Unravelling the Biodiversity and Molecular Phylogeny of Needle Nematodes of the Genus Longidorus (Nematoda: Longidoridae) in Olive and a Description of Six New Species

The genus Longidorus includes a remarkable group of invertebrate animals of the phylum Nematoda comprising polyphagous root-ectoparasites of numerous plants including several agricultural crops and trees. Damage is caused by direct feeding on root cells as well as by transmitting nepoviruses that cause disease on those crops. Thus, correct identification of Longidorus species is essential to establish appropriate control measures. We provide the first detailed information on the diversity and distribution of Longidorus species infesting wild and cultivated olive soils in a wide-region in southern Spain that included 159 locations from which 449 sampling sites were analyzed. The present study doubles the known biodiversity of Longidorus species identified in olives by including six new species (Longidorus indalus sp. nov., Longidorus macrodorus sp. nov., Longidorus onubensis sp. nov., Longidorus silvestris sp. nov., Longidorus vallensis sp. nov., and Longidorus wicuolea sp. nov.), two new records for wild and cultivate olives (L. alvegus and L. vineacola), and two additional new records for wild olive (L. intermedius and L. lusitanicus). We also found evidence of some geographic species associations to western (viz. L. alvegus, L. intermedius, L. lusitanicus, L. onubensis sp. nov., L. vineacola, L. vinearum, L. wicuolea sp. nov.) and eastern distributions (viz. L. indalus sp. nov.), while only L. magnus was detected in both areas. We developed a comparative study by considering morphological and morphometrical features together with molecular data from nuclear ribosomal RNA genes (D2–D3 expansion segments of 28S, ITS1, and partial 18S). Results of molecular and phylogenetic analyses confirmed the morphological hypotheses and allowed the delimitation and discrimination of six new species of the genus described herein and four known species. Phylogenetic analyses of Longidorus spp. based on three molecular markers resulted in a general consensus of these species groups, since lineages were maintained for the majority of species. This study represents the most complete phylogenetic analysis for Longidorus species to date.

New taxa of Mesorthopteridae (Insecta: Grylloblattida) from the Permian of Russia

New taxa of grylloblattids of the family Mesorthopteridae are described from the Permian of Russia: Parastenaropodites aquilonius sp. nov. from the Soyana locality (Middle Permian); P. circumhumatus sp. nov. from the Kul’chumovo locality; and Tshermyaninus biforis gen. et sp. nov., Permorthopteron foliaceus gen. et sp. nov., Parastenaropodites pannea sp. nov., P. exossis sp. nov., Mesoidelia procera sp. nov., and M. riphaea sp. nov. from the Isady locality (Upper Permian). Two species of the genus Khosaridelia Storozhenko, 1992 (family Permotermopsidae) and one species of the genus Megakhosarina Storozhenko, 1993 (family Megakhosaridae) are transferred to the genus Parastenaropodites Storozhenko, 1996 (family Mesorthopteridae); one species of the genus Parastenaropodites is transferred to the genus Austroidelia Riek, 1954; as a result, four new combinations are established: Khosaridelia rigida Aristov, 2005 =Parastenaropodites rigidus (Aristov, 2005), comb. nov. (Vorkuta locality, Lower Permian of Russia); Khosaridelia vyatica Aristov, 2009 =Parastenaropodites vyaticus (Aristov, 2009), comb. nov. (Karaungir locality, Middle Permian of Kazakhstan); Megakhosarina intricata Aristov, 2008 =Parastenaropodites intricatus (Aristov, 2008), comb. nov. (Soyana locality, Middle Permian of Russia); and Parastenaropodites nervosa Storozhenko, 1996 =Austroidelia nervosa (Storozhenko, 1996), comb. nov. (Madygen locality, Middle Triassic of Kyrgyzstan). An identification key to species of the genus Parastenaropodites is given.     

Dabbling ducks (Aves: Anatidae) from the Middle Miocene of Mongolia

A new genus and two new species of ducks (Aves: Anatidae) from the Middle Miocene Sharga locality are described. Mioquerquedula minutissima gen. et sp. nov. is a very small duck. Anas velox Milne-Edwards, 1868 from the Middle Miocene of France is transferred to the genus Mioquerquedula. Aix praeclara sp. nov. described here is the oldest record of the modern genus Aix. A revision of the previously described small duck Anas soporata Kurochkin, 1976 shows that only the specimens from the Sharga locality should be referred to this species. The status of other small ducks from the Neogene of Europe and North America is discussed. The diversity of herbivorous and diving ducks in the Sharga locality indicates that Miocene Shargyn Govi Lake was rich in food resources.     

