A new genus and a new species of Clausiidae (Crustacea, Copepoda) parasitic on Dipolydora armata (Polychaeta, Spionidae) in Brazil

Abstract

A new genus and species of parasitic copepod (Clausiidae), Spionicola mystaceus, associated with the polychaete Dipolydora armata (Spionidae) is described and figured. The new copepod has an elongate body, 5-segmented antennule, 2-segmented rami on legs 1 and 2, 2 spines representing leg 3, no leg 4, leg 5 well developed and reduced armature elements on feeding limbs. The host is a mollusk-shell borer, collected off São Sebastião Island, State of São Paulo, Brazil.

Polychaete-parasitizing copepods from the deep-sea Kuril–Kamchatka Trench (Pacific Ocean), with the description of a new Ophelicola species and comments on the currently known annelidicolous copepods

“…However, these genera have also very reduced and modified legs 1-4, present the typical clausiid maxillule and maxilla, and have a single free abdominal segment. The clausiid genus Spionicola Bjornberg & Radashevsky, 2009 shares the 5-segmented antennules with Ophelicola (Björnberg and Radashevsky, 2009), but clearly differs in all remaining characteristics. Ophelicola resembles the clausiid genus Rhodinicola Levinsen, 1878 in having 3-segmented rami of legs 1-4 and in lacking posterior median element at the basis of leg 1 (Björnberg and Radashevsky, 2011).…”

The First Record of a Species of Clausiidae (Copepoda: Cyclopoida) from Japanese Waters, with the Proposal of a New Genus

“…Boxshall and Halsey (2004) also reviewed and re-diagnosed the Clausiidae, excluding Synaptiphilus, Presynaptiphilus, Stockia, and Teredicola from the family. Since that revision of the family concept, Spionicola, Boreoclausia, Sheaderia, and Vivgottoia have been added (Björnberg and Radashevsky 2009;Kim et al 2013). Thus, 12 genera are currently accepted as members of the family.…”

A new species of Rhodinicola (Copepoda: Clausiidae), parasitic copepod of the shell-boring polychaete Polydora brevipalpa (Annelida: Spionidae) from the Sea of Japan

“…Based on these results, the authors established a new genus Likroclausia Ho et Kim, 2003and suggested that the Clausia Claparède, 1863, Mesnilia Canu, 1898, Pontoclausia Bãcescu et Por, 1959, Pseudoclausia Bocquet et Stock, 1960, and Rhodinicola Levinsen, 1878 should be treated as valid genera in the Clausiidae, while the taxonomical status of the genera Indoclausia Sebastian & Pillai, 1974, Megaclausia OReilly, 1995, Pherma Wilson C.B., 1923, and Seridium Giesbrecht, 1895 remains uncertain. Since then, a new genus Spionicola was established by Björnberg and Radashevsky (2009) to accommodate a new species from Brazil, S. mystaceus Björnberg et Radashevsky, 2009. In the Asian Pacific, nine species of copepods from the families Clausidiidae, Clausiidae and Sabelliphilidae have been described as ectoparasitic on the adult polychaetes from the families Arenicolidae, Capitellidae, Nereididae, Sabellidae and Terebellidae from the coastal waters of the Korea Straight and the Yellow Sea in Korea , 2003Kim, Ho, 1992;Kim, 1998Kim, , 2000Kim, , 2001a. Unidentified copepods endoparasitic in the adults of Polydorella Augener, 1914 (Spionidae) were reported from the South China Sea, Vietnam (Radashevsky, 1996) and Philippines (Williams, 2004).…”
