Description: Dorsal spines (total): 1; Dorsal soft rays (total): 7; Anal soft rays: 12 - 14; Vertebrae: 35 - 36. Can be differentiated further from all congeners except Pseudomystus breviceps, Pseudomystus bomboides, Pseudomystus flavipinnis, Pseudomystus myersi, Pseudomystus siamensis, Pseudomystus robustus, Pseudomystus sobrinus and Pseudomystus stenomus in having a deeper body (17.8-21.0% SL vs. 9.0-17.0). Differs from Pseudomystus leiacanthus in having two (vs. one) dark narrow irregular bars on the caudal fin, longer pectoral spine (19.3-22.4% SL vs. 15.2-18.6), longer caudal fin (33.5-40.0% SL vs. 25.7-31.9) with pointed (vs. rounded) lobes, longer nasal and maxillary barbels (63.1-81.1% HL vs. 31.3-51.5 and 86.2-125.3% HL vs. 70.9-91.3 respectively; nasal barbel reaching to dorsal insertion of opercular flap vs. to just beyond posterior orbital margin and maxillary barbel reaching just beyond base of last pectoral-fin ray vs. to base of pectoral spine), a straight ( vs. crescentic) premaxillary tooth patch, a more sharply tapering snout when viewed dorsally and an even (vs. slightly convex) predorsal profile. Colouration: Differs from its congeners in possessing a colour pattern consisting of a pale midlateral stripe and two pale oblique bands on the sides of the body; no other congener exhibits a distinct pale midlateral stripe. Habitat: Occurs in floodplain channels and peat swamps with very acidic (pH 3.5-4.5), tannin-stained water. Etymology: The genus name Pseudomystus: Greek, pseudes = false + Greek, mystax = whiskered, used by Belon in 1553 to describe all fishes with whiskers. The species name is for one of the authors, Heok Hui Ng. |
