CommentHabitat: arboreal, in broad-leaf forest at elevation between 1 800–2 200 m a.s.l. (Figure 1 in Wang et al. 2019). Individuals were observed foraging both on trees and on the ground during the day, but only resting on twigs or thin stems of bushes at night from about 1 m to 2–3 m above ground. D. swild inhabits the moister, montane area that is further away from the much dryer main course of the Jinsha River, where D. dymondi lives. 
EtymologyThe specific name "swild", which is a noun, is derived from the name of the Chinese Conservation Organization, Swild Studio ( 西 南 山 地 工 作 室). We name the species after the organization in honoring its continuous contributions on promoting citizen science, nature photography, and public outreach on the wildlife conservation in Southwest China, particularly in the Hengduan Mountain Regions where the new species is native.
