1. The unicellular marine red alga Erythrolobus australicus sp. nov. (Porphyridiophyceae) was isolated into laboratory culture from mangroves in Queensland and New South Wales, Australia.
2. The single multi-lobed red to rose-red plastid has more than one pyrenoid and lacks a peripheral thylakoid. Arrays of small electron dense globules occur along the thylakoids.
3. The nucleus is peripheral with a central to eccentric nucleolus. Each Golgi body is associated with a mitochondrion.
4. The spherical cells are positively phototactic with slow gliding movement.
5. The psa A + psb A phylogeny clearly showed that E. australicus is a distinct species, which is closely related to E. coxiae.
6. The chemotaxonomically relevant and most abundant low molecular weight carbohydrate in E. australicus is floridoside.
7. Traces of digeneaside were also detected.
