摘要

The family Scarabaeidae is one of the largest and most ecologically significant groups within the order Coleoptera, comprising over 35,000 described species. However, the limited availability of high-quality genome assemblies has hindered comprehensive studies on their ecology and evolutionary biology. In this study, we present a high-quality, chromosome-level genome assembly of Kibakoganea sinica, generated by integrating PacBio HiFi, Illumina, and Hi-C sequencing data. The final assembly spans 601.44 Mb, comprising 23 scaffolds (scaffold N50: 60.23 Mb) and 70 contigs (contig N50: 24.49 Mb), with 99.57% of the total assembly (598.84 Mb) successfully anchored to 10 chromosomes. BUSCO analysis (n = 1,367) indicates a high level of completeness, with 99.2% of genes detected: 95.2% as single-copy and 4.0% as duplicated. Repetitive elements account for 44.43% (267.24 Mb) of the genome, and a total of 12,940 protein-coding genes were predicted. This chromosome-scale genome assembly provides a foundational resource for future research into the biology and adaptation of Scarabaeidae.
