The Brachymeria tibialis species group is newly recognized and diagnosed together with the Brachymeria annulata, femorata, kassiliensis and lasus species groups also newly defined. In these diagnoses a few morphological characters of the ventral part of the mesosoma, discovered in this study, are proposed to help differentiate the groups. The B. tibialis species group itself includes solely B. tibialis (Walker) and B. zygaenae Delvare & Shaw n. sp., which was until now mixed with it. The biology and hosts of both species are summarized.

International audience; Thylacocephala is an enigmatic ingroup of Euarthropoda. Th ylacocephalans, only known from Pal-aeozoic and Mesozoic fossils, are characterized by a particular anatomy: a prominent folded shield enveloping most of the body, large compound eyes, three pairs of large, presumably raptorial ap-pendages and a trunk with 8-22 stout segments bearing swimming appendages. However, lifestyle(s) and phylogenetic relationships of Th ylacocephala are still largely unknown. Th is study is focused on thylacocephalans from the Mazon Creek Lagerstätte (c. 307 Ma, Middle Pennsylvanian, Carbonifer-ous). A new species is described from a siderite concretion of Mazon Creek: Eodollocaris keithfl intin. gen., n. sp. Th e new species displays a particular mixture of characters typical for Palaeozoic species on the one hand and Mesozoic species on the other hand. Additionally, new details of the appendages and of the trunk are provided for already known species from the same locality, namely Concavicaris georgeorum Schram, 1990 and Convexicaris mazonensis Schram, 1990. Th ese new informations are helpful to better understand the possible lifestyle of these representatives of Th ylacocephala; Une nouvelle espèce de thylacocéphale (Eodollocaris keithfl inti n. gen., n. sp.) du Lagerstätte de Mazon Creek, Illinois, États-Unis (c. 307 Ma) et re-description des autres thylacocéphales de Mazon Creek.Les thylacocéphales forment un groupe interne énigmatique d’Euarthropoda. Les thylacocéphales, seulement connus au Paléozoïque et au Mésozoïque, se caractérisent par une anatomie particulière : une carapace bivalve enveloppant la majorité du corps, de larges yeux composés, trois larges paires d’appendices préhensiles présumés et un tronc avec 8 à 22 segments corpulents portant des appendices nageurs. Cependant, le(s) mode(s) de vie et les relations phylogénétiques des thylacocéphales restent encore majoritairement inconnus. Cette étude se concentre sur les thylacocéphales du Lagerstätte de Mazon Creek (c. 307 Ma, Pennsylvanien moyen, Carbonifère). Une nouvelle espèce est décrite à partir d’une concrétion sidéritique de Mazon Creek : Eodollocaris keihtfl inti n. gen., n. sp. La nouvelle espèce présente un mélange particulier de caractères typiques des espèces paléozoïques d’un côté et d’espèces mésozoïques de l’autre. De plus, de nouveaux détails sur les appendices et sur le tronc sont donnés pour des espèces déjà connues de la même localité, à savoir Concavicaris georgeorum Schram, 1990 et Convexicaris mazonensis Schram, 1990. Ces nouvelles informations sont utiles pour mieux comprendre le mode de vie possible de ces thylacocéphales.

International audience; The ponerine ant Anochetus miosumatrensis Ngô-Muller, Garrouste & Nel, n. sp. is described from a fossil alate female preserved in amber of Sumatra which is reputedly of Miocene age. On the basis of the general morphology, the fossil could be attributed to the extant Sumatran species group risii Brown, 1978. By comparing with the living environment of the extant species, this ant probably lived in a warm humid forest where it was trapped in dipterocarpacean resin during nuptial flight. Until now, the known Cenozoic distribution of the genus Anochetus was restricted to the Neotropi-cal region. Thus A. miosumatrensisNgô-Muller, Garrouste & Nel, n. sp. brings the first record of the genus from Indomalaya biogeographic region.; La première fourmi du genre Anochetus Mayr, 1861 de l’ambre néogène de Sumatra (Hymenoptera: Formicidae).La fourmi ponérine Anochetus miosumatrensis Ngô-Muller, Garrouste & Nel, n. sp. est décrite à partir d’une femelle fossile ailée, conservée dans l’ambre de Sumatra, réputée d’âge Miocène. Sur la base de la morphologie, le fossile pourrait être attribué à l’espèce actuelle du groupe risii Brown, 1978 de Sumatra. Par comparaison avec l’environnement de vie de l’espèce actuelle, cette fourmi a probablement vécu dans une forêt chaude et humide, où elle a été piégée dans une résine diptérocarpacéenne pendant le vol nuptial. Jusqu’à présent, la distribution cénozoïque connue était restreinte à la zone néotropicale. Ainsi, A. miosumatrensis Ngô-Muller, Garrouste & Nel, n. sp. fournit le premier enregistrement du genre dans la zone indo-malaisienne.

Fourteen species of Chalcidoidea (Encyrtidae, Eulophidae, Eupelmidae, Eurytomidae, Pteromalidae and Torymidae) were obtained from the common reed, Phragmites australis (Cav.) Trin. ex Steud. (Poaceae) in the Urmia region, in the northwest of Iran. Among these species, two new species of Pteromalidae are described hereafter: Norbanus persicus Lotfalizadeh & Rasplus sp. nov. and Stenomalina delvarei Lotfalizadeh & Rasplus sp. nov. Anagyrus near alienus Japoshvili, 2002, Asitus sp., Cheiloneurus paralia (Walker, 1837), Echthroplexiella obscura (Hoffer, 1952), Neococcidencyrtus poutiersi (Mercet, 1922) (all Encyrtidae), Aprostocetus orithyia (Walker, 1839) (Eulophidae), Eupelmus phragmitis Erdös, 1955 (Eupelmidae), Aximopsis deserticola (Zerova, 2004) comb. nov., Tetramesa phragmitis (Erdös, 1952) and Tetramesa sp. (all Eurytomidae), Homoporus febriculosus (Girault, 1917) (Pteromalidae) and Torymus arundinis (Walker, 1833) (Torymidae) were also obtained from our laboratory rearing. Nine of these species are recorded for the first time from Iran.

