Adlafia diahotensis, sp. nov. (Bacillariophyceae), a new species from New Caledonia
Cryptogamie, Algologie 41 (1)
During a survey of epilithic diatoms in the running water of the main island of New Caledonia, a new species was found: Adlafia diahotensis Le Cohu, Marquié & Tudesque, sp. nov. This species is characterized by the valve outline with ends wedge shaped obtusely rounded. In light microscopy, the striae are only discernible in the center of the valve. In scanning electron microscopy, the internal proximal raphe endings are shortly deflected towards the primary side of the valve and far apart from each other.
Icacinaceae fossil fruits from three sites of the Paris Basin (early Eocene, France): local diversity and global biogeographic implications
Geodiversitas 42 (2)
The Icacinaceae family have an important fossil record, mainly in the Paleogene of North America and Europe. The importance of this family in the Paleogene of the Paris Basin has been investigated recently based on two assemblages, Le Quesnoy (Houdancourt) and Rivecourt (Oise), and here we treat the Icacinaceae from three additional early Eocene sites. The Passy site reveals the presence of a new species, Iodes passiciensis Del Rio & De Franceschi, sp. nov., unique in having 25-29 areoles with no freely ending ridgelets, small pores, and rounded ridges. Two other species described previously from the Paleocene of Rivecourt were also recorded.
An annotated list of hornwort and liverwort species of Serbia
Cryptogamie, Bryologie 41 (3)
The level of knowledge on the hornwort and liverwort flora of Serbia has increased in recent decades. Based on a thorough review of the literature and herbarium data, an updated list of the hepatic and liverwort taxa present in Serbia is compiled and presented. Taking into account recent taxonomic and nomenclatural changes, totals of 133 species and six infraspecific taxa are reported for the country. An additional eight species are rejected with explanatory annotations. The list includes data on the presence of taxa in separate regions and counties of the country.
A revision of Xylopia L. (Annonaceae): the species of Madagascar and the Mascarene islands
Adansonia 42 (1)
We recognize 30 species of the pantropical genus Xylopia L. from Madagascar and an additional three species from the Mascarene Islands. Of the six sections of the genus, three are represented in the region: sect. Xylopia, sect. Verdcourtia, and sect. Stenoxylopia. All species are endemic, and many are microendemics of conservation concern. The greatest species richness occurs in humid forests below 1000 m. Taxonomic review supports the hypothesis that the genus dispersed to Madagascar from continental Africa five times. Ten new species are described: Xylopia anomala D.M.Johnson & N.A.Murray, sp. nov., X. australis D.M.Johnson & N.A.Murray, sp. nov., X. carinata D.M.Johnson & N.A.Murray, sp.
On the taxonomic position of Phaenomenella Fraussen & Hadorn, 2006 (Neogastropoda, Buccinoidea) with description of two new species
Zoosystema 42 (3)
This contribution provides novel information on the anatomy, radula and phylogeny of several species of Phaenomenella Fraussen & Hadorn, 2006, a genus of Buccinoidea Rafinesque, 1815 with unclear affinities. Molecular phylogenetic analysis based on sequences of mitochondrial COI and nuclear 28S rRNA genes of different representatives of Buccinoidea revealed close relationships of Phaenomenella with Siphonalia A. Adams, 1863 both taxa forming a clade with maximal support. The anatomy of two species of the latter genus was examined for the first time for comparative purposes.
Functional inferences on the long bones of Ischyrictis zibethoides (Blainville, 1841) (Carnivora, Mustelidae) from the middle Miocene locality of Sansan (Gers, France)
Geodiversitas 42 (1)
In the present paper, we carry out a deep analysis of the functional anatomy of the long bones of the fossil, wolverine-sized mustelid Ischyrictis zibethoides (Blainville, 1841) in comparison with that of several extant related species. The study reveals that this animal lacked specific adaptations for either climbing or running, probably being a terrestrial predator that foraged mostly on the ground. Thus, some features of the anatomy of its long bones suggests that I. zibethoides required a strong control of those articulations involved in terrestrial locomotion, such as the elbow or the coxofemoral joint.
