Chauhanellus Bychowsky & Nagibina, 1969 (Monogenea) from ariid fishes (Siluriformes) of Peninsular Malaysia

Twelve new species of Chauhanellus Bychowsky & Nagibina, 1969 have been found on six species of ariid from Peninsular Malaysia: Chauhanellus trifidus n. sp., C. digitalis n. sp., C. malayanus n. sp., C. forcipis n. sp. and C. intermedius n. sp. from Arius sagor; C. aspinous n. sp. from Arius venosus; C. caelatus n. sp. from Arius caelatus; C. auriculatum n. sp., C. poculus n. sp. and C. pulutanus n. sp. from Arius maculatus; C. duriensis n. sp. from Arius thalassinus; and C. osteogeneiosi n. sp. from Osteogeneiosus militaris. Some of these Chauhanellus species possess characteristics that are not commonly observed in the genus. C. aspinous n. sp., C. intermedius n. sp. and C. digitalis n. sp. exhibit features found in both Chauhanellus and Hamatopeduncularia: these include absence of spines on the mainpart of the dorsal anchors in C. aspinous n. sp. and C. intermedius n. sp. and presence of haptoral digitation in C. digitalis n. sp. Other features are the five transverse rows of peduncular spines in C. duriensis n. sp., ear-like projections on the anchors in C. auriculatum n. sp., and thin sclerotised plates that partly envelope the ventral anchors in C. forcipis n. sp. Mid-dorsal appendices occur on the dorsal bars of seven of the present species.     

Miocene ostracods from the Tremiti Islands and Hyblean Plateau: biostratigraphy and description of new and poorly known species

The main taxonomic and stratigraphical results of a study of ostracods from the middle-late Miocene of the Tremiti Islands and the Hyblean Plateau are presented. The faunas are mostly typical of deep thermospheric or psychrospheric bathyal environments. Excluding a few, mostly juvenile shallow water contaminants, a total of 127 species were recorded. Twenty-four taxa are discussed herein; of these, 13 species (Cytherella dissimilis nov. sp., Cytherella parvula nov. sp., Cytherella subtilis nov. sp., Argilloecia triangularis nov. sp., Retibythere (Retibythere)? claudii nov. sp., Retibythere (Retibythere)? gibba nov. sp., Cytheropteron (Cytheropteron) joachinoi nov. sp., Cytheropteron (Aversovalva) consuetum nov. sp., Cytheropteron (Aversovalva) trimerumense nov. sp., Cytheropteron (Aversovalva) turgidum nov. sp., Loxoconcha julianii nov. sp., Buntonia whatleyi nov. sp., Pterygocythere nuda nov. sp.) and a subspecies (Costa tricostata dorsoarcuata nov. subsp.) are described as new, while six are left in open nomenclature. The stratigraphical distribution of ostracods is expressed in terms of planktonic foraminiferal zones. Information obtained from this study enriches biostratigraphical data on Mediterranean Miocene deep-sea ostracods, especially with respect to the Langhian.     

Scaphidiidae (Coleoptera) of Fiji

Abstract

This paper describes 12 new species of Scaphidiidae from Fiji based on a collection made in October 1977 on the two main islands, Viti Levu and Vanua Levu. Three genera and 23 species are now known from Fiji: Baeocera Erichson (parallela n.sp., vanuana n.sp., plana n.sp., ovalis n.sp., kuscheli n.sp., gnava n.sp., ignobilis n.sp., kuscheliana n.sp., reducta n.sp., plus two species left unnamed); Scaphisoma Leach (kuscheli n.sp., liliputanum Löbl, distans Löbl, aequatum Löbl, zimmermani Löbl, debile n.sp., mucronatum n.sp., fijianum Löbl, alienum Löbl); and Scaphoxium Löbl (ventrale Löbl, malekulense Löbl, vitianum Löbl). Keys are given to genera and species.

