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. 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 與 A. jataiensis 藉由缺少一個脂鰭以外與所有的同類區分了。 脂鰭被形成一個低的冠的一系列的 2 到 4個中央的不成對的小板取代。 這些小板緊鄰幾乎被跟隨著板狀的前流尾部的鰭條而在 A. tombador 中這些被跟隨著至少二個背面在前流的尾部鰭條之前結合的側骨板。 (參考文獻 54498) 藉由跟隨特徵與 A. tombador 區分了: 吻部有通常有害界定的裸露的邊緣藉著在後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, 意謂 26.3).(參考文獻 54498)
