Data from: Multi-locus sequence data reveal a new species of coral reef goby (Teleostei: Gobiidae: Eviota), and evidence of Pliocene vicariance across the Coral Triangle

Luke Tornabene, Samantha Valdez, Mark V. Erdmann & Frank L. Pezold
Here, multi-locus sequence data are coupled with observations of live colouration to recognize a new species, Eviota punyit from the Coral Triangle, Indian Ocean and Red Sea. Relaxed molecular clock divergence time estimation indicates a Pliocene origin for the new species, and the current distribution of the new species and its sister species Eviota sebreei supports a scenario of vicariance across the Indo-Pacific Barrier, followed by subsequent range expansion and overlap in the Coral Triangle....

Data from: Genomic data reveal ancient microendemism in forest scorpions across the California Floristic Province

, Warren E. Savary, Amanda J. Zellmer, R. Bruce Bury, John E. McCormack & Robert W. Bryson
The California Floristic Province (CFP) in western North America is a globally significant biodiversity hotspot. Elucidating patterns of endemism and the historical drivers of this diversity has been an important challenge of comparative phylogeography for over two decades. We generated phylogenomic data using ddRADseq to examine genetic structure in Uroctonus forest scorpions, an ecologically restricted and dispersal-limited organism widely distributed across the CFP north to the Columbia River. We coupled our genetic data with species...

Data from: Angelfishes, paper tigers and the devilish taxonomy of the Centropyge flavissima complex

Joseph D. DiBattista, Michelle R. Gaither, Jean-Paul A. Hobbs, Luiz A. Rocha & Brian W. Bowen
The pygmy angelfishes (genus Centropyge) provide numerous examples of discordance between color morphology, taxonomy and evolutionary genetic lineages. This discordance is especially evident in the Centropyge flavissima complex, which includes three primary color morphs, three previously recognized species (C. flavissima, C. eibli and C. vrolikii) and three distinct mitochondrial (mtDNA) lineages that do not align with species designations. Our previous research showed that the putative C. flavissima arose independently in the Indian and Pacific Oceans,...

Data from: Taxonomic revision of the Malagasy Camponotus grandidieri and niveosetosus species groups (Hymenoptera, Formicidae) using qualitative and quantitative morphology

Jean Claude Rakotonirina, Sándor Csősz & Brian L. Fisher
The Camponotus grandidieri species group and Camponotus niveosetosus species group of the Malagasy region are revised. Species delimitation was inferred from the evidence of both qualitative morphological analysis and multivariate morphometry. The multivariate method combined the Nest Centroid (NC)-clustering method and Partitioning Algorithm based on Recursive Thresholding (PART) function to generate hypotheses about species boundaries (clusters) based on 19 continuous morphological traits of minor workers. The proposed species hypotheses were tested by cumulative cross-validated Linear...

Data from: Understanding past population dynamics: Bayesian coalescent-based modeling with covariates

Mandev S. Gill, Philippe Lemey, Shannon N. Bennett, Roman Biek & Marc A. Suchard
Effective population size characterizes the genetic variability in a population and is a parameter of paramount importance in population genetics and evolutionary biology. Kingman's coalescent process enables inference of past population dynamics directly from molecular sequence data, and researchers have developed a number of flexible coalescent-based models for Bayesian nonparametric estimation of the effective population size as a function of time. Major goals of demographic reconstruction include identifying driving factors of effective population size, and...

Data from: Mulloidichthys flavolineatus flavicaudus Fernandez-Silva & Randall subsp. n. (Perciformes: Mullidae), a new subspecies of goatfish from the Red Sea and Arabian Sea

Iria Fernandaz-Silva, John Randall, Daniel Golani, Sergey V. Bogorodsky, Iria Fernandez-Silva & John E. Randall
The number of goatfish sp­­ecies has increased recently, thanks in part to the application of molecular approaches to the taxonomy of a family with conservative morphology and widespread intraspecific color variation. A new subspecies Mulloidichthys flavolineatus flavicaudus Fernandez-Silva & Randall subsp. n. is described from the Red Sea and Arabian Sea, including Socotra and Gulf of Oman. The two subspecies are distinguished by 1.7% sequence divergence at the mitochondrial cytochrome b gene, a yellow caudal...

Data from: Spider phylogenomics: untangling the spider tree of life

Jason Bond, Nicole L. Garrison, Juanita Rodriguez, Ingi Agnarsson, Jonathan A. Coddington, Charles E. Griswold, Christopher A. Hamilton, Marshal Hedin, Kevin Kocot, Joel M. Ledford & Jason E. Bond
Spiders (Order Araneae) are massively abundant generalist arthropod predators that are found in nearly every ecosystem on the planet and have persisted for over 380 million years. Spiders have long served as evolutionary models for studying complex mating and web spinning behaviors, key innovation and adaptive radiation hypotheses, and have been inspiration for important theories like sexual selection by female choice. Unfortunately, past major attempts to reconstruct spider phylogeny typically employing the “usual suspect” genes...

Data from: Introgression and selection shaped the evolutionary history of sympatric sister-species of coral reef fishes (genus: Haemulon)

Moises A. Bernal, Michelle R. Gaither, Warren Brian Simison & Luiz A. Rocha
Closely related marine species with large sympatric ranges provide opportunities to study the mechanisms of speciation, particularly when there is evidence of gene flow between the lineages. Here we focus on a case of hybridization between the sympatric sister-species Haemulon maculicauda and H. flaviguttatum, using Sanger sequencing of mitochondrial and nuclear loci, as well as 2422 single nucleotide polymorphisms (SNPs) obtained via Restriction-site Associated DNA Sequencing (RADSeq). Mitochondrial markers revealed a shared haplotype for COI...
