Cicadetta sibillae Hertach & Trilar, 2015, nouvelle espèce de cigale pour la France (Hemiptera, Cicadidae) et premières analyses des sons complexes émis durant la cymbalisation d’appel nuptial
Zoosystema 40 (8)
The Cicadetta (Scopoli, 1772) species complex contains six cicada species from France including Corsica. Some prospecting carried out at the end of June 2016 in the Tende area (Alpes-Maritimes department) revealed the presence of a seventh species in this complex: C. sibill Hertach & Trilar, 2015, a cicada newly described from Italy and Switzerland (Hertach et al. 20 2015). Its ecology is discussed and a first distribution map is drawn up. Morphologically very close to C. cerdan Puissant & Boulard, 2000, the study of the genitalia of C. sibill shows some new morphological characters notably in the shape of the pseudoparameres.
Géographie du hareng à la fin du Moyen Âge : les mers du Nord, des lieux de production ?
Anthropozoologica 53 (6)
Wider herring fishing appeared in the Northern seas in the late Middle Ages. It became a godsend for urban markets, which needed plentiful and cheap food. Herring was a mass product in Northern Europe at that time and supplied mainly towns. That situation supposed to master new fishing and sailing techniques needed for such food supplies. Herring fishing was a novelty for it was not organised locally anymore. Fishing sites may be compared to series of hubs that assembled together different processes that followed the migration of fish. The sea itself thus became a kind of hinterland for urban markets. Then, when herrings were unloaded, public authorities took many measures (against fraud or too plentiful catches) that show the social significance of this fish.
Structural, functional, and physiological signals in ichthyosaur vertebral centrum microanatomy and histology
Geodiversitas 40 (7)
The first tuna-shaped amniotes evolved among ichthyosaurs, but this group exhibits in fact a wide diversity of morphologies and swimming modes. The histology and microanatomical features of vertebral centra of a diversity of ichthyosaur taxa from most basal to highly derived illustrating this variability were analyzed. The occurrence of unusual parallel fibered bone with platings of true parallel-fibered bone confirms high growth rate in all these taxa. Ichthyosaur vertebrae, which are deeply amphicoelous, show a limited endosteal territory associated with a limited growth in length. No bone mass increase nor decrease occurs. The vertebral centrum is spongious, and two microtypes are observed in the periosteal territory, with different degrees of organization of the trabecular network.
Hanging on – lucinid bivalve survivors from the Paleocene and Eocene in the western Indian Ocean (Bivalvia: Lucinidae)
Zoosystema 40 (7)
Rare species of three long-lived lucinid genera, Gibbolucina Cossmann, 1904, Barbierella Chavan, 1938 and Retrolucina n. gen., with origins in the Paleocene and Eocene of western Tethys, are present in the Mozambique Channel area of the southwestern Indian Ocean but absent elsewhere in the Indo-West Pacific. A new species, Gibbolucina zelee n. sp., is described from the Banc de la Zélée and western Madagascar that resembles Miocene species from western France. Since their origin in the Paleocene to the present day Barbierella species have always been rare.
Floral reversion and first record of pseudovivipary in some species of Poaceae
Adansonia 40 (5)
This contribution constitutes the first report of floral reversion and occurrence of pseudovivipary in Paspalum ceresia (Kuntze) Chase, P. stellatum Humb. & Bonpl. ex Flüggé and Thysanolaena latifolia (Roxb. ex Hornem.) Honda. Observations were made in material kept under cultivation in Buenos Aires (Argentina) since March 2001. Proliferating spikelets are described and illustrated, and some implications in the origin of spikelet organs are discussed. An up to date table including the genera of Poaceae where this phenomenon has been documented is also provided.
L’occurrence du Lézard ocellé Timon lepidus (Daudin, 1802) (Sauria, Lacertidae) en altitude est-elle sporadique ? Le cas du sud-est des Alpes françaises
Naturae 2018 (1)
Species distribution knowledge is a major issue for conservation, especially in times drive by global changes. However, common assumptions and non-standardized distribution of sample or data set often result in distorted representation because they do not take into account species detection probability. The natural range of the Ocellated lizard Timon lepidus (Daudin, 1802) (Lacertidae) seems well described in the literature and is known to occur very sporadically in habitats above 600-700 m elevation. However, both historic regional data retrieval (Silene-PACA regional database) and recent data collected in higher elevated sites of the south-eastern French Alps (Hautes-Alpes, Alpes-de-Haute-Provence and Alpes-Maritimes) drive to different conclusion.
