(from Tawu, Taitung)(from Tawu, Taitung)

(from Lanyu, Taitung)

註: 由於大武澤蟹 (Geothelphusa tawu)、蘭嶼澤蟹  (G. lanyu Shy, Ng & Yu, 1994)、綠島澤蟹  (G. lutao Shy, Ng & Yu, 1994) 三者共享類似的形態特徵，且分子證據無法支持三個單系群 (Shih et al. 2023)，因此 WoRMS (https://www.marinespecies.org/aphia.php?p=taxdetails&id=443086) 已將後兩者處理為 G. tawu 的同物異名。

Note: As Geothelphusa tawu, G. lanyu Shy, Ng & Yu, 1994, and G. lutao Shy, Ng & Yu, 1994 share similar morphological characters, and molecular evidence cannot support three distinct clades (Shih et al. 2023), WoRMS (https://www.marinespecies.org/aphia.php?p=taxdetails&id=443086) has treated the later two species as synonyms of G. tawu.
