Régime alimentaire du Lézard ocellé <i>Timon lepidus </i>(Daudin, 1802) sur les rives de l’Estéron et du Var (Alpes-Maritimes, France)
No full textL’étude repose sur l’analyse de 160 fèces de Lézard ocellé Timon lepidus (Daudin, 1802) collectées de 2017 à 2020 à raison d’une visite par semaine entre mars et novembre depuis la piste cyclable bordant l’Estéron et le Var (Alpes-Maritimes, France). Les 2234 macrorestes trouvés se répartissent en 32 % d’origine végétale et 68 % d’origine animale, et parmi ces derniers 63 % d’insectes, 3 % de myriapodes, 1,4 % d’arachnides et 1,0 % de mollusques. Une part de fruits non négligeable (2949 graines et 87 noyaux) apparait dans le régime alimentaire. Les écarts extrêmes en taille et masse de certaines proies invitent à comparer les résultats obtenus en nombre et pourcentage avec leur équivalent en biomasse. Cela montre que les Orthoptères, dont une part importante de Decticus albifrons (Fabricius, 1775) fournissent à eux seuls 35 % de la biomasse totale. Quant au végétal, la part fournie par la Corroyère à feuilles de Myrte (Coriaria myrtifolia L.) représente 17 % de la biomasse totale consommée. Les particularités du régime sont discutées et comparées aux résultats obtenus dans la plaine de la Crau et sur l’île d’Oléron.The study is based on the analysis of 160 faeces of Ocellated Lizard Timon lepidus (Daudin, 1802) collected from 2017 to 2020 on the basis of one visit per week between March and November from the cycle path bordering Estéron and Var (Alpes-Maritimes, France). The 2234 macroremains found are divided into 32% of plant origin and 68% of animal origin, i.e. 63% insects, 3% myriapods, 1.4% arachnids and 1.0% molluscs. A significant proportion of fruits (2949 seeds and 87 stones) appears in the diet. The extreme differences in size and mass of certain prey invite us to compare the results obtained in number and percentage with their equivalent in biomass. This shows that the Orthoptera, including a large part of Decticus albifrons (Fabricius, 1775) alone provide 35% of the total biomass. As for the plant, the share provided by the myrtle-leaved Corroyère (Coriaria myrtifolia L.) represents 17% of the total biomass consumed. The particularities of the diet are discussed and compared with the results obtained in the Crau plain and on the island of Oléron.</p
Revision of the <i>Traumatomutilla quadrinotata</i> species-group (Hymenoptera: Mutillidae, Sphaeropthalminae): new synonyms, sex associations, and a new species from the Brazilian Atlantic Forest
No full textThe Traumatomutilla quadrinotata species-group is reviewed, leaving it with six species known from both sexes, four known from females only and two known from males only. The following junior synonyms are proposed: Traumatomutilla austera (Gerstaecker, 1874) [= Mutilla sigillata Gerstaecker, 1874 syn. nov.]; T. chrysozona (Gerstaecker, 1874) [= Mutilla lugubrina Dalla Torre, 1897 syn. nov.; = Ephuta dives André, 1906 syn. nov.]; T. quadripustulata (Klug, 1821) [= M. pruinosa Smith, 1855 syn. nov.; = M. maraca Cresson, 1902 syn. nov.]; T. sancta (Gerstaecker, 1874) [= M. solemnis Cresson, 1902 syn. nov.]; T. incerta (Spinola, 1841) [= M. dentata Smith, 1879 syn. nov.; =M. sodalicia Kohl, 1882 syn. nov.; = T. tabatinga Casal, 1969 syn. nov.; = T. dignitosa Mickel, 1952 syn. nov.]; T. pompiliformis (Gerstaekcer, 1874) [= M. serra Cresson, 1902 syn. nov.]; T. infernalis (Gerstaecker, 1874) [= M. floccosa Gerstaecker, 1874 syn. nov.]. The hitherto undescribed males of T. ameliae Casal, 1969 and T. quadrinotata (Klug, 1821), are fully described and illustrated. A new species, T. tetratrauma Bartholomay & Williams sp. nov., is described based on couples from the Brazilian Atlantic Forest. All previously described species are redescribed and illustrated. Identification keys for males, females, and known color forms are also provided.</p
A new species and a new record of Cirratulidae (Annelida, Cirratulida) from Loki’s Castle vent field
