal segment rather short ( Figure 2B View Figure 2 ). Proboscis brown with black hairs; palpus dark yellow with black hairs and one apical bristle.
Thorax yellow, with pale grey pollinosity; mesonotum metallic green with wide anterior and lateral portions dark yellow; scutellum dark yellow, with basal middle portion metallic green; pteropleuron with a black spot on antero-upper corner; laterotergite with brown anterior margin.