Diplectanids (Monogenea) on the archerfish Toxotes jaculatrix (Pallas) (Toxotidae) off Peninsular Malaysia

Two new and two previously described species of diplectanid monogeneans (Heteroplectanum flabelliforme n. sp., Diplectanum sumpit n. sp., D. jaculator Mizelle & Kritsky, 1969 and D. toxotes Mizelle & Kritsky, 1969) were collected from archerfish Toxotes jaculatrix off the Island of Langkawi, Kedah and off Perak, Malaysia. The reproductive systems and squamodiscs of D. jaculator and D. toxotes are described for the first time. D. sumpit n. sp. differs from D. toxotes and D. jaculator in a having a small curved copulatory tube with a distinct accessory piece, compared to the long, tubular copulatory tube of D. jaculator and the slender tube of D. toxotes. D. sumpit n. sp. also differs from D. toxotes in having a larger ventral bar and larger squamodiscs. H. flabelliforme n. sp. differs from all known Heteroplectanum species in the shape and size of the squamodiscs, the arrangement of the sclerites in the squamodiscs, the extremely large ventral bar and the short, curved, non-spinous copulatory tube.     

Diversity and distribution of entomopathogenic nematodes (Rhabditida: Steinernematidae and Heterorhabditidae) in Turkey

The diversity and distribution of entomopathogenic nematodes in thefamilies Steinernematidae and Heterorhabditidae were assessed throughout anextensive soil survey in Turkey during 1999 and 2000. Entomopathogenic nematodeswere recovered from six out of seven regions sampled, with 22 positive sites(2%) out of 1080 sites sampled. A single nematode isolate was recovered at eachof the positive sites, of which 15 were steinernematid isolates and seven wereheterorhabditid isolates representing a total of four species. Based onmorphometric and molecular data, the nematode species were identified asHeterorhabditis bacteriophora, Steinernemafeltiae, S. affine, andSteinernema n. sp. The most common species was S.feltiae, which was isolated from 10 sites in six regions, followed byH. bacteriophora from seven sites in five regions,S. affine from four sites in two regions, andSteinernema n. sp. from one site. Heterorhabditisbacteriophora and S. feltiae have been found inmany parts of the world, whereas S. affine, so far, hasonly been recovered in Europe until our survey. Steinernemaaffine was isolated from the European (Marmara) as well as theAsiatic region (Middle Anatolia) of Turkey. A new undescribedSteinernema sp. was isolated from the most eastern region(East Anatolia) of Turkey. Soils of the positive sites were classified as sandy,sandy loam, or loam (68.2%) and sandy–clay–loam or clay loam (31.8%) and the pHranged from 5.6 to 7.9. The habitats from which the entomopathogenic nematodeswere isolated were broadly classified as disturbed (59.1%), which includedagricultural fields and poplar planted for lumber and wind breaks, andundisturbed (40.9%), which included pine forest, grassland, marsh and reed sites.Steinernema feltiae, S. affine, andH. bacteriophora were recovered from both disturbed andundisturbed habitats. The new Steinernema sp. was recoveredfrom grassland. Our survey showed that these nematodes occur widely throughoutTurkey, but at a frequency below that reported for other parts of the world.

Three new species of Dactylogyrus Diesing, 1850 (Monogenea: Dactylogyridae) from the gills of the bala sharkminnow Balantiocheilos melanopterus (Cyprinidae) from Thailand

Three new species of Dactylogyrus are described from the gills of the cyprinid fish Balantiocheilos melanopterus (Bleeker) imported from Thailand via the aquarium trade. They are D. coartatus n. sp., D. macrocolpius n. sp. and D. melanopteri n. sp. The double-bar species, D. coartatus n. sp. and D. melanopteri n. sp., are characterised by hooks that are markedly large in relation to the size of the anchors. Clip-like anchors with a sharply recurved, long point are a unique feature of D. coartatus n. sp. The single-bar species, D. macrocolpius n. sp., is characterised by having a copulatory organ composed of a spiral copulum and a medial accessory piece with thorns.

