Mitochondrial genomic sequences were assembled de novo from Illumina paired-end reads … See more

Briefly, we defined nuclear genes based on the gene model coordinates defined in SpBase Build 6 based on the Spur v3.1 genome assembly (SpBase.org). The alignments … See more

We created a concatenated alignment from the Gblocks masked alignments of mitochondrial genes (“MA”) and a concatenated alignment of mitochondrial genes fro… See more

We used two main approaches to reconstruct the phylogeny of the group using mitochondrial and nuclear genes. The first was a support-based method, which evaluated t… See more

To determine if there were significant differences between two proposed trees given the data, we performed the SH test using RELL bootstrap with 1000 replicates and the HK… See more

A strict molecular-clock was tested against a non-clock model assuming a nucleotide substitution model with gamma-distributed rate variation across sites and a proportion of sites inv… See more
