背的软条 (总数) : 8; 臀鳍软条: 5; 脊椎骨: 28. Distinguished from all congeners except Ancistrus tombador and A. reisi by the absence of an adipose fin. Adipose fin is replaced by a series of 2 to 4 median unpaired platelets forming a low crest. These platelets are nearly immediately followed by the plate-like procurrent caudal rays, while in A. tomabador these are followed by at least two lateral plates that join dorsally before the procurrent caudal rays. It further differs from A. tombador by the following characters: snout with naked margin generally ill-delimited by posterior dermal plates which are irregular in size and shape and rarely joined together; tentacles present, some branched in larger males; body wider (cleithral width 33.6-35.6% SL, mean 34.9) and caudal peduncle depth 10.1-10.7% SL, mean 10.4. Differs from A. reisi by the following morphometric characters: predorsal length (47.5-49.3% SL, mean 48.1, vs. 43.8-46.4% SL, mean 44.9), occipital depth (17.0-19.5% SL, mean 18.1, versus 14.9-17.0% SL, mean 16) and caudal peduncle length (24.6-27.1% SL, mean 26.3, vs. 27.7-30.9%SL, mean 28.7) (Ref. 54498).
除了 Ancistrus tombador 与 A. reisi 藉由缺少一个脂鳍以外与所有的同类区分了。 脂鳍被形成一个低的冠的一系列的 2 到 4个中央的不成对的小板取代。 这些小板紧邻几乎被跟随着板状的前流尾部的鳍条而在 A. tomabador 中这些被跟随着至少二个背面在前流的尾部鳍条之前结合的侧骨板。 它进一步在特征之后有别于 A. tombador 藉由: 吻部有通常有害界定的裸露的边缘借着在后部真皮板那是不规则的在大小与形状中而且很少地一起結合; 觸鬚呈現, 在較大的雄性中的一些分枝; 身體比較寬的 (匙骨寬度 33.6-35.6% SL, 平均的 34.9) 與尾柄深度 10.1-10.7% SL, 意謂 10.4. 在型態特徵的特徵之後有別於 A. reisi 藉由: 前背的長度 (47.5-49.3% SL, 平均的 48.1, vs.43.8-46.4% SL, 平均的 44.9), 後頭骨深度 (17.0-19.5% SL, 平均的 18.1, 對 14.9-17.0% SL, 平均的 16) 與尾柄長度 (24.6-27.1% SL, 平均的 26.3, vs.27.7-30.9%SL, 平均的 28.7).(參考文獻 54498)
