Parabrachiella jarai sp. nov. (Crustacea: Copepoda: Siphonostomatoida) parasitic on Sillago sihama (Actinopterygii: Perciformes: Sillaginidae)

Seasonality of Parasitic Copepods on Bullseye Puffer, Sphoeroides annulatus (Pisces: Tetraodontidae), From the Northwestern Coast of Mexico

“…Parabrachiella sp. probably represents an unknown species; however, its identification must be considered with caution because, according to Piasecki et al (2010), many of the existing species have been inadequately described and illustrated. In the present study, new geographical records and new host species records are given for P. diceraus and for C. serratus.…”

Redescription of Parabrachiella bera (Copepoda: Siphonostomatoida: Lernaeopodidae) Parasitic on Parajulis poecilepterus (Actinopterygii: Perciformes: Labridae) from Korea

“…In Korean waters, P. bera was found to be parasitic on P. poecilopterus, however P. incurva has to date not been recorded. Members of Parabrachiella are sufficiently host-specific and the geography of their hosts was reported by Piasecki et al (2010). All of these features clearly assure the identity of the redescribed specimens in relation to related species from the genus Parabrachiella.…”

“…Parabrachiella bera has four pairs of posterior processes in Japan (Yamaguti, 1939), but Korean specimens had a single pair of posterior processes. Parabrachiella bera has been assigned to Group II, which is the largest group, consisting of 35 members, in Parabrachiella (Piasecki et al, 2010). Careful comparison between the current materials and the original description of P. bera provided by Yamaguti (1939) revealed several omissions, in that the fine setulose ornamentation of the maxillule was not shown and the mandible was not described.…”

“…Lernaeopodid copepods currently include about 267 valid species (Boxshall and Halsey, 2004;Boxshall and Walter, 2012); they are most widely adjusted to parasitism (Kabata, 1986) and are highly host-specific (Piasecki et al, 2010). The genus Parabrachiella Wilson, 1915 was proposed to accommodate some species that were previously placed in the genus Neobrachiella Kabata, 1979(Piasecki et al, 2010, and currently consists of 67 valid species (Piasecki et al, 2010;Boxshall and Walter, 2012).…”

New records of parasitic copepods (Crustacea, Copepoda) from marine fishes in the Argentinean Sea

“…Recently, the species assigned to this genus by Kabata (1979) were transferred to Parabrachiella Wilson Halsey 2004, Piasecki et al 2010). Species of Parabrachiella seem to be highly host specific infecting a single fish species or a few closely related hosts (Piasecki et al 2010). The finding of P. amphipacifica in the psychrolutid C. granulosus represents a new host record and the first record of this species in Atlantic waters.…”
