Diagnosis. Body small sized, about 2.2 mm, strongly chitinized, laterally compressed. Rostrum short, minute. Cephalic lobe rounded. Eye medium, subcircular, composed of numerous ommatidia. Pereonites and pleonites dorsally smooth. Antennae 1, 2 short, as long as head and pereonites 1, 2 combined. Gnathopods 1, 2 subchelate, similar to each other; palm oblique, defined by 4 spines. Pereopods 3, 4 similar to each other in size and form, except coxa 4 more concave posteriorly. Coxa 5 enlarged. Pereopods 3­6, dactylus shorter than propodus. Urosomite 1 with rounded dorsal carination which is slightly extending backward above following urosomite. Urosomites 2, 3 coalesced, with a pair of 3 or 4 dorsal spines in dorsal view. Telson deeply cleft.

Remarks. The shape of the dorsal process of urosomite 1 is a unique and characteristic feature for the genus Guernea . Our female specimen is in good agreement with the original description of Hirayama (1985), as it pertains to urosomite 1.
