Abstract
The European leaf-toed gecko (Euleptes europaea) is a small, nocturnal gecko endemic to the western Mediterranean. As a phylogenetically distinctive member of the Gondwanan family Sphaerodactylidae, it represents an important species for studying Mediterranean island biogeography, adaptation, and reptile genome evolution. The species also occupies a key position for investigating the evolution of sex chromosomes, as geckos exhibit remarkable diversity and frequent transitions in sex-determination systems. We present a chromosome-level genome assembly of Euleptes europaea generated as part of the Vertebrate Genomes Project. The 1.8 Gb assembly has a scaffold N50 of 102.3 Mb (contig N50 27 Mb), with 21 chromosome-scale scaffolds corresponding to the known karyotype (2n = 42). The primary assembly has a BUSCO completeness of 97.80% (95.60% as single-copy), a k-mer completeness of 96.00%, and a k-mer quality value (QV) of 61.20. Repetitive elements account for 53.20% of the genome and genome annotation identified 18,633 protein-coding genes. This high-quality reference genome will facilitate studies of genome evolution, island adaptation, and sex chromosome evolution across geckos and other reptiles.
