This taxon is described here as new to science based on detailed light and scanning electron microscopic observations. The characteristics of this new species used to assign it to the genus <i>Geissleria </i>include triundulate valve margins, a straight and filiform raphe structure, lineolate striae, and the presence of annuli a circular or semi-circular hyaline area positioned on the valve apices. In <i>G. triundulata</i> sp. nov., the annulus is barely visible in light microscopy. The present study discusses the morphology of this new species compared to other <i>Geissleria</i> species, undertaking a thorough analysis of various morphological features observed in members of the genus <i>Geissleria</i>. This new taxon resembles<i> G. lubilensis</i> and<i> G. fogedii</i> in having a slightly triundulate margin but differs in their broad and protracted valve apices, holding differences from the new species.
