Latigammaropsis gen. nov.

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.

Barnard, 1965) , L. afra ( Stebbing, 1888) , L. athenae sp. nov., L. atlantica ( Stebbing, 1888) , L. christenseni ( Myers, 1995) , L. dionysus sp. nov., L. gemina ( Myers, 1995) , L. grandimana ( Ledoyer, 1978) , L. hermes sp. nov., L. hestia sp. nov., L. kaumaka (J.L.
