( Figs. 133-136 View Figure 86-152 )
Valves heteropolar, lanceolate, slightly linear. Apical ends cuneate, and basal ends attenuate-rounded. 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 G. rhombicum Fricke from Metzeltin et al. (2005), concerning valve shape and striae pattern. Besides that, G. rhombicum has a stigma and cuneate-rounded ends.
