Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 1; Dorsal soft rays (total): 7; Anal soft rays: 6; Vertebrae: 26. Leptotocinclus madeirae can be diagnosed from its congener L. ctenistus by the absence of a median series of abdominal plates (vs. presence of median series of plates, arranged in one single row) and by having 1-2 (except one specimen with 3) lateral abdominal plates (vs. 3-6). It further differs by having smaller size of the preanal plate (1.5-6.4% SL vs. 7.0-12.0% SL) (Ref. 116855).
Collected from blackwater creeks and small rivers (Ref. 116855).
