abstract (from publication):
The type material of Xiphophorus heckelii Weyenbergh, 1874 and X. obscurus Weyenbergh, 1877 has apparently been re-examined for the first time. Xiphophorus heckelii is confirmed as a junior synonym of Jenynsia multidentata (Jenyns, 1842). Xiphophorus obscurus is recognized as a senior synonym of Jenynsia pygogramma Boulenger, 1902, which is placed in synonymy. A lectotype and paralectotypes for Jenynsia obscura (Weyenbergh, 1877) are designated.
