The new combination Solenogyne christensenii (Petrie) de Lange, Jian Wang ter & Barkla comb. nov. is validated for a New Zealand species originally published as Abrotanella christensenii Petrie. The species is described, illustrated and differentiated from similar and related taxa. The species is seriously threatened, being known with certainty only from the South Island of New Zealand where there is one extant population in Otago, though the species was also known historically from the type locality, Hanmer Plain, North Canterbury.