The genus Uroleucon (Hemiptera: Aphididae) in the Korean Peninsula,with descriptions of two new species

New damsel-dragonflies with “calopterygid”-like wing shape from the Middle Jurassic of China (Odonata: Isophlebioidea: Campterophlebiidae)

The new damsel-dragonflies Zygokaratawia incompleta nov. sp. and Parazygokaratawia azari nov. gen., nov. sp., closely related to the campterophlebiid genus Zygokaratawia, are described from the Middle Jurassic locality of the Daohugou and Chentaizi villages, respectively (Ningcheng County, Inner Mongolia, NE China). Parazygokaratawia nov. gen. and Zygokaratawia share a narrowly reduced cubito-anal area, unique synapomorphy in the Isophlebioptera. Campterophlebiids with this character are only known from the Daohugou biota.     

Sélaciens nouveaux du London Clay de l'Essex (Yprésien du bassin de Londres)

The Ypresian locality of Burnham-on-Crouch(Essex) has yielded numerous Selachian species, some of which are new: Hexanchus agassizi sp. nov., Scyliorhinus burnhamensis sp. nov., S. casieri sp. nov., S. pattersoni sp. nov., S. woodwardi sp. nov., Pararhincodon ypresiensis sp. nov., Triakis wardi sp. nov., Mustelus whitei sp. nov. The Hexanchid teeth classicaly refered to Notidanus serratissimusAg. include in fact two separate species belonging to different genera: Notorhynchus serratissimus (Ag.) and Hexanchus agassizi sp. nov. Lamna affinis (Casier) is arranged in the genus Isurolamna nov. in consideration of his dental peculiarities. The genus Burnhamia nov. is created for Rhinoptera daviesiWoodward that can be regarded as a Mobulid. Oxyrhina sheppeyensisCasier must be classified in the genus Anomotodon. The genus Triakis, Mustelus, Anomotodon and Pararhincodon are pointed out for the first time in the Ypresian.     

Early Miocene cricetids (Rodentia) from the Junggar basin (Xinjiang, China) and their biochronological implications

Among the 14 small mammal species from the early Miocene locality of the northern area of the Junggar basin (northern Xinjiang, China), four species are cricetids (Rodentia): unnamed species of Cricetodon and Eumyarion, and two new species, Karydomys debruijni nov. sp. and Megacricetodon beijiangensis nov. sp. Some aspects of the morphology of Cricetodon sp. are shared by Eucricetodon from the late Oligocene, suggesting that these specimens could be of intermediate form between Eucricetodon and Cricetodon. One tooth of Eumyarion sp. was found, making its determination uncertain, but its morphology is clearly differentiated from the one of Cricetodon sp. The species K. debruijni nov. sp. is established based on its primitive features compared to the species known in Europe and Anatolia, and its specific association of characters compared to Karydomys dzerzhinskii. M. beijiangensis nov. sp. shows many plesiomorphic features compared to the species already described in the middle Miocene of China. Based on both the whole assemblage of rodents and the species of cricetids, the biochronologic position and the age of the locality are discussed. The locality appears to be biochronologically very close to the fauna from the Chul’adyr Formation in Aktau Mountains, but we propose an age slightly older than the one proposed for this fauna, probably equivalent to the MN3 biozone in Europe.     

Description of five novel thermophilic species of the genus Thermus: Thermus hydrothermalis sp. nov., Thermus neutrinimicus sp. nov., Thermus thalpophilus sp. nov., Thermus albus sp. nov., and Thermus altitudinis sp. nov., isolated from hot spring sediments

