HYPOPOMUS Gill, 1864 (1 species)

Hypopomus Gill, 1864: 152 . Type species: Rhamphichthys mulleri Kaup, 1856 . Type by monotypy. Gender: masculine.

Brachyrhamphichthys Günther, 1870: 6. Type species: Rhamphichthys artedi Kaup, 1856 . Type by subsequent designation by Eigenmann, Ward (1905: 169). Gender: masculine. Proposed as a subgenus of Rhamphichthys .

Parupygus Hoedeman, 1962a: 58 . Type species: Parupygus savannensis Hoedeman, 1962 . Type by monotypy. Gender: masculine.

Remarks: The gender of Hypopomus was not stated in Gill (1864); and has been treated as feminine in Mago- Leccia (1994), Eschmeyer (1998), and Eschmeyer et al. (2016). However, the name appears to be derived from the transliterated Greek word poma (operculum), that was assigned a latinized suffix (pomus), thereby falling under the provisions of Art. 30.1.3 of ICZN (1999), which requires that the genus be treated as masculine.
