  abstract = {{A} new tropical genus and species belonging to the family {D}icranemataceae, {P}innatiphycus menouana, is described from lagoon and outer reef-slope habitats in {N}ew {C}aledonia and {F}iji. {T}he new genus differs from other members of the family by the unique combination of the following characters: (1) tetrasporangia borne in terminal nemathecia on lateral cylindrical branchlets; and (2) the disposition of cystocarps along lateral branchlets rather than on the main axis itself. {T}he new species differs from {P}eltasta australis {J}. {A}gardh by the presence of cylindrical lateral branchlets along the flattened main axes and the occurrence of reproductive structures in terminal, subterminal or basal positions on the lateral branchlets. {I}t differs from subtropical {R}eptataxis rhizophora ({L}ucas) {K}raft from {L}ord {H}owe {I}sland by the presence of both yellowish refractive medullary cell clusters and cylindrical lateral branches bearing subapical tetrasporangial sori and cystocarps, as well as a central fusion cell and the production of carposporangia in chains of two to three rather than four to six. rbc{L} molecular analysis of {F}ijian samples unequivocally places the genus in the family {D}icranemataceae with 100% bootstrap support, strongly relating it to two species of {T}ylotus. {T}he family itself, however, received only weak bootstrap support (66%) for distinguishing it from the clade containing the virtually {A}ustralian-endemic families {M}ychodeaceae and {A}crotylaceae. {P}innatiphycus favors deepwater habitats (65-70 m) with low light intensities or shallower (< 30 m) but turbid high-current areas, which may have contributed to it being overlooked in the past.},
