簡短描述

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).
鑑別: 顯著地與它的同類區分藉由帶了背鰭; 在上枕骨的後頂端上有肉質的贅肉; 典型地 9個分枝的背鰭鰭條;(很少地 8 或 10) 而且 evertible 頰碟有 2-4 肥大齒。 Chaetostoma changae 依下列各項有別於描述從的種相同的流域: C. 短音符 在 evertible 頰碟上有 5-8 與 C. dermorhynchum4-5 肥大的齒;(vs.2-4) C. carrioni 不會有脂鰭與臀鰭;(vs. 出現) C. dermorhynchum 有 5個分枝的臀鰭棘條;(vs.3-4) C. branickii ， C. lineopunctatum ， C. loborhynchos ， C. marcapatae,
C. marmorescens ， C. mollinasum, C. sericeum, 與 C. taczanowskii 有 6個眶下的碟 (vs.7) ，而且第一個臀鰭鰭條有兩個或更多列的齒沿著它的前緣;(vs. 沒有齒的第一個臀鰭鰭條) C. greeni, C. marcapatae 與 C. sericeum 有一個廣泛的眼間骨寬度: 在 evertible 頰碟上的 37.048.0% HL(vs.28.3-32.4% HL) 與很多的肥大齒: 7-12;(vs.2-4) branickii 有一個縮小的三角形的蝶骨;(vs. 正方形) lineopunctatum 在身體上有深色的斑點;(vs. 均勻地著色的) loborhynchos ， marmorescens ， mollinasum, taczanowskii 在 evertible 頰碟上在裸露的吻 (vs. 形狀不規則的乳突) 與直的肥大上展現圓形的乳突齒;(vs. 鉤狀的) loborhynchos ， marmorescens ， mollinasum 與 taczanowskii
在上枕骨的後面的頂端上缺乏縱向的肉質贅肉, 在齒骨的前面軟邊緣上的中央三個上的一個肉質的突出, 與第六的眶下和 suprapreopercle 之間的接觸在一起.(參考文獻 56969)
