in the red algae family, Entwisleiaceae. There is just one species (the type species) in this genus, ''Entwisleia bella'', from south-eastern Tasmania and represents both a new family and a new order in the Nemaliophycidae. It is a marine species found in the Derwent River estuary. It grows at depths between 5.0 and 9.0 m and is found scattered on mudstone reef flats dusted or shallowly covered by sand. The site at which it was found is subject to episodic high-rainfall events throughout the year and heavy swells in winter. It is a feathery dioecious seaweed, very like the freshwater red algae, '' Batrachospermum,'' but from DNA sequencing, appears to be quite unrelated. Scott ''et al.'''s (2013) study shows it as a sister clade of the Colaconematales. The genus was named to honour Tim Entwisle, was
