Distribution map of the Pupina arula species group: Pupina peguensis (triangle), Pupina crosseana (plus sign), Pupina siamensis (circle), Pupina bilabiata sp. nov. (square), and Pupina godwinausteni sp. nov. (star). Each red symbol indicates the type locality of its respective taxon. The occurrences of Pupina arula and Pupina mouhoti in northern Thailand are uncertain, thus their distributions are not mapped.
