An annotated chromosome-level genome of a troglophilic spider (Pimoa clavata)

Year: 2025

Type: data-paper

Abstract: Climatic upheavals throughout Earth's history have driven species to subterranean refugia, where stable microclimates buffer environmental extremes. The spider family Pimoidae, relict lineages sensitive to thermal fluctuations, exemplifies this climate-driven habitat transition. Here, we present the first chromosome-level genome of Pimoa clavata, a troglophilic spider endemic to Beijing's mountainous caves. Combining PacBio HiFi and Hi-C sequencing, we assembled a 1.94 Gb genome with 29 scaffolds in chromosomes level, which were further subjected to comprehensive annotation. The well-annotated genome of this species provides foundational insights into the genomic basis of subterranean adaptation, offering critical resources for evolutionary genomics and conservation of climate-vulnerable cave species.