International audience; Phlyctinus callosus (Schoenherr, 1826) (Curculionidae, Entiminae, Oosomini) is a species native to the Western Cape province of the Republic of South Africa. It is regarded as a key pest of orchards and vineyards. Detailed observations of its morphology and ecology have shown this species to be a complex of closely related species. In this study we describe the species of this complex, provide morphological and molecular diagnostic tools to distinguish between species, and review their distribution and host plant associations. In all, six species are recognized in the P. callosus complex and five are described as new (P. grootbosensis Haran sp. nov., P. xerophilus Haran sp. nov., P. planithorax Haran sp. nov., P. littoralis Haran sp. nov., P. aloevorus Haran sp. nov.). Sequences of the mitochondrial gene used (cytochrome oxidase I, COI) indicated that P. xerophilus Haran sp. nov. might comprise several cryptic species for which stable morphological features could not be identified at this stage. The species of the genus Phlyctinus appear to be primarily associated with various Asteraceae found in humid, sandy and disturbed habitats.

Bartonella mastomydis sp. nov. strain 008 is the type strain of B. mastomydis sp. nov., a new species within the genus Bartonella. This strain was isolated from Mastomys erythroleucus rodents trapped in the Sine-Saloum region of Senegal. Here we describe the features of this organism, together with the complete genome sequence and its annotation. The 2 044 960 bp long genomes with 38.44% G + C content contains 1674 protein-coding and 42 RNA genes, including three rRNA genes. Keywords: Bartonella mastomydis sp. nov., complete genome, Mastomys erythroleucus, rodents, Senegal

Coleoptera Histeridae from French Guiana. IX. A new species of the genus Operclipygus Marseul, 1870 (Histerinae, Exosternini). A new species, Operclipygus dogueti n. sp., is described from one specimen collected by a flight interception trap in French Guiana. It belongs to the informal group of Operclipygus sulcistrius. It is distinguished from other species in the group by its dorsal striation, the surface sculpture of its pronotum, and its more elongated form., Une espèce nouvelle, Operclipygus dogueti n. sp., est décrite à partir d’un exemplaire récolté au piège d’interception de vol en Guyane française. Cette espèce appartient au groupe informel d’Operclipygus sulcistrius. Elle se distingue des autres taxons du groupe par sa striation élytrale, la sculpture de surface de son pronotum et sa forme plus allongée., Degallier Nicolas. Coleoptera Histeridae de Guyane. IX. Une nouvelle espèce du genre Operclipygus Marseul, 1870 (Histerinae, Exosternini). In: Bulletin de la Société entomologique de France, volume 123 (2),2018. pp. 193-196.

During previous surveys of helminths in rodents from Southeast Asia, an unnamed species of Aonchotheca was recovered from the stomach of several rodent species. In the present study, the description of the new species Aonchotheca yannickchavali n. sp. is provided based on both female and male specimens collected from two bandicoot rat species (Bandicota indica and Bandicota savilei) from Thailand (Buriram and Nan provinces). This nematode can be separated from other known Aonchotheca found in rodents by its microhabitat in the host and by the size of the spicules in males and the vulvar appendage in females.

International audience; La riche faune de vertébrés d’Aumelas a été le sujet depuis plusieurs décennies de diverses publications partielles qui avaient conduit à lui assigner un âge voisin du niveau-repère MP 13 dans l’échelle biochronologique de mammifères d’Europe de l’Ouest. Mais elle reste encore partiellement inédite et cet article fait partie d’une révision générale de la faune. En ce qui concerne les périssodactyles équoïdes, cinq taxons ont été distingués, que l’on attribue à des « Pachynolophinae » à l’exclusion de tout Palaeotheriinae. Deux espèces sont prédominantes dans ce groupe : Propalaeotherium sudrei Remy, Krasovec & Marandat, 2016 et Pachynolophus ruscassierensis n. sp. Les trois autres taxons sont moins bien documentés, ce qui empêche leur détermination spécifique, Pachyno­lophus sp., Propalaeotherium cf. gaudryi (Lemoine, 1878) et Lophiotherium sp. L’ensemble de ces espèces présente des caractéristiques relativement archaïques, mises en lumière grâce à une analyse cladistique. Une telle conclusion remet en question le consensus jusqu’ici en vigueur sur la datation de la faune, dans le sens d’un âge biochronologique plus ancien. Cette discordance sera analysée dans un travail synthétique ultérieur, en conjonction avec les spécialistes des différents ordres de mammifères et de reptiles représentés dans la localité.

The paleobiogeographic range of Eofavartia Merle, 2002 (Gastropoda: Muricidae) was until now restricted to the Eocene (Ypresian to Priabonian) of the North Atlantic Ocean and the genus seemed to become extinct after the Priabonian. The description of E. dharmai nov. sp. from the Middle Miocene from Java (Indonesia) reveals the persistence of Eofavartia during the Neogene in the Indo-Pacific region. In addition, the critical reexamination of three South Australian species previously attributed to Murexiella and Subpterynotus respectively: M. perculta Vokes, 1985 (Lower Miocene), S. antecedens (Ludbrook 1958) (Pliocene) and S. tatei (Verco 1895) (Recent) shows closer morphological affinities to E. dharmai nov. sp. and the European and North American Paleogene species of Eofavartia. The generic reassignment to Eofavartia expands the range of the genus to include South Australia. The extant E. tatei represents the last member of the genus, and is herein considered a relict species of Eofavartia.

