Etymology: Hypostomus: Greek, hypo = under + Greek, stoma = mouth (Ref. 45335); macushi: Named for the Macushi people of the northern Rupununi who provided the authors with a lot of help and hospitality on their trips to Southern Guyana and who collected most of the best specimens in the type series.
Eponymy: The Macushi people of the northern Rupununi, southern Guyana, gave the authors a great deal of help and hospitality. They collected most of the best specimens in the type series. (Ref. 128868), visit book page.

Short description
पहचान कुंजी | आकृति विज्ञान | मौरफोमैटरिक्स
पृष्ठीय रीढ़ (सम्पूर्ण) : 2; पृष्ठीय सौफट रेज़ (सम्पूर्ण) : 7; गुदा कांटा: 1; ऐनल सौफट रेज़: 4. Distinguished from all other Hypostomus except the species of the H. cochliodon group based on the presence of large, spoon-shaped teeth; and from all members of the H. cochliodon group except H. cochliodon, H. ericae, H. ericius and H. paucipunctatus by the presence of very widely spaced black spots on a light background. Can be separated from H. cochliodon by absence of a longitudinal ridge on the pterotic-supracleithrum and absence of longitudinal dark stripes; from H. ericius by lacking keels formed from sharp odontodes on the lateral plates; from H. ericae and H. paucipunctatus by lacking a buccal papilla; from H. ericae by having spots in the distal dorsal and caudal fins not combining (vs. spots combining to form wavy lines); and from H. paucipunctatus by having medium to large spots. It is further distinguished by having seven to eight adipose-caudal plates and by generally having no odontodes on the opercle (zero to 10), vs. having a patch of greater than 10 odontodes on the opercle (Ref. 54531).
Facultative air-breathing in the genus (Ref. 126274); Occurs among submerged, dead wood in modest to swift flowing water (Ref. 54531). Inhabiting largest part of freshwaters, from headwaters to upstream of the lower falls, with rocky substrate consisting of boulders, stones, gravels, and sand; the exposed wet rocks are also often covered by the Podostemaceae Mourera fluviatilis and Apinagia richardiana (Ref. 90186).
