Mallomonas vietnamica Gusev, Kezlya & Tran, sp. nov. (Synurales, Chrysophyceae), a new species, that shares some features with fossil taxa
Cryptogamie, Algologie 42 (3)
A new species, Mallomonas vietnamica Gusev, Kezlya & Tran, sp. nov., is described from Vietnam based on silica-scale morphology elucidated by transmission and scanning electron microscopies. The species belongs in section Mallomonas Perty and is characterized by large oval scales with a wide and deep dome, which is recessed from the scale perimeter. The domes are shifted to the right side of scales and oriented at different angles to the scale’s longitudinal axis. Bristles of the newly described taxon are characterized by a distinctly hooked foot. Scales of M. vietnamica Gusev, Kezlya & Tran, sp. nov. were found at only one locality in Hanoi, at the border of Ba Vi National Park in the freshwater Da River (Sông Đà).
The leaf-miner flies (Diptera: Agromyzidae) of Mitaraka, French Guiana
Zoosystema 43 (6)Preliminary data on the agromyzid fauna (Diptera: Agromyzidae) collected during the “Our Planet Reviewed” expedition in Mitaraka (French Guiana) is provided. A total of 138 specimens representing 10 genera and 50 morphospecies are recorded. Melanagromyza Hendel, 1920 and Ophiomyia Braschnikov, 1897 were the most diverse genera with 15 and 14 species respectively, followed by Phytobia Lioy, 1864 (five species), Japanagromyza Sasakawa, 1958 and Calycomyza Hendel, 1931 (four species each), Liriomyza Mik, 1894 (three species), Nemorimyza Frey, 1946 (two species), and Agromyza Fallén, 1810, Cerodontha Rondani, 1861, and Phytoliriomyza Hendel, 1931 (one species each).
Taphonomy of a Panopea Ménard de la Groye, 1807 shell bed from the Pisco Formation (Miocene, Peru)
Comptes Rendus Palevol 20 (8)
Invertebrate taphonomy can provide significant information about the post-mortem processes that affected the fossil record. In the East Pisco Basin of southern Peru, a Panopea Ménard de la Groye, 1807 shell bed was found in the upper Miocene strata of the Pisco Formation, hinting at a peculiar biostratinomic and diagenetic history. This bed contains abundant invertebrate fossil molds cemented by dolomite. The specimens of the deep infaunal bivalve, Panopea sp., occur together with bivalves representative of shallow infaunal species (Trachycardium sp. and Dosinia ponderosa [Gray, 1838]) and balanid barnacles, which are sessile encrusters.
The taxonomic position and lectotypification of Frullania diversitexta Steph. (Frullaniaceae, Marchantiophyta) and its synonyms, with notes on the placement of F. ignatovii Sofronova, Mamontov & Potemkin
Cryptogamie, Bryologie 42 (3)
Frullania diversitexta Steph. currently occupies its own subgenus, subg. Diversitextae (Kamim.) S.Hatt., although its taxonomic placement is somewhat enigmatic. The habit of the species, as well as the position and shape of the lobules, are morphologically comparable to species in subg. Diastaloba Spruce and subg. Frullania Spruce, whereas its tuberculate perianth ornamentation is reminiscent of species in subg. Trachycolea Spruce. Here, molecular sequence data resolves F. diversitexta within subg. Trachycolea in a relationship with F. plana Sull. (sect. Planae R.M.Schust.). Frullania diversitexta and F.
Détection précoce et lutte rapide contre la plante aquatique exotique Hydrilla verticillata (L.f.) Royle en Martinique
Naturae 2021 (5)
The problem of invasive alien species is increasingly being taken into consideration in Martinique, which seemed to have a certain resilience compared to other French tropical island territories. In this way, like nearly 70 alien and potentially invasive plant species, populations of Verticillate hydrilla (Hydrilla verticillata (L.f.) Royle) are monitored using mapping tools by the National Forestry Office, the Government Agency in charge of Environment and the Botanical Conservatory of Martinique. Following new distribution data reported by the existing monitoring network, a control campaign was conducted in 2016.
Two new genera and two new species of troglobitic harvestmen of Stygnopsidae (Opiliones, Laniatores, Gonyleptoidea) from Oaxaca, Mexico, with notes on selected morphological characters
Zoosystema 43 (5)Two monotypic and troglobitic genera of harvestmen are described from caves in Oaxaca, Mexico: The Karosinae Cruz-López & Francke, 2017 Brujita chapulapa n. gen., n. sp. and the Stygnopsinae Sørensen, 1932 Toojah cimutaa n. gen., n. sp., both based on males only. Also, based on the examination of the male holotype of Hoplobunus planus Goodnight & Goodnight, 1973, the new combination is proposed: Mictlana plana (Goodnight & Goodnight, 1973) n. comb., proposing an emended diagnosis for Mictlana Cruz-López & Francke, 2015, including an analysis of the dilemma of the position of the ocularium and observations on selected homoplastic characters.
