Three new species of Euathlus Ausserer, 1875 (Araneae,Theraphosidae) from Argentina

ABSTRACT

Euathlus

Ausserer, 1875 is a South American genus of spiders of the family Theraphosidae known from Chile and Argentina. Three new species from Argentina: Euathlus mauryi sp. n. (from San Juan province), Euathlus grismadoi sp. n. (from La Rioja province), and Euathlus pampa sp. n. (from Salta province) are described here. New records of the previous species Euathlus diamante and Euathlus tenebrarum are contributed. The distribution of these new species expands the geographical distribution of the genus along the Andean hills, with Salta province as the northernmost record of the genus. A key is provided for identification of Euathlus species as well as a map with all the records in Argentina.     

Two New Species of the Weevil Subgenus Pseudotiorhynchus Magnano,Genus Otiorhynchus Germ. (Coleoptera,Curculionidae: Entiminae) from Iran

Two new species of the subgenus Pseudotiorhynchus Magnano, 2004 of the genus Otiorhynchus Germar, 1822 are described from Iran: O. demavendussp. n. from Mount Demavend and O. binaludussp. n. from the Binalud Range.

     

Two new species of Monogenea of the genus Pseudodiplectanum tripathi, 1955, branchial parasites of Galeoides decadactylus,a teleostean from the coasts of Gabon

Summary Two new monogenean species have been studied: Pseudodiplectanum megacirrus n.sp. and P. spinosum n.sp., branchial parasites of Galeoides decadactylus (Bloch, 1795) (Teleostei, Polynemidae) from the coasts of Gabon. P. megacirrus is characterized by the large size of its cirrus and P. spinosum has an haptoral peduncle armed with strong spines.Comparison of these species with those already described allows a more precise definition of the genus.     

<Emphasis Type="Italic">Decacotyle cairae</Emphasis> n. sp. (Monogenea: Monocotylidae) from the gills of <Emphasis Type="Italic">Pastinachus</Emphasis> sp. (Elasmobranchii: Dasyatidae) from the South China Sea off Sarawak,Borneo, Malaysia

Decacotyle cairae n. sp. (Monogenea: Monocotylidae) is described from the gills of an unidentified species of Pastinachus collected in the South China Sea off Sematan and Mukah, Sarawak, Borneo, Malaysia. D. cairae can be distinguished from the other six members of the genus by the presence of two simple unsclerotised accessory structures on the dorsal surface of the haptor in combination with a long, narrow, looping male copulatory organ. The host specimens of Pastinachus collected in Borneo also appear to be a new species and the monogenean data support this conclusion. A key to species of Decacotyle is given and their host-specificity is discussed.     

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.     

Kiwialges haastii n. sp., a feather mite (Acari: Analgidae) from the great spotted kiwi,Apteryx haastii Potts, 1872 (Aves: Apterygidae); with a key to species of Kiwialges,and new host records

Abstract

A new species of feather mite (Acari: Analgidae), Kiwialges haastii n. sp. is described from the great spotted kiwi, Apteryx haastii Potts, 1872. Four new host records are reported and a key to species of Kiwialges is presented.     

A new parasitic copepod (Cyclopoida: Bomolochidae) from a ponyfish (Leiognathidae) caught in Egyptian Mediterranean waters,with a review of hosts and key to species of Nothobomolochus

A new bomolochid copepod belonging to the genus Nothobomolochus Vervoort, 1962 is described from a Red Sea fish species, a ponyfish of the family Leiognathidae that has become established in the Eastern Mediterranean. The new species, N. leiognathicola n. sp., is based on material obtained from the gill chamber of the Red Sea immigrant ponyfish Leiognathus klunzingeri (Steindachner), caught in Egyptian waters off the Alexandria coast at Abuqir. A second new species, N. monodi n. sp., is established to accommodate some material previously described as N. denticulatus (Bassett-Smith, 1898), from the host Hemiramphus far Forsskål. A review of host records reveals that Nothobomolochus species utilise hosts representing five different orders, but are most commonly found on beloniform, clupeiform and perciform fishes. A newly constructed key to the 37 valid species of Nothobomolochus is presented.     

Zelandoperla maungatuaensis sp. n. (Plecoptera: Gripopterygidae), a new flightless stonefly species from Otago,New Zealand

ABSTRACT

A new wing-reduced species of the stonefly genus Zelandoperla Tillyard is described from Otago, New Zealand. Zelandoperla maungatuaensis sp. n. differs from a related species, Z. denticulata, primarily by lacking full wing development. We used morphological, geographical, and genetic evidence to assess the proposed status of Z. maungatuaensis sp. n. and Z. denticulata as separate monomorphic species, as opposed to conspecific members of a polymorphic species. High genetic divergence was found between distinctly allopatric populations, supporting the status of Z. maungatuaensis sp. n. as a distinct monomorphic species.

