Hemisilurus moolenburghi Weber and de Beaufort, 1913 View in CoL
(®gure 6) Hemisilurus moolenburghi Weber and de Beaufort, 1913: 212 , ®gures 84, 85 (type locality: Batang Hari, Sumatra); Roberts, 1989: 145; Kottelat et al., 1993: 68, ®gure 161.
Material examined. BATANG HARI DRAINAGE: ZMA 113 View Materials .564 (2), syntypes, 315.0± 404.0 mm SL. ZRC 41530 (14) , 294.0±378.0 mm SL. ZRC 41904 (6) , 281.0± 414.0 mm SL.
Remarks. This large silurid is a highly esteemed food ®sh and commands a high price in the local markets. Hemisilurus moolenburghi exhibits sexual dimorphism in both morphology and colour. Like most other silurid genera, males have more prominent serrations on the posterior edge of the pectoral spine than females and simple unbranched maxillary barbels (®gure 6) while females have elongated maxillary barbels with the tips branching into three ®laments. Sexual dimorphism in morphology has been recorded for other species of Hemisilurus (see Bornbusch and Lundberg, 1989). Crabs ( Varuna yui Hwang and Takeda, 1986 ; family Grapsidae ) and prawns ( Macrobrachium sp. ; family Palaemonidae ) were found in the guts of two specimens dissected.