International audience; The Alps are a hotspot of biodiversity in Europe with many Lepidoptera species still to be discovered. Here we describe a new gracillariid genus and species, Mercantouria neli gen. n. and sp. n. The morphology of the male genitalia is highly differentiated with unique features. DNA barcodes show that its nearest neighbor is the North American species ‘Caloptilia’ scutellariella (Braun, 1923). M. neli is known from four adults (two males and two females) collected at two localities in the French Alps. Its host plant and life cycle remain unknown.

This paper provides new taxonomic and biological data on a complex of gracillariid moths in the endemic genus Philodoria Walsingham, 1907 that are associated with Myrsine (Primulaceae) in the Hawaiian Islands, United States. Two new species, Philodoriakauaulaensis Kobayashi, Johns & Kawahara, sp. n. (host: Myrsinelanaiensis, M.lessertiana, and M.sandwicensis) and P.kolea Kobayashi, Johns & Kawahara, sp. n. (host: M.lessertiana) are described. Biological data are provided for two previously described species that also feed on Myrsine: P.auromagnifica Walsingham, 1907 and P.succedanea Walsingham, 1907. For the first time we detail and illustrate genital structures, immature stages, biology, and host plants of P.auromagnifica and P.succedanea. Philodoriakolea, P.auromagnifica, and P.succedanea occur in sympatry on the island of Hawaii (Big Island), but each species differs in behavioral characters: P.kolea utilizes leaves of seedlings and forms a serpentine mine, whereas the latter two utilize leaves of larger plants, and form linear or serpentine to blotch mines. More broadly, leaf mine forms and diagnostic characteristics of the Myrsine-feeding species complex of Philodoria (as currently known) are reviewed and illustrated.

We describe a new vanilla species growing in sympatry with Vanilla planifolia Jacks. ex Andrews (Orchidaceae) in the province of Limón, Caribbean coast of Costa Rica. The morphology of the reproductive and vegetative organs observed on vines cultivated under shade-house, the nuclear (Internal Transcribed Spacer) and plastid (matK) nucleotide sequences, as well as the contents of aromatic compounds measured in ripe fruits, show that this species is close to but distinct from V. planifolia. The name V. sotoarenasii M.Pignal, Azofeifa-Bolaños & Grisoni sp. nov. is proposed for this new Vanilla species endemic in Costa Rica. It is especially distinguished from V. planifolia by a reduction of about 30% of the size of the fruits and flowers, by a divergence of ITS sequences for at least two species-conserved nucleotides compared to seven other species of the V. planifolia group, and by the presence of anisic compounds and low content of phenolic compounds (including vanillin) in the fruits. These results confirmed the extension of the area of distribution of V. planifolia southward to Costa Rica, where a recent speciation process occurred. Because of its particular agronomic and aromatic properties, V. sotoarenasii sp. nov. could represent a valuable biological resource for the vanilla industry. Describimos una nueva especie de vainilla que crece en simpatía con Vanilla planifolia Jacks. ex Andrews (Orchidaceae) en la provincia de Limón, costa caribeña de Costa Rica. La morfología de los órganos reproductores y vegetativos observados en vides cultivadas bajo sombra, las secuencias nucleotídicas nucleares (Internal Transcrito Spacer) y plastidios (matK), así como el contenido de compuestos aromáticos medidos en frutos maduros, muestran que esta especie es cercano pero distinto de V. planifolia. El nombre V. sotoarenasii M. Pignal, Azofeifa-Bolaños & Grisoni sp. nov. Se propone para esta nueva especie de vainilla endémica en Costa Rica. Se distingue especialmente de V. planifolia por una reducción de aproximadamente el 30% del tamaño de los frutos y flores, por una divergencia de secuencias de ITS para al menos dos especies de nucleótidos conservados en comparación con otras siete especies del grupo de V. planifolia. , y por la presencia de compuestos anísicos y bajo contenido de compuestos fenólicos (incluida la vainillina) en los frutos. Estos resultados confirmaron la extensión del área de distribución de V. planifolia hacia el sur hasta Costa Rica, donde ocurrió un reciente proceso de especiación. Por sus particulares propiedades agronómicas y aromáticas, V. sotoarenasii sp. nov. podría representar un valioso recurso biológico para la industria de la vainilla. Descrevemos uma nova espécie de baunilha que cresce em simpatia com Vanilla planifolia Jacks. ex Andrews (Orchidaceae) na província de Limón, costa caribenha da Costa Rica. A morfologia dos órgãos reprodutivos e vegetativos observados em vinhas cultivadas à sombra, as sequências de nucleotídeos nucleares (espaçador de transcrição interno) e plastídeos (matK), bem como o conteúdo de compostos aromáticos medidos em frutos maduros, mostram que esta espécie está próxima, mas diferente de V. planifolia. O nome V. sotoarenasii M. Pignal, Azofeifa-Bolaños & Grisoni sp. Nov. É proposto para esta nova espécie endêmica de baunilha na Costa Rica. É especialmente distinta de V. planifolia por uma redução de aproximadamente 30% no tamanho de frutos e flores, por uma divergência de sequências ITS para pelo menos duas espécies de nucleotídeos conservados em comparação com outras sete espécies do grupo V. planifolia. , e pela presença de compostos anísicos e baixo teor de compostos fenólicos (incluindo vanilina) nos frutos. Esses resultados confirmaram a extensão da área de distribuição de V. planifolia ao sul até a Costa Rica, onde ocorreu um recente processo de especiação. Devido às suas propriedades agronômicas e aromáticas particulares, V. sotoarenasii sp. Novembro pode representar um valioso recurso biológico para a indústria de baunilha.