Abstracts of papers and posters presented at the 33rd conference of the New Zealand society for Parasitology,at Massey University,Palmerston North, 24 October 2006

Abstract

Eight species of Recent Braohiopoda dredged from the fiords of south-western New Zealand in 1946 included first records for Fiordlarrd of Crania, Amphithyris, and Liothyrella. Amphithyris richardsonae n.sp. is described from a live-collected individual from 74 m, Long Sound, Preservation Inlet; it differs from A. buckmani Thomson and A. hallettensis Foster in shape, attachment, and details of ornament. Ventml valves fTom 101 m, Dagg Sound, characterised by coarse punctation and an ornament of hollow spines are treated as Platidiidae genus and species indeterminate.     

A new species of nematode parasite,Cucullanus tunisiensis sp. nov. (Nematoda: Cucullanidae) from Epinephelus aeneus (Perciformes: Serranidae) off Tunisia

Cucullanus tunisiensis sp. nov., (Nematoda: Cucullanidae), collected from the intestine of the white grouper Epinephelus aeneus from waters off the coast of Tunisia is described based on light and scanning electron microscopic observations. The new species is characterized by the presence of lateral alae, ventral sucker, long unequal spicules (left spicule 2474-2789 μm long, right spicule 2357-2518 μm long). This is the sixth nominal species of the genus Cucullanus Müller, 1777 and the first representative of this genus infecting fishes of Serranidae family reported from Tunisian waters.

     

Three new species of Philocorydoras Suriano, 1986 (Monogenoidea: Dactylogyridae) infecting the gills of callichthyids (Actinopterygii: Callichthyidae) from the Peruvian Amazonia

During a research on gill ectoparasites of callichthyids fishes from the Peruvian Amazonia, the following monogenoideans were found: Philocorydoras peruensis n. sp. from Corydoras splendens (Castelnau); Philocorydoras multiradiatus n. sp. and Philocorydoras jumboi n. sp. from Brochis multiradiatus (Orcés, V.). All new species described herein are mainly differentiated from their congeners based on the morphology of the copulatory complex. In P. peruensis n. sp. the cirrus is “J”-like shaped tube slightly tilted to one side, while in P. jumboi n. sp. is “J”-like shaped tube in a straight position and in P. multiradiatus n. sp. the cirrus is an arced tube with inflated base and distally narrow. Brochis (Orcés, V.) represents a new genus hosting species of Philocorydoras. All new species presented in this work represent the first species of Philocorydoras reported for Peru.

     

New genera,species and records of rhinebothriidean cestodes (Platyhelminthes) parasitic in Australian stingrays (Elasmobranchii: Batoidea)

Collections of rhinebothriidean cestodes (Platyhelminthes) from Australian batoid elasmobranchs revealed the presence of a number of new genera and species. Ruptobothrium louiseuzeti n. g., n sp. is described from the reticulate whipray, Himantura australis Last, Naylor & Manjaji-Matsumoto, from off the Northern Territory and Mixobothrium queenslandense n. g., n sp. is described from the green sawfish, Pristis zijsron Bleeker, from off north-eastern Queensland. Two new species of Rhabdotobothrium Euzet, 1953 are described: Rhabdotobothrium meridionale n. sp. from the southern eagle ray Myliobatis tenuicaudatus Hector from off South Australia and Rhabdotobothrium anoxypristidis n. sp. from the narrow sawfish, Anoxypristis cuspidatus (Latham) from off north Western Australia. A new species of Scalithrium Healy & Reyda, 2016, Scalithrium australiense n. sp., is described from the reticulate whipray, Himantura australis Last, Naylor & Manjaji-Matsumoto, from off northern Western Australia. Scalithrium smitii (Shinde, Deshmukh & Jadhav, 1981) n. comb. is reported from Australian waters for the first time in the black spotted stingray Maculabatis toshi (Whitley) from off northern Western Australia. New host and geographical records are provided for Stillabothrium jeanfortiae Forti, Aprill & Reyda, 2016 from the brown whipray Maculobatis toshi (Whitley) and the black-spotted whipray, Maculabatis cf. astra (Last, Manjaji-Matsumoto & Pogonoski) from Moreton Bay in southern Queensland.

