Abstract:
Yucca moths (Prodoxidae) have long been considered by taxonomists to be basally positioned within the Lepidoptera in the superfamily Adeloidea. Recently, phylogenomic reconstructions of ordinal lepidopteran relationships using transcriptome data confirmed the basal position of the Adeloidea and the positioning of the Tegeticula pollinating yucca moths within the superfamily. However, to date, no phylogenetic studies have been conducted attempting to position the Prodoxus bogus yucca moths using whole genome data. We incorporated our own transcriptome libraries into publicly available lepidopteran data in order to phylogenetically confirm the evolutionary position of the Prodoxidae within the Lepidoptera and to assess the position of Prodoxus relative to Tegeticula. Our phylotranscriptomic reconstruction verified the Prodoxidae as the sister taxa to the basal Adelidae (Adeloidea), and Prodoxus as sister to Tegeticula. However, topological relationships among our four focal Tegeticula species contradicted recent findings from RAD-seq analyses. We show that this apparent paradox is in fact an artefact of the phylogenetic methods employed in building the ordinal level phylogeny (i.e. sequence alignment based on the first two nucleotide positions only) and that the true Tegeticula relationships are recovered by using all three nucleotide base positions to correctly infer more recent evolutionary events. Our work shows the utility of next-generation sequencing (NGS) technologies whilst highlighting some technical considerations that may confound phylogenetic interpretation according to taxonomic scale. We add to the growing consensus that NGS techniques offer a prime opportunity to elucidate previously challenging questions in evolutionary biology.
