ABSTRACT
The lesser marbled fritillary, Brenthis ino (Rottemburg, 1775), is a species of Palearctic butterfly. Male Brenthis ino individuals have been reported to have between 12 and 14 pairs of chromosomes, a much-reduced chromosome number than is typical in butterflies. Here, we present a chromosome-level genome assembly for Brenthis ino, as well as gene and transposable element annotations. The assembly is 411.8 Mb in length with a contig N50 of 9.6 Mb and a scaffold N50 of 29.5 Mb. We also show evidence that the male individual from which we generated HiC data was heterozygous for a neo-Z chromosome, consistent with inheriting 14 chromosomes from one parent and 13 from the other. This genome assembly will be a valuable resource for studying chromosome evolution in Lepidoptera, as well as for comparative and population genomics more generally.
