Etymology: Ferrarissoaresia: Named after C. Ferrarris and Soares; ferrarisi: Named for C. J. Ferraris Jr., for his numerous contributions to the systematics of Siluriformes, especially Auchenipteridae, including the first hypothesis recognizing Centromochlinae as sister to all other Auchenipteridae..

Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 2; Dorsal soft rays (total): 5; Anal soft rays: 10; Vertebrae: 35. Centromochlus ferrarisi can be diagnosed from all species of Centromochlinae, with the exception of 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 (v. 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). It can be distinguished from C. meridionalis by having the dorsal-fin spine with serrations anteriorly and smooth posteriorly (v. dorsal-fin spine smooth anteriorly and with serrations
posteriorly), seven branched anal-fin rays of mature males (v. six) and posterior nuchal
plate short, not extended anteroventrally (v. posterior nuchal plate with anteroventral
extension). It further differs from C. altae, C. existimatus, C. heckelii, C. meridionalis, C. perugiae, C. reticulatus and C. romani by possessing seven branched anal-fin rays (v. five or six); from C. macracanthus and C. schultzi by having short pectoral-fin spine, c. 15% of SL (v. long pectoral-fin spine, 25% of SL); from C. concolor and C. punctatus by its short posterior cleithral process, c. 5% of SL (v. c. 20% of SL); from C. altae, C. existimatus, C. heckelii and C. perugiae by the absence of the anterior nuchal plate (v. presence); from C. romani by having anterior margin of dorsal-fin spine with serrations (v. smooth); from C. simplex by having adipose fin well developed (v. minute) (Ref. 104786).
The type locality is a small headwater stream with width of 1-1.5 m, depth of 0.3-1.0 m, moderate current and bottom composed of sand-silt and pebbles in some stretches. Collected near submerged logs, and caught by overturning a log with the hand-net positioned immediately below. Occurs syntopically with Knodus cf. savannensis (Characidae), two species of Phenacorhamdia (Heptapteridae), and Melanorivulus cf. zygonectes (Rivulidae) (Ref. 114786).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01122 (0.00514 - 0.02450), b=3.04 (2.87 - 3.21), in cm total length, based on all LWR estimates for this body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.3 ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref.
120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
