A new species of terrestrial potamid crab, Terrapotamon longitarsus, is described from limestone hills in Satun Province in southern Thailand. It is easily distinguished from other Terrapotamon species by its conspicuously long ambulatory legs (all congeners have proportionately short legs), relatively smooth dorsal surface of carapace, transversely narrow male thoracic sternites 1-4, and a characteristically structured male first gonopod.
一种新的陆栖相手蟹物种——长跗相手蟹(Terrapotamon longitarsus),在泰国南部沙敦府的石灰岩山中被发现并予以描述。它很容易与其他相手蟹物种区分开来,其显著特征是步足明显较长(所有同属物种的步足相对较短)、头胸甲背面相对光滑、雄蟹第1至第4胸腹甲横向狭窄,以及雄蟹第一交接器具有独特的结构。
