Wattebledia siamensis Möllendorff, 1902: 160. Type locality: “Siam”.

Wattebledia siamensis : Brandt 1974: 64-65, pl. 5, figs 78, 79.

Material examined.

ZRC.MOL.016325

Distribution and habitat.

Found among floating vegetation along the banks of the Tonle Sap River (locality no. 44).

Remarks.

This is the first record of the species in Cambodia, and the species is known throughout Thailand ( Brandt 1974). It could probably be more widespread along with the larger congeneric species, Wattebledia crosseana (Wattebled, 1886), which has previously been recorded from Cambodia ( Brandt 1974).
