Descrição breve
Chaves de identificação | Morfologia | Morfometria
Espinhos dorsais (total) : 1; Raios dorsais moles (total) : 7; Raios anais moles: 6; Vértebras: 27. Leptotocinclus ctenistus can be diagnosed from its only congener L. madeirae by the presence of median series of abdominal plates, arranged in one single row (vs. median series of abdominal plates absent); and having 3-6 lateral abdominal plates (vs. 1-2, but one specimen with 3). It further differs by having larger size of preanal plate (7.0-12.0% SL vs. 1.5-6.4% SL) (Ref. 116855).
Body shape (shape guide): elongated.
Collected from blackwater creeks and small rivers (Ref. 116855).
