Bagre Cloquet, 1816

MP 100, BI 1, ML 100

( Figs 1–3 , 4A , 6 )

Type species: Silurus bagre Linnaeus, 1766 .

Diagnosis

That of the Bagreinae , above.

Included species

Bagre bagre Linnaeus, 1766

Bagre filamentosus Swainson, 1839

Bagre marinus Mitchill, 1815

Bagre panamensis Gill, 1863

Bagre pinnimaculatus Steindachner, 1876 .

Habitat and distribution: Predominantly marine, eastern and western America ( Fig. 4 ).

Remarks

The MP and ML analyses corroborate the morphological diagnosis, species composition, and the hypothesis of phylogenetic relationships of Bagre presented in previous morphological studies ( Marceniuk and Menezes 2007, Marceniuk et al. 2012). With different interpretations of phylogenetic relationships, Kailola (2004), Betancur-R. et al. (2007), and Betancur-R. (2009) show the same definition and species composition as found in the total-evidence analysis.
