  abstract = {{T}he {T}ropical {I}ndo-{P}acific ({TIP}) includes about two thirds of the world's tropical oceans and harbors an enormous number of marine species. {T}he distributions of those species within the region is affected by habitat discontinuities and oceanographic features. {A}s well as many smaller ones, the {TIP} contains seven large recognized biogeographic barriers that separate the {R}ed {S}ea and {I}ndian {O}cean, the {I}ndian from the {P}acific {O}cean, the central and eastern {P}acific, the {H}awaiian archipelago, the {M}arquesas and {E}aster {I}slands. {W}e examined the genetic structuring of populations of {C}irrhitichthys oxycephalus, a small cryptic species of reef fish, across its geographic range, which spans the longitudinal limits of the {TIP}. {W}e assessed geographic variation in the mitochondrial cytb gene and the nuclear {RAG}1 gene, using 166 samples collected in 46 localities from the western to eastern edges of the {TIP}. {S}equences from cytb show three well-structured groups that are separated by large genetic distances (1.58-2.96%): two in the {T}ropical {E}astern {P}acific ({TEP}), one at {C}lipperton {A}toll another occupying the rest of that region and the third that ranges across the remainder of the {TIP}, from the central {P}acific to the {R}ed {S}ea and {S}outh {A}frica. {T}hese results indicate that the similar to 4,000 km wide {E}astern {P}acific {B}arrier between the central and eastern {P}acific is an efficient barrier separating the two main groups. {F}urther, the similar to 950 km of open ocean that isolates {C}lipperton {A}toll from the rest of the {TEP} is also an effective barrier. {C}ontrary to many other cases, various major and minor barriers from the {C}entral {I}ndo-{P}acific to the {R}ed {S}ea are not effective against dispersal by {C}. oxycephalus, although this species has not colonized the {H}awiian islands and {E}aster {I}sland. {T}he nuclear gene partially supports the genetic structure evident in cytb, although all haplotypes are geographically mixed.},
