Abstract
Megalaria crispisulcans A.J. Marshall, Blanchon & de Lange (Ramalinaceae) is described as a new species from populations in Te Ika a Māui / North Island of Aotearoa / New Zealand, and on Rēkohu / Wharekauri / Chatham Island, Aotearoa / New Zealand. The new species is morphologically closely allied to Megalaria orokonuiana, from which it is distinguished by its nrDNA ITS sequence and morphologically by the usual presence of a white prothallus, bright green (when fresh) isidiate thallus and dark black apothecia, whose rims are usually crinkled / undulose at maturity. A phylogeny based on nrDNA ITS sequences is presented that recovers Megalaria crispisulcans as sister to M. orokonuiana. The ecology, habitats and conservation status of M. crispisulcans is provided and an update on the conservation status of M. orokonuiana provided. A revised key to the Aotearoa / New Zealand species of Megalaria is provided.
