The nymphs show an abdominal coloration pattern characterized by terga I–VII and X mostly brown (with two big middle light yellow spots in segments IV and V in some specimens), segment VIII with a big triangular light yellow area with its base occupying most of the segment distal margin, and segment IX almost entirely light yellow. Femora show a wide variation in coloration pattern and in thoracic pro and mesonota there are two lateral small yellow spots.

), a wide variation in the color pattern is addressed, most nymphs have “a reduced tergal maculae that are confined near the posterolateral corners”, but a few specimens have “slender and elongated sublateral maculae that extend almost the entire length of the terga” or “abdominal terga faintly washed with brown which obfuscates the pattern of maculae”. Additionally, “pro and mesonota lack spots” and femora shows “basal and apical yellow spots”. Structural characters agree with the original description.
