Three species of digenetic trematodes of the Family Hemiuridae Looss, 1899, Subfamily Aphanurinae Skrjabin & Guschanskaja, 1954 with their prevalence, intensity of infection and mean abundance are reported Aphanuroides lethrini, Aphanurus stossichii and Aphanurus tuberculatus. A total of 26 specimens of Thryssa malabarica (Bloch, 1795) were examined for digenean infection. Prevalence of infection of A. lethrini, A. stossichii and A. tuberculatus were 11.53%, 69.23% and 15.38%, respectively, the intensity of infection were 1.6, 3.1 and 2.5 and the mean abundance were 0.19, 2.15 and 0.38, respectively. The prevalence, intensity and mean abundance of infection were at the maximum level in A. stossichii infection. Recovery of these parasites from T. malabarica represents a new host record and the first report from Kerala. The characteristic features of the recovered digeneans are discussed.

AbstractSix species of Bucephalidae are reported: Subfamily Bucephalinae: Bucephalus sphyraenae Yamaguti, 1952 from Sphyraena obtusata and S. chrysotaenia (Sphyraenidae) (new host records); Bucephalus margaritae Ozaki and Ishibashi, 1934 from Atropus atropos, Scomberoides commersonianus, Carangoides malabaricus (Carangidae), Gerres filamentosus (Gerreidae) (new host record) and Sphyraena jello (new host record); Rhipidocotyle pseudorhombi n. sp. from Pseudorhombus arsius is characterized by and differs from its congeners by several characteristics including an elongate body, a rhynchus with 7 thin papillae, a long tuular caecum extending posteriorly to the ovarian level, goads in the posterior half of the body, and contiguous testes not separated by uterine coils. More specifically it differs from R. heptathelata and R. septapapillata by having a long cirrus sac relative to body length, tandem and more anterior testes. Subfamily Prosorhynchinae: Prosorhynchus pacificus Manter, 1940 from Epinephelus tauvina (Serranidae) and Gnathonodon speciosus (Carangidae) (new host record); P. epinepheli Yamaguti, 1939 from Epinephelus areolatus; P. manteri Srivastava, 1938 from Trichiurus lepturus (Trichiuridae). All species, except Prosorhynchus epinepheli represent new records from the Arabian Gulf.

AbstractCystacanths of the acanthocephalan, Bolbosoma vasculosum Rudolphi 1819, were found to be encapsulated in the connective tissues of the viscera of the black scabbard fish, Aphanopus carbo and oceanic horse mackerel, Trachurus picturatusfrom Madeira, Atlantic Ocean. Juvenile worms were obtained from the intestine of a stranded common dolphin, Delphinus delphis, also from Madeira. Cystacanths were 11–15 mm long, with a proboscis of 18–19 longitudinal rows, eight hooks per row, and two sets of trunk spines. Overall, the morphology and dimensions of the proboscis, neck and trunk corresponded to previous descriptions. Scanning electron microscopy of the proboscis structures and trunk spines is provided for the first time. The prevalence of B. vasculosum in A. carbo increased with fish length. There were no statistical differences in the prevalence and intensity of infection between seasons. The intensity of infection was similar for male and female fishes, but there were significant differences in relation to length, longer fishes having heavier infections. Aphanopus carbo from Madeira represents a new host record and a new geographic location for B. vasculosum.

From Phoca vitulina richardi the following parasites are recorded: Corynosoma strumosum (Acanthocephala); Terranova decipiens and Contracaecum osculatum (Nematoda); Halarachne sp. (Acarina); Echinophthirius horridus (Anoplura). From Eumetopias jubata are recorded Diphyllobothrium pacificum, Diplogonoporus tetrapterus and Abothrium gadi (Cestoda); T. decipiens, C. osculatum and Parafilaroides sp. (Nematoda); Corynosoma villosum (Acanthocephala); Orthohalarachne diminuata (Acarina): Antarctophthirus microchir (Anoplura). E. jubata is probably not a true host of A. gadi, the parasite apparently being introduced by ingestion of infected fishes of the family Gadidae, the normal definitive hosts. Notes on host and geographical distribution, nomenclature and morphology of the parasites are included. Diphyllobothrium pacificum is a new combination for Adenocephalus pacificus. E. jubata is a new host record for D. pacificum, D. tetrapterus and O. diminuata. Several new geographical records are reported. The occurrence of larval stages of T. decipiens and C. strumosum in fishes is noted.

A novel ascomycetous genus, Elongaticollum, occurring on leaf litter of Hedychium coronarium (Zingiberaceae) in Taiwan, is described and illustrated. Elongaticollum is characterized by dark brown to black, superficial, obpyriform, pycnidial conidiomata with a distinct elongate neck, and oval to oblong, hyaline, aseptate conidia. Phylogenetic analyses (maximum likelihood, maximum parsimony and Bayesian) of combined ITS, LSU, SSU and tef1-α sequence data revealed Elongaticollum as a distinct genus within the family Phaeosphaeriaceae with high statistical support. In addition, Ophiosphaerella taiwanensis and Phaeosphaeriopsis beaucarneae are described as new species from dead leaves of Agave tequilana and Beaucarnea recurvata (Asparagaceae), respectively. Neosetophoma poaceicola is reported as a new host record from dead leaves of Musa acuminata (Musaceae). Newly described taxa are compared with other similar species and comprehensive descriptions and micrographs are provided.

