Remarks

This species will key close to D. (R.) jagannathi Dash and Viraktamath in the key of Dash and Viraktamath (1998). It resembles D. (R.) jagannathi in having a slender, elongated aedeagal shaft but differs distinctly in not having a bisinuated aedeagal shaft, and in the shape of the apophyses of styles. This species is named delongi in the honour of Dwight Moore Delong, a renowned leafhopper taxonomist.
