Abstract
ABSTRACT Metacirolana nicosmiti sp. nov. is described from coral reefs at Viti Lifu, Fiji. The species is characterized by a unique ornamentation of prominent ridges on the head forming a ‘diamond’ shape, three longitudinal ridges on the pleotelson and a broad subtruncate pleotelson posterior margin (among other characters). A revised genus diagnosis is given to Metacirolana, together with discussion of the characters of the ‘Eurydicinae’, that is those cirolanid genera with a blade-like clypeus. We conclude that while the subfamilies of the Cirolanidae remain phylogenetically untested the characters that they present are relevant in assessing generic characters within the family and are useful in facilitating the identification of genera. http://zoobank.org:pub:9EAC6EF8-3882-480C-BE7B-48BFDB35B40A
