Hawaiioscia
Hawaiioscia is a genus of woodlouse known from the Hawaii, Rapa Nui, and Costa Rica. The genus was originally described from Hawaii on the presence of four troglobitic species on separate islands. A species within this genus was then described from Rapa Nui which lacked troglobtic traits, but only persists in cave-dwelling relict populations. Surprisingly, another species was then described from along the Pacific Coast of Costa Rica.
