A new Gomphonema species is described from the Shiwan Mts. in Guangxi Zhuang Autonomous Region, Southwest China. This new species differs from other known members of the genus Gomphonema by its linear-lanceolate shape, wide axial area, slit-like areolae openings, one short spine at the headpole externally, and large pseudoseptum at each end internally. Morphological features of the new species are detailed with light and scanning electron microscopy. Comparisons with other similar species are made. This species appears to be closely related to other species of this genus possessing wide axial areas.
