Differential diagnosis. This new subspecies clearly differs from the other subspecies with the following unique features: pronotum wider than in other subspecies; unique blue to green colour scally patches on body; according on available data, subspecies distribution restricted to Babuyan Island; eyes smaller, not convex from outline of the head.

Etymology. This new subspecies is named after Babuyan Island which is original site where this subspecies is distributed and abundant.