No full textDeep-sea research is a very active field in which environments such as hydrothermal vents are of particular interest because they host a unique and often endemic fauna. In this paper, we describe a new species of the genus Caulleriella Chamberlin, 1919 (Annelida, Cirratulidae Ryckholt, 1851) and report the presence of Raricirrus arcticus Buzhinskaja & Smirnov, 2017 at Loki’s Castle vent field (LCVF), which is the first detailed report of this species since the original description. Both species are illustrated and similarities with closely related species are discussed. We provide genetic data for COI, 16S and 28S for both species. Phylogenetic analyses confirm the identity of each species and the monophyly of each genus. Caulleriella jormungandri sp. nov., in addition to being common at LCVF, is recorded from stations without any known chemosynthesis-based environments, suggesting this species to be a part of the background fauna. Raricirrus arcticus was originally described from a cold seep, and with the new records from the Loki’s Castle hydrothermal vent, it is considered to be a specialist of chemosynthesis-based ecosystems and the geographic distribution of the species is vastly expanded from the Laptev Sea to the Nordic Seas.</p
An integrative systematic revision of the wishbone spiders (Araneae: Anamidae: <i>Aname</i> L. Koch, 1873) of subtropical and tropical eastern Australia, with the description of 55 new species
No full textSpiders of the genus Aname L. Koch, 1873, commonly referred to as wishbone spiders, are a ubiquitous and extremely diverse component of the Australian mygalomorph fauna. Distributed across most of mainland Australia, and with an estimated endemic fauna in excess of 300 species, it is perhaps the world’s most diverse mygalomorph spider genus. Unsurprisingly, this group presents an enormous taxonomic challenge, with 80% or more of the fauna still undescribed, and a large proportion of species occurring in arid, semi-arid or otherwise remote parts of inland Australia. To address these shortfalls, this study represents the first in a planned series of major revisions to rapidly advance our knowledge of the Australian wishbone spiders. Here, we revise the Aname fauna of subtropical and tropical eastern Australia, applying an integrative approach of unprecedented monographic scope for a taxonomic study on Australian Mygalomorphae, bringing together morphological monography, live habitus information, burrowing biology and molecular phylogenetics resulting from extensive field work. Our expanded molecular phylogeny is augmented with 131 new barcode (COI) sequences from eastern Australian Aname species, and we provide descriptions, natural history observations and distributional data for a total of 68 eastern species. Of these, 10 represent redescriptions of previously described and valid species: A. barrema Raven, 1985, A. blackdownensis Raven, 1985, A. camara Raven, 1985, A. carina Raven, 1985, A. distincta (Rainbow, 1914), A. longitheca Raven, 1985, A. inimica Raven, 1985, A. pallida L. Koch, 1873, A. robertsorum Raven, 1985, and A. warialda Raven, 1985. Three represent species previously considered junior synonyms that have now been revalidated: A. attenuata (Rainbow & Pulleine, 1918) stat. rev., A. giraulti (Rainbow, 1914) stat. rev., and A. villosa Rainbow & Pulleine, 1918 stat. rev. One species (Aname collinsorum Raven, 1985) is now considered a junior synonym of Aname giraulti (Rainbow, 1914) syn. nov. Finally, 55 species are newly described: Aname albicula sp. nov., A. ammolithica sp. nov., A. aurantella sp. nov., A. aurensis sp. nov., A. barakula sp. nov., A. bifaceta sp. nov., A. boreovillosa sp. nov., A. braemar sp. nov., A. briggsi sp. nov., A. broadwater sp. nov., A. calida sp. nov., A. callitra sp. nov., A. cassowariensis sp. nov., A. consuelo sp. nov., A. convoluta sp. nov., A. corundaria sp. nov., A. cudmore sp. nov., A. dingo sp. nov., A. distorta sp. nov., A. eddieorum sp. nov., A. ethabuka sp. nov., A. ferruginea sp. nov., A. flexicaudula sp. nov., A. fossoria sp. nov., A. fuscochelicera sp. nov., A. gilbertensis sp. nov., A. harmoniosa sp. nov., A. hughenden sp. nov., A. inglewood sp. nov., A. insolita sp. nov., A. intermedia sp. nov., A. lambkinae sp. nov., A. lawrenceae sp. nov., A. litoralis sp. nov., A. magnifica sp. nov., A. mariala sp. nov., A. mulgana sp. nov., A. namoi sp. nov., A. nigrochelicera sp. nov., A. nigrotarsa sp. nov., A. occivillosa sp. nov., A. olkola sp. nov., A. platensis sp. nov., A. pyroensis sp. nov., A. rubrochelicera sp. nov., A. rupicola sp. nov., A. savannella sp. nov., A. savannensis sp. nov., A. scutitheca sp. nov., A. serpentina sp. nov., A. tropicana sp. nov., A. truncata sp. nov., A. vigilata sp. nov., A. viridiensis sp. nov., and A. warrego sp. nov.</p
