Pseudorostral lobes meetiug in front of the eyelobe. Carapace narrow, 

 without hiteral cornua. First pedigerous segment short but distinct. Only 

 the first pair of peraeopods carrying exopods in either sex; second peraeopods 

 with the third joint obsolete. Endopod of uropods two- jointed, the second 

 joint usually the longer.

 the produced lateral corners of which carry convergent tufts of setae; antero- 

 lateral corners acute in 9 . not produced in d . Carapace with median keel 

 and 2 weak pairs of lateral keels anteriorly. Pedigerous segments 3 and 4 

 of d as in /. zimmeri (nr. 2) and /. hrevipe.s (nr. 3). Telsonic segment roundly 

 produced between the uropods at their base and showing a dorsal depression.
