(Catfish) > Malapteruridae
Etymology: Malapterurus: Greek, mala = a lot of + Greek, pteron = fin + Greek, oura = tail (Ref. 45335); punctatus: From the Latin "punctum" = little spot, in reference to the finely spotted dorsum and flank typical of this species (Ref. 44050).
Environment: milieu / climate zone / depth range / distribution range
Freshwater; benthopelagic. Tropical
Africa: St. Paul (or Diani) River system (Sierra Leone) to the Cavally River system (Liberia/Ivory Coast) (Ref. 44050, 57130). Also reported from the Waanje River (Sierra Leone)(Ref. 44050)

Morphology | Morphometrics
soft rays: 8 - 10;
Vertebrae: 38 - 39. Diagnosis: tooth patches broad; 8-10 anal-fin rays; 20 caudal-fin rays (nearly always ii-7-8-iii); 38-39 vertebrae; body and head only slightly depressed; snout and head relatively blunt (in dorsal and lateral profile); eyes more or less lateral; body colored in shades of grey; lower lip and underside of head not especially darkened or stippled; dorsum and flank finely spotted; paired fins frequently spotted in adults; caudal fin darkly pigmented with a pale distal margin, but no pale basal crescent (young up to 70mm SL have a pale spot at the base of the caudal fin but no well-developed crescent or bar) (Ref. 44050).
