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..

简单描述
型态特徵 | 形态测量图
背棘 (总数): 2; 背的软条 (总数): 7; 臀棘 1; 臀鳍软条: 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).
除了 H. cochliodon 群的此鱼种以外与所有的其他 Hypostomus 区分以那为依据有大的, 匙-形状的齿; 而且从 H. cochliodon 的所有成员除了 H. cochliodon ， H. ericae 以外聚集, H. ericius 与 H. paucipunctatus 藉由在淡的背景上有非常空隙大的黑色斑点。 能被与 H. cochliodon 分开被在 pterotic 上缺乏一個縱向的脊-supracleithrum 而且缺乏縱向的深色斑紋; 從缺乏龍骨脊的 H. ericius 在側骨板上從銳利的齒形成了; 從 H. ericae 與 H. paucipunctatus 藉著缺少口的乳突; 從 H. ericae 在末梢部的背鰭與尾鰭鰭藉著具有斑點不聯合;(vs. 正在聯合形成波浪狀的線的斑點) 而且從 H. paucipunctatus 藉著具有中等的對大的斑點。 它是進一步藉著有七到八個脂鰭-尾鰭碟區別與在通常之前沒有齒在鰓蓋 (零到 10) 上, vs. 有一個在鰓蓋上的大於 10個齒的小區塊.(參考文獻 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).
