Populations previously identified as A. leptorhynchus based on samples originating in various rivers draining into Lago Maracaibo in both Colombia and Venezuela were found to be A. anu based on the collecting localities (Ref. 93867).

ຄີກົ້ນຂອງປາ: 159 - 176; ສັດທີ່ມີກະດູກສັນຫຼັງ: 70 - 83. This species can be distinguished from its congeners by the following set of characters: A 159-176; P 14-16; C 10-13; precaudal vertebrae 18-19; total vertebrae 70-83; 5th infraorbital present as a tubular laterosensory canal segment; cartilaginous lateral ethmoid; the number of scales above the lateral line at the midbody 7-9; the number of scales along the lateral line 59-63; the extent of the mid-dorsal groove (extending seven to eight scales beyond the vertical through the posterior terminus of the anal fin); tail length 17.1-37.5% of LEA; interorbital distance 14.7-36.5% of HL. Colouration: head and body dark brown from a lateral view with the fins apparently hyaline; distinct pale, broad, longitudinal band extends from chin along dorsal midline of head and body to over dorsal filament; pectoral and anal-fin rays ranging from translucent to dark brown with interradial membranes translucent; pale band encircling base of caudal fin; caudal fin pale at base, pale to black on central portion and translucent posteriorly (Ref. 93867).
Inhabits swift current habitats over substrates of rounded stones. It was observed that this species is a voracious nocturnal predator (Ref. 93867).
