Abstract
Background In total, 14 species of Caligus have been reported from Malaysia. Amongst them, four species are reported from lutjanid fishes. New information Caligusdussumieri Rangnekar, 1957 is reported from Malabar snapper, Lutjanusmalabaricus, purchased from a local wet market in Terengganu, Peninsular Malaysia. This is the first record of this species in Malaysia and it is only the second species assigned to the bonito-group of the genus Caligus to be reported from Malaysia. A key to species of the bonito-group is presented herein. The list of caligids infecting lutjanid fishes and the geographical distributions plus the known hosts of members of the bonito-group of Caligus are discussed.

Tavares-Dias M, Oliveira MSB. Global distribution patterns of Caligus Müller, 1785 (Copepoda: Caligidae) associated to teleost fishes, with physiological and histopathological data and description of treatment strategies. AN ACAD BRAS CIENC 2023; 95:e20220281.

Abstract
This review surveyed information on Caligus Müller, 1785 to identify global infestation patterns and geographic distribution in teleost fishes, as well as physiological and histopathological data and description of treatment strategies. A total 990 samples of Caligus spp. (N = 212 species) obtained of 233 scientific papers on farmed and wild teleost species from 99 families and 30 orders were used, and the highest number of occurrences was on Carangidae. Caligus spp. was predominantly found in marine environments, and only Caligus lacustris and Caligus epidemicus were found in teleost fish of freshwater environments. There was a high prevalence of Caligus spp. on hosts and infestation occurred predominantly in both the tegument and the gills. Caligus species are distributed across different countries and some particularities were identified and discussed. Caligus elongatus and Caligus bonito bonito had the broadest geographic distribution. Histomorphological and hematological disorders caused by infestation by Caligus spp. were reported and discussed, as well as chemotherapeutic products used for controlling and treating the infestations. Variation in the distribution and geographic patterns of Caligus spp. were little evident in many ecosystems and due to the limited data on the infestation of these sea lice on teleost populations in different regions.

Abstract
Thirteen species of sea lice (family Caligidae) are reported from a range of elasmobranch and actinopterygian fishes caught off South Africa or obtained from public aquaria in South Africa. Two new species of Caligus Müller, 1785 are described: C. linearis n. sp. from Pomatomus saltatrix (Linnaeus) and C. tumulus n. sp. from Chrysoblephus cristiceps (Valenciennes). A supplementary description is provided for both sexes of Caligus tetrodontis Barnard, 1948 taken from Amblyrhynchotes honckenii (Bloch) and previous records of this parasite from South African fishes are critically reviewed. It is concluded that Caligus material from Arothron hispidus Linnaeus was previously misidentified as C. tetrodontis and is in urgent need of re-examination. Morphological and molecular observations on Caligus furcisetifer Redkar, Rangnekar & Murti, 1949 indicate that this copepod is phenotypically and genetically identical to Lepeophtheirus natalensis Kensley & Grindley, 1973, and the latter becomes a junior subjective synonym of C. furcisetifer. We include new geographical distribution records for Caligus longipedis Bassett-Smith, 1898, C. rufimaculatus Wilson, 1905 and Lepeophtheirus spinifer Kirtisinghe, 1937, extending into South African waters, as well as both new distribution and host records for Alebion gracilis Wilson, 1905, Caligus dakari van Beneden, 1892 and Lepeophtheirus acutus Heegaard, 1943. The molecular analysis confirmed the monophyly of the genus Caligus. The South African species of Caligus did not cluster together, but the two included South African species of Lepeophtheirus were recovered as sister taxa.

Caligus madeirensis sp. nov. (Copepoda: Caligidae) Parasitic on Pompano, Trachinotus ovatus (Linnaeus, 1758), from Eastern Atlantic Waters, Surrounding the Madeira Archipelago, Portugal. Acta Parasitol 2021; 66:361-376. [PMID: 32997241 PMCID: PMC7526516 DOI: 10.1007/s11686-020-00290-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2020] [Accepted: 09/22/2020] [Indexed: 10/28/2022]
Abstract
INTRODUCTION A new species of the genus Caligus is described based on specimens collected from pompano, Trachinotus ovatus (Linnaeus), caught in eastern Atlantic waters, near the Madeira archipelago. METHODS Pompano (n = 21) were purchased from the local fish market and examined for parasitic copepods. Morphological features of the copepods were examined and drawn using an Olympus BX51 equipped with a drawing tube. Key diagnostic characters were scanned using a confocal laser scanning microscope and a scanning electron microscope. RESULTS Caligus madeirensis sp. nov., can be distinguished from all congeners (270 spp.) by the combination of the following characters: (i) an accessory process on the 3 outer terminal spines located on the distal exopodal segment of leg 1, (ii) a mandible with 14 teeth, (iii) a sternal furca with parallel, spatulate tines, (iv) a maxilliped with 2 simple setae at base of a claw, (v) a leg 3 with second endopodal segment with 5 pinnate setae, (vi) a 2-segmented leg 4 exopod with I; III spine formula, (vii) a male antenna with 4 overlapping plates on the distal segment, (viii) a male maxilliped corpus bearing a prominent myxal process ornamented with dense corrugations along inner margin. CONCLUSION Together with Caligus madeirensis sp. nov., the Caligus fauna of Portugal consists of 13 species reported from 17 Portuguese marine fishes. Considering the large number of marine fish species (510 spp.) currently recorded from Portuguese waters it seems that only 3.3% of the Portuguese marine fishes have been found to be infested with species of the genus Caligus O.F. Müller, 1758, the result of which, however, might be due to limited sampling.

