Remarks. Ngankeecaris dardanicola comb. nov. represents the unique dwelling in association with sea anemones attached on gastropod shells occupied by hermit crabs of the genus Dardanus Paul'son, 1875 ( Bruce & Okuno 2006). The specimen from Okinawa ( Fig. 2 View FIGURE 2 ) was picked up on board the Teruyuki-maru, a commercial gillnet fishing vessel. Therefore, the host animals of the present specimen could not be determined.

Ngankeecaris dardanicola comb. nov. is readily distinguished from it congener, N. acanthimera comb. nov., by the following key.
