Conspecificity. Stuart et al. (2010), Nishikawa et al. (2013a) and Nishikawa et al. (2015) point out that only a single, unvouchered sample of T. verrucosus was included, and cautiously defended the need for further examinations before taxonomic conclusions.Khatiwada et al.

The new species formed a unique clade within an unresolved polytomy containing T. verrucosus, T. shanjing, and T. pulcherrimus.Phimmachak et al.

The authors referred to this population as T. verrucosus from Laos, which formed a clade with T. shanjing, T. pulcherrimus, and T. verrucosus from the type locality.Phimmachak et al.
