P. hodgarti is diagnosed by having no post-labial groove (unlike other members of Glyptosternina), gill openings not extending to the underside,
homodont dentition, pointed teeth in both jaws, tooth patches joined into a
crescent-shaped band in upper jaw, and 13–16 branched
pectoral fin rays. This fish species has a depressed head. The body is elongate, and it is depressed anteriorly. The skin is smooth dorsally but often
tuberculate on the underside of the body. The lips are thick, fleshy, and
papillated. The eyes are minute, dorsally located, and subcutaneous (under the skin). The gill openings are narrow, not extending below the pectoral fin base. The paired fins are
plaited to form an adhesive apparatus. This species grows to a length of
TL. ==References==
