species, although the tubercles are often small and may be obscured by a thick layer of congealed mucus in preserved material. Furthermore, the tubercles are easily damaged (e.g. when we attempted to remove the layer of congealed mucus by rubbing), making it more difficult to study this character. In summary, it is possible that tubercle shape may be useful in diagnosing

species, but its worth could not be fully assessed in our study. We note, however, that tubercle shape has been used as diagnostic characters in other catfish groups, most notably in sisorids (Mo & Chu, 1986) and mochokids (Roberts, 1989; Ng, 2004); its utility as a diagnostic character for silurids warrants further investigation. The tubercles presumably enlarge during breeding, as is the case with other ostariophysans (Wiley & Collette, 1970), but we do not understand enough of the biology of these fishes to be fully certain.