International audience; The species of the Afrotropical genus Afrosmicronyx Hustache (Curculionidae, Curculioninae, Smicronychini), biocontrol agents of parasitic plants in crops (Striga, Orobanchaceae), are revised. Ten species are recognized, two of them described as new (A. mirei Haran, sp. n. and A. madagascariensis Haran, sp. n.). A key to the species with photographs of the habitus and male genitalia of type specimens is provided.

A new scleractinian coral species, Pachyseris inattesa sp. n., is described from the Red Sea. Despite a superficial resemblance with some species in the agariciid genus Leptoseris with which it has been previously confused, P. inattesa sp. n. has micro-morphological characters typical of the genus Pachyseris. This genus, once part of the Agariciidae, is comprised of five extant species and is widely distributed throughout the tropical Indo-Pacific. It is currently incertae sedis as a result of recent molecular analysis and appears to be closely related to the Euphylliidae. A molecular phylogenetic reconstruction including P. inattesa sp.n., the genus type species P. rugosa, and P. speciosa, all present in the Red Sea, was performed using the mitochondrial intergenic spacer between COI and 16S-rRNA. The results confirm that P. inattesa sp. n. is a monophyletic lineage closely related to the other Pachyseris species examined.

Tetramelus, from Pyrénées-Orientales (Coleoptera, Staphylinidae, Scydmaeninae). A new cave-dwelling species of ant-like stone beetle of the genus Euconnus Thomson, 1859, subgenus Tetramelus Motschulsky, 1869, E. (T.) tronqueti n. sp., is described from the cave Sainte-Marie (Pyrénées-Orientales, France). The relationship of this new species with E. (T.) bazgoviensis Vít & Hlaváč, 2005, and E. (T.) longipedes Hlaváč & Jalžić, 2009, the only real cavernicolous Tetramelus known from the palaearctic fauna, is briefly discussed. Some comments on the endogean species of Tetramelus from the Pyrenean mountains are provided., Une espèce hypogée nouvelle de Scydménide du genre Euconnus Thomson, 1859, sous-genre Tetramelus Motschulsky, 1869, E. (T.) tronqueti n. sp., est décrite de la grotte Sainte-Marie (Pyrénées-Orientales, France). Ses affinités avec E. (T.) bazgoviensis Vít & Hlaváč, 2005, et E. (T.) longipedes Hlaváč & Jalžić, 2009, seuls Tetramelus cavernicoles avérés connus jusqu’à présent de la région paléarctique, sont discutées. Quelques commentaires sur les espèces endogées de Tetramelus de la chaîne des Pyrénées sont également fournis., Orousset Jean.

This is the first description of full genome sequences of chickpea chlorotic dwarf virus (CpCDV; genus Mastrevirus; family Geminiviridae) identified in papaya and tomato plants sampled in Burkina Faso. The CpCDV full genome sequences from papaya and tomato share the highest pairwise sequence identity (84% and 93.5%) with Sudanese isolates of the CpCDV-K and CpCDV-M strains, respectively. Based on the strain demarcation threshold (>94% identity) for mastreviruses, we propose two new strains, CpCDV-Q and CpCDV-R, identified in papaya and tomato, respectively. Phylogenetic analysis confirmed that the sequences belong to a distinct clade of the highly diverse population of CpCDVs. Evidence of inter-strain recombination provided more support for the important role of recombination in CpCDV evolution. The discovery of CpCDV on papaya, a previously unsuspected host, raises many questions about the natural and potential host range of this dicot-infecting mastrevirus species that is reported to be emerging worldwide.

In this report, we present the first description of the complete genome sequence of a new monopartite begomovirus isolated from tomatoes collected in Burkina Faso and presenting with symptoms of tomato leaf curl disease. We propose the tentative name “tomato leaf curl Burkina Faso virus'' (ToLCBFV). DNA-A-like nucleotide sequence of ToLCBFV shares the highest nucleotide sequence identity (85%) with the pepper yellow vein Mali virus (PepYVMLV). Phylogenetic analysis confirmed the affiliation of ToLCBFV to Old World monopartite begomoviruses. This discovery of a new species confirms the existence of high genetic diversity in monopartite begomoviruses in sub-Saharan Africa and particularly in West Africa.

Hypogeous Coleoptera from Corsica. XLV. The collection of Roger Pelleterat de Borde (Coleoptera Bothrideridae, Carabidae, Staphylinidae, Zopheridae). -Study of the endogeous Coleoptera preserved in the collection of Roger Pelleterat de Borde in the "Centre de Conservation et d'Étude des Collections" of Musée des Confluences in Lyon (France) : 23 species are enumerated. A new species of Staphylinidae Pselaphinae, Mayetia (Mayetia) bordei n. sp., is described.

Passiflora kapiriensis is a new Guianese species in the series Laurifoliae of subgenus Passiflora, found near Saint-Georges-de-l'Oyapock. The filaments of the fourth corona row are 1 cm long and oriented to the androgynophore, which is reminiscent of P. acuminata, P. cerasina, P. fissurosa, P. killipiana and P. nitida. It differs from these close relatives by the combination of subequal first and second rows of filaments, a very short hypanthium, very long petioles, with medial nectary glands, and much larger leaves.

The Moroccan Phylan belonging to the subgenus Meladeras Mulsant et Rey, 1854 are revised. Phylan (Meladeras ) marocanus Obenberger, 1914 is reinstated as a valid species, Phylan (Meladeras) ferreri sp. n. is described and Phylan (Meladeras) barbarus (Lucas, 1846) is excluded of Moroccan fauna. A key to the three Moroccan species is provided., Nous révisons ici la représentation marocaine des Phylan appartenant au sous-genre Meladeras Mulsant et Rey, 1854. Phylan (Meladeras ) marocanus Obenberger, 1914 est rétabli comme espèce valide, Phylan (Meladeras) ferreri sp. n. est décrit et Phylan (Meladeras) barbarus (Lucas, 1846) est exclu de la faune marocaine.