Biological denitrification is a significant process in nitrogen biogeochemical cycle of terrestrial geothermal environments, and Thermus species have been shown to be crucial heterotrophic denitrifier in hydrothermal system. Five Gram-stain negative, aerobic and rod-shaped thermophilic bacterial strains were isolated from hot spring sediments in Tibet, China. Phylogenetic analysis based on 16S rRNA gene and whole genome sequences indicated that these isolates should be assigned to the genus Thermus and were most closely related to Thermus caldifontis YIM 73026^T, and Thermus brockianus YS38^T. Average nucleotide identity (ANI) and digital DNA-DNA hybridization (dDDH) values between the five strains and the type strains of the genus Thermus were lower than the threshold values (95% and 70%, respectively) recommended for bacterial species, which clearly distinguished the five isolates from other species of the genus Thermus and indicated that they represent independent species. Colonies are circular, convex, non-transparent. Cell growth occurred at 37–80 °C (optimum, 60–65 °C), pH 6.0–8.0 (optimum, pH 7.0) and with 0–2.0% (w/v) NaCl (optimum, 0–0.5%). Denitrification genes (narG, nirK, nirS, and norB genes) detected in their genomes indicated their potential function in nitrogen metabolism. The obtained results combined with those of morphological, physiological, and chemotaxonomic characteristics, including the menaquinones, polar lipids, and cellular fatty acids showed that the isolates are proposed as representing five novel species of the genus Thermus, which are proposed as Thermus hydrothermalis sp. nov. SYSU G00291^T, Thermus neutrinimicus sp. nov. SYSU G00388^T, Thermus thalpophilus sp. nov. SYSU G00506^T, Thermus albus sp. nov. SYSU G00608^T, Thermus altitudinis sp. nov. SYSU G00630^T.     

Discovery of the genus Skidmorella Johnson (Coleoptera: Ptiliidae) in Japan, with descriptions of two new species

The genus Skidmorella Johnson, previously known only from the South Pacific islands, is discovered in Japan. The type species, Skidmorella magnifica Johnson, is confirmed from Japan as the first record of the species other than the type locality. In addition, two new species, Skidmorella amamiana sp. nov. and Skidmorella quadrisulucia sp. nov., are described from the Ryukyus, Japan. Phylogenetic relationships of the genus Skidmorella and its allies are discussed on the basis of their morphological characters.

Parablastocatena tetracerae gen. et sp. nov. and Corynesporella licualae sp. nov., collected on dead branches of Tetracera asiatica and Licuala fordiana, respectively, in tropical forests of China, are described and illustrated. Parablastocatena tetracerae is the type species for a new monotypic genus in possessing macronematous conidiophores forming distinct synnemata with holoblastic conidiogenesis and euseptate, short-chained conidia ending in a paler brown rostrum, whereas C. licualae is distinguished from described species by the smaller conidia with long appendages. A key to currently accepted species of Corynesporella is provided.

Species delimitation in the Andean grasshopper genus Orotettix Ronderos & Carbonell (Orthoptera: Melanoplinae): an integrative approach combining morphological,molecular and biogeographical data

The reciprocal illumination nature of integrative taxonomy through hypothesis testing, corroboration and revision is a powerful tool for species delimitation as more than one source has to support the hypothesis of a new species. In this study, we applied an integrative taxonomy approach combining molecular and morphological data sets with distributional patterns to examine the level of differentiation between and within the grasshopper Orotettix species. Orotettix was described based on five valid species distributed in the Andes of Peru. In our study, initially a molecular‐based hypothesis was postulated and tested against morphological data and geographical patterns of distribution. Results from molecular and morphological analyses showed agreement among the species delimitation in Orotettix, and were also consistent with the geographical distribution. The analyses allowed us to delimit five new species for the genus ( O. lunatus sp. nov. , O . astreptos sp. nov. , O. colcaensis sp. nov. , O . paucartambensis sp. nov. and O . dichrous sp. nov. ) from the Eastern and Western Cordilleras of Peru. We also provide critical knowledge on the phylogenetic relationships and distribution of the genus and conduct a revision of Orotettix. © 2015 The Linnean Society of London     

Cuvillierinella salentina (Foraminifera,Rhapydioninidae) and its kinship in the Western Mediterranean area during the Campanian–Maastrichtian

