There is another species (Artemidorus sobrinus) in Singapore that looks very similar to Artemidorus pressus based on the images in the iNaturalist website. As of 24 March 2025, there were 19 observations of Artemidorus sobrinus and 47 observations of Artemidorus pressus reported in the website. I am not able to differentiate the two.
