|discussion=<p>In the past <i>Pleopeltis riograndensis</i> has been treated as a variety of P. thyssanolepis, but it differs from the latter species in that the petiole and leaf are only sparsely scaly rather than densely so, the blade scales are mostly ovate or ovate-lanceolate rather than nearly spheric, the venation is mostly free rather than mostly areolate, and the basal segments of the blade are alternate rather than opposite to nearly opposite.</p>
