A new species of orb-weaver genus Argiope Audouin, 1826 from West Kalimantan, Indonesia, with notes on a new synonymy of Gea spinipes C. L. Koch, 1843 (Araneae: Araneidae)

Recent biodiversity expeditions in Danau Sentarum National Park and Betung Kerihun National Park, West Kalimantan, Indonesia have yielded significant findings in the genus Argiope Audouin, 1826. We described Argiope songketica sp. nov. (♂, ♀) and provided detailed descriptions with high-quality photographs of both sexes.

Additionally, we report the first record of Argiope versicolor (Doleschall, 1859) and Gea spinipes C. L. Koch, 1843 in the National Parks, extending their known distribution range. Finally, we propose Argiope sapoa Barrion & Litsinger, 1995 as junior synonym of Gea spinipes C. L. Koch, 1843. These findings highlight the arachnological significance of protected areas in Borneo and contribute to the knowledge of Southeast Asian araneids.
