Remarks: Jordan (1923: 138) proposed the new name Apteronotidae for the family previously named the Sternarchidae, in conjunction with his treatment of Sternarchus as a junior synonym of Apteronotus , based on the then-prevailing view that family names needed to be derived from valid generic names. Despite its clear priority, the name Sternarchidae has been used rarely since the introduction of the name Apteronotidae , and the Apteronotidae is in widespread use. FollowingArt. 40.2 of the Code of Zoological Nomenclature (ICZN, 1999), the name Apteronotidae takes priority over Sternarchidae and takes as its date of publication that of Sternarchidae [= 1838] for purposes of priority among other gymnotiform family-group names.

Albert (2001) proposed the name Sinusoidea (p. 69) as a suprafamilial name and Navajini (p. 77) as a subgroup within the Apteronotinae . Those names are not available as family-group names inasmuch as they are not based on available generic names (ICZN, 1999: Art. 11.7.1.1).

Apteronotidae incertae sedis (2 species)

Sternarchus bonapartii Castelnau, 1855: 92 , pl. 45 (fig. 2). Type locality: un lac se de’versant dans l’Ucalaye [ Peru]. Holotype: MNHN 0000-3807; 24 cm TL.

Remarks: Treated as valid in Apteronotus in Mago-Leccia (1994), Albert (2001) and Cox Fernandes et al. (2002); as a senior synonym of Parapteronotus hasemani in Triques (2007a); and as a valid species within the Apteronotidae , but not assigned to any available generic name in Tagliacollo et al. (2016).

Distribution: Amazon River basin, Peru and Brazil (Albert, 2003a).

Porotergus ellisi Alonso de Arámburu, 1957: 154 , fig. 1. Type locality: San Pedro, provincia de Buenos Aires, sobra el Río Paraná inferior (en el Delta), Argentina. Holotype: MLP 1 -V- 37-3; 328 mm TL.

Remarks: Treated as valid in Porotergus in Mago-Leccia (1994); valid in Apteronotus in Albert (2001); and as a valid species within the Apteronotidae , but not assigned to any available generic name in Tagliacollo et al. (2016).

Distribution: Paraná River basin, Argentina ( Alonso de Arámburu, 1957).

ADONTOSTERNARCHUS Ellis, 1912 (6 species)

Adontosternarchus Ellis , in Eigenmann, 1912: 424. Type species: [ Sternarchus sachsi Peters, 1877 ]. Type by subsequent monotypy. Gender: masculine.

Revision with key to species: Mago-Leccia et al. (1985).

Remarks: Adontosternarchus appeared first in Ellis (in Eigenmann, 1912) without reference to any species. The name was listed with one included species, Sternarchus sachsi Peters, 1877 , in Ellis (1913: 155).
