Diagnosis

Monad, isopolar, radiosymmetric, tri- and occasionally tetracolporate (syncolporate), colpi long, straight, narrow, meeting at the poles, pores not seen but presumed to be elliptical and transverse; oblate, amb straight-sided to weakly concave with pointed to subround apices; exine b1 μm thick, columellae not visible, ±psilate to granulate or scabrate, 9–17 μm in maximum polar view. The equatorial diameter ranges from 9–17 μm
