Towards a revised Amphinomidae (Annelida, Amphinomida): description and affinities of a new genus and species from the Nile Deep-sea Fan, Mediterranean Sea

摘要: Borda, E., Kudenov, J.D., Bienhold, C. & Rouse, G.W. (2012). Towards a revised Amphinomidae (Annelida, Amphinomida): description and affinities of new genus species from the Nile Deep-sea Fan, Mediterranean Sea. —Zoologica Scripta, 41, 307–325. The discovery amphinomid wood falls deployed near cold seeps (1694 m) at Fan (Mediterranean Sea) highlights need to revise better characterize diversity. The phylogenetic 12 other nine Amphinomida genera were inferred using data two nuclear (18S rDNA 28S rDNA) mitochondrial (COI 16S genes. analyses indicated close relationship with amphinomids associated temporary pelagic substrata, including Amphinome sensu stricto (emended herein) Hipponoa. belongs distinct lineage we, here, erect accommodate it. Cryptonome gen. n. is second established for chemosynthetic environments. conclava sp. distinguished morphologically all previously described rectilinear by lacking notochaetal hooks, having reduced caruncle, modified neurochaetae branchiae on nearly segments. Taxonomic issues regarding presently assigned erroneous placement related xylophylic taxa in Eurythoe are also outlined. We emend restrict five known oceanic flotsam stalked heart-shaped caruncles stricto. An additional 15 may belong (e.g. Linopherus) here tentatively considered incertae sedis. Finally, turcica parvecarunculata transferred as combinations. A key subset (relevant this study) presented.