An investigation of the digenetic trematodes of anurans from Agbede, a location in the derived savanna biotope in Edo state,Nigeria was conducted from August, 2007 to July, 2008. Anuran hosts examined included Sclerophrys maculata, S.regularis, Ptychadena pumilio, P. bibroni, P. oxyrhynchus, Hoplobatrachus occipitalis and Hylarana galamensis. Theanurans were collected using the Visual Acoustic Encounter Survey (VAES) method, dissected and examined for trematodeinfections. A total of 267 anurans were examined of which 33 were infected with an overall prevalence of 12.36%. Seasonalprevalence was 14.88% for the wet season and 8.08% for dry season. The difference in prevalence values was not statisticallysignificant (p >0.05). Four digenetic trematodes, namely, Mesocoelium monodi, an unidentified Mesocoelium sp.,Haematoloechus exoterorchis and an unidentified Haematoloechus sp. Haematoloechus exoterorchis was recovered from H.occipitalis while the unidentified Haematoloechus sp. infected H. occipitalis and Sclerophrys maculata. Mesocoeliummonodi infected only Sclerophrys maculata while the unidentified Mesocoelium sp. was a generalist, infecting five anuranhosts. Sclerophrys maculata is thus a new host record for the genus Haematoloechus in Nigeria. In conclusion, this studyrevealed a low trematode diversity in the anurans of the savanna-mosaic at Agbede. However, anurans from this locationharboured two new trematodes: an unidentified Mesocoelium sp and a Haematolechus sp. Sclerophrys maculata as a newhost record for the genus Haematoloechus in Nigeria. More specimens of the Haematoloechus sp. are needed for themorphological description and molecular characterization of the parasite, to establish its relationship with the cogener inH.occipitalis.

AbstractTwo nematode species of the family Cystidicolidae were collected from the digestive tract of marine fishes off New Caledonia, South Pacific: Ascarophis adioryx Machida, 1981 from the stomach of the speckled squirrelfish Sargocentron spiniferum and the sabre squirrelfish Neoniphon sammara (new host record) (both Holocentridae, Beryciformes), and a Spinitectus sp. female, morphologically similar to S. beaveri Overstreet, 1970, from the roundjaw bonefish Albula glossodonta (Albulidae, Albuliformes). Based on light and scanning electron microscopy examinations, A. adioryx is redescribed and a new subgenus Dentiascarophis subgen. nov., characterized by the presence of one dorsal and one ventral median protrusions in the mouth, is established to accommodate it; a key to subgenera of Ascarophis is provided. Ascarophis holocentri Parukhin, 1984 is considered a junior synonym of A. adioryx. The cephalic structure of Spinitectus sp. and S. beaveri is very different from those in other congeners and, therefore, a new subgenus Paraspinitectus subgen. nov., characterized by highly reduced pseudolabia, is erected to accommodate these species. The hemiurid digenean Lecithochirium cirrhiti (Manter et Pritchard, 1960) Yamaguti,1970 was found in the stomach of three species of squirrelfishes. Findings of A. (D.) adioryx, Spinitectus (P.) sp. and L. cirrhiti in New Caledonian waters represent new geographical records of these parasites.

