A New Species of <i>Kinorhynchus</i> (Homalorhagida, Pycnophyidae) from Australia with a Redescription and Range Extension of Other Kinorhyncha from the South Pacific

Abstract

Kinorhynchus phyllotropis sp.n., from Sydney Harbour, is the first species of the phylum Kinorhyncha to be described from Australian coasts. It appears to be most closely related to K. anomalus (Lang, 1953) from the Chilean coast and possibly, but to a lesser extent, to K. spinosus (Lang, 1949) from the Falkland Islands in the South Atlantic. Kinorhynchus anomalus is rede‐scribed and, along with the new species, is compared with the South Atlantic species, the two species known from the Northeast Pacific and the remaining four members of this genus from the North Atlantic, Mediterranean Sea and Black Sea. Cateria styx Gerlach, 1956, is reported from beaches north of Valparaiso, Chile, the first report of this mesopsarnmic cryptorhagid kinorhynch from the Pacific Ocean.
