Type species. Gammaropsis atlantica Stebbing, 1888 . Etymology . From the Latin latus = broad (relating to the relatively broad uropod 3 peduncle) as a prefix to Gammaropsis , its close relative. Diagnosis. Gammaropsis sensu lato with head anterodistal margin strongly recessed; lateral cephalic lobes rounded; labrum lacking acute epistome; mandible palp article 3 spatulate, widest subdistally; coxae 1– 2 without serrations on distal margin; pleon segments lacking spines; uropod 3 peduncle short and broad, rami short and stout; outer ramus blunt-ended with a small second article bearing two fine setae, bordered on distal end of first segment by one or more robust setae; inner ramus subequal with or shorter than outer ramus, narrowing distally, with a single small robust seta inserted at its tip, lateral margins naked or with one or two robust setae.