Caligus tunisiensis n. sp. (Copepoda: Caligidae) parasitic on the painted comber Serranus scriba (L.) (Perciformes: Serranidae) from the Mediterranean Sea, off the Tunisian coast. Syst Parasitol 2020; 98:57-71. [PMID: 33211288 DOI: 10.1007/s11230-020-09959-9] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2020] [Accepted: 09/25/2020] [Indexed: 10/22/2022]
Abstract
A new species of parasitic copepod, Caligus tunisiensis n. sp. (Caligidae), is described based on two female specimens collected from the gills of the painted comber, Serranus scriba (L.), caught in the Mediterranean Sea, off the Tunisian coasts. The new species belongs to the Caligus productus-species group established by Boxshall & Gurney (1980) as it shares the following set of character states: (i) antenna with well-developed posterior process on proximal segment; (ii) posterior margin of distal exopodal segment of leg 1 lacking typical plumose setae, or retaining single vestigial seta; and (iii) 2-segmented exopod of leg 4 armed with IV spines on compound distal exopodal segment. Detailed morphological comparisons between the new species and the core members of the C. productus-species group revealed that the new species closely resembles with C. productus Dana, 1852 and C. temnodontis Brian, 1924. However, the new species can be distinguished from its congeners in having: (i) a female maxilliped bearing a prominent bi-lobate myxal process, opposing tip of the claw; (ii) leg 4 protopod ornamented with a patch of spinules on the posterolateral surface; and (iii) an abdomen ornamented with two rows of minute spinules at the posterolateral corners.

Sea lice (Copepoda: Caligidae) of Turkey, with the discovery of Caligus quadratus Shiino, 1954 in the Mediterranean Sea and the re-description of a rare caligid copepod, Caligus scribae Essafi, Cabral & Raibaut, 1984. Syst Parasitol 2020; 97:779-808.

Abstract
The current status of the caligid copepods parasitic on marine fishes off Turkey is reviewed and an updated checklist comprising a total of 24 species, belonging to three different genera, Caligus O. F. Müller, 1785, Euryphorus H. Milne Edwards, 1840 and Lepeophtheirus von Nordmann, 1832, is presented together with habitus illustrations and a key to all 24 species. Two of the species of caligids listed herein constitute new records for Turkish waters. The first, Caligus quadratus Shiino, 1954, a well-known species of the genus, was collected from the common dolphin fish, Coryphaena hippurus Linnaeus. The second, Caligus scribae Essafi, Cabral & Raibaut, 1984, a very rare and poorly known member of the genus, was sampled from a new teleost host, the parrot fish, Sparisoma cretense (Linnaeus). Both fish species were caught in north-eastern Mediterranean waters off the Turkish coast. Caligus quadratus is only briefly described based on key diagnostic characters whereas a full re-description is provided for C. scribae, as the only description available for this species is incomplete and lacks detail. Sparisoma cretense is a new host record for C. scribae. In addition, this is the first report of C. quadratus from the Mediterranean.

Abstract
In this study, supplementary information on the morphology of the siphonostomatoid copepod Caligus quadratus Shiino, 1954 (Copepoda: Caligidae) is given based on the new material collected from the gills of the Atlantic bluefin tuna, Thunnus thynnus (Linnaeus, 1758) caught in the Gulf of Antalya, Turkey. The morphology of C. quadratus is re-examined for the first time by adopting a recently developed visualisation technique by Kamanli et al. [1]. Appendages of Congo red stained specimens of C. quadratus were dissected and scanned using confocal laser scanning microscope (CLSM) and the CLSM images were processed using Dristhi software programme. 3D reconstructions of some confusing appendages were visualised using Drishti. Line drawing was used to depict the habitus of both female and male C. quadratus. Key diagnostic characters of C. quadratus are presented together with the newly observed additional taxonomic characters. In addition, previously misinterpreted and simply overlooked features in the previous descriptions of C. quadratus are also re-described. This is the first report of C. quadratus from the Mediterranean Sea and the Atlantic bluefin tuna constitutes a new host record for this caligid copepod.

Discovery of the fish host of the 'planktonic' caligid Caligus undulatus Shen & Li, 1959 (Crustacea: Copepoda: Siphonostomatoida). Biodivers Data J 2020; 8:e52271.

Abstract
The siphonostomatoid copepod Caligusundulatus Shen & Li, 1959 has been widely reported from plankton samples obtained from neritic and oceanic waters off coasts of the Indo-West Pacific and Atlantic Oceans. Until now, its fish host has remained unknown. This copepod belongs to an intriguing group of congeners that, despite being part of a chiefly parasitic group, are consistently found as zooplankters. Quite unexpectedly, in October 2019, a fish host of C.undulatus was discovered in the Seto Inland Sea, Japan—namely, the Japanese sardinella Sardinellazunasi (Bleeker, 1854). Both juvenile (chalimus) and adult individuals of this caligid were observed as parasites of the fish host. The discovery suggests that the species has an alternative life cycle as previously proposed for other purportedly ‘planktonic’ congeners and might frequently switch hosts during the adult stage. Thus, the C.undulatus group is newly proposed as a species group in the genus, in which five species are known as planktonic. Some hypotheses on the modified life cycle of caligids also briefly discussed.
