A key <strong>to</strong> <strong>South</strong> <strong>Asian</strong> <strong>Puntius</strong> s. l.<br />
The following key allows generic allocation <strong>of</strong><br />

from 1990-2010. Generic names in quotes indicate<br />
provisional assignment pending future revision;<br />
such species are unlikely members <strong>of</strong> <strong>the</strong> stated<br />
