Description synthétique
Morphologie | Morphométrie
Épines dorsales (Total): 1; Rayons mous dorsaux (Total): 7; Rayons mous anaux: 6; Vertèbres: 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).
