Diagnosis. This species differs from the other species in the bitaeniatus group by its more slender body shape, lighter coloration, a thinner yellow longitudinal band along the body and which is underlined ventrally by a narrow black line, and strong M-shaped sclerotization of ectophallic fold in male genitalia ( Robillard & Tan, 2013).

Habitat. The species lives in shrubs, grasses, at low to average elevations (50–100 m) in open secondary habitats.
