Remarks. Thach (2016) mentioned this species from southern Vietnam (Ninh Hoa District, Khanh Hoa Province), far from all other known localities in the Malay Peninsula, Myanmar (Tavoy and Tenasserim) and Thailand ( Tumpeesuwan & Panha, 2008). This species seems to have the largest range in the entire genus.

Two samples ( SMF 262529 = “ holotype ” and SMF 262530 = “ paratypes ”) found in the SMF were labelled as “ Schistoloma siamensis Brandt” with the following locality data: “ Thailand: an den Tanto-Fällen bei Ban Nong Star; Yala Provinz, leg. Brandt, 18-7-1964, No. 1968/1”. However, the name “ Schistoloma siamensis ” was never published, and is not available .
