Ophicephalus mystax Bleeker, 1853: 188 . Material examined. Table 1 . This species can be distinguished from C. baramensis (former considered a junior synonym of C. melasoma , currently a valid species) by the absence of a black spot in the centre of numerous body scales (vs presence of a black spot in this region) and absence of a barred caudalfin pattern (vs presence of this pattern in specimens larger than 120 mm SL). This species inhabits medium-sized to large rivers ( Taki 1978 ) and occurs in shaded forest streams with sluggish, acidic water, and submerged roots and leaf litter substrates. It also appears to be mainly noc- turnal and feeds on small animals ( Lim et al. 2008 ). Siluriformes
