本文报道了采自日本冲绳东海岸滩涂的两种海鲶。据报道，Ceradocus mizani Lim，Azman & Othman，2010的范围扩大。在Hughes & Lowry（2011）中描述了Elasmopus mukuinu sp. nov.，并且与Elasmopus pectenicrus（Bate，1862）组中的物种最相似。该新种与其他种的区别在于，第2节前足动物在趾插入处附近有一个近矩形的隆起，前足动物被密集的长刚毛丛覆盖，第5、6和7节前足动物的后缘（分别几乎光滑、锯齿和细齿）。
Two species of Maeridae are reported from extensive tidal flat collections on the east coast of Okinawa Island, Japan. A range extension is reported for Ceradocus mizani Lim, Azman & Othman, 2010. Elasmopus mukuinu sp. nov. is described and is most similar to species in the Elasmopus pectenicrus (Bate, 1862) group in Hughes & Lowry (2011). The new species is distinguished from other species based on the gnathopod 2 propodus bearing a subrectangular hump near insertion of the dactylus, the propodus being covered in dense tufts of long setae and the posterior margins of pereopods 5, 6, and 7 (almost smooth, serrate, and crenulate, respectively).