Updating the taxonomy of polymorphic plant taxa: six Atlantic Forest species segregated from the widely circumscribed <i>Oxalis polymorpha</i> Mart. ex Zucc. (Oxalidales, Oxalidaceae)
No full textWidely circumscribed taxa are good candidates for in-depth taxonomic studies. The current taxonomy of Oxalis sect. Polymorphae includes 13 species mostly endemic to the Brazilian Atlantic Forest, in eastern Brazil. Oxalis polymorpha Mart. ex Zucc., the type-species of the section, exhibits a wide morphological variability and includes at least four recognized morphotypes. We propose the segregation of six species from this widely circumscribed O. polymorpha by combining morphological and molecular systematic data from the nuclear and plastid genomes. Thus, Oxalis decipiens Progel, previously treated under O. polymorpha, is accepted as a distinct species. The same is valid for O. polymorpha subsp. tijucana Lourteig, which is recognised at species level (O. tijucana (Lourteig) Fiaschi). Four additional new species are described based on material that were formerly placed under the wide circumscription of O. polymorpha: O. amorimii Fiaschi sp. nov., O. animarum Fiaschi sp. nov., O. idimae Fiaschi sp. nov., and O. itatingae Fiaschi sp. nov. We provide evidence that one of these species, O. itatingae, is phylogenetically closer to O. sect. Holophyllum than to other species of O. sect. Polymorphae, while the other species, excluding O. tijucana, emerged as non-sister taxa within the latter. Descriptions, illustrations, geographic distribution maps, preliminary conservation assessments, taxonomic notes, and an identification key to species of Oxalis sect. Polymorphae are provided.</p
La chasse aux « sauriens » jurassiques dans le nord-est de la France aux xviiie et xixe siècles (Lorraine, Champagne-Ardenne et Alsace)
No full textCet article retrace l’histoire des premières découvertes de reptiles dans le Jurassique du nord-est de la France au xviiie siècle et au xixe siècle. Pour chacun des départements concernés (Ardennes, Aube, Marne, Haute-Marne, Meurthe-et-Moselle, Meuse, Moselle, Bas-Rhin et Vosges), les personnalités qui ont contribué à ces découvertes sont présentées chronologiquement. Un inventaire des spécimens conservés dans plusieurs collections muséales et universitaires françaises est proposé. Il permet de mettre en évidence un riche registre fossile de reptiles qui s’échelonne de l’Hettangien au Tithonien et qui est représenté par des Ichthyosauria, des Plesiosauria, des Thalattosuchia et des Dinosauria. Les formations ayant livré des restes de reptiles en plus grande abondance comprennent le Grès d’Hettange (Hettangien), le Calcaire à gryphées (Hettangien-Sinémurien inférieur), les Schistes cartons et la Marne de Flize (Toarcien inférieur), les Argiles de la Woëvre (Callovien-Oxfordien inférieur), les Marnes à exogyres ou Marnes et calcaires à Nanogyra virgula (Kimméridgien supérieur) et les calcaires du Tithonien inférieur. Cet inventaire révèle également une riche faune provenant de la Formation ferrifère ou Minette à la transition entre le Jurassique inférieur et moyen (Toarcien supérieur-Aalénien), conséquence de l’exploitation intensive au xixe siècle du minerai de fer en Lorraine. Viennent s’ajouter à cette liste principale, des spécimens épars provenant du Pliensbachien, du Bajocien et du Bathonien. Des documents manuscrits et iconographiques inédits permettent de préciser le contexte historique de découvertes de spécimens importants, aujourd’hui perdus ou détruits, comme l’holotype de Mosellaesaurus rostrominor Monard, 1846, l’holotype de Machimosaurus mosae Liénard in Sauvage & Liénard, 1879 (Thalattosuchia), et ce que pourrait être un des premiers ichthyosaures trouvés en