Length of sexually mature specimens 5-9 mm. 



The body is smooth. The head has dorsal keels running from the 

 place of attachment of antennae I and large spines on the sides below the 

 167 place of attachment of antennae I. The eyes are very small. Antennae I 

 are the same length as the pereon and pleon together. 



The mouth cone is small; the outer lobes of the maxillipeds are 

 oblong-oval, slightly tapering distally, and the inner lobes very small 

 and not armed. 



All the pereopods are unusually thin and long. Pereopods I are 

 shorter than the rest, their segments thin; even the 5th segment is not 

 broadened distally, is very slightly shorter than the 2nd, and 1.5 times 

 longer than the 6th; the claw is long and broad. In pereopods II the 

 5th and 6th segments are almost equal in length. Pereopods III and IV 

 are similar in structure; they differ from the corresponding structures of 

 other species of the Scina by an unusually long 4th segment which is
