A new species of the genus Icius (Araneae: Salticidae) from the Ogasawara Islands, Japan

Researchers have identified and described a new species of jumping spider, Icius rugosus, from the Ogasawara Islands, Japan. This discovery, published in Acta Arachnologica, distinguishes the species through unique genital morphologies and male chelicera with ventral wrinkles, setting it apart from the closely related I. hamatus. Additionally, the study synonymizes I. daisetsuzanus with Sitticus ranieri, clarifying the taxonomic status of Japanese species in this genus. The Ogasawara Islands serve as a critical biodiversity hotspot, underscoring the significance of this finding for understanding regional arachnid diversity.
