AbstractThe formation of the Isthmus of Panama and final closure of the Central American Seaway (CAS) provides an independent calibration point for examining the rate of DNA substitutions. This vicariant event has been widely used to estimate the substitution rate across mitochondrial genomes and to date evolutionary events in other taxonomic groups. Nuclear sequence data is increasingly being used to complement mitochondrial datasets for phylogenetic and evolutionary investigations; these studies would benefit from information regarding the rate and pattern of DNA substitutions derived from the nuclear genome. To estimate this genomewide neutral mutation rate (μ), genotype-by-sequencing (GBS) datasets were generated for three transisthmian species pairs in Alpheus snapping shrimp. Using a Bayesian coalescent approach (G-PhoCS) applied to 44,960 GBS loci, we estimated μ to be 2.64E-9 substitutions/site/year, when calibrated with the closure of the CAS at 3 Ma. This estimate is remarkably similar to experimentally derived mutation rates in model arthropod systems, strengthening the argument for a recent closure of the CAS. To our knowledge this is the first use of transisthmian species pairs to calibrate the rate of molecular evolution from GBS data.

We review the taxonomy of sponge-dwelling shrimp in the “Gambarelloides species group” within the genus Synalpheus Bate 1888, an informal but widely recognized group that is largely endemic to the western Atlantic and contains the majority of Synalpheus species in that region. The validity of most species described from the western Atlantic is reevaluated based on extensive new material from Carrie Bow Cay, Belize, and on examination of types of most described species. Twenty-eight species, including all those historically considered as part of the Gambarelloides group, are herein removed from Synalpheus and transferred to Zuzalpheus, n. gen., which is diagnosed by two synapomorphies: the dense brush of curved setae on the minor first pereopod, and the mesial lamellae on the coxae of the 3 rd pereopods. Six new species are described (Zuzalpheus dardeaui, Z. elizabethae, Z. idios, Z. kensleyi, Z. ul, Z. yano) and Z. osburni (Schmitt 1933) n. comb. is removed from synonymy with Synalpheus goodei. An identification key to all 34 species of West Atlantic Zuzalpheus is presented, as are known host associations, and color plates of most species.
