  abstract = {{F}ishes of the tropical {I}ndo-{P}acific family {S}iganidae comprise 28 species, characterized by their body proportions and their colour patterns. {A} mitochondrial phylogeny of 20 {S}iganidae species was produced to infer their evolutionary history. {T}hree distinct, major clades were found, that also correspond to the early radiation of the family into three major ecological types: fusiform species that also live in schools on the inshore reef flats ({S}. canaliculatus, {S}. fuscescens, {S}. luridus, {S}. rivulatus, {S}. spinus, {S}. sutor); deep-bodied species including brightly coloured ones whose adults live in pairs on the reef front ({S}. corallinus, {S}. doliatus, {S}. puellus, {S}. punctatus, {S}. unimaculatus, {S}. virgatus, {S}. vulpinus), and species that live in small schools in mangroves, estuaries and estuarine lakes ({S}. guttatus, {S}. javus, {S}. lineatus, {S}. randalli, {S}. vermiculatus); and a third clade including a cosmopolitan species, {S}. argenteus, the only species of the family known to possess a pelagic, prejuvenile stage and {S}. woodlandi, a recently described species from {N}ew {C}aledonia and morphologically close to {S}. argenteus. {T}he partition of the genus into two sub-genera, {L}-{O} (erected for {S}. unimaculatus, {S}. vulpinus and three related species possessing a tubular snout) and {S}iganus (all the other species), had no phylogenetic rationale. {T}he present results indicate that the tubular snout, which apparently results from ecological specialization, is a recent acquisition within the deep-body clade. {T}he {W}estern {I}ndian {O}cean endemic {S}. sutor appeared as the sister-species of the {R}ed {S}ea endemic {S}. rivulatus within a well-supported subclade that also included {S}. canaliculatus and {S}. fuscescens. {S}. spinus did not appear as sister-species to {S}. luridus. {S}. lineatus haplotypes formed a paraphyletic group with {S}. guttatus, and an early isolation of {M}aldives {S}. lineatus was suggested. {U}nexpectedly, {S}. randalli did not appear as the sister-species of {S}. vermiculatus, but its haplotypes instead were embedded within the {W}est {P}acific {S}. lineatus haplogroup, suggesting recent introgression. {A}mong currently-recognized sister-species with parapatric distribution, {S}. doliatus and {S}. virgatus haplotypes formed a single, unresolved haplogroup, as did {S}. unimaculatus and {S}. vulpinus. {T}he occurrence of two distinct clades within {S}. fuscescens was confirmed.},
