The subfamily Scaphirhynchinae is comprised of six The sturgeon subfamily Scaphirhynchinae contains two genera species, three in Scaphirhynchus from North America, and of obligate freshwater sturgeon: Scaphirhynchus and Pseudo- three in Pseudoscaphirhynchus from Central Asia (Nelson, scaphirhynchus, from North America and Central Asia, 1994; Mayden and Kuhajda, 1996). Life history strategies respectively. Both genera contain morphologically variable differ between these subfamilies (Bemis and Kynard, 1997) species. A novel data set containing multiple individuals with members of Acipenserinae exhibiting variable life history representing four diagnosable morphological variants for two strategies (i.e. anadromous, amphidromous, and potamodr- species of Pseudoscaphirhynchus, P. hermanni and P. kaufman- omous; Bemis and Kynard, 1997), while members of Scaph- ni, was generated. These data were used to test taxonomic irhynchinae complete all aspects of their life history as obligate hypotheses of monophyly for the subfamily Scaphirhynchinae, freshwater river inhabitants (potamodromous; Bemis and monophyly of both Scaphirhynchus and Pseudoscaphirhynchus, Kynard, 1997).
