Remarks. The specimen from Thailand agrees well with the description given by Wiles (1991) for the male specimens from the Selangor, Malaysia. According to Wiles (1997), N. bahtilli might be a male of N. malayensis with well developed palp projections, but no intermediate specimens have been found. No female has yet been described.

Distribution. Peninsular Malaysia. New for Thailand.
