Abstract

Status survey of the cave scorpion, Chaerilus chubluk Lourenço, Tran & Pham, 2020 was carried out in a volcanic cave, in Krong No district, Dak Nong province in 2022 and 2023. A total of 43 individuals were recorded, 25 individuals were recorded in the year 2022 and 18 individuals were recorded in the year 2023. This species is only known from Co Cave which is now strongly threatened by human impact. Based on the current area of occupancy (AOO) and extent of occurrence (EOO) of Chaerilus chubluk, associated with its recent regression in both AOO and number of individuals, this species is tentatively classified as critically endangered by IUCN. The research results are presented for the first time, as scientific data for the conservation of this scorpion and integrated into the IUCN database.