International audience; Polychelidan lobsters (Crustacea: Decapoda) are abundant in the celebrated Middle Jurassic (Callovian)Lagerstätte of La Voulte-sur-Rhône (Ardèche, France). Among them, Eryon giganteus Van Straelen, 1923,is recognized by its large, rounded carapace. The generic assignment of this species has been particularlycomplicated, with many conflicting assignments proposed since the first description of the species. Thepresent study reinvestigates E. giganteus following the rediscovery of its lectotype. Careful examinationsreveal that the type material is composite: the lectotype belongs to a species of eryonid that wasdescribed recently as Cycleryon romani Audo, Schweigert, Saint Martin & Charbonnier, 2014, and isquite rare (six specimens); the rest of the material, and most specimens formerly assigned to E. giganteuscorrespond to an abundant species of Proeryon Beurlen, 1928 (33 specimens) that we herein describeas Proeryon charbonnieri n. sp. The present study also allows us to reinvestigate the generic assignmentof E. giganteus. Detailed observations allowed assigning E. giganteus to Soleryon Audo, Charbonnier,Schweigert & Saint Martin, 2014 based upon: the grooves marked across the dorsal part of carapace; aposterior carina near the posterior margin; and a hepatic carina between cervical and hepatic grooves.This taxonomic revision also leads to abandon Proeryon zehentbaueri, the replacement name whichwas proposed for Proeryon giganteus Beurlen, 1930.; Les Polychelida (Crustacea: Decapoda) sont abondants dans le célèbre Lagerstätte Jurassique moyen (Callovien) de La Voulte-sur-Rhône (Ardèche, France). Parmi eux, Eryon giganteus Van Straelen, 1923, est reconnaissable à sa grande carapace arrondie. L’assignation générique de cette espèce a été particulièrement complexe, de nombreuses assignations génériques contradictoires ayant été proposées. La présente étude révise cette espèce suite à la redécouverte de son lectotype. Un examen attentif du matériel type démontre qu’il est composite : le lectotype appartient à une espèce d’eryonidé assez rare (six spécimens connus) avec laquelle Cycleryon romani Audo, Schweigert, Saint Martin & Charbonnier, 2014 est mis en synonymie ; le reste du matériel type et la plupart des spécimens précédemment assignés à E. giganteus correspondent à une nouvelle espèce de Proeryon Beurlen, 1928 assez abondante (33 spécimens), ici nommée Proeryon charbonnieri n. sp. La présente étude nous permet également de résoudre l’assignation générique d’E. giganteus. Cette espèce est assignée à Soleryon Audo, Charbonnier, Schweigert & Saint Martin, 2014 en raison de ses sillons marqués sur toute la face dorsale de la carapace, sa carène postérieure près de la marge postérieure de la carapace et sa carène hépatique visible entre le sillon cervical et hépatique. Ces actes taxonomiques impliquent également l’abandon du nom de remplacement Proeryon zehentbaueri, qui avait été proposé pour Proeryon giganteus Beurlen, 1930.

Metrosideros Banks ex Gaertner (1788: 170, Myrtaceae) is one of the most widespread tree genus across the Pacific islands and is an emerging model for the study of speciation in tropical trees (Papadopulos et al. 2011; Stacy et al. 2014). The material housed at the Muséum National d’Histoire Naturelle in Paris (P) was recently reviewed in order to prepare the evaluation of the New Caledonian species for the IUCN redlist (IUCN 2017) and apply some recent taxonomic changes in the genus (Pillon et al. 2015). A new species from Vanuatu came to light and is described below.

A new righteye flounder, Poecilopsetta multiradiata, is described from eight specimens (two males and six females) collected from deep waters (336–408 m) around New Zealand and New Caledonia (South-West Pacific). This new species is distinguished from its 14 congeners by the following combination of characters: high numbers of dorsal (70–73) and anal (58–62) fin rays, ca. 85–99 lateral-line scales, 31–32 caudal vertebrae, and a relatively shallow body depth of 36.9–41.9% SL.

Colchicum verlaqueae Fridlender : a new endemic Colchicum from Sardinia Field studies show us that five Colchicum species occur in Sardinia. C. actupii and C. gonarei are endemic. C. multiflorum and C. cupanii are widespread throughout West Mediterranean countries. The fifth one, C. verlaqueae sp. nov. was erroneously named C. corsicum Baker., Trois colchiques endémiques vivent en Sardaigne : C. gonarei décrit en 1978, C. actupii décrit en 1999 et enfin C. verlaqueae Fridlender sp.nov. précédemment confondu avec C. corsicum Baker.

Xanthomonas albilineans is the bacterium responsible for leaf scald, a lethal disease of sugarcane. Within the Xanthomonas genus, X. albilineans exhibits distinctive genomic characteristics including the presence of significant genome erosion, a non-ribosomal peptide synthesis (NRPS) locus involved in albicidin biosynthesis, and a type 3 secretion system (T3SS) of the Salmonella pathogenicity island-1 (SPI-1) family. We sequenced two X. albilineans-like strains isolated from unusual environments, i.e., from dew droplets on sugarcane leaves and from the wild grass Paspalum dilatatum, and compared these genomes sequences with those of two strains of X. albilineans and three of Xanthomonas sacchari. Average nucleotide identity (ANI) and multi-locus sequence analysis (MLSA) showed that both X. albilineans-like strains belong to a new species close to X. albilineans that we have named “Xanthomonas pseudalbilineans”. X. albilineans and “X. pseudalbilineans” share many genomic features including (i) the lack of genes encoding a hypersensitive response and pathogenicity type 3 secretion system (Hrp-T3SS), and (ii) genome erosion that probably occurred in a common progenitor of both species. Our comparative analyses also revealed specific genomic features that may help X. albilineans interact with sugarcane, e.g., a PglA endoglucanase, three TonB-dependent transporters and a glycogen metabolism gene cluster. Other specific genomic features found in the “X. pseudalbilineans” genome may contribute to its fitness and specific ecological niche.

