🔬 Taxonomy
🐟 Physical Description
Dorsal soft rays (total): 8; Anal soft rays: 5; Vertebrae: 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 . 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) . : elongated.