Morphology and Phylogenetic Position of Two New Gregarine Species (Apicomplexa: Eugregarinorida) Parasitizing the Lubber Grasshopper Taeniopoda centurio (Drury, 1770) (Insecta: Orthoptera: Romaleidae) in Mexico

Eugregarines are understudied apicomplexan parasites of invertebrates inhabiting marine, freshwater, and terrestrial environments. Most currently known terrestrial eugregarines have been described parasitizing the gut from less than 1% of total insect diversity, with a high likelihood that the remaining insect species are infected. Eugregarine diversity in orthopterans (grasshoppers, locusts, katydids, and crickets) is still little known. We carried out a survey of the eugregarines parasitizing the Mexican lubber grasshopper, Taeniopoda centurio, an endemic species to the northwest of Mexico. We described two new eugregarine species from the gut of the host: Amoebogregarina taeniopoda n. sp. and Quadruspinospora mexicana n. sp. Both species are morphologically dissimilar in their life‐cycle stages. Our SSU rDNA phylogenetic analysis showed that both species are phylogenetically distant to each other, even though they parasitize the same host. Amoebogregarina taeniopoda n. sp. clustered within the clade Gregarinoidea, being closely related to Amoebogregarina nigra from the grasshopper Melanoplus differentialis. Quadruspinospora mexicana n. sp. clustered within the clade Actinocephaloidea and grouped with Prismatospora evansi, a parasite from dragonfly naiads. Amoebogregarina taeniopoda n. sp. and Q. mexicana n. sp. represent the first record of eugregarines found to infect a species of the family Romaleidae.     

A taxonomic revision of Labiostrongylus (Labiostrongylus) (Yorke & Maplestone, 1926) and Labiostrongylus (Labiomultiplex) n. subg. (Nematoda: Cloacinidae) from macropodid and potoroid marsupials

The morphological characters used to differentiate species in the genus Labiostrongylus Yorke & Maplestone, 1926, parasitic in macropodid and potoroid marsupials, are discussed. The genus is divided into three subgenera Labiostrongylus (Labiostrongylus), L. (Labiomultiplex) n. subg. and L. (Labiosimplex) n. subg. on the basis of the presence or absence of interlabia and the morphology of the oesophagus. A key to the subgenera is given and a detailed revision of two of the subgenera is presented. Keys to each of the subgenera are given, the species discussed being: L. (L.) labiostrongylus) (type-species) (syn. L. (L.) insularis, L. (L.) grandis, L. (L.) macropodis sp. inq. and L. (L.) nabarlekensis n. sp., in the subgenus Labiostrongylus, and L. (Lm.) eugenii, L. (Lm.) novaeguineae, L. (Lm.) onychogale, L. (Lm.) uncinatus, L. (Lm.) billardierii n. sp., L. (Lm.) constrictis n. sp., L. (Lm.) kimberleyensis n. sp., L. (Lm.) thylogale n. sp., and L. (Lm.) potoroi, n. sp., in the subgenus Labiomultiplex.

Remarkable Rhinophoridae in a growing generic genealogy (Diptera: Calyptratae,Oestroidea)

Four new genera (Apomorphyto gen.n. from Costa Rica, Bixinia gen.n. from Australia, Rhinodonia gen.n. from New Caledonia, Rhinopeza gen.n. from Papua New Guinea) and nine new species (Apomorphyto inbio sp.n. , Bixinia collessi sp.n. , B. solitaria sp.n. , B. spei sp.n. , B. variabilis sp.n. , B. winkleri sp.n. , Rhinodonia antiqua sp.n. , R. flavicera sp.n. , Rhinopeza gracilis sp.n.) of Rhinophoridae (Diptera: Calyptratae, Oestroidea) are described. All new species were included in a morphology‐based phylogenetic analysis to provide arguments for the justification and monophyly (when nonmonotypic) of the new genera and for including these in the Rhinophoridae. The New Caledonian Rhinodonia is a candidate sister taxon to all other rhinophorids, and the Australasian ‘axiniine’ species emerge inside a clade of all Neotropical taxa thus suggesting migration from South America across Antarctica into Australia. This published work has been registered in ZooBank, http://zoobank.org/urn:lsid:zoobank.org:pub:51C1F448‐DDD0‐4F14‐8173‐B8C687F7E841 .

