Yet, current molecular biological resources for this species are limited. Here, we employ Hi-C sequencing to generate a greatly improved genome assembly and we annotate its repetitive elements in a dedicated in-depth effort where we manually curate and classify the most abundant unclassified repeat subfamilies. We present a scaffolded chromosome-level assembly, which is 1.01 Gb in total length with 86% being contained within the 9 autosomes and the X chromosome. Repetitive sequences accounted for 70% of the total assembly. DNA transposons covered 18% of the genome, with the most abundant superfamily being Tc1-Mariner (9.75% of the genome). This new chromosome-level genome assembly of C. maculatus will enable future genetic and evolutionary studies not only of this important species but of beetles more generally.", "doi": "10.1093/g3journal/jkad266", "pmid": "38092066", "labels": [], "xrefs": [{"db": "pmc", "key": "PMC10849321"}, {"db": "pii", "key": "7471854"}], "notes": [], "created": "2026-09-23T11:22:32.664Z", "modified": "2026-09-23T11:22:32.716Z"}
