Chromosome-level genome assembly of the caddisfly Stenopsyche angustata (Insecta: Trichoptera)

Stenopsyche angustata, a species within the diverse order Trichoptera, is widely distributed across freshwater environments and exhibits unique ecological traits that make it an ideal subject for studying adaptive evolution. In this study, we employed Illumina second-generation sequencing, PacBio third-generation sequencing, along with high-throughput chromosome conformation capture (Hi-C) technologies to generate raw sequencing data and construct chromosome-level genome assemblies of S. angustata. The final genome assembly size was 510.47 Mb, with scaffold N50 length of 39.81 Mb. The genome was successfully anchored to 13 pseudochromosomes, and a total of 10,699 protein-coding genes were identified. The genome contained 44.92% repeat sequences and 1,004 non-coding RNAs. Moreover, a total of 10,699 protein-encoding genes were predicted, representing 97.7% of the total genes. This comprehensive genomic analysis unveil crucial details about the genetic makeup of S. angustata, providing a foundation for understanding of the evolutionary processes and ecological functions of this species.