France au xviiie siècle par le père Nicolas Le Bonnetier (1720-1804). Ces documents ont permis en outre de redécouvrir des spécimens qui avaient été portés à la connaissance de Georges Cuvier mais dont l’importance historique était oubliée depuis longtemps.This article traces the history of the first discoveries of reptiles in the Jurassic of northeastern France in the 18th and 19th centuries. For each of the concerned departments (Ardennes, Aube, Marne, Haute-Marne, Meurthe-et-Moselle, Meuse, Moselle, Bas-Rhin and Vosges), the personalities who contributed to these discoveries are presented chronologically. An inventory of specimens preserved in several French museum and university collections is proposed. It highlights a rich fossil reptile record which spans from the Hettangian to the Tithonian and which is represented by Ichthyosauria, Plesiosauria, Thalattosuchia and Dinosauria. The formations having yielded the most abundant reptilian remains include the “Grès d’Hettange” (Hettangian), the “Calcaire à gryphées” (Hettangian to lower Sinemurian), the “Schistes cartons” and the “Marne de Flize” (lower Toarcian), the “Argiles de la Woëvre” (Callovian to lower Oxfordian), the “Marnes à exogyres” or “Marnes et calcaires à Nanogyra virgula” (upper Kimmeridgian) and the lower Tithonian limestones. This inventory also reveals a rich reptilian fossil record coming from the “Formation ferrifère” or “Minette” at the Early-Middle Jurassic transition (upper Toarcian-Aalenian), consequence of the intensive exploitation of iron ore in Lorraine during the 19th century. Scattered specimens from the Pliensbachian, Bajocian and Bathonian complete this main list. Unpublished manuscript and iconographic documents make it possible to clarify the historical context of the discoveries of important specimens, now lost or destroyed, such as the holotype of Mosellaesaurus rostrominor Monard, 1846, the holotype of Machimosaurus mosae Liénard in Sauvage & Liénard, 1879 (Thalattosuchia), and what could be one of the first ichthyosaurs found in France in the 18th century by Father Nicolas Le Bonnetier (1720-1804). These documents also made it possible to rediscover specimens which had been brought to the attention of Georges Cuvier but whose historical importance had long been forgotten.</p
<i>Gryllofulvius gibbosus</i> Taszakowski gen. et sp. nov. – a remarkable, flightless and stridulating plant bug (Heteroptera: Miridae: Cylapinae) from Madagascar
No full textGryllofulvius Taszakowski gen. nov., a new remarkable genus of the subfamily Cylapinae, tribe Fulviini, is described from Madagascar. The new species Gryllofulvius gibbosus Taszakowski gen. et sp. nov. is documented with photographic images, SEM micrographs of the selected body parts, and female genitalic structures. The stridulatory device (embolial stridulitrum and metafemoral plectra) of the new taxon is described, and the stridulation in Cylapinae is discussed.</p
A new species of <i>Acanthosaura</i> Gray, 1831 (Reptilia: Agamidae) from the Truong Son Mountain Range, Vietnam
No full textWe describe a new species of the genus Acanthosaura Gray, 1831 from the Truong Son Mountain Range, southern Vietnam, based on integrative taxonomic analyses. Acanthosaura cuongi sp. nov. differs from its congeners by a combination of the following diagnostic characteristics: size moderate (snout-vent length: 79.4–104.61 mm); the absence of a diastema between the short nuchal and dorsal crest spines; vertebral crests composed of two rows of enlarged, keeled, pointed scales, arranged in a zipper line; various body coloration with light-green, orange-yellow, and light or purple-gray; black eye patch extending posteriorly to the anterior edge of tympanum. Maximum likelihood (ML) and Bayesian inference (BI) analyses using two mitochondrial genes (COI and Cytb) support the monophyly of Acanthosaura cuongi. Furthermore, the new species differs from the closest lineage consisting of A. coronata Günther, 1861 by having pairwise genetic distances of 11.58–12.11%, and have a maximal intraspecific distance of 0.35%. This is the 21st species of Acanthosaura and the tenth species of the genus reported from Vietnam.</p
