Remarks and distribution. Since its original description by Ohaus (1900), Parastasia kraatzi had only been recorded from Sumatra Island. However, this study surprisingly reports its presence on the Asian mainland for the first time, at a location remarkably distant from the type locality. In fact, the species appears to have a much wider distribution across the Indochinese region than previously recognized. Additionally, a fresh male specimen was collected in a white rotting log, while the other one was caught by a light trap.
