This species is characterized by the presence of the relatively small body, the head and thorax without spots, the brown veins of forewing and hindwing, the male sternum IX slightly elongated and curved upwards dorsal apically, the quadrate median arch of gonarcus concaved at middle of posterior margin, the arcessus swollen at base, and the length of female subgenitale slightly longer than wide.
