A new species of Orthopsyllus Brady & Robinson, 1873 (Copepoda: Harpacticoida: Orthopsyllidae) from Maxwell Bay, King George Island, Antarctica

Rhoicosphenia michali sp. nov., described from the shallow sublittoral zone in Antarctica, is the second species in the genus with just one raphe slit on its convex valve. The first species, Rhoicosphenia flexa, was also described from marine coastal habitats in the Southern Hemisphere. Here, the morphology and ecology of R. flexa and R. michali are compared. The new species described herein may be endemic to Antarctica and can be found as free living cells on the shallow seabed, although it mainly occurs on the red alga Georgiella confluens, which is endemic to Antarctica.

A New Species

Fragments of large, bilamellar aspidostomatid bryozoan colonies occur in Early Miocene glaciomarine sedimentary sequences of the Cape Melville Formation, King George Island, South Shetland Islands, West Antarctica. Investigation of the morphological characters of this aspidostomatid cheilostome shows that it represents a new species, which is described herein as Aspidostoma melvillensis sp. n. A combination of the colony-growth pattern, inferred co-occurring biota and associated sedimentary structures indicates a comparatively deep-water, outer shelf palaeoenvironmental setting. This Miocene occurrence of Aspidostoma melvillensis sp.n. emphasizes a biogeographical link with adjacent Southern Hemisphere regions during the early Neogene.