A taxonomic revision of Aneuraceae (Marchantiophyta) from eastern Africa with an interactive identification key
Cryptogamie, Bryologie 41 (2)
A taxonomic revision of the liverwort family Aneuraceae in eastern Africa is presented based on the results of an integrative approach. Molecular and morphological data lead to the recognition of fourteen species in eastern Africa, in three genera: eleven species in Riccardia Gray, two in Aneura Dumort. and one in Afroriccardia Reeb & Gradst. One further species, R. multifida, may be expected in eastern Africa and is included in this treatment. Keys, descriptions and illustrations are provided for the accepted species together with data on types, synonymy, geographical distribution, habitat and differentiating characters. A knowledge database was built using Xper3 and an interactive key was generated using the Xper3 platform tools.
The high complexity of Micronetinae Hull, 1920 (Araneae, Linyphiidae) evidenced through ten new cave-dweller species from the Morocco
Zoosystema 42 (1)
The Museum of Natural Sciences of Barcelona is the repository of a set of samples of spiders captured during a prolonged period of time in various caves of the Moroccan Atlas.
Priorités de conservation des espèces en Auvergne : l’apport des Listes rouges régionales
Naturae 2020 (1)
Using subnational Red Lists from the former Auvergne region and available occurrence data, multi-group cross-analyses were carried out to provide a synthesis of the conservation status of species of Auvergne and to illustrate the main trends as well as the main issues for local biodiversity. The results show there are a large number of threatened and near threatened species, including more than half of amphibians, bryophytes and birds. The highest proportions of unknown species concern certain vertebrates (amphibians and mammals) and flora. There is a lack of public policy framework or regulatory statutes for more than 170 species listed under the ‘Data Deficient’ category and for as many endangered species.
New Pottiaceae genera to the moss flora of Saudi Arabia and the Arabian Peninsula
Cryptogamie, Bryologie 41 (1)
Hyophila Brid., Leptophascum (Müll.Hal.) J.Guerra & M.J.Cano and Plaubelia Brid. are new genera to the bryoflora of Saudi Arabia while the last two genera are new to the Arabian Peninsula. All these genera are represented by one species each namely; Hyophila baginsensis Müll.Hal., Leptophascum leptophyllum (Müll.Hal.) J.Guerra & M.J.Cano and Plaubelia involuta (Magill) R.H.Zander. Hyophila baginsensis is a new record to the bryoflora of Asia continent. The new recorded species are described and illustrated. Their sites, habitats, distribution, elements and some floristic remarks are given.
The exploitation of molluscs and other invertebrates in Alexandria (Egypt) from the Hellenistic period to Late Antiquity: food, usage, and trade
Anthropozoologica 55 (1)
A number of archaeological salvage excavations conducted in Alexandria (Lower Egypt) by the Centre d’Études alexandrines have provided a corpus of around 2000 fragments of marine, freshwater and terrestrial invertebrates. These archeomalacological remains come from several occupation layers of the same district within the town, the Brucheion, dating from the end of the 4th century BC until the 6th century AD. After macroscopic observations and through a binocular microscope, the analysis of the malacofauna vestiges has provided previously unknown information regarding the exploitation of the aquatic environment by Alexandrians during antiquity. In addition, some residues of mineral material preserved on the shells have been analysed under a scanning electron microscope (SEM).
New remains of kollpaniine “condylarths” (Panameriungulata) from the early Palaeocene of Bolivia shed light on hypocone origins and molar proportions among ungulate-like placentals
Geodiversitas 41 (25)
The description of new specimens of kollpaniines “condylarths” from Tiupampa (early Palaeocene of Bolivia) represents a significant addition to the knowledge of the earliest fauna of South American ungulates. Several partial mandibles and maxillae of Molinodus suarezi and Simoclaenus sylvaticus are described. The morphology of the lower premolars of Molinodus, being associated to lower molars, is established and a previous referral of an isolated p4 is rejected. A maxilla of Simoclaenus reveals the morphology of the so far unknown P1-4 of this taxon and allows a discussion on the development of the protocone in Palaeocene “condylarths”.
