  abstract = {{A}im {G}eographical gradients of vertebrate species richness are determined jointly by evolutionary and environmental factors. {S}upport for these factors comes mostly from tetrapods and, recently, marine fishes, but their validity and relative importance in freshwater fishes is not well understood. {H}ere, we describe the species richness gradient for the major component of the viviparous freshwater fishes of the {A}mericas, the poeciliids, and test the effects of evolutionary and environmental factors on this pattern. {L}ocation {T}he {A}mericas. {T}ime period {A}pproximatley 56-0 {M}a. {M}ajor taxa studied {P}oeciliidae ({T}eleostei: {C}yprinodontiformes). {M}ethods {W}e constructed geographical ranges for 93% (256) of poeciliids to describe and evaluate their species richness gradient. {E}volutionary factors (evolutionary time and speciation rate) were derived from a recent phylogeny. {E}nvironmental factors were represented as basin area, topographical heterogeneity, energy, climate seasonality and past climatic stability. {W}e tested the influence of these factors with a piecewise structural equation model (p{SEM}). {R}esults {T}he distribution of {P}oeciliidae is biased to the {A}tlantic coast, with species richness showing a bimodal latitudinal gradient, peaking in middle latitudes near the {T}ropics of {C}ancer and {C}apricorn, and exhibiting the highest richness in {M}iddle {A}merica. {T}he p{SEM} showed that this species richness pattern was influenced positively by evolutionary time and past climatic stability and negatively by climate seasonality. {M}ain conclusion {T}he species richness gradient of {P}oeciliidae has been shaped by the interplay of evolutionary time in addition to current and historical climate. {I}ndeed, regions with high poeciliid richness were those containing by ancient lineages, supporting the time-for-speciation effect, and that have experienced low historical stability in temperature and currently show low temperature seasonality. {C}onversely, species-poor regions contained younger lineages and experienced greater temperature seasonality. {O}ur study highlights the need to assess jointly the evolutionary, historical and climatic drivers of species richness in order to unravel the causes of diversity gradients.},
