can be distinguished from all other silurids in possessing the following two synapomorphies: a supralabial fold that is anteriorly truncated such that the lower edge extends far posterior to the base of the maxillary barbel and an elongate antorbital process of the lateral ethmoid that is not anteroposteriorly compressed (Bornbusch, 1995).

also do not show any marked sexual dimorphism in the pectoral-fin spine as reported for most other silurid genera (e.g. Inger &amp; Chin, 1962; Bornbusch &amp; Lundberg, 1989; Ng &amp; Ng, 1998). The two species are further distinguished from congeners in lacking a nuchal concavity (present in all other

The post-Pleistocene isolation of the North Sunda River was probably the significant vicariant event leading to speciation of sister taxa in mainland and Sundaic Southeast Asia in freshwater fishes (Bornbusch &amp; Lundberg, 1989). These sister species (consisting of distinct Sundaic and mainland Southeast Asian species) had long been assumed to be a single species widely distributed in large rivers throughout Southeast Asia, a phenomenon only recently acknowledged to exist in many freshwater fish groups. This is the most likely scenario for the speciation of
