Astyanax lineatus (Perugia, 1891)

‘ ASTYANAX’ LINEATUS View in CoL CLADE

Composition: ‘ Astyanax ’ lineatus ( Perugia, 1891) , ‘ Astyanax ’ metae Eigenmann, 1914 , ‘ Astyanax ’ pirapuan Tagliacollo et al., 2011 and ‘ Astyanax ’ venezuelae Schultz, 1944 .

The monophyly and, eventually, the composition of this clade should be further investigated. In this analysis it is supported by ten molecular and one morphological synapomorphy: sheath of scales covering three-quarters or more of the anal-fin base (469:0).

Among the species in this clade, only ‘ Astyanax ’ lineatus has both morphological and molecular data available. The remaining species were analysed only from sequences of COI. The obtained relationships of this clade suggest the need of creating a new generic name for it. However, given the low amount of available data for most of the analysed species, we prefer to keep these species provisionally as incertae sedis in Gymnocharacini.