     

<Emphasis Type="Italic">Malalophus jensenae</Emphasis> n. g., n. sp. (Monogenea: Monocotylidae) from the gills of <Emphasis Type="Italic">Aetomylaeus vespertilio</Emphasis> (Myliobatidae) off northern Australia

Malalophus jensenae n. g., n. sp. is described from the gills of the ornate eagle ray Aetomylaeus vespertilio (Bleeker) collected off the eastern coast of the Gulf of Carpentaria, northern Queensland. The new genus is similar to Heliocotyle Neifar, Euzet & Ben Hassine, 1999, with which it shares a haptor bearing seven peripheral loculi and a single dorsal haptoral accessory structure. M. jensenae can be distinguished from species of Heliocotyle by the presence of numerous sclerotised sinuous ridges covering the ventral surfaces of the peripheral loculi of the haptor. It also lacks pseudosepta which are present on the haptor of Heliocotyle species. This is the first published record of a monogenean from an elasmobranch in the Gulf of Carpentaria, Australia.     

Two new species of <Emphasis Type="Italic">Cotingacola</Emphasis> Carriker,Phthiraptera: Ischnocera: Philopteridae) from Amazonian Brazil,with comments on host-specificity

This paper describes two new species of Cotingacola Carriker, 1956, C. lutzae n. sp. and C. engeli n. sp., from the cinereous mourner Laniocera hypopyrra (Vieillot) and black-necked red cotinga Phoenicircus nigricollis Swainson (Aves: Passeriformes: Cotingidae), respectively. These species are fully illustrated and compared with their morphologically closest relatives. With the addition of these two new species, this Neotropical chewing louse genus now includes ten species. We also present records from Brazil for two previously described species, C. stotzi Clayton & Price, 1998 and C. parmipapillae Carriker, 1956. The re-examination of a specimen identified as ‘Cotingacola sp.’ in a recent phylogenetic study confirmed that it is C. parmipapillae and that Querula purpurata (Statius Müller) regularly hosts two Cotingacola species, which means that at least three cotingid hosts carry more than one species of Cotingacola. We comment on the variability in the host-specificity of Cotingacola species.     

Sexually dimorphic body proportions in the catshark genus Scyliorhinus (Chondrichthyes: Carcharhiniformes: Scyliorhinidae)

Intersexual differences in morphometrics were investigated in five species of the catshark genus Scyliorhinus. ANCOVA was used to test 59 measurements, considering capture location and total length as covariates. In all examined species, pelvic–anal distances and pelvic-fin inner margin lengths were greater in males than in females, representing a clear pattern for the genus.     

Calicotyle australiensis n. sp. and Calicotyle sp. (Monogenea,Monopisthocotylea) from the rectum and rectal glands,and Rugogaster hydrolagi Schell, 1973 (Trematoda,Aspidogastrea) from the rectal glands of holocephalans off the coast of southeastern Australia

Calicotyle australiensis n. sp. from Chimaera sp., caught off the coast of New South Wales, is described. It differs from the other species of the genus in the combination of the following characteristics: length of the penis-tube, absence of medial diverticula of the caeca and presence of hamuli. Calicotyle sp. from Rhinochimaera pacifica and Rugogaster hydrolagi from Chimaera sp. caught at the same locality are reported and illustrated.

     

A new species of Branchellion Savigny, 1822 (Hirudinida: Piscicolidae), a marine leech parasitic on the giant electric ray Narcine entemedor Jordan & Starks (Batoidea: Narcinidae) off Oaxaca,Mexico

Branchellion spindolaorum n. sp. (Hirudinida: Piscicolidae) is described based on specimens found parasitising the giant electric ray Narcine entemedor Jordan & Starks off the coast of Oaxaca, Mexico. The new species can be clearly distinguished from the other species of Branchellion Savigny, 1822 by the presence of 30 pairs of lateral branchiae and 10 pairs of pulsatile vesicles. The definition of the genus Branchellion is expanded to include species with either 30, 31 or 33 pairs of foliaceous (plate-like) lateral branchiae in the urosome. In addition, we provide for the first time for the genus, scanning electron micrographs of the secondary suckers located on the ventral surface of the posterior sucker. Additionally, partial DNA sequences of the mitochondrial cytochrome c oxidase subunit 1 (cox1) were generated and compared with homologous sequences of other species of the genus. Branchellion spindolaorum n. sp. represents the fourth species of the genus known in the Eastern Pacific and the first record of a leech parasitising N. entemedor.