Stratigraphy, age, and vertebrate palaeontology of the latest Cretaceous Quintanilla la Ojada locality (Basque-Cantabrian Region, northern Spain): a synthesis
Comptes Rendus Palevol 20 (7)
The Quintanilla la Ojada section (Basque-Cantabrian Region, northern Spain) has yielded two assemblages of Late Cretaceous vertebrates, deposited during the Maastrichtian in coastal environments and related to a transgressive lag at the base of the Valdenoceda Formation. Numerous teeth of Elasmobranchii and Actinopterygii are the most prevailing fossil material, although scarce teeth of marine reptiles (Mosasauridae) and dinosaurs (Hadrosauridae) also occur. The presence of one hadrosaurian tooth, a terrestrial taxon, constitutes the first report of ornithischians in the Valdenoceda Formation.
Crystallodon Alvarenga gen. nov., a new genus of the Auriculariales from the Neotropics
Cryptogamie, Mycologie 42 (2)
Heterochaete subgelatinosa Bodman (Auriculariales, Basidiomycota) was first described from material collected in Panama and was hitherto exclusively known from the type locality. We recently re-collected specimens of this species in the Atlantic forest of North-eastern Brazil. Morphological and molecular data suggest that H. subgelatinosa is not closely related to other species of Heterochaete Pat. studied with modern methods. Therefore, we here propose the establishment of a new monotypic genus, Crystallodon Alvarenga gen. nov., characterized by the presence of hyphal pegs surrounded by crystals.
The hooting past. Re-evaluating the role of owls in shaping human-place relations throughout the Pleistocene
Anthropozoologica 56 (3)
Previous research concerned with the significance of animals in early human evolution has overwhelmingly focussed on large mammals – especially the iconic suite of herbivores and carnivores once inhabiting the Eurasian Mammoth steppes. Building on earlier work of the author, this paper addresses the underrated importance of owls for human life throughout the Pleistocene – predatory birds which only occasionally feature in Palaeolithic visual culture and have hitherto attracted scholarly attention mainly as taphonomic agents. We argue that Pleistocene strigiformes had a crucial role to play in the formation, consolidation and perpetuation of the human sense of place, contributing vitally and in various ways to evolving ideas of landscape and the human spatial experience.
Typification of the accepted names in the variable species Anarrhinum fruticosum Desf. (Antirrhineae, Plantaginaceae)
Adansonia 43 (4)
Anarrhinum fruticosum Desf. (Antirrhineae, Plantaginaceae) is a very variable species. Three subspecies are currently recognized: A. fruticosum subsp. fruticosum, A. fruticosum subsp. brevifolium (Cosson & Kralik) D.A. Sutton (synonym of A. brevifolium Cosson & Kralik), and A. fruticosum subsp. demnatense (Cosson) Maire (synonym of A. demnatense Cosson). Anarrhinum brevifolium was recently typified by Domina & El Mokni (2019), while these other two names are discussed and lectotypified in the present paper. Lectotypes are designated from an illustration published by Desfontaines (A. fruticosum), and a specimen from P-Cosson herbarium (A. demnatense).
Le Jurassique du Jebel Ressas (Tunisie). Identification du Sinémurien supérieur dans la Formation Zaghouan. Précisions stratigraphiques et paléobiogéographiquessur le Sinémurien de Tunisie
Geodiversitas 43 (4)
The revision of the Jurassic lithostratigraphic succession of Jebel Ressas Jurassic (Tunisian Dorsal, Tunisia) allows us to identify all the formations already defined in the Tunisian Dorsal. The Zaghouan Formation is newly dated by Upper Sinemurian ammonites belonging to the Obtusum (Stellare subchronozone) and Raricostatum (Raricostatum Subchronozone) chronozones. Six Ammonitina taxa belonging to the genera Asteroceras (A. gr. saltriense (Parona, 1896), A. cf. meridionalis Dommergues, Meister & Mettraux, 1990), Arnioceras (A. gr. ceratitoides (Quenstedt, 1849) – rejectum Fucini, 1902), Epophioceras (E. cf. landrioti (d’Orbigny, 1850)) et Paltechioceras (P.
Out on a limb: novel morphology and position on appendages of two new genera and three new species of ectoparasitic isopods (Epicaridea: Dajidae) infesting isopod and decapod hosts
Zoosystema 43 (4)
Adult female dajid isopods are ectoparasites found on carapaces, within marsupia, or rarely attached to the eyestalks or pereopods of crustacean hosts. We describe two new genera and species whose females exhibit a novel spheroid shape and envelope antennules of hosts: Akrophryxus milvus n. gen., n. sp. parasitizing Ethusa machaera Castro, 2005 (Madagascar, c. 900 m) and Telephryxus clypeus n. gen., n. sp. parasitizing Munidopsis crassa Smith, 1885 (Caribbean, c. 5000 m). Females of both species differ from other dajid species in their spheroid shape and a plate partially surrounding the host antennule; males are distinguished by reduction of pereopods. Females of A. milvus n. gen., n. sp.
