'' (another armored catfish known as the "common plecostomus"). The two species can be distinguished by their number of dorsal rays. ''P. pardalis'' has 11–13, while the ''H. plecostomus'' has only 5–8 dorsal rays. It is also commonly misindentified as ''P. disjunctivus'' and can be differentiated by its spotted patterning. There is an albino color variation of this species, usually referred to as an "Albino Plecostomus". The amelanistic form may also be sold as the "chocolate pleco".
