Remarks.

Scaphula minuta was first described from Songkhla Lake in southern Thailand (Ghosh 1929) and only recently reported to be distributed in southern Vietnam (Bogan and Do 2014). In addition, Bogan and Do (2014) mentioned that past records of ' Scaphula pinna ' in Thailand (i.e., Brandt 1974) should be referred to as Scaphula minuta . Based on Bogan and Do (2014), the species previously identified as Scaphula pinna and cited as being uncertain in Cambodia (Madhyastha 2012) was probably Scaphula minuta . However, the distinction between these two species is pending systematic revision, and our records represent the first confirmation of Scaphula minuta in Cambodia.
