Chromosome-level genome assembly of the jumping spider Spartaeus platnicki.

Jumping spiders, a diverse and charismatic group of invertebrates, are renowned for their highly specialized visual systems, complex courtship behaviours, and broad ecological adaptability. However, the persistent lack of high-quality genomic resources has hindered investigations into the genetic basis and phenotypic evolution of these key traits. To address this gap, we performed a de novo assembly of a chromosome-level genome for Spartaeus platnicki, a species representing the basal lineages of jumping spiders. This assembly, achieved by integrating PacBio HiFi long reads, Illumina short reads, RNA-seq, and Hi-C data, comprises 15 pseudo-chromosomes including the X1 and X2 sex chromosomes, spanning a total length of 3.71 Gb with a scaffold N50 of 262 Mb and a BUSCO completeness of 98.60%. Repetitive elements account for approximately 65.57% of the genome. We annotated 15,660 protein-coding genes, achieving a BUSCO completeness of 97.60%. This high-quality genome establishes a foundational resource for investigating the genetic architecture underlying key traits and their phenotypic evolution in jumping spiders.
