Genus Parathelphusa H. Milne Edwards, 1853

Type species. Parathelphusa tridentata H. Milne Edwards, 1853 .

Remarks. This large genus of 49 recognised species ( Ng et al., 2008, 2016; Ng, 2014; De Grave et al., 2022) is recorded from southern Thailand to Sumatra, Peninsular Malaysia, Java, Borneo, Sulawesi, as well as Palawan and some adjacent islands in the Philippines. Borneo is not the centre of distribution with just 10 species, but is believed to be the origin of the remaining taxa (cf. Klaus et al., 2013).
