Axial are lanceolate, central area rectangular limited by a shortened striae. Raphe straight, with proximal ends, slightly dilated to pores. Striae short, parallel to slightly radiate toward the ends. Stigma absent. Length: 16.4 - 25 μm; width: 3.5 - 4.1 μm; striae 13 - 15 in 10 μm. The specimens observed are morphologically similar to <i>G. rhombicum</i> Fricke from Metzeltin <i>et al.</i> (2005), concerning valve shape and striae pattern. Besides that, <i>G. rhombicum</i> has a stigma and cuneate-rounded ends.</p><p><b>Material examined:</b> BRAZIL, MATO GROSSO DO SUL: Batayporã, Garças Lake, 21.IX.2017, sediment, D.T.
