Remarks. Cirolana thailandica has been discussed completely in the original description. The most similar species to C. thailandica is C. siamensis (see remarks on the C. thailandica ). The co-occurrence of both species at a single locality in West Papua indicates that the two species can be sympatric as has been shown in Thailand (Rodcharoen et al. 2016).

Distribution. Thailand (Rodcharoen et al. 2016); range extended now to Singapore and West Papua ( Fig 1 ).
