Male differs from L. kroyeri in several particulars. The posterior thoracic segment 

 in this variety is rounded at base, and has a trifid projection on the left side instead 

 of a bifid one as in L. kroyeri. The 1st abdominal segment has a long narrow spine 

 on its right basal corner. The end of basal portion of the claspers in the 5th natatory 

 legs is very short and the chela more spinous than that of L. kroyeri. In other 

 respects there is a close similarity between the species and this variety.