Proatelura jacobsoni Silvestri is recorded in Macao (southern China) and in the Moluccas islands and notes are presented on its male sex. Gastrotheus (Lasiotheus) nanus (Escherich) is found for the very first time in Macao, in Cook islands and in Niue. Identification keys are provided to Protrinemuridae genera and to species of Trinemurodes, and modifications are suggested to previously presented keys to Nicoletiidae genera and to Lepidospora and Metrinura species.     

Taxonomic Revision of the Marine Genus Heterodrilus Pierantoni (Oligochaeta,Tubificidae)1

Marine tubificids possessing trifid anterior setae are morphologically and taxonomically reviewed, on the basis of material from the Atlantic and Pacific Oceans. Heterodrilus Pierantoni, 1902 is revised to include thirteen species, H. arenicolus Pierantoni, 1902, H. minisetosus sp.n.H. ascensionensis sp.n. H. queenslandicus (Jamieson, 1977), H. lacertosus sp.n. H. scitus sp.n. H. keenani sp.n. H. claviatriatus sp.n. H. subtilis (Pierantoni, 1917), H. jamiesoni sp.n. H. occidentalis sp.n. H. pentcheffi sp.n. and H. bulbiporus sp.n. The genus is briefly defined: marine tubificids with trifid setae in preclitellar segments (with H. subtilis as the only exception); paired spermathecae located in segment X; vasa deferentia entering apical, ental ends of slender, ciliated atria, which bear broadly attached masses of prostate glands; paired male pores, and generally with penial setae arranged in bisetal bundles. Heterodriloides gen.n. is established for H. quadrithecatus sp.n. distinguished from Heterodrilus by two main features: its spermathecae are located in XII, with a supplementary pair generally located in XI; and its vasa enter the ectal part of the atria. Giereidrilus gen.n. a third genus with trifid setae, is established to include Phallodrilus ersei Giere, 1979 and G. inermis sp.n. Both species have unpaired spermathecal and male pores, and their atria are not ciliated. Heterodrilus, Heterodriloides and Giereidrilus are placed in the subfamily Rhyacodrilinae Hrabě, 1963.     

A new species of Heth Cobb, 1898 (Nematoda: Rhigonematida: Hethidae) from an Australian millipede (Myriapoda: Diplopoda: Spirostreptida)

Abstract

A new species of nematode, Heth baudini sp. n. from a diplopod (Spirostreptida: Iulomorphidae Verhoeff, 1924) collected in Queensland, Australia, is described and illustrated. The cephalic and cervical cuticular ornamentation of females of H. baudini sp. n. is similar to those of South-East Asian and Australasian Heth species. Heth baudini sp. n. females are particularly close to Heth taynguyeni from Vietnam but can be distinguished by the shape of the lateral lappets, which in H. taynguyeni limit the trapezium-shaped region of smooth cuticle unlike the elliptical region in H. baudini sp. n., and by the presence of lateral spines only half the size. The cuticle of the H. baudini sp. n. is finely annulated along the entire body, whereas H. taynguyeni has broader rings behind the first pair of lateral spines, each consisting of five or six narrower rings separated from each other by deeper furrows. Males of H. baudini sp. n. are characterised by the presence of a bursa-like fold on the tail and can be distinguished from other species of the genus by the presence of somatic papillae embedded into the bursal fold.
