Abstract: Museomics is a valuable approach that utilizes the diverse biobanks that are natural history museums. The ability to sequence genomes from old specimens has expanded not only the variety of interesting taxa available to study but also the scope of questions that can be investigated in order to further knowledge about biodiversity. Here, we present whole genome sequencing results from the enigmatic genus Whalleyana (comprising two species - occurring in drier biomes of Madagascar - previously placed in a monotypic superfamily, Whalleyanoidea), as well as from certain species of the families Callidulidae and Hyblaeidae (Calliduloidea and Hyblaeoidea, respectively). Library preparation was carried out on four museum specimens and one existing DNA extract and sequenced with Illumina short reads. De novo assembly resulted in highly fragmented genomes with the N50 ranging from 317 to 2078 bp. Mining of a manually curated gene set of 331 genes from these draft genomes had an overall gene recovery rate of 64-90%. Phylogenetic analysis places Whalleyana as sister to Callidulidae and Hyblaea as sister to Pyraloidea. Since the former sister-group relationship turns out to be also supported by ten morphological synapomorphies, we propose to formally assign the Whalleyanidae to the superfamily Calliduloidea. These results highlight the usefulness of not only museum specimens but also existing DNA extracts, for whole genome sequencing and gene mining for phylogenomic studies.