The present study compares all known species of Cylindrocladium that have clavate vesicles. Several isolates were obtained from baited soils collected in various parts of the world, while others were associated with leaf litter or symptomatic plant hosts. Isolates were compared based on morphology, as well as DNA sequence data from their β-tubulin and histone gene H3 regions. Cylindrocladium australiense and Cy. ecuadoriae, are described as new species, a decision based on morphology and molecular data. A group of isolates associated with toppling disease of banana in the West Indies is identified as Cy. flexuosum. An epitype is designated for Cy. ilicicola, and a new name, Curvicladiella, proposed to replace the anamorphic genus Curvicladium, which is a homonym.Taxonomic novelties: Cylindrocladium australiense Crous& K.D. Hyde sp. nov., Cylindrocladium ecuadoriae Crous & M.J. Wingf. sp. nov., Curvicladiella Decock & Crous nom. nov., Curvicladiella cignea (Decock & Crous) Decock & Crous comb. nov.

A disc-shaped methanogenic bacterium designated strain SEBR 4847T (T = type strain) was isolated from a sample collected from an African offshore oil field. Strain SEBR 4847T was non-motile, had a G + C content of 50 mol% and produced methane from H2 + CO2, formate, and CO2 + propanol. Strain SEBR 4847T grew optimally at 37 degrees C; no growth was observed at 25 degrees C or 45 degrees C. It grew in the presence of up to 50 g/l NaCl; 10-30 g/l was required for optimal growth. The optimum pH for growth was 7.0. Doubling time was about 10 h under optimal conditions. Based on 16S rRNA sequence analysis, the isolate was identified as a new species of the genus Methanoplanus and designated Methanoplanus petrolearius sp. nov. The type strain is SEBR 4847T (= OCM 486).

Cicadalna takensis, n. gen., n. sp. discovered in northwestern Thailand (Rhynchota, Cicadidae). The diagnosis of a new genus of tribe Cicadini from the Tak's province (N.W. of Thailand) is given. Then, typical species, Cicadalna takensis n. gen., n. sp. is described, as well as a particular morpha, and first illustrated indications about its sound ethology are brought ; also its ID acoustic card is established., Un nouveau genre de Cicadines, Cicadalna n. gen., découvert dans la province de Tak (N.O. thaïlandais) est décrit, ainsi que son espèce-type, Cicadalna takensis n. sp., avec une morphe particulière.

Six isolates recovered from coffee seeds giving off a potato-like flavour were studied. Gene sequencing (rrs and rpoB) showed they belong to the genus Pantoea . By DNA–DNA hybridization, the isolates constituted a genomic species with less than 17 % relatedness to 96 strains representing enterobacterial species. Multilocus sequence analysis (gyrB, rpoB, atpD and infB genes) showed the isolates to represent a discrete species of the genus Pantoea . Nutritional versatility of the novel species was poor. The novel species is proposed as Pantoea coffeiphila sp.nov. and its type strain is Ca04T ( = CIP 110718T = DSM 28482T).

Four species of monocotylid monogeneans were found on a spotted eagle ray Aetobatus cf. narinari caught off Noumea, New Caledonia, South Pacific. The host is illustrated for future possible identification, because it belongs to a currently unresolved species complex. Decacotyle octona (Young, 1967) ChisholmWhittington, 1998, from the secondary gill lamellae, is figured and previously unreported details of the reproductive system are described. D. elpora n. sp. is described from numerous specimens found between the secondary gill lamellae. The new species, 780-1650 microm in body length, is smaller than D. octona, but has a longer sclerotised male copulatory organ. It is characterised by two dorsal haptoral accessory structures, each with three bumps, and a 9-shaped sclerotised male copulatory organ 240-290 microm in length. D. octona and Clemacotyle australis Young, 1967, both from the branchial cavity, and Thaumatocotyle pseudodasybatis Hargis, 1955, from the nasal tissue, are new geographical records for New Caledonia. It is suggested that differences in the monocotylid fauna between the Atlantic and Indo-Pacific forms of Aetobatus cf. narinari could be of interest for the systematic status of the ray, but the sporadic nature of the sampling probably casts doubt on the usefulness of the currently available data.

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.

Psalitrus aberlenci n. sp., a new Omicrini from Guinea (Coleoptera, Hydrophilidae). Psalitrus aberlenci n. sp., a new Sphaeridiinae Omicrini, is described from Guinea. The new species is closely related to Ps. durisi Bameul and lives on water films under wet stones. Characters of both species are compared. Six morphometric characters are compared using a new robust form of Hotelling' s T2 test. A discriminant function is computed using randomised discriminant analyses., Psalitrus aberlenci n. sp., Sphaeridiinae Omicrini nouveau, est décrit de Guinée. La nouvelle espèce, aux mœurs pétrimadicoles, est proche de Ps. durisi Bameul. Les caractères distinctifs des deux espèces sont décrits. Pour les séparer, six caractères morphométriques sont comparés à l'aide d'une nouvelle variante robuste du test T2 de Hotelling. Une fonction discriminante est calculée par analyse discriminante randomisée., Bameul Franck. Psalitrus aberlenci n. sp., nouvel Omicrini de Guinée (Coleoptera, Hydrophilidae).