Cuvillierinella salentina Papetti and Tedeschi, 1965 and its related species of the Rhapydioninidae family are widely distributed in the Western Mediterranean region by Campanian–Maastrichtian time. C. salentina, the type species of the genus, is studied in rich populations from its Italian type locality, and several other spots from Greece and Spain. It shows great variability: the well-known type coexists with streptospiral tests almost devoid of endoskeleton and wholly planispiral tests with fine mesh-like endoskeleton, as well as many intermediates. Such populations reflect the large capacity of evolution of at least the group of miliolids from which these populations are derived, if not the species itself. The genera Murciella and Cyclopseudedomia are probably the most direct offshoots, but other taxa appear to arise from this species or at least from the same stock of origin. In the same genus and at the same time (middle part of Campanian age, “CsB6a” zone), two new species are described, both hesitating between the streptospiral and planispiral coiling: – C. fluctuans nov. sp., from Greece, A tests being either streptospiral or planispiral, with primary and secondary chamberlets taking the aspect of polygonal isodiametric network and – C. perisalentina nov. sp., from Italy, with persistent streptospiral coiling and disordered arrangement of secondary chamberlets which allow us to consider its relation with species of the genus Pseudochubbina, hitherto of completely enigmatic origin. Assigned to the same genus, from Upper Campanian–Lower Maastrichtian time (“CsB6b” zone), C. aff. pylosensis, probably related to C. pylosensis, is studied from several populations, and constitutes, with the above mentioned species, what is called C. gr. salentina. Based on material from the CsB6b zone, the new genus Metacuvillierinella nov. gen. is introduced; M. decastroi nov. sp., type species of the new genus, known from Greece and Italy, shows characters common to C. gr. salentina, such as milioline to streptospiral nepionic coiling, large endoskeleton mesh, associated with some original characters, such as the unusual conjunction of the advolute coiling and absence of any final unrolling together with very low dimorphism of generation; this results in flat tests, often sigmoid shaped in axial section, very rare in the family. Thus, the genus Cuvillierinella, and especially C. salentina, appears as a possible source, or at least not far from the origin, of a number of taxa related to one another, constituting a large part of the Rhapydioninidae family. They are gathered together inside the new subfamily Cuvillierinellinae, distinct from the subfamily Rhapydionininae sensu stricto (comprising Rhapydionina and Fanrhapydionina) which makes a different and parallel branch, from Upper Campanian (CsB6b zone) to the end of Cretaceous time (CsB7 zone).     

Ichneumon wasps of the Khasurty locality in Transbaikalia (Insecta, Hymenoptera, Ichneumonidae)

One new genus and four new species of ichneumon wasps are described from the Lower Cretaceous of Buryatia (Khasurty locality): Amplicella mininae, sp. nov., A. shcherbakovi, sp. nov., A. bashkuyevi, sp. nov., Khasurtella buriatica, gen. et sp. nov. The species Tanychora sinensis Zhang, 1991 is transferred to the new genus Khasurtella. Similarity of the ichneumonid faunas of Khasurty and the Chinese localities Yixian and Laiyang indicates the age similarity between these localities. Identification key to genera and species of Tanychorinae is given.     

Proptychopterina (Diptera: Eoptychopteridae) from the Jurassic of Northeastern China

A complete well-preserved male fly from the Jurassic of Daohugou locality (Northeastern China) is described as Proptychopterina opinata sp. nov. The distribution of Proptychopterina is discussed, this genus is re-diagnosed, and a key to species is provided based on the wings.     

Diversimorbus metrosiderotis gen. et sp. nov. and three new species of Holocryphia (Cryphonectriaceae) associated with cankers on native Metrosideros angustifolia trees in South Africa

The Cryphonectriaceae includes important tree pathogens, especially on the Myrtales. During a routine disease survey in the Western Cape Province of South Africa, a fungus resembling the Eucalyptus pathogen Holocryphia eucalypti was observed on native Metrosideros angustifolia (Myrtales). The aims of this study were to identify the fungus and to expand surveys for fungi in the Cryphonectriaceae on M. angustifolia. Fungi were identified based on DNA sequence comparisons and morphological features, and their pathogenicity was tested on M. angustifolia under field conditions. Based on morphology and multigene phylogenetic analyses of DNA sequence data from six gene regions, we describe a new genus including a single species and three new species of Holocryphia (Cryphonectriaceae) from M. angustifolia. These fungi are provided with the names Diversimorbus metrosiderotis gen. et sp. nov., Holocryphia capensis sp. nov., Holocryphia gleniana sp. nov., and Holocryphia mzansi sp. nov. We also revise H. eucalypti, the type of the genus, to include only isolates from Eucalyptus in South Africa. Research results indicated that H. mzansi may undergo host shifts between different tree genera in the Myrtaceae. Inoculation tests showed that isolates of all the newly described species can cause lesions on the branches of M. angustifolia, indicating that they are all pathogens of this tree.
