A new species of the rare caridean genus Bresilia Calman, 1896, B. gibbosa, is described and illustrated on the basis of one ovigerous female and one male specimens collected from a shallow water marine cave in Okinawa Island, Ryukyu Islands, Japan. The new species is morphologically similar to B. antipodarum Bruce, 1990, B. briankensleyi Bruce, 2005, B. plumifera Bruce, 1990 and B. saldanhai Calado, Chevaldonne & dos Santos, 2004 in the strongly produced third abdominal tergite, the presence of a long epistomal process, and the presence of an exopodal flagellum on the first maxilliped, but is easily distinguished from all these allied species by the possession of movable spines in the dorsal rostral series and the angular, instead of spinose, pterygostomial margin of the carapace. This new species is the first representative of Bresiliidae from the North Pacific Ocean.
