摘要

Ants, one of the most representative groups among invertebrates, exhibit a typical latitudinal diversity gradient, with a rich variety of species. The genus Myrmica Latreille, 1804 is a species-rich (over 200 species) group within the Myrmicinae and mainly distributed in the Holarctic region, making it a good model for biogeography and adaptive evolution analysis. To this end, we present a chromosome-level genome of Myrmica angulata achieved through the integration of PacBio, Illumina, and Hi-C reads. The assembled genome was 464.36 Mb whose 97.36% was anchored into 24 pseudochromosomes, with a contig N50 of 1.752 Mb, a scaffold N50 of 18.23 Mb, and 98.5% BUSCO completeness. It contained 248.99 Mb (53.62%) repeat sequences, 1,036 non-coding RNAs, and 17,066 protein-coding genes. The high-quality genome assembly of M. angulata lays the foundation for further exploration of the genetic mechanisms underlying their ecological adaptation to high-latitude and high-altitude environments, and provides a valuable reference for understanding the adaptive evolution of ants.
