Etymology: Hypostomus: Greek, hypo = under + Greek, stoma = mouth (Ref. 45335); peckoltoides: The specific name refers to the genus Peckoltia, which includes species with dark saddles similar to that found in the new species, and is derived from the name of the genus proposed by Miranda-Ribeiro (1912), in honor of Mr. Gustavo
Peckolt, plus the Greek suffix -öides meaning to resemble.

簡短描述
檢索表 | 型態特徵 | 形態測量圖
背棘 (總數) : 1; 背的軟條 (總數) : 8. Can be diagnosed from all other members of the genus Hypostomus, except the young specimens of Hypostomus latifrons, by having wide dark transverse bars on body and bands on the fins (vs. body entirely dark or with pale or dark spots); and by the conspicuous dark vermiculations on abdominal region (vs. abdominal region entirely dark or with pale or dark spots). Differs from Hypostomus latifrons by having the dark bars on the sides and bands on the fins in adults (vs. spots present anteriorly and dark blotches posteriorly in adults), and by having just one pre-dorsal plate margining the supraoccipital (vs. three plates) (Ref. 85849).
Facultative air-breathing in the genus (Ref. 126274); Found in rio Cuiabá of the upper rio Paraguay basin characterized by turbid water, rocky with sand substrate, and variable remnant riparian vegetation. Occurs syntopically with Hypostomus boulengeri, H. cochliodon, H. latifrons, H. latirostris, H. regani and another putative undescribed species of Hypostomus (Ref. 85849).