A large collection of mesoparasitic copepods from polychaete hosts collected in northern European waters was examined. The term mesoparasitic refers to highly transformed copepods where the adult female attaches by embedding part of its body in the host. Representatives of five known familes were found and a new family is established. A single new species, Bradophila minuta sp. nov., was described in the family Bradophilidae. It occurred exclusively on the flabelligerid Diplocirus glaucus (Malmgren, 1867). Two genera of the family Herpyllobiidae were represented: Herpyllobius Steenstrup & Lütken, 1861 and Eurysilenium M. Sars, 1870. Herpyllobius arcticus Steenstrup & Lütken, 1861 was found on at least five different polynoid hosts, two of which, Harmothoe fragilis Moore, 1910 and Antinoe sp., were new host records. A new species, H. cluthensis sp. nov. was described from Malmgrenia species in Scottish waters. The large species, Herpyllobius cordiformis Lützen, 1964, was collected in Arctic waters from Eunoe cf. oerstedi. It is the first report of this parasite in Europe. The common parasite H. polynoes (Krøyer, 1864) was found on six different polynoid hosts, three of which, Harmothoe bifera, Malmgreniella mcintoshi Tebble & Chambers, 1982 and Eunoe ?barbata are new host records. Eurysilenium truncatum M. Sars, 1870 was collected from Eucranta villosa Malmgren, 1866, Eunone sp., and Gattyana cirrhosa (Pallas, 1766). The material from Eucranta villosa caught at 72.6ºN comprises both a new host record and is the most northerly report of this parasite. Specimens of Eurysilenium which differed from E. truncatum in a number of features were found on Harmothoe fragilis and H. impar (Johnston, 1839). A new family, the Pholoicolidae, is established to accommodate Pholicola chambersae gen. et sp. nov., parasitic on Pholoe pallida Chambers, 1985. The family Phyllodicolidae was represented by all three of its known species: Phyllodicola petiti (Delamare Deboutteville & Laubier, 1960), Cyclorhiza eteonicola Heegaard, 1942 and C. megalova Gotto & Leahy, 1988. The former was found on Eumida ockelmanni Eibye-Jacobsen, 1987, a new host record. A single ovigerous female of C. eteonicola was collected from a new host, Eteone spetsbergensis Malmgren, 1865. Cyclorhiza megalova was common on Eteone longa (Fabricius, 1780) and E. longa/flava complex. A rich diversity of members of the family Saccopsidae was found, including three known species of Melinnacheres M. Sars, 1870 plus nine new species placed in four new genera. Melinnacheres was represented by M. ergasiloides M. Sars, 1870, M. steenstrupi Bresciani & Lützen, 1961 and M. terebellidis Levinsen, 1878. Melinnacheres ergasiloides was found on Melinna elizabethae McIntosh, 1914, M. steenstrupi on members of the Terebellides stroemi-complex and T. atlantis Williams, 1984, while M. terebellidis was found on the T. stroemi-complex and on T. shetlandica Parapar, Moreira & O'Reilly, 2016. A new genus, Trichobranchicola gen. nov., was established to accommodate T. antennatus gen. et sp. nov., a parasite of Trichobranchus sikorskii Leontovich & Jirkov in Jirkov, 2001, T. glacialis Malmgren, 1866 and Trichobranchus sp. The second new genus, Lanassicola gen. nov., was established to accommodate the type species, Lanassicola arcticus gen. et sp. nov. parasitic on Lanassa venusta (Malm, 1874), plus two additional species, L. bilobatus gen. et sp. nov. on Lanassa nordenskjoeldi Malmgren, 1866, and L. dorsilobatus gen. et sp. nov. on Proclea graffii (Langerhans, 1884). A new subfamily, Euchonicolinae, was established within the Saccopsidae to accommodate two new genera, Euchonicola gen. nov. and Euchonicoloides gen. nov. The type species of Euchonicola gen. nov. is E. caudatus gen. et sp. nov., a parasite of Euchone sp., and it includes two other species, E. linearis gen. et sp. nov. on Chone sp., and E. parvus gen. et sp. nov. on Euchone sp. The type species of Euchonicoloides gen. nov. is E. elongatus gen. et sp. nov. found on a host belonging to the genus Euchone, and it also includes Euchonicoloides halli gen. et sp. nov. from Jasmineira caudata Langerhans, 1880. Four species of the family Xenocoelomidae were found: Xenocoeloma alleni (Brumpt, 1897), X. brumpti Caullery & Mesnil, 1915, X. orbicularis sp. nov. and Aphanodomus terebellae (Levinsen, 1878). Xenocoeloma alleni was found on four different species of Polycirrus and on Amaeana trilobata (M. Sars, 1863) and X. brumpti was found on Polycirrus norvegicus Wollebaek, 1912. Xenocoeloma orbicularis sp. nov. occurred only on Paramphitrite birulai (Ssolowiew, 1899). Aphanodomus terebellae was found on three hosts, only one of which, Leaena abranchiata was new.

AbstractThe biota associated with Monochamus species collected in Maine include species of Acarina, Diptera, Hymenoptera and Nematoda, as well as fungal and bacterial pathogens.Mites belonging to seven families and thirteen genera were found in association with the sawyers. Two species were previously unknown and have since been described as the new genus and species Longoseius cuniculus Chant of the family Digamasellidae and the new genus and species Mucroseius monochami Lindquist of the family Blattisocidae. Parasitic diptera belonged to three genera in three different families, and of these one contained a new species, Forcipomyia innom., family Ceratopogonidae, which was found as an intermittent parasite of adult Monochamus notatus and Monochamus scutellatus. This constitutes a new host record for the biting midge family. Only one hymenopterous parasite, a species of Dolichomitus was reared from a sawyer larva. The five genera of nematodes isolated from larvae, pupae, and adults of Monochamus species include specimens of the genus Hexamermis. Parasitism by this group is thought to be unusual because of the relative inaccessibility of the host. Isolates from eight fungal genera were obtained, and strains of Beauveria bassiana, and Isaria farinosa, were shown to be pathogenic. The bacteria isolated from dead sawyers included Aerobacter aerogenes, Bacillus cereus var. mycoides, and one unidentified species. Only the tachinid E. monohammi and the mite Uropoda have been previously reported of the large number of organisms found associated with sawyer beetles in this study. The fungus Beauveria bassiana proved to be the most important biological control agent.
