Notes
Geosesarma ambawang and Geosesarma pontianak are very similar but differ in biological features.
Eye color:
- Geosesarma pontianak → deep yellow eyes
- Geosesarma ambawang → light, white eyes
Carapace shape:
- Geosesarma ambawang → proportionally wider carapace
- Geosesarma pontianak → more square-shaped carapace and longer, slimmer legs
Due to their similarity and close geographic range, Geosesarma ambawang is often mistakenly labeled as Geosesarma nothophorum or Geosesarma pontianak.
It is probably available in trade but difficult to distinguish from closely related species.
May be mixed with other species.
