New locality data: 1 ♂, ZFMK MYR6262 About ZFMK , Nakhon Ratchasima Province, Pak Ching District, near Highway 3052, 14°30'59.2''N, 101°23'52.9''E, 10.VI.2017 GoogleMaps ; 1 ♂, 2 ♀♀, ZFMK MYR6779 About ZFMK , same data as previous GoogleMaps ; 1 ♂, ZFMK MYR7236 About ZFMK , same data as previous GoogleMaps ; 2 ♀♀, NHMD K53, Nakhon Nayok Province, Khao Yai National Park , 700 m, leg. 29.IX–6.X.1984, leg. Karsholt, Lomholdt & Nielsen.

Remarks. Both localities lie close to the type locality ( Fig. 2A View FIGURE 2 ). However, specimens from both localities differ significantly genetically and might represent two different species.
