Habitat. We found this species from Khao Krajom in Suan Phueng District, Ratchaburi Province. This area is an important non-protected area of the Tenasserim mountain range. Grasshoppers were found perched and fed on Alpinia malaccensis ( Zingiberaceae ) and some grass species in both understory and open area of lower montane forest in daytime.

Distribution. This species is known from type locality only.

Etymology. The specific epithet from the Latin word “punctatus (-a, -um)” which gave the meaning “punctuated” for the integument of both sexes distinctly punctuated.
