Cichlidogyrus Paperna, 1960 (Monogenea, Ancyrocephalidae): gill parasites from West African Cichlidae of the subgenus Coptodon Regan, 1920 (Pisces), with descriptions of six new species

A study of gill parasites from fishes of the subgenus Coptodon Regan, 1920 (Cichlidae), namely Tilapia coffea Thys van den Audenaerde, T. dageti Thys van den Audenaerde, T. guineensis (Bleeker), T. louka Thys van den Audenaerde, T. walteri Thys van den Audenaerde and T. zillii (Gervais), from different locations in West Africa (Burkina Fasso, Congo, Ivory Coast, Guinea, Mali and Senegal), revealed the presence of 19 species of Cichlidogyrus Paperna, 1960 (Monogenea, Ancyrocephalidae). Six are considered new species: C. amphoratus n. sp., C. levequei n. sp., C. microscutus n. sp., C. ornatus n. sp., C. ouedraogoi n. sp. and C. yanni n. sp. The host-specificity of these parasites is discussed.     

Four new species of Cichlidogyrus Paperna, 1960 (Monogenea,Ancyrocephalidae), all gill parasites from African mouthbreeder tilapias of the genera Sarotherodon and Oreochromis (Pisces,Cichlidae), with a redescription of C. thurstonae Ergens, 1981

A study of Oreochromis niloticus (Linnaeus), O. aureus (Steindachner), Sarotherodon caudomarginatus (Boulenger), S. galilaeus (Linnaeus) and S. galilaeus sanagaensis (Thys van den Audenaerde) (Teleostei, Cichlidae) from different locations in Africa (Burkina Faso, Cameroon, Guinea, Niger and Senegal) revealed the presence of 11 species of monogenean gill parasites. Four, belonging to Cichlidogyrus Paperna, 1960 and considered as new species, are described: C. rognoni n. sp., C. douellouae n. sp., C. giostrai n. sp. and C. njinei n. sp. They are distinguished by the shape and/or size of the sclerotised parts of the haptoral and copulatory complexes. C. thurstonae Ergens, 1981 from O. niloticus is redescribed.     

Two new species of Cichlidogyrus Paperna, 1960 (Monogenea, ancyrocephalidae) gill parasites on Hemichromis fasciatus (Pisces, Cichlidae) in Africa, with remarks on parasite geographical distribution

The examination of gill parasites from Hemichromis fasciatus Peters, 1858 (Pisces, Cichlidae) in Africa revealed the presence of nine species of Monogenea, three belong to Onchobdella Paperna, 1968 and the others to Cichlidogyrus Paperna, 1960. Seven have been previously described (O. aframae Paperna, 1968; O. bopeleti Bilong Bilong & Euzet, 1995; O. voltensis Paperna, 1968; C. dageti Dossou & Birgi, 1984; C. euzeti Dossou & Birgi, 1984; C. falcifer Dossou & Birgi, 1984 and C. longicirrus Paperna, 1965); two, belonging to the latter genus, are considered as new species: C. sanseoi n. sp. and C. teugelsi n. sp. As parasitic species are not present in all the host distribution area, we think that H. fasciatus is made up of two distinct populations (or even sister species).     

New species of Cichlidogyrus Paperna, 1960 (Monogenea,Ancyrocephalidae) from the gills of Sarotherodon occidentalis (Daget) (Osteichthyes,Cichlidae) in Guinea and Sierra Leone (West Africa)

The examination of gill parasites from èSarotherodon occidentalisè (Daget) (Pisces, Cichlidae) in Guinea and Sierra Leone (West Africa) revealed the presence of seven species of Monogenea. Two of them have previously been described: ichlidogyrus halli; (Price & Kirk, 1967) and Scutogyrus ecoutini Pariselle & Euzet, 1995. Five are considered as new species, all belonging to Cichlidogyrus Paperna, 1960. They are C. bouvii n. sp., C. fontanai n. sp., C. guirali n. sp., C. paganoi n. sp. and C. sanjeani n. sp.Résumé L'examen des parasites branchiaux de Sarotherodon occidentalis (Daget) (Pisces, Cichlidae) en Guinée et en Sierra Leone (Afrique de l'Ouest) a révélé la présence de sept espèces de Monogènes. Deux ont déjàè été décrites: Cichlidogyrus halli (Price & Kirk, 1967) et Scutogyrus ecoutini Pariselle & Euzet, 1995. Cinq, appartenant toutes au genre Cichlidogyrus Paperna, 1960, sont considérées comme nouvelles, C. bouvii n. sp., C. fontanai n. sp., C. guirali n. sp., C. paganoi n. sp. et C. sanjeani n. sp.     

