Cheus annae, new genus, new species (Cheidae, new family), a fossorial amphipod from the Falkland Islands
Cheus annae, new genus, new species, is described and figured. Comparisons with the Phoxocephalidae, Urothoidae, Platyischnopidae, Haustoriidae, and Pontoporeiidae show many characters in common, particularly with the first three families. The combination of a hoodlike rostrum with a presumed glandular apex, and low morphological diversification of peraeopods 5-7 requires the erection of a new family, the Cheidae.
