Abstract
BACKGROUND: A total of seven known Indopadilla species are known from Vietnam: I.abramovi Logunov, 2024; I.annamita (Simon, 1903); I.cuc Wang, Li & Pham, 2023; I.phantoani Hoang & Zhang, 2023; I.retsivn Hoang, Phan & Vo, 2024; I.yokdon Hoang, Phan & Vo, 2024; and I.namkarensis Hoang, 2025. Amongst these, I.yokdon was previously known only from the female holotype collected in Yok Don National Park, Buon Don District, Dak Lak Province, Vietnam. In contrast, the remaining species were described, based on both male and female specimens. In the present study, the male of I.yokdon is described for the first time and the females are re-described, based on additional material collected from Dak Nong and Son La Provinces, Vietnam. NEW INFORMATION: Our surveys yielded records of three individuals of Indopadillayokdon from two localities: one male and one female from Son La Province and one female from Dak Nong Province. This paper provides a first detailed description of the male and a re-description of the female. A morphological comparison between the sexes is also presented to support future taxonomic and phylogenetic studies. Additionally, the record from Son La Province extends the known distribution range of the species.
