簡短描述
檢索表 | 型態特徵 | 形態測量圖
背的軟條 (總數) : 8; 臀鰭軟條: 5; 脊椎骨: 28. Can be easily distinguished from all congeners except Ancistrus reisi and A. jataiensis by lacking adipose fin. A series of 3 to 5 median, unpaired platelets forming a low crest is present in place of adipose fin. Platelets are followed by at least two dermal plates (more often three) of the dorso-lateral series that join dorsally, vs. platelets nearly immediately followed by the plate-like procurrent caudal rays in A. reisi and A. jataiensis. It further differs from all species of Ancistrus by the unique combination of the following characters: naked margin of snout large and tentacles usually absent in both sexes, body very narrow (cleithral width 27.5-31.2% SL, mean 29.4), and long caudal peduncle particularly depressed (depth 8.3-9.2% SL, mean 8.7) (Ref. 54498).
除了缺乏脂鰭的 Ancistrus reisi 與 A. jataiensis 以外可能是與容易地區分的所有同類。 一系列的 3 到 5個形成一個低的冠中央又不成對的小板是出現在脂鰭的地方。 小板被跟隨著至少被 vs. 小板幾乎緊鄰在 A. reisi 與 A. jataiensis 中跟隨著板狀的前流尾部的鰭條的背面結合的背-側系列的二個真皮板 (更時常三) 。 它進一步有別於下列特徵的組合 Ancistrus 的所有種: 裸露邊緣吻大的與觸鬚通常不存在於兩性，身體非常狹窄的 (匙骨寬度 27.5-31.2% SL, 平均的 29.4), 與特別地被扁平的 (深度 8.3-9.2% SL, 平均的 8.7) 的長的尾柄.(參考文獻 54498)