Monogenean stomach parasites of cichlid fishes from Cameroon: Two new species of the genusEnterogyrus Paperna, 1963 (Ancyrocephalidae)

Two ancyrocephalid monogeneans collected in Cameroon are described:Enterogyrus crassus n. sp. from the stomach ofTilapia nyongana andE. amieti n. sp. from the stomach ofSarotherodon galilaeus sanagaensis. The simultaneous occurrence ofE. cichlidarum Paperna, 1963 in the stomach of these two host species is also reported. The specificity of the two new species is discussed along with the value of haptor morphology (cupped or tongue-shaped) as a specific character in the taxonomy of the genusEnterogyrus.     

A new genus and three new species of dactylogyrids (Monogenea), gill parasites of the threadfin bass,Pronotogrammus multifasciatus Gill (Perciformes: Serranidae) in the Southeastern Pacific Ocean off Peru

Pronotogrammella n. g. is erected to accommodate Pronotogrammella boegeri n. sp. (type-species), Pr. scholzi n. sp. and Pr. multifasciatus n. sp. (Monogenea: Dactylogyridae). The new species are gill parasites of the threadfin bass Pronotogrammus multifasciatus Gill (Perciformes: Serranidae), a demersal teleost collected from off the coastal zone of Puerto Pizarro, Tumbes, Peru. Pronotogrammella n. g. is mainly characterised by having broadly fork-shaped dorsal anchors, which have an accessory anchor sclerite articulated to the tip of the superficial roots. Pronotogrammella n. g. is also characterised by having: (i) a tubular tapered-shaped male copulatory organ (MCO), filamentous distally, with a clockwise coil at distal end or not, lacking accessory piece; (ii) a dorsal bar with an anteromedial delicate umbelliform membrane supported by two processes; (iii) hooks with upright blunt thumb and uniform shank; (iv) a vaginal aperture dextrolateral; (v) a subquadrangular haptor, with inconspicuous lateral flaps and lacking haptoral reservoirs; and (vi) eye-spot or chromatic granules absent. Pronotogrammella boegeri n. sp. is characterised by its crosier-shaped MCO having a clockwise coil at distal end and by its dorsal bar with a straight anteromedial processes. Pronotogrammella scholzi n. sp. is typified by possessing of a dorsal bar with the anteromedial processes like cow horns, hoof-shaped deep roots of the dorsal anchors and a broader shaft of the MCO. Pronotogrammella multifasciatus n. sp. differs from all congeners by having a tubular MCO with twisted shaft and a base with a short and broad arm and by having an almost dumbbell-shaped ventral bar.

Tubificidae (oligochaeta) from the Ross Sea (Antarctica), with descriptions of one new genus and two new species

Three species,Torodrilus gelidus sp. nov. (subfamily Rhyacodrilinae),Rossidrilus terraenovae gen. et sp. nov. (Limnodriloidinae), and a second unnamed species of Limnodriloidinae, are reported from marine sediments in Terra Nova Bay, Ross Sea. Torodrilus gelidus is distinguished fromT. lowryi Cook, 1970 by its setal pattern (with few exceptions, both anterior and posterior setae are single-pointed in sexually mature specimens ofT. gelidus) and the morphology of its male protuberances (the latter folded over a midventral bursa in segment XI).Rossidrilus terraenovae is characterized by large diverticula attached to the oesophagus in the posterior part of segment IX, unpaired male and spermathecal pores, heavily muscular and entally ciliated atrial ampullae, elongate prostatic pads, and a deep, unpaired and muscular, copulatory sac. It is the first species of its subfamily to be described from Antarctic waters.     

Monophyletic origin of Caryophyllia (Scleractinia,Caryophylliidae), with descriptions of six new species

The genus Caryophyllia Lamarck, 1816 is the most diverse genus within the azooxanthellate Scleractinia comprising 66 Recent species and a purported 195 nominal fossil species. Examination of part of the deep-sea scleractinian collection made by the Paris Museum off New Caledonia and part of the material collected by CSIRO off Australian waters revealed the occurrence of 23 species of Caryophyllia, of which six are new to science. All new records, including the new species, are described, and synonyms, distribution, type locality, type material and illustration are provided for each species. An identification key to all Recent species of Caryophyllia is presented. In addition, the validity of the genus Caryophyllia was investigated by phylogenetic analyses of a dataset consisting of partial mitochondrial 16S rRNA sequences from 12 species assigned to this genus together with seven species representing some of the most morphologically similar caryophylliid genera, and 14 non-caryophyllid species representing 14 scleractinian families. Irrespective of the method of analysis employed, all of the Caryophyllia species formed a well-supported clade together with Dasmosmilia lymani and Crispatotrochus rugosus. Although based on a subset of the Recent Caryophyllia species, these results are consistent with Caryophyllia being a valid genus, but call for a reexamination of Dasmosmilia and Crispatotrochus.
