背棘 (总数) : 1; 背的软条 (总数) : 7; 臀鳍软条: 6; 脊椎骨: 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).
