The circumscription of one previously published species, P. sarasinii (Däniker) G.L.Nesom, is discussed and updated, and P. neocaledonica (Guillaumin) G.L.Nesom is placed in its synonymy. The name P. comptonii Gâteblé, Lannuzel & M.Pignal, nom. nov. is proposed to accommodate the former Lagenophora neocaledonica S.Moore in Pytinicarpa, and its lectotype is designated. Two new narrowly endemic species are also described. The first is from the top of Mount Kaala massif with the name P. kaalaensis Lannuzel, Gâteblé & M.Pignal, sp. nov. The second, P. tonitrui Lannuzel, Gateblé & M.Pignal, sp. nov. is from the Babouillat peninsula, and is supposedly extinct, as extensive field research did not allow to find it. The four species are fully described, illustrated, and keyed. The distribution, ecological affinities, and threats for the four species are discussed to support the assessments of conservation status for two of them as Endangered (EN), one as Critically Endangered (CR) and one as Extinct (EX), following the IUCN Red List guidelines and criteria.
