الأشواك الظهرية (المجموع) : 2; الأشعة الظهرية الناعمة (المجموع) : 7; شوكة شرجية: 0; أشعه شرجية لينه: 5; فقرات: 29. Diagnosis: Hypostomus melanephelis is distinguished from the congeners, except H. interruptus, H. paucimaculatus, H. micropunctatus, H. nigropunctatus, and H. rhantos, by having conspicuous dark, roundish and tiny (smaller than eye pupil) set of dark spots on trunk (vs. medium to large pale or dark spots [larger than eye pupil], or transversally elongated dark spots); Hypostomus melanephelis is distinguished from H. interruptus, H. paucimaculatus, H. micropunctatus, H. nigropunctatus, and H. rhantos by the naked to partially plated abdomen (vs. abdomen completely covered by platelets); it is further diagnosed from H. interruptus by a larger mandibular ramus, 18-22 % HL (vs. 11.6-17.5 % HL; from H. paucimaculatus by having villiform bicuspid non spoon-shaped teeth with the lateral cusps not fused to the mesial tooth (vs. massive spoon-shaped teeth with lateral cusps usually fused to the mesial tooth); from H. micromaculatus by having usually 1 row of spots on each interradial membrane of dorsal fin (vs. 4-5) moderately distant from each other on flanks (vs. densely settled spots); from H. nigropunctatus by having just 1 plate posteriorly bordering supraoccipital (vs. 3); and from H. rhantos by having a more depressed head 49-56 % SL (vs. a more deeper head 64.3-83.2 % HL (Ref. 103391).
Body shape (shape guide): elongated.
Facultative air-breathing in the genus (Ref. 126274); Collection area included different sections of running waters on large extensions of rocky substrate (Ref. 103391).
