Length of sexually mature specimens 2-4 mm. 



The body is smooth and without keels. Antennae I are strong, equal 

 in length to the pereon or slightly shorter than it. The mouth cone is small. 

 The outer lobes of the maxillipeds are oblong-oval, slightly tapering 

 distaily; the inner lobes are short, with two apical setae. 



Pereopods I-IV are the same as in S. tullbergi but the 4th segment of 

 pereopods III-IV is relatively shorter. The 2nd segment of pereopods V 

 is armed on the posterior margin with long curved denticles, the anterior 

 margin of the segment is smooth, with one or two large denticles only at 

 the base of the short distal process; the 4th segment is slightly shorter than 

 the 2nd and roughly twice longer than the 5th, which in turn is somewhat
