 almost completely separating the basal segment of the antennule from the 

 orbital hiatus. A complete separation found in [Thyrolambrus] and 

 Oethra. Carapace very rough, but little pitted. Rostrum very short and 

 bent off vertically. Legs spiny. (Flipse) 



Range: Eastern Pacific from Cape San Lucas, Lower California, 

 Mexico, to Octavia Bay, Colombia ; Galapagos Islands. Eastern Atlantic 

 at Cape Verde Islands. Indo-Pacific from Red Sea to Japan and east 

 to Hawaii.
