Genus Parathelphusa H. Milne Edwards, 1853 View in CoL

Parathelphusa H. Milne Edwards, 1853 View in CoL ( type species Parathelphusa tridentata H. Milne Edwards, 1853 View in CoL , subsequent designation by Rathbun, 1905; gender feminine)

Parathelphusa ( Mesotelphusa) Roux, 1915 ( type species Telphusa celebensis De Man, 1892 , by original designation; gender feminine)

Palawanthelphusa Bott, 1969 ( type species Potamon ( Parathelphusa) tridentata var. pulcherrima De Man, 1902 , by original designation; gender feminine)

Remarks. With the new species described here, Parathelphusa H. Milne Edwards, 1853 , currently contains 48 species from southern Thailand, Peninsular Malaysia, Singapore, Sumatra, Brunei, Kalimantan, Java, Sulawesi and Palawan (updated from Ng et al. 2008) ( Table 1). Parathelphusa ( Mesotelphusa) Roux, 1915 ( type species Telphusa celebensis De Man, 1892 ) is a junior synonym of Parathelphusa , and the only difference is in the form of the anterolateral margin, which is not reliable as a generic character (see Chia & Ng 2006). Bott (1969, 1970) also recognised Palawanthelphusa Bott, 1969 ( type species Potamon ( Parathelphusa) tridentata var. pulcherrima De Man, 1902 ) but the only diagnostic character is the form of the G1, which has also shown not to be reliable (see Ng & Goh 1987). It is also a subjective junior synonym of Parathelphusa .

A recent phylogeographic study of Parathelphusa by Klaus et al. (2013) showed that specimens of P. oxygona from Sarawak belonged to a distinct lineage. It also showed that the species diversity in Borneo is higher than what is known at present, with various un-named clades of Parathelphusa . This agrees with unpublished data that indicate that there are at least half a dozen new species from Borneo still awaiting description.
