Remark: New combination with type species designation by Bleeker (1862:2); information on type and locality by Boeseman (1972:304); see Le Bail et al. (2000:250, fig.) for a complementary description with biological observations.
Comments: Known to scientists from only a few specimens.  According to Boni fishermen in Guiana, this fish lives in the deep and rocky zones of the main riverbed.  Despite its size, it is not consumed as food by native populations since it has a reputation for being dirty and sticky (Ref. 35381).
