Description

Amphidromus atricallosus is a large land snail belonging to the family Camaenidae. One subspecies is confirmed to exist in Peninsular Malaysia, namely Amphidromus atricallosus perakensis. Another subspecies tentatively known to occur in Johor, and confirmed to occur in Singapore is Amphidromus atricallosus temasek.  For A. a. perakensis, dimorphic coiling exists within the populations in Peninsular Malaysia, with dextral and sinistral individuals. The snail shell is lemon yellow with white sub-sutural line running throughout it and has a twisted columella that sometimes develops into a columellar plate. It has a tall spire. This subspecies is widespread in Peninsular Malaysia (Foon et al., 2017). Meanwhile, A. a. temasek has a shell with a straight columella, is thinner and has deeper shade of yellow. This subspecies needs further research to verify its distribution in Peninsular Malaysia (Tan et al., 2011).
