Краткое описание определительные ключи | морфология | морфометрия

Diagnosis: Distinguished from its congeners by the conspicuously banded dorsal fin; presence of fleshy excrescence on posterior tip of supraoccipital; typically 9 branched dorsal-fin rays (rarely 8 or 10); and evertible cheek plates with 2-4 hypertrophied odontodes. Chaetostoma changae differs from species described from the same drainage as follows: C. breve has 5-8 and C. dermorhynchum 4-5 hypertrophied odontodes on evertible cheek plates (vs. 2-4); C. carrioni does not have adipose and anal fins (vs. presence); C. dermorhynchum has 5 ramified anal-fin rays (vs. 3-4); C. branickii, C. lineopunctatum, C. loborhynchos, C. marcapatae, C. marmorescens, C. mollinasum, C. sericeum, and C. taczanowskii have 6 infraorbital plates (vs. 7) and first anal-fin ray with 2 or more rows of odontodes along its anterior border (vs. first anal-fin ray without odontodes); C. greeni, C. marcapatae and C. sericeum have a wide interorbital width: 37.048.0% HL (vs. 28.3-32.4% HL) and numerous hypertrophied odontodes on evertible cheek plates: 7-12 (vs. 2-4); branickii has a reduced triangular sphenotic (vs. square); lineopunctatum has dark spots on body (vs. uniformly pigmented); loborhynchos, marmorescens, mollinasum, taczanowskii exhibit rounded papillae on the naked snout (vs. irregularly shaped papillae) and straight hypertrophied odontodes on evertible cheek plates (vs. hooked); loborhynchos, marmorescens, mollinasum, and taczanowskii lack the longitudinal fleshy excrescence on the posterior tip of the supraoccipital, a fleshy projection on the middle third on the anterior soft border of dentary, and contact between sixth infraorbital and suprapreopercle (Ref. 56969).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01585 (0.00685 - 0.03669), b=2.97 (2.80 - 3.14), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
