Genome Annotation of the Biting Midges Culicoides sonorensis and Culicoides stellifer Generated Using the EGAPx-alpha Pipeline

This collection contains gene annotation datasets for Culicoides sonorensis and Culicoides stellifer (Diptera: Ceratopogonidae), two biting midge species of veterinary significance. Culicoides sonorensis is a confirmed vector of Bluetongue and Epizootic Hemorrhagic Disease viruses in North America, while C. stellifer has been implicated in Orbivirus transmission in the southeastern United States. The reference genome assemblies for these species are publicly available at NCBI under accession numbers GCA_047716325.1 (C. sonorensis) and GCA_040583785.1 (C. stellifer).

Gene models for both assemblies were predicted using the EGAPx-alpha pipeline (egapx:0.3.2-alpha), employing the same C. sonorensis RNA-Seq dataset (ERR2171964 – ERR2171978) as transcriptomic evidence for model training, as no C. stellifer RNA-Seq data are currently available (Last checked- 17/11/2025). The dataset includes gene model coordinates (GFF), transcript nucleotide sequences (FNA), and predicted protein sequences (FAA).

These curated annotation datasets were generated to support the forthcoming manuscript: Chromosome-scale genome of Culicoides brevitarsis highlights genetic basis of vector competency. They provide consistent annotation resources for cross-species comparative analyses among Culicoides midges.
