The arboreal land snail of the genus Amphidromus Albers, 1850, found in Singapore is often identiﬁ ed in the literature as Amphidromus atricallosus perakensis Fulton, 1901. Studies of A. atricallosus perakensis material from various localities in Peninsular Malaysia showed that the Singapore population is distinct. Results from earlier studies on molecular phylogeny and allozyme analyses also suggest genetic discontinuity from other A. atricallosus subspecies. The Singapore population is herein described as A. atricallosus temasek, new subspecies, and can be differentiated from A. atricallosus perakensis by several morphological characters.
