  abstract = {{I}n the past few decades, in the marine realm in particular, the use of molecular tools has led to the discovery of hidden taxonomic diversity, revealing complexes of sister species. {A} good example is the red algal genus {A}sparagopsis. {T}he two species ({A}. armata and {A}. taxiformis) recognized in this genus have been introduced in many places around the world. {W}ithin the nominal species {A}. taxiformis, previous molecular analyses have uncovered several lineages, suggesting the existence of sister species or subspecies. {A}lthough the genus has been well studied in some regions (e.g., the {M}editerranean {S}ea and {H}awaii), it remains poorly investigated in others (e.g., {S}outh {P}acific). {O}ur study mainly focused on these latter areas to clarify lineages and better determine lineage status (i.e., native vs. introduced). {A} total of 188 specimens were collected from 61 sites, 58 of which had never been sampled before. {W}e sequenced the {DNA} from samples for three markers and obtained 112 sequences for the chloroplastic {R}u{B}is{C}o spacer, 118 sequences for the nuclear {LSU} r{RNA} gene, and 174 for the mitochondrial spacer cox2-3. {P}hylogenetic analyses using all three markers suggested the existence of two cryptic sister species with the discovery of a new clade within {A}. armata. {T}his clade was found only in {W}estern {A}ustralia, {T}asmania and {N}ew {Z}ealand, and is thus restricted to a subregional biogeographic unit. {W}e also discovered a new, fifth lineage for {A}. taxiformis restricted to the {S}outh {P}acific and {W}estern {A}ustralia. {E}xcept for this newly described lineage, all other lineages showed a global distribution influenced by introduction events. {T}hese results illustrate the difficulty in accurately defining cosmopolitan species. {O}ur findings also highlight the need for targeted (i.e., in poorly studied areas) and geographically extensive sampling efforts when studying taxa that have been introduced globally and that are likely to hide species complexes.},
