The generic name, Garthius, is in honor of British herpetologist Garth Underwood.
The specific name, chaseni, is in honor of Frederick Nutter Chasen, who in 1931 was Curator of the Raffles Museum, Singapore.Beolens, Bo; Watkins, Michael; Grayson, Michael (2011). The Eponym Dictionary of Reptiles. Baltimore: Johns Hopkins University Press. xiii + 296 pp. {{ISBN|978-1-4214-0135-5}}. (Garthius chaseni, p. 52; Pit-viper genus Garthius, p. 98).

G. chaseni is heavy-bodied, and may attain {{convert|65|cm|in|frac=4|abbr=on}} SVL (snout–vent length). Dorsally, it has a dark tan or reddish brown ground color, overlaid by dark brown crossbands, which are broken and alternating on the front part of the body, becoming regular on the posterior part. Ventrally, it is yellow and gray. It has two rows of small scales between the upper labials and the eye.Das, Indraneil (2006). A Photographic Guide to Snakes and other Reptiles of Borneo.
