Notes:
Geosesarma ambawang and Geosesarma pontianak are very similar and differ in biological traits.
The most noticeable external features are the eye color: Geosesarma pontianak has very yellow eyes, while Geosesarma ambawang has lighter, almost white eyes. Additionally, Geosesarma ambawang has a proportionally wider carapace compared to Geosesarma pontianak. Geosesarma pontianak has a more square-shaped carapace and longer, more slender legs.
Due to their similarity, proximity in location, and the occasional misidentification as Geosesarma nothophorum, it is difficult to distinguish this species from closely related ones such as Geosesarma ambawang and Geosesarma nothophorum. It is likely that they are mixed in the trade.
