Hyphessobrycon luetkenii (Boulenger, 1887)

Mirande, Juan Marcos, 2010, Phylogeny of the family Characidae (Teleostei: Characiformes): from characters to taxonomy, Neotropical Ichthyology 8 (3), pp. 385-568 : 513

Node 271: Hyphessobrycon luetkenii clade (46 / 81 / – / 2)

Astyanax latens , other Astyanax ?, Hyphessobrycon bifasciatus , H. luetkenii , other Hyphessobrycon ?

The species in this clade were included in the Astyanax clade in the hypothesis of Mirande (2009). According to the present hypothesis a new genus should be assigned to these species, given that the type species of Astyanax ( A. mexicanus ) is included in the Astyanax clade, and the type species of Hyphessobrycon ( H. compressus ), although not herein analyzed, is presumably included in the Tetragonopterinae along with the members of the rosy tetra clade of Weitzman & Palmer (1997). This node is rather stable across the analyses done for this study, however, its position is variable, lying within the Astyanax clade in some of them. Thus, both the monophyly and position of this clade should be further tested.
