on top of head, not on rostrum, without pigment (as preserved), but with numerous 

 highly refractive lenses. Postero-inferior angle of pleon segment 3 rounded. Telson 

 short, broader than long, apically emarginate, a spinule on each rounded postero-lateral 

 corner. 



Antenna 1 shorter than antenna 2, the latter elongate in <$ . Upper lip ovate, longer 

 than broad. Mandible, molar with well-developed triturating surface, palp linear, well 

 developed, 2nd joint not strongly curved. Lower lip with inner lobes separate. Maxilla 1, 

 inner lobe small, tipped with 1-2 setae. 



Gnathopod 1 stronger than gnathopod 2, 5th joint with broad round lobe, 6th joint 

 ovate, slightly longer than 5th, palm longer than hind margin. Gnathopod 2, 5th joint 

 with fairly broad lobe, but not so broad as in gnathopod 1, 6th joint ovate, but narrower 

 than in gnathopod 1 . 



Uropods with the rami subequal ; the 3rd uropod not extending beyond the other two.

Remarks. The structure of the eyes invites comparison with Oediceroides brevirostris ,

Although typically the process of 5th joint of gnathopod 2 extends nearly or quite to 

 the end of the hind margin of 6th joint, there are species (e.g. latimaniis) in which it is 

 shorter. All the species here described have a relatively short process.
