Taxonomic notes on the genus Mastax Fischer von Waldheim, 1828 (Coleoptera: Carabidae: Brachininae) in Korea

A widespread East Asian species, Mastax poecila Schaum, 1863 is recorded in Korea for the first time, to which previous record of M. thermarum egorovi Lafer, 1973 (Paik & Kim, 2006) is assigned. Mastax formosana Dupis, 1912 from Taiwan is proposed as a junior synonym of M. poecila.     

Taxonomic Limits of the Genus Nagelus (Thorne and Malek, 1968 Siddiqi, 1979 with a Description of Nagelus borealis n.sp. from Alaska

The genus Nagelus (Thorne and Malek, 1968) Siddiqi, 1979 is modified and a new species from Alaska is described. The combination of scanning electron microscopy and light microscopy permits the characterization of Nagelus spp. as having a broadly oval face pattern, no longitudinal striations on the lip region, deirids surrounded by six incisures, and an irregularly tapering tail with a large hyaline region. Nagelus leptus (Allen, 1955) Siddiqi, 1979, N. alpensis Doucet and Luc, 1981, N. camelliae (Kheiri, 1972) Siddiqi, 1979, N. jamelensis (Nesterov, 1973) Siddiqi, 1979, and N. obscurus (Allen, 1955) n. comb. are retained on this basis. Nagelus borealis n. sp. is characterized by a styler length of 30 μm or more, an irregularly scalloped perioral disc, and a proportionately larger basal bulb. Nagelus abalosi (Doucet, 1978) Doucet. 1980 and N. virginalis (Doucet, 1978) Doucet, 1980 are synonymized with N. leptus. Nine other species from Nagelus are transferred to Merlinius Siddiqi, 1970.

Epsilonematidae (Nematoda) from Chiloé (southern Chile), with descriptions of two new species

From a sandy beach in southern Chile (Quellón Viejo, Chiloé Island) five species of the nematode family Epsilonematidae are described or redescribed: Bathyepsilonema spongiosum sp.n., Epsilonema dentaturn Lorenzen, 1973, E. serrulatum Lorenzen, 1973, Metepsilonema chilotum sp.n. and M. leptaleum Lorenzen, 1973. In the studied beach Epsilonematidae represent up to 33% of the interstitial nematodes. Epsilonema dentaturn is the most common species; in most of the samples, it represents more than 50% of all Epsilonematidae found. The epsilonematids occur mainly in a narrow zone at the midtidal level.     

Revision of Microlaimidae, Erection of Molgolaimidae fam.n., and Remarks on the Systematic Position of Paramicrolaimus (Nematoda, Desmodorida)

The family Microlaimidae contains Bolbolaiminae subfam.n. (Bolbolaimus syn. Pseudomicro-laimus) and Microlaiminae ( Calomicrolaimus, Ixonema and Microlaimus ). The new family Molgolaimidae contains Aponematinae subfam.n. ( Aponema gen.n.) and Molgolaiminae subfam.n. ( Molgolaimus and Prodesmodora ). The main differentiating characters applied are: structures of the head region, shape of the oesophagus, position of the excretory pore, shape of the tail, structure of the gonads and ornamentation of the cuticle. The significance of porids and preanal supplements as distinguishing characters is, discussed. Microlaimidae are closely related to Desmodoridae; Molgolaimidae related to Spiriniidae. Paramicrolaimus is transferred from Microlaimidae to Spiriniidae.–Six species from the Øresund, Denmark, are redescribed: Microlaimus punctulatus Gerlach, 1950 and M. acinaces Warwick & Piatt, 1973; Aponema torosus (Lorenzen, 1973) gen.n., comb.n. (syn. Microlaimus torosus Loren-zen, 1973); Molgolaimus allgeni (Gerlach, 1950) comb.n. (syn. Microlaimus allgeni Gerlach, 1950) and M. turgofrons (Lorenzen, 1972) comb.n. (syn. Microlaimus turgofrons Lorenzen, 1972); Paramicrolaimus spirulifer Wieser, 1959.     

Taxonomic revision of Joyeuxilepis Spassky, 1947 (Cestoda: Amabiliidae): redescriptions of J. biuncinata (Joyeux & Baer, 1943), J. decacantha (Fuhrmann, 1913) and J. pilatus Borgarenko & Gulyaev, 1991

Two species of Joyeuxilepis Spassky, 1947 are redescribed from Tachybaptus ruficollis in Bulgaria: J. biuncinata (Joyeux & Baer, 1943) and J. pilatus Borgarenko & Gulyaev, 1991. The syntypes of J. decacantha (Fuhrmann, 1913) from Podiceps cristatus in Sweden and voucher specimens of J. pilatus (identified as 'Tatria decacantha') from T. ruficollis in England (new geographical record) from the British Museum (Natural History) Collection are also re-described. The voucher specimens and cysticercoids of Tatria spp. from dragonfly nymphs in Wales recorded by Rees (1973) were re-examined. Previous records of J. biuncinata, J. decacantha and J. pilatus are critically analysed in view of the present results. The major reliable diagnostic characters for species of Joyeuxilepis are presented and the distinguishing criteria for the three species studied are re-evaluated.