Two new species (Hemiptera, Fulgoromorpha, Cixiidae) included in a new genus, Meenocixius gen. n., and associated with Acanthophoenix rubra (Bory) H. Wendl. (Arecaccae) are described from the island of La Reunion: M bebourensis sp. n. and M. virescens sp. n. This genus shows several autapomorphies in its tegmina venation, very particular within the Fulgoromorpha. Borbonomyndus gen. n., is proposed for another new species, B. pandanicola sp. n. associated with Pandanus purpurascens Thouars (Pandanaceae), and B. pallidus (Synave), previously described as a member of the genus Eumyndus Synave. According to morphological and ethological data, E. bistriatus is synonymized with B. pallidus, of which three different forms are recognized. All species of Borbonomyndus are found associated with Pandanus. These two new genera are endemic to La Reunion. Without taxonomic standing, the subspecies of Brixia belouvensis are synonymyzed and restricted to four different forms. A key is proposed for the Cixiidae of La Reunion, which now includes 12 species belonging to 6 different genera: Achaemenes, Aselgeoides, Brixia, Oliarus (but we show that the species placed in this genus need to be reviewed), Borbonomyndus, and Meenocixius. Monophyly of Eumyndus, from which E. perinetensis Synave is excluded, is substantiated. Following the new interpretation, this genus is now restricted to Madagascar. The species Cubana insularis Muir, from the island of Rodrigues, is transferred to a new genus: Achaebana gen. n. Finally, cixiid endemism and their host-plant associations in the Mascarenes are discussed. (Resume d'auteur)

A remarkable new species of Acanthops Audinet-Serville, 1831, from French Guyana (Dictyoptera, Mantodea).

Revision of the neotropical genus Macromantis Saussure, 1871 (Dictyoptera, Mantidae). Two species were originally put in the genus Macromantis, and further a third was added ; but these species were badly definite, more or less greatly confused and at last synonymized. However they are really distinct, and even a fourth is present, described here as a new one. This paper, based on about one hundred specimens, states the question and gives the distinctive characters and the known distribution of each of these species., Deux espèces ont été placées à l'origine dans le genre Macromantis, puis une troisième y a été ajoutée ; mais ces espèces ont été mal définies, plus ou moins largement confondues et finalement mises en synonymie. Cependant elles sont bien distinctes et même il en existe une quatrième décrite ici comme nouvelle. Le présent article, basé sur une centaine de spécimens, fait le point sur la question en précisant les caractères distinctifs et la distribution connue de chacune de ces espèces., Roy Roger. Révision du genre néotropical Macromantis Saussure, 1871 (Dictyoptera, Mantidae). In: Bulletin de la Société entomologique de France, volume 107 (4), octobre 2002. pp. 403-418.

In this paper, we describe and illustrate a new species of parasitoid wasp as Brachymeria philornisae Delvare, sp. nov. The new species was reared from Philornis trinitensis Dodge & Aitken (Diptera: Muscidae) puparia that were found in the nests of the bird species Mimus gilvus (Vieillot) (Mimidae) and Tiaris bicolor (L.) (Thraupidae) in Tobago. The new species is of particular interest as it may be considered a potential biological control agent in locations where Philornis species are invasive, such as the Galapagos Islands. Closely related Brachymeria species had taxonomically ambiguous relationship in the past and are compared and reviewed. The species have been classified in the subgenus Pseudobrachymeria, but are here treated within the newly defined subconica species-group of Brachymeria as part of a sibling species complex designated as the subrugosa complex. Species assigned to the subconica species-group are listed and five, one unnamed, are assigned to the subrugosa complex and their females keyed. Species are separated by qualitative characters and morphometry using distance measurements. Trigonura annulipes Costa Lima is renamed as Brachymeria costalimai Delvare nom. nov. because of secondary homonymy.

The soft original material that was used to make the permanent slides of Tempere et Peragallo's 2nd edition of “Diatomees du Monde Entier” is available for study at the Laboratoire de Geologie of the Museum National d'Histoire Naturelle, Paris. This paper gives a list of the localities where the samples were taken and a list of the new taxa described from these samples.

This report describes Trocara virus, a newly recognized member of the genus Alphavirus, that has been isolated from Aedes serratus mosquitoes collected at two widely separated sites in the Amazon Basin. Biological, antigenic and genetic characteristics of the new virus are given. Results of these studies indicate that Trocara virus is the first member of a newly discovered antigenic complex within the family Togaviridae genus Alphavirus. The public health and veterinary importance of Trocara virus is still unknown.

Description d'une espèce nouvelle de phlébotome paléarctique : Phlebotomus (Transphlebotomus economidesi de Chypre. Le principal caractère d'identification étant la structure striée particulière des conduits, non dilatés, et des corps des spermathèques, l'holotype désigné est une femelle. Le mâle de la nouvelle espèce présente un nombre variable d'épines sur le style (4 à 6), mais la diagnose différentielle du mâle avec les espèces affines P. mascittii et P. canaaniticus reste délicate. Les aires de répartition des trois espèces du sous-genre Transphlebotomus sont rappelées.

Summary - Description of four new species and four populations of Rotylenchus (Nematoda: Hoplolaimidae). Proposal a tabular key - Four new species from France are described and figured: Rotylenchus ascalpi sp. n., characterised by an annulated, rounded and set off lip region; R. corsicus sp. n., characterised by a rounded, annulated lip region; R. echelimae sp. n., characterised by a truncated, smooth lip region; R. provincialis sp. n., characterised by a conoïd rounded, annulated lip region and an unannulated tail terminus.

