“…Members of this genus have been recorded as symbionts of a wide range of marine invertebrates, mainly different groups of Echinodermata, but also, less frequently, Platyhelminthes, Nemertea, Bivalvia and a few polychaetes (Illg, 1950;Stock, 1995a;Humes & Boxshall, 1996). Members of the family Clausiidae Giesbrecht, 1895 are the commonest symbionts on polychaetes (Ho & Kim, 2003) and, outside this taxon, the associations between copepods and polychaetes are rare (Boxshall & Halsey, 2004). Furthermore, Gotto (2004) considered that for some records of Pseudanthessius on polychaetes these worms might be ''accidental hosts''.…”

The copepod order Cyclopoida contains mainly forms that have been found as symbionts of different vertebrate and invertebrate hosts. One of these groups is the family Pseudanthessiidae, found mainly on echinoderms but very rarely on polychaetes. In this contribution, we report and confirm the occurrence of the pseudanthessiid copepod Pseudanthessius tortuosus Stock, 1967 as a symbiont of the benthic amphinomid polychaete Hermodice carunculata (Pallas) in the western Caribbean. These specimens showed subtle morphological but important size differences with respect to the specimens from the type-locality in the eastern Caribbean. Data are provided on the sex-ratio, the distribution of the copepods on the polychaete body and the finding of pairs in amplexus. The position of the copepods on the body, mainly on the dorsal branchiae, rather than on the lateral ones, allows them to avoid the friction related to the displacement mechanism of the polychaete, involving the lateral branchiae. This is the first record of the species and the symbiotic association in the western Caribbean and in Mexican waters. It is also recorded herein for the first time in the US Virgin Islands, near the type-locality. Hitherto, P. tortuosus has not been recorded since its original description forty years ago. This finding supports the hypothesis that this copepod is associated to H. carunculata throughout the entire Caribbean Basin, but its relation with other amphinomids remains unconfirmed.

“…Except for Hyphalion Humes, 1987, Conchyliurus, andHermadona Ho &Kim, 2004, most female clausidiids have well-developed 4-segmented maxillipeds (Ho and Kim, 2003), contrarily to the rudimentary limbs of Ophelicola females. Furthermore, the antennules of the Clausidiidae, with the exception of Hermadona, Conchylirius, and Hersilioides Canu 1888, are 7segmented (Boxshall and Humes, 1987;Ho and Kim, 1990, 2003. Moreover, the derived structure of the mandible excludes Ophelicola from the Clausidiidae and indicates a possible relationship with the Clausiidae (Boxshall and Halsey, 2004).…”

The annelid associated copepods, collectively called annelidicolous, were placed in 21 families. Some genera, such as Ophelicola, are considered phylogenetically isolated and are placed into the order Cyclopoida as incertae sedis. In this paper, we describe Ophelicola kurambia, the second species recorded for the genus and the first for the Pacific Ocean. The single known specimen, a female, was found during the German-Russian deep-sea expedition KuramBio at the deep-sea Kuril-Kamchatka Trench. The new species differs from Ophelicola drachi (known from the Gulf of Biscay, Atlantic Ocean) in being attached to the host through the mandibles instead of maxillae and, specially, in the formula of the antennular armature. The study of the new species contributes to clarify the diagnosis of the genus, which clearly differs from Notomasticola (another incertae sedis genus), and resembles both the most modified clausiids (in the mandibular shape and antennular segmentation) and the clausidiids (in the shape of maxilla). However, it does not contribute to clarify the position of Ophelicola within the order Cyclopoida. The paper includes a list of the known annelidicolous copepods (excluding Monstrilloidae) and summarizes the main trends shown in terms of diversity, distribution and relationships. Currently, 168 species of copepods from to 74 genera and 22 families and 7 incertae sedis (excluding Monstrilloida) are known to be involved in 235 parasitic relationships (mostly ectoparasitic) with polychaetes. Host polychaetes include 156 species belonging to 104 genera from 22 families (plus 14 unknown). About 50% of these relationships are known from European waters, mainly from shallow depths.
