Galeichthys Valenciennes, 1840

MP 100, BI 1, ML 100

( Figs 1–3 , 4A – 5 )

Type species: Galeichthys feliceps Valenciennes, 1840 .

Diagnosis

That of the Galeichthyinae , above.

Included species

Galeichthys ater Castelnau, 1861

Galeichthys feliceps Valenciennes, 1840

Galeichthys peruvianus Lütken, 1874

Galeichthys trowi Kulongowski, 2010 *.

Remarks

Total-evidence analysis corroborated previous morphological ( Marceniuk and Menezes 2007, Marceniuk et al. 2012) and molecular (Betancur-R.2009) studiesregardingthemonophylyandrelationship of the genus. Supported by morphological and molecular data, Betancur-R. et al. (2007) had the same interpretation of the phylogenetic relationship of Galeichthys , examining only Galeichthys ater and Galeichthys peruvianus , whereas Kailola (2004), based only on morphological evidence, recognized the same species composition, but with a unique hypothesis of phylogenetic relationships.

Habitat and distribution: Marine, southern Africa, and north-western coast of South America ( Fig. 4 ).
