Etymology: Placidochromis: Latin, placidus = of peaceful or tranquile appearance + Greek, chromis = a fish, perhaps a perch (Ref. 45335); platyrhynchos: From the Greek "platus" = flat and "runchos" = snout, referring to the flattened snout (Ref. 55898).

Freshwater; benthopelagic; depth range 74 - 147 m (Ref. 55898). Tropical
Africa: endemic to Lake Malawi, present in Malawi and Tanzania (Ref. 55898).

Morphology | Morphometrics
(total): 15 - 16;
soft rays: 8 - 9. Diagnosis: differs from the other very elongate species (with body depth equal to or less than 31.0% SL) by its wide and horizontally flattened snout, greater body size (7.95-10.00cm versus 7.45 or less) and the absence of scales on the cheek; 6 vertical bars below the dorsal fin; snout 31.3-35.1 % head length; premaxillary pedicel 28.0-30.5 % head length; 3/2 or more inner tooth rows in oral jaws; lower jaw length 40.3-43.6% head length; head 36.3-38.3 %SL (Ref. 55898).
