Actinella comperei sp. nov. is described from Clarence Lagoon, an oligotrophic lake in the Tasmanian highlands (Australia). Its frustule morphology, as studied in light and scanning electron microscopy, is compared with that of other recently described Actinella species from Australasia. Actinella comperei differs from other Actinella species in valve shape, stria density and rimoportula arrangement. As most other species described from Australasia, A. comperei appears to be endemic to this region. Moreover, within Tasmania it has hitherto only been found in Clarence Lagoon, which holds several diatom species endemic to Tasmania, and at least one other species endemic to the lake (Biremis clarensis).
