Description: Dorsal spines (total): 2; Dorsal soft rays (total): 7-8; Anal soft rays: 6; Vertebrae: 22. Distinguished from all other congeners, except Otocinclus cocama, by having a single, intensely pigmented, vertical W-shaped caudal fin spot and by having three discrete dark bands on dorsum, between the dorsal-fin base and the caudal fin. Can be separated from Otocinclus cocama by the absence of vertically elongated blotches from the dorsal midline to the ventral border of flanks, and by lacking the posterior extension of black pigmentation on the base of two central caudal-fin rays. Differs from most Otocinclus species, except Otocinclus bororo, Otocinclus cocama, Otocinclus mariae, Otocinclus mura, and Otocinclus huaorani, by possessing 20 or more teeth in both the premaxilla and dentary (vs. less that 20 in all other species). Aquarium Care: This is a small group of Loricariids which do well in aquaria and will keep the algae down without harming the plants in the tank. Best to keep in a group with more males for breeding purposes. Reproduction: The females will lay eggs on the plants and tank glass after the females have been chased around the tank by the male. Like Corydoras they present a t-position breeding mode. Diet: Omnivore: algae, tablet foods, flake and small frozen foods. Etymology: The name batmani, alludes to Bob Kane's hero Batman of the comic adventures, which had a bat shape for his symbol, referring to the single W- or bat-shaped vertical spot on the caudal-fin.