Neogene and Quaternary fossil remains of beaked whales (Cetacea, Odontoceti, Ziphiidae) from deep-sea deposits off Crozet and Kerguelen islands, Southern Ocean
Geodiversitas 40 (6)
Although a high number of extant beaked whale species (Cetacea, Odontoceti, Ziphiidae) live in the Southern Ocean and neighbouring areas, only little is known about the past occupation of the region by these highly specialized, deep diving and echolocating cetaceans. Recently, longline fishing activities along the seafloor at depths of 500-2000 m off the sub-antarctic Crozet and Kerguelen islands, Indian sector of Southern Ocean, resulted in the accessory “capture” of tens of ziphiid fossil cranial remains. Our description and comparison of the best-preserved and most diagnostic crania from this sample lead to the identification of more than eight species in at least seven genera: the hyperoodontines Africanacetus ceratopsis, Khoikhoicetus kergueleni n.
Camelus thomasi Pomel, 1893 from the Pleistocene type-locality Tighennif (Algeria). Comparisons with modern Camelus
Geodiversitas 40 (5)
We describe here the whole collection of Camelus thomasi Pomel, 1893 from the Pleistocene type-locality Tighennif (Ternifine) in Algeria. Detailed morphological and metric comparisons with the two species of modern Camelus Linnaeus, 1758, C. bactrianus Linnaeus, 1758 and C. dromedarius Linnaeus, 1758, show that it is clearly distinct from both of them. It is mainly characterized by pachyostosis especially marked in the mandible, a size slightly greater than modern forms, broad molars with strong styles, and several unique cranial features. The species seems restricted to the terminal Early Pleistocene and is not definitely known outside Northwestern Africa.
A review of the brachyuran deep-sea vent community of the western Pacific, with two new species of Austinograea Hessler & Martin, 1989 (Crustacea, Decapoda, Brachyura, Bythograeidae) from the Lau and North Fiji Back-Arc Basins
Zoosystema 40 (5)
Two new species of the genus Austinograea Hessler & Martin, 1989 (Bythograeidae Williams, 1980), distinct from A. williamsi Hessler & Martin, 1989 and A. alayseae Guinot, 1990, are here reported from hydrothermal vent fields of the southwestern Pacific: A. hourdezi n. sp. and A. jolliveti n. sp., both in the Lau and North Fiji Back-Arc Basins. Austinograea hourdezi n. sp. is characterised by two depressions appearing as dark spots on the palm of both chelipeds in males and differs from the more northern A. williamsi and the Indian A. rodriguezensis Tsuchida & Hashimoto, 2002, which show only one spot on the male chelae, near the base of the dactylus.
Animaux et monstres marins dans la plus ancienne chronique polonaise
Anthropozoologica 53 (4)
The present article is dedicated to the analysis of the representation of marine animals and marine monsters in the oldest Polish chronicle, namely the Chronica et Gesta ducum sive principum Polonorum, written between 1112 and 1116 by an anonymous author traditionnaly refered to as the Gallus anonymus. Marine animals and marines monsters occupy a modest place in this work since they appear mainly in two fragments, that is to say in the song allegedly sang by the Polish soldiers after the conquest of the Pomeranian town of Kołobrzeg, and in one sentence in which the anonymous writer compares the Czech soldiers to marine monsters.
The world fauna of Synchroidae Lacordaire, 1859 (Coleoptera, Tenebrionoidea, Synchroidae)
European Journal of Taxonomy 2018 (407)
Synchroidae Lacordaire, 1859 is a taxonomically and biologically poorly known group. In the present paper, diagnostic characters used to separate genera are analysed and the phylogenetic relationships within this family are preliminarily investigated. Results suggest that the characteristic Synchroa pangu Hsiao, Li, Liu & Pang, 2016 can be removed to establish a new genus, Thescelosynchroa gen. nov. The new combination, T. pangu (Hsiao, Li, Liu & Pang) gen. et comb. nov., is proposed. The definitions of Synchroa Newman, 1838 and Synchroina Fairmaire, 1898 are revised. Moreover, morphological analysis and character comparison also suggest that the familial placement of Mallodrya subaenea Horn, 1888 is questionable.
