The classification and total number of species in Pteronotropis is in a
state of flux. As far as I know, seven species are recognized, but genetic
analyses of hubbsi and welaka show that they are not related to other
members of the genus (Simons et al., 2000) and may warrant separate generic
status. The remaining five members may eventually number seven (or more)
once ichthyologists finish sorting through the various "races" that comprise
the sailfin shiner complex. (Expect metallicus to be reinstated soon.)

of the minnow genus Pteronotropis (Teleostei: Cyprinidae). Copeia 2000 (4):
