Etymology: Hypostomus: Greek, hypo = under + Greek, stoma = mouth (Ref. 45335); kopeyaka: After its common name among the Tuyuka and Tukano indians, kope yaka, or kope ya’ka, meaning “pleco from the holes”, an allusion to the fact that, according to the Indians, the fishes spend most of their time hiding in holes in the river ban.

South America: Brazil and probably Colombia. Hypostomus kopeyaka is known only from the rio Tiquié basin, a tributary of the rio Uaupés, upper rio Negro drainage, Brazil. According to Tuyuka fishermen, the species also occurs at the upper rio Tiquié into Departamento Vaupés in Colombia, but no specimens are available from the latter area (Ref. 83896).

وصف مختصر
مفاتيح التعريف | الوصف الخارجي | قياسات المظهر الخارجي
Distinguished from all congeners, except those belonging to the Hypostomus cochliodon group, by having few teeth (10 to 13) bearing a small lateral cusp and acutely angled dentaries. Diagnosed from the remaining members of the Hypostomus cochliodon group, except H. hemicochliodon, H. sculpodon, H. soniae Hollanda, Carvalho & Weber, and H. weberi, by possessing bicuspid teeth with mesial cusp rounded, considerably larger than outer cusp (vs. teeth generally unicuspid, outer cusp, if present, almost imperceptible, mesial cusp large and distinctly spoon-shaped). Hypostomus kopeyaka can be distinguished from H. hemicochliodon, H. sculpodon, H. soniae, and H. weberi by a distinctive color pattern composed of conspicuously horizontally elongated, closely-set black spots on the head and dorsal surfaces of the body (vs. spots absent in H. soniae, spots present but rounded in the remaining species, spots small in H. hemicochliodon and H. sculpodon, and large and widely-set in H. weberi). Additionally, it is differs from all the members of the Hypostomus cochliodon group, except H. weberi, H. ericae Hollanda Carvalho & Weber, H. hemicochliodon, H. paucipunctatus Hollanda Carvalho & Weber, H. sculpodon and H. waiampi Hollanda Carvalho & Weber, by possessing a buccal papilla (Ref. 83896).
Body shape (shape guide): elongated.
Facultative air-breathing in the genus (Ref. 126274); Found in rapids, cataract pools, and slow-flowing portions of the rio Tiquié and some large tributaries (Ref. 83896).