SEM Observations on the Marine Nematode Dracognomus simplex (Gerlach, 1954) Allen and Noffsinger, 1978 (Draconematidae: Prochaetosomatinae)

The free-living marine nematode Dracognomus simplex (Gerlach, 1954) Allen &Noffsinger, 1978 was studied by scanning electron microscopy (SEM). The morphology of males and females is described and illustrated in detail. In addition to the typical and modified adhesion tubes, a new type of posterior adhesion tube was discovered. A neotype is proposed for Dracognomus simplex, and D. simplex sensu Decraemer &Gourbault, 1986 is renamed as Dracognomus americanum n. sp. Additionally, a key toward the Dracognomus species is proposed.     

Revision of Neotropical Metopia Meigen (Diptera: Sarcophagidae)

ABSTRACT. The Neotropical species of Metopia Meigen are revised, and a total of fifteen species recorded from the region. Five species are described as new; M.aurigans sp.n., M.pulverulenta sp.n., M.hispidimana sp.n., M.flava sp.n., and M.cubitosetigera sp.n. Three species are recorded for the first time from the Neotropical region; M.inermis Allen, 1926, M.krombeini Sabrosky, 1953, and M.sinipalpis Allen, 1926. Four new synonyms are proposed; M.tessellata Allen, 1926, syn.n. of M.perpendicularis Wulp, 1890, M.macrocera Dodge, 1968, syn.n. of M.brasiliana (Townsend, 1929), M.astuta Dodge, 1968, syn.n. of M.brasiliana (Town-send, 1929), and M.lucipeda Reinhard, 1961, syn.n. of M.campestris (Fallen, 1810). Males of M.polita (Townsend, 1935) and M.juquiana (Townsend, 1934) are recorded for the first time. A key to all American species of Metopia is provided, and the phylogenetic affinities of the Neotropical species are briefly discussed.     

Draconematidae (Nematoda) from cold-water corals in the Porcupine Seabight: The genus Cygnonema Allen & Noffsinger, 1978

Two new and closely related species of the genus Cygnonema Allen & Noffsinger, 1978 are described from a cold-water coral degradation zone in the Porcupine Seabight (NE Atlantic). Both species differ from C. steineri Allen & Noffsinger, 1978 by more pronounced pharyngeal and posterior swellings, a smaller body, a shorter pharynx in relation to body length, a higher number of CAT, and by the absence of a dorsal tooth. Cygnonema verum sp. n. differs from C. belgicae sp. n. by its greater body length, the relatively larger head capsule, a higher number of CAT, a more anteriorly positioned anteriormost laterodorsal CAT, a higher number of PAT, by the external labial sensilla being setiform, a higher number of subcephalic setae, and by a more anterior position of the amphidial fovea on the head capsule. Males of C. verum sp. n. are easily recognised by the presence of two large subventral, precloacal corniform setae. They also differ from males of C. belgicae sp. n. in the smaller amount of cytoplasm in the sperm cells, a knob-like capitulum, and a relatively shorter tail tip. The diagnosis of Cygnonema is emended, a dichotomic identification key to the three species is provided, and their biogeography is discussed.     

A new species,new host records and life cycle data for lepocreadiids (Digenea) of pomacentrid fishes from the Great Barrier Reef,Australia

A new species of lepocreadiid, Opechonoides opisthoporus n. sp., is described infecting 12 pomacentrid fish species from the Great Barrier Reef, Australia, with Abudefduf whitleyi Allen & Robertson as the type-host. This taxon differs from the only other known member of the genus, Opechonoides gure Yamaguti, 1940, in the sucker width ratio, cirrus-sac length, position of the testes, position of the pore of Laurer’s canal, and relative post-testicular distance. The new species exhibits stenoxenic host-specificity, infecting pomacentrids from seven genera: Abudefduf Forsskål, Amphiprion Bloch & Schneider, Neoglyphidodon Allen, Neopomacentrus Allen, Plectroglyphidodon Fowler & Ball, Pomacentrus Lacépède and Stegastes Jenyns. Phylogenetic analyses of 28S rDNA sequence data demonstrate that O. opisthoporus n. sp. forms a strongly supported clade with Prodistomum orientale (Layman, 1930) Bray & Gibson, 1990. The life cycle of this new species is partly elucidated on the basis of ITS2 rDNA sequence data; intermediate hosts are shown to be three species of Ctenophora. New host records and molecular data are reported for Lepocreadium oyabitcha Machida, 1984 and Lepotrema amblyglyphidodonis Bray, Cutmore & Cribb, 2018, and new molecular data are provided for Lepotrema acanthochromidis Bray, Cutmore & Cribb, 2018 and Lepotrema adlardi (Bray, Cribb & Barker, 1993) Bray & Cribb, 1996. Novel cox1 mtDNA sequence data showed intraspecific geographical structuring between Heron Island and Lizard Island for L. acanthochromidis but not for L. adlardi or O. opisthoporus n. sp.

