Notes:
This taxon has seen a number of transfers at the genus level. Patrick and Reimer (1975) report on why the genus Tropidoneis should be rejected in favor of Plagiotropis. Paddock (1988) did an extensive review of the two genera, Plagiotropis and Tropidoneis, but, unfortunately, did not examine the species Tropodoneis laevissima. The taxon was recently transferred to Stauronella constricta.
