简单描述
型态特徵 | 形态测量图
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. jataiensis 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. tombador these are followed by at least two lateral plates that join dorsally before the procurrent caudal rays (Ref. 54498). Distinguished from A. tombador by 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, unbranched; body wider (cleithral width 31.6-34.5% SL, mean 33.1) and caudal peduncle depth 9.6-10.7% SL, mean 10.2. Differs from A. jataiensis by the following morphometric characters: predorsal length (43.8-46.4% SL, mean 44.9, vs. 47.5-49.3% SL, mean 48.1), occipital depth (14.9-17.0% SL, mean 16.0, versus 17.0-19.5% SL, mean 18.1) and caudal peduncle length (27.7-30.9% SL, mean 28.7, vs. 24.6-27.1%SL, mean 26.3) (Ref. 54498).
除了 Ancistrus tombador 与 A. jataiensis 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. tombador 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。 (参考文献 54498) 藉由跟随特征与 A. tombador 区分了: 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規則的在大小與形狀中而且很少地一起結合; 觸鬚呈現, 不分枝的; 身體比較寬的 (匙骨寬度 31.6-34.5% SL, 平均的 33.1) 與尾柄深度 9.6-10.7% SL, 意謂 10.2. 在型態特徵的特徵之後有別於 A. jataiensis 藉由: 前背的長度 (43.8-46.4% SL, 平均的 44.9, vs.47.5-49.3% SL, 平均的 48.1), 後頭骨深度 (14.9-17.0% SL, 平均的 16.0, 對 17.0-19.5% SL, 平均的 18.1) 與尾柄長度 (27.7-30.9% SL, 平均的 28.7, vs.24.6-27.1%SL, 平均的 26.3).(參考文獻 54498)
