Identification Centromochlus ferrarisi is distinguished from all other Centromochlinae, except C. meridionalis, by having dorsal and lateral surfaces of head and body darkly mottled with many small rounded blotches, blotches closely spaced, often coalescent and rather poorly delimited on a pale background (versus dorsolateral surfaces either uniformly dusky or dark, with pale blotches on a darker background, or with a few large dark blotches or spots well spaced and well defined on a pale background). The new species differs from C. meridionalis by having the dorsal-fin spine with serrations anteriorly and smooth posteriorly (versus dorsal-fin spine smooth anteriorly and with serrations posteriorly), seven branched anal-fin rays of mature males (versus six) and posterior nuchal plate short, not extended anteroventrally (versus posterior nuchal plate with anteroventral extension).

Hop to next section Husbandry Information
Furniture This species was identified from a small headwater stream, approximately 1m wide and 1m deep, with moderate current. The stream bottom was mostly sand and silt, with some pebbles. The water is clear, but with some suspended particulates. Part of the stream forms a canyon through a sandstone area, with a riparian forest below the canyon. The fish hide under submerged logs.