     

Mathevotaenia niuguiniensis n. sp. (Cestoda: Anoplocephalidae: Linstowiinae) from the water-rat Parahydromys asper (Thomas) in Papua New Guinea, with a list of species of Mathevotaenia Akumyan, 1946

A new species of cestode, Mathevotaenia niuguiniensis n. sp. (Anoplocephalidae: Linstowiinae), is described from the hydromyine rodent Parahydromys asper (Thomas) in Papua New Guinea. This is the third species of the genus reported from the Australasian region. The new species differs from all congeners in rodents by having an elongate cirrus-sac, which crosses the osmoregulatory canals and extends into the medulla, compared with a short, ovoid cirrus-sac which does not penetrate into the medulla in congeners. It differs from the known Australian species, M. antechini (Beveridge, 1977) and M. nyctophili (Hickman, 1954), found in dasyurid marsupials and bats respectively, by lacking a complex of anastomosing osmoregulatory canals in each segment. A list of all known species of Mathevotaenia Akumyan, 1946, their host genera, host families and geographical distribution is provided. New combinations proposed in this report are: M. dipodomi (Bienek & Grundmann, 1973) n. comb. (transferred from Schizorchodes Bienek & Grundman, 1973), M. genettae (Ortlepp, 1937) n.comb., M. mephitis (Skinker, 1935) n. comb., M. pedunculata (Chandler, 1952) n. comb., M. wallacei (Chandler, 1952) n. comb. (transferred from Oschmarenia Spasskii, 1951) and M. oedipomidatis (Stunkard, 1965) n. comb. (transferred from Paratriotaenia Stunkard, 1965).     

A new species of Pseudanisakis Layman & Borovkova, 1926 (Nematoda: Ascaridida) from Rioraja agassizii and Psammobatis extenta (Rajidae) in Brazilian southwestern Atlantic waters

Pseudanisakis sulamericana n. sp. is described from the intestines of the rays Rioraja agassizii and Psammobatis extenta off the coast of Brazil. It can be readily differentiated from the three existing species of the genus. From P. tricupola Gibson, 1973, it differs in not having cupolas on the lips, having a dentigerous ridge of 90-95 denticles ( vs 65-78) in a continuous subtriangular ring around the mouth, and in having an ejaculatory duct which is shorter than the spicules. From P. rajae (Yamaguti, 1941), it differs in having a single rather than a double row of denticles. It appears most similar to P. baylisi Gibson, 1973, but differs from it in having a smaller body-size (7.5-27 vs 16-46 mm), shorter spicules (1.14-1.90 vs 1.90-3.80 mm) and especially in having much more conspicuous denticles on the lips. The present record confirms the presence of the genus in subtropical waters.

Three new species of picobiine mites (Acari: Syringophilidae) parasitising African flycatchers (Aves: Muscicapidae)

Three new species of quill mites of the subfamily Picobiinae Johnston & Kethley, 1973 (Acari: Syringophilidae) are described from African flycatchers (Passeriformes: Muscicapidae): Picobia cichladusa n. sp. on Cichladusa arquata Peters and P. myrmecocichla n. sp. on Myrmecocichla arnotti (Tristram), both from Tanzania, and P. echo n. sp. on Cossypha heuglini Hartlaub from the Democratic Republic of the Congo.     

A catshark (Neoselachii, Carcharhiniformes, Scyliorhinidae) from the Late Jurassic of Germany

A new genus and species of catshark (Neoselachii, Carcharhiniformes, Scyliorhinidae) —Bavariscyllium tischlingeri n. gen. n. sp. — is described from the Late Jurassic (Tithonian) Plattenkalke of South Germany. The new taxon is known from a single articulated skeleton having the skull, the trunk and all of the fins preserved. The position of the first dorsal fin in relation to the pelvic fins and the dental morphology shows that the specimen belongs into the neoselachian family Scyliorhinidae. Two isolated tooth crowns from the Kimmeridgian of North Germany are identified asBavariscyllium sp. and represent the oldest unambigious fossil record of the Scyliorhinidae known so far.     

New and revised maimetshid wasps from Cretaceous ambers (Hymenoptera, Maimetshidae)

New material of the wasp family Maimetshidae (Apocrita) is presented from four Cretaceous amber deposits - the Neocomian of Lebanon, the Early Albian of Spain, the latest Albian/earliest Cenomanian of France, and the Campanian of Canada. The new record from Canadian Cretaceous amber extends the temporal and paleogeographical range of the family. New material from France is assignable to Guyotemaimetsha enigmatica Perrichot et al. including the first females for the species, while a series of males and females from Spain are described and figured as Iberomaimetsha Ortega-Blanco, Perrichot & Engel, gen. n., with the two new species Iberomaimetsha rasnitsyni Ortega-Blanco, Perrichot & Engel, sp. n. and Iberomaimetsha nihtmara Ortega-Blanco, Delclòs & Engel, sp. n.; a single female from Lebanon is described and figured as Ahiromaimetsha najlae Perrichot, Azar, Nel & Engel, gen. et sp. n., and a single male from Canada is described and figured as Ahstemiam cellula McKellar & Engel, gen. et sp. n. The taxa are compared with other maimetshids, a key to genera and species is given, and brief comments made on the family.
