Diagnosis. It is a medium sized species (forewing length: 31.6 mm) with dark brown thorax and pleuron, covered with long black setae. It is also characterized by the presence of a broad median longitudinal yellow stripe across pro-, meso- and metanota, a short yellow stripe on the posterolateral margins of mesonotum, and a median yellow stripe on pleuron.
Measurement (♀ n=1). Forewing length: 31.6 mm, width 9.6 mm; hind wing length: 28.4 mm, width 7.5 mm; abdominal length 19.0 mm; body length: 25.3 mm.