SDS-PAGE of total bacterial proteins was applied to the classification of 25 Sudanese and five Kenyan strains isolated from the root nodules of #Acacia senegal$ and #Prosopis chilensis$. Twenty strains were also studied by multilocus enzyme electrophoresis (MLEE) and the whole 16S rRNA gene was sequenced from two strains representing the two major clusters. These results, together with the previuously reported numerical taxonomy analysis, pulsed-field gel electrophoresis studies, DNA-DNA dot-blot hybridisation, genomic fingerprinting using repetitive sequence-basec PCR, DNA base composition analysis, DNA-DNA reassociation analysis, partial sequencing of the 16S rRNA gene and RFLP analysis of the amplified 16S rRNA gene, showed that all 30 strains belong to the genus #Sinorhizobium$. Two of the strains grouped with #Sinorhizobium saheli$ and seven with #Sinorhizobium terangae$, while the rest did not cluster with any of the established species. The majority of the strains formed two phenotypically and genotypically distinct groups and we therefore propose that these strains should be classified as two new species, #Sinorhizobium arboris$ sp. nov. and #Sinorhizobium kostiense$ sp. nov.

This article is free to read on the publishers website A strictly anaerobic, spore-forming bacterium (3·0-5·0 × 0·4-0·8 μm), designated strain SR3T (T=type strain), which stained Gram-positive and possessed a Grampositive type cell wall was isolated from a methanogenic pilot-scale digester fed with olive mill wastewater (Sfax, Tunisia). It utilized a number of carbohydrates (glucose, fructose, sorbose, galactose, myo-inositol, sucrose, lactose, cellobiose), organic compounds (lactate, betaine, sarcosine, dimethylglycine, methanethiol, dimethylsulfide), alcohol (methanol) and all methoxylated aromatic compounds only in the presence of yeast extract (0·1%). The end products from carbohydrate fermentation were H2, CO2, formate, acetate and ethanol, that from lactate was methanol, those from methoxylated aromatics were acetate and butyrate, and that from betaine, sarcosine, dimethylglycine, methanethiol and dimethylsulfide was only acetate. Strain SR3T was non-motile, had a G+C content of 44 mol% and grew optimally at 37 °C and pH 7·4 on a glucose-containing medium. Phylogenetically, the closest relatives of strain SR3T were the non-methoxylated aromatic-degrading Clostridium xylanolyticum, Clostridium aerotolerans, Clostridium sphenoides and Clostridium celerecrescens (mean similarity of 98%). On the basis of the phenotypic, genotypic and phylogenetic characteristics of the isolate, it is proposed to designate strain SR3T as Clostridium methoxybenzovorans sp. nov. The type strain is SR3T (=DSM 12182T).

Very valuable papers concerning malacology of the Adriatic Sea deal, for the most part, with the systematics, whereas there is a substantial number of papers with very scarce information on the ecology of individual species. Since I intended to provide some more comprehensive data on individual species, rather complex bionomic and biocoenological research was undertaken aiming to study the taxonomy and the ecology of the Prosobranchiata group. Present research covered different biotopes of the northern, middle and southern Adriatic, both in the shallow coastal and deeper open littoral, and hard and mobile bottoms. Material was collected in two ways: 1) Scuba diving or direct collection and observations; and 2) an indirect method of collection of samples by Petersen grab, dredge and trawl. Throughout years of investigations of the coastal and open Adriatic, the species Cymatium corrugatum has been recorded only in the vicinity of the Vis and Hvar islands, at 60 and 80 m depths. It was found in the biocoenosis of detritic bottoms of the open sea and biocoenosis of coastal detritic bottoms. Cymatium corrugatum is a new species for the Adriatic and therefore it should be included in the register of the Gastropod fauna of the Adriatic Sea., Les travaux sur la malacologie de l'Adriatique concernent, en général, l'aspect taxonomique, tandis que ceux qui traitent de l'écologie des espèces individuelles, n'apportent que peu d'informations. Pour améliorer la connaissance des espèces individuelles, des recherches complexes ont été entreprises sur la bionomie et la biocoenologie du groupe des Prosobranches, parallèlement aux études taxonomiques et écologiques. Les recherches ont couvert différents biotopes de l'Adriatique septentrionale, centrale et méridionale, à la côte et au large, sur des fonds solides et mobiles. Deux méthodes de prélèvement ont été utilisées : 1) observation et échantillonnage directs par plongeurs en scaphandre autonome et 2) échantillonnage indirect par benne Petersen, dragage et chalutage. Au cours de plusieurs années, l'espèce Cymatium corrugatum n'a été signalée que près des îles Vis et Hvar, entre 60 et 80 m de profondeur, dans les biocoenoses des fonds détritiques côtiers et dans ceux du large. Cymatium corrugatum, espèce nouvelle pour l'Adriatique, devrait être insérée dans l'inventaire de la faune des gastéropodes adriatiques

A new species of Taeniocerus from the northern Myanmar, hitherto confused with T. bicuspis (Kaup, 1868) (Coleoptera, Passalidae). Taeniocerus mourzinei n. sp. is described, illustrated and compared with its sister-species T. bicuspis (Kaup, 1868), following confusion between the species caused by Arrow (1950). The chorology of the species is established : T. bicuspis at low altitudes from the south eastern side of the Himalayas (100-1300 m ; Sikkim, Bhutan, Assam) but absent from the Malay Peninsula, Thailand, Indochina, Sumatra and Borneo contrary to the opinion of certain authors ; T. mourzinei from similar low altitudes on the south eastern side of the Patkaï Mountains, on the India-Myanmar border. Both species are considered as vicariants., Taeniocerus mourzinei n. sp. (Aulacocyclinae) est décrit, illustré et comparé avec son espèce-sœur T. bicuspis (Kaup, 1868), les deux espèces ayant été confondues par Arrow (1950). Leur chorologie est établie : T. bicuspis, du versant sud-est de l'Himalaya oriental de basses altitudes (100-1300 m ; Sikkim, Bhoutan, Assam) mais absent de la péninsule Malaise, de Thaïlande, d'Indochine, de Sumatra et de Bornéo contrairement aux indications de plusieurs auteurs ; T. mourzinei, du versant sud-est de la chaîne du Patkaï, à la frontière entre l'Inde et le Myanmar (ex-Birmanie), aux mêmes altitudes.
