First genome assembly of the order Strepsiptera using PacBio HiFi reads reveals a miniature genome.

ABSTRACT: Twisted-wing insects (Strepsiptera) are an enigmatic order of parasites with unusual life histories and striking sexual dimorphism. Males emerge from hosts as free-living winged adults, while females from most species remain as endoparasites that retain larval traits. Due to scarce genomic data and phylogenetic controversies, Strepsiptera was only recently placed as the closest living relative to beetles (Coleoptera). Here, we report the first PacBio HiFi genome assembly of the strepsipteran Xenos peckii (Xenidae). This de novo assembly size is 72.1 Mb, with a BUSCO score of 87.4%, N50 of 7.3 Mb, 23.4% GC content, and 38.41% repeat content. We identified 8 contigs that contain >75% of the assembly and reflect the haploid chromosome number reported from karyotypic data, and 3 contigs that e
