Distribution and Natural history notes. Gonyosoma iadinum sp. nov. inhabits a broad altitudinal range, from 655 to 1,780 m asl, and is found across diverse forest communities, where it is active usually during daylight hours. In Vietnam , Gonyosoma iadinum sp. nov. is currently known from the montane evergreen forests of the Kon Tum-Gia Lai Plateau in the Truong Son (Annamite) Mountains of central Vietnam , as well as the Langbian Plateau in southern Vietnam . Verified records include Chu Yang Sin NP) in Dak Lak Province (our data), where it was observed at an elevation of 1,200 m asl at 21:00, sleeping on a tangle of Gramineae grasses and Brainea insignis ferns overhanging a path along a river terrace at the boundary of a dry pine forest dominated by Pinus kesiya ; Hon Ba NR in Khanh Hoa Province (our data); and Ta Dung NP in Dak Nong Province (our data, David et al . 2022 ), where it was found at 1,780 m asl at 22:00, resting on lower branches in a foggy, evergreen, small-leaved polydominant forest at the summit of the narrow Ta Dung Mountain ridge. Additional confirmed records include Bidoup-Nui Ba NP and Di Linh District in Lam Dong Province ; Kon Chu Rang NR in Gia Lai Province ( David et al . 2022 ); Kon Plong District in Kon Tum Province ( David et al . 2022 ; our data); Ba Na-Nui Chua NR in Da Nang City ( David et al . 2022 ; our data); Bach Ma NP in Thua Thien-Hue Province (our data); and Song Thanh NP and Nam Giang District in Quang Nam Province (our data), where the species was found at elevations ranging from 655 to 1,550 m asl. Records from Quang Ngai , Binh Dinh , Phu Yen , Ninh Thuan , and Binh Thuan provinces in central and southern Vietnam are anticipated. In Bach Ma NP, Thua Thien-Hue Province , an individual was observed at 22:00 resting on a 2.5 m-high tree over a slow-flowing stream. In Ba Na-Nui Chua NR, Da Nang City, another specimen was encountered at 10:00 while it was actively moving across a road. In Laos (based on David et al . 2022 , 2023 ), Gonyosoma iadinum sp. nov. is definitively recorded from central and southern regions of the country. Verified occurrences include Khammouan Province (Hin Nam No National Protected Area) in central Laos and Champasak Province (Dong Hua Sao National Biodiversity Conservation Area, Bolaven Plateau, and an additional nearby locality on the same plateau) in southern Laos . Additional records from Salavan and Xekong provinces in southern Laos are anticipated. Stuart (1999) documented this species in wet evergreen forests of the Annamite Mountain Range. Furthermore, a specimen reported by Stuart & Heatwole (2008) from Champasak Province was found on a trail within a disturbed, humid evergreen forest at an elevation of 1,000 m asl.
