Vittalia mangrovei, gen. nov., sp. nov. (Phaeosphaeriaceae) from mangroves near Pondicherry (India), based on morphology and multigene phylogeny
Cryptogamie, Mycologie 40 (7)
Collection and examination of decaying wood samples of Avicennia marina (Forssk.) Vierh. from Pondicherry mangroves, India, resulted in the discovery of a novel monotypic genus Vittaliana, based on the type species V. mangrovei, which shares close morphological affinities with Italica Wanas., Camporesi & K.D.Hyde and Phaeosphaeriopsis M.P.S. Câmara, M.E. Palm & A.W. Ramaley. The concatenated LSU, SSU, TEF1α and ITS multigene phylogenetic analyses revealed that the new genus clustered together with Italica as a sister clade but forms a separate branch. In addition, morphological variations in Vittaliana mangrovei Devadatha, Nikita, A.Baghela & V.V.Sarma, gen. nov., sp.
Customs, rites, and sacrifices relating to a mortuary complex in Late Bronze Age Mongolia (Tsatsyn Ereg, Arkhangai)
Anthropozoologica 54 (15)
Deer stone and khirigsuur complexes are monuments that are characteristic of the Late Bronze Age (1200-700 BC) of the steppes of central and northern Mongolia. The khirigsuurs are made up of a large central mound around which are distributed peripheral structures: mounds and circles of stones. The peripheral mounds cover heads, vertebrae and phalanges of horses. At the centre of the circles of stones, the deposits consist of the burnt bones of caprines. This article discusses the ingredients that will allow us to better understand the gestures performed as part of the activities around the ritual monuments at Tsatsyn Ereg (Mongolia).
New Amphicyonids (Mammalia, Carnivora) from Moghra, Early Miocene, Egypt
Geodiversitas 41 (21)
We describe two large amphicyonid (Amphicyonidae, Carnivora) mandibles from Moghra, Early Miocene, Egypt. One of these represents a new species of Cynelos Jourdan, 1862, which is in the same size range as C. macrodon (Savage, 1965) and C. ginsburgi n. comb., but exhibits a relatively longer m1 paraconid blade. The other is allocated to Amphicyon giganteus (Schinz, 1825). Based on this new material the differences between Cynelos, Amphicyon Lartet in Michelin, 1836, and Afrocyon Arambourg, 1961 are clarified. We also reassign three (P4, M1, M2) of four isolated and unassociated amphicyonid teeth from Moghra, previously attributed to “Cynelos sp. nov.” to Amphicyon giganteus.
Les apports des sciences participatives à la connaissance naturaliste : le cas de l’enquête participative « Lichens forestiers du Massif central »
Naturae 2019 (9)
From 2015 to 2016, some scientific and institutional structures got involved to set up and implement a participatory project on lichens impulsed by the DREAL Auvergne-Rhône-Alpes (the local representation for the French ministry of environment) focused on several lichens species : Lobaria pulmonaria (L.) Hoffm., L. scrobiculata (Scop.) DC., Sphaerophorus globosus (Huds.) Vain., S. fragilis (L.) Pers., Xanthoria parietina (L.) Th. Fr., Flavoparmelia sp., Usnea sp. et Ramalina fraxinea (L.) Ach. The so-called “Participatory survey on forest lichens in Massif-Central” enabled to collect almost 3000 occurrence data, including validated observations of new species in some parts of the project area.
A small elevational gradient shows negative bottom-to-top bryophyte richness in a seasonally dry forest in Brazil
Cryptogamie, Bryologie 40 (17)
Elevational gradients can serve as powerful tools for testing ecological relationships between species richness versus environmental variables. Although the patterns be usually from positive to humped-shaped, elevational gradients may run in a negative way with the species richness decreasing in relation to the altitude. The floristic gradient may vary according species biology, site and, scale for analyses. Therefore, elevational gradient can be useful for detecting points for biological conservation and may be analized by using sensitive species as approach for others species including banner-species. Along an elevational gradient in a harsh semiarid environment we are showing a negative relationship between bryophyte species richness and increasing elevation.
Redescription of two overlooked species of the Perinereis nuntia complex and morphological delimitation of P. nuntia (Savigny in Lamarck, 1818) from the Red Sea (Annelida, Nereididae)
Zoosystema 41 (24)
Two poorly-known species are systematically studied in detail: Nereis (Nereis) latipalpa Schmarda, 1861 from Cape Town, South Africa, and Nereis (Neanthes) larentukana Grube in Peters, 1881 from Larantuka, Flores, Indonesia. Both are raised from synonymy and transferred to the Perinereis nuntia species complex based upon the revision of type material using characters already known, novel, or even forgotten in the literature. Perinereis latipalpa n. comb. is different from its previous senior synonym P. vallata (Grube & Kröyer in Grube, 1858) and related species. The type or topotype specimens of three other nereidid species share the same relevant features as P. latipalpa n.
Restes inédits de rongeurs caviomorphes du Paléogène de la région de Juanjui (Amazonie péruvienne) : systématique, implications macro-évolutives et biostratigraphiques
Geodiversitas 41 (20)
Paleogene deposits of Peruvian Amazonia have yielded the oldest caviomorph rodent communities from South America, and the clues that their early diversification had occurred in this area. Here we report fossil dental remains of rodents from two new sections located in the vicinity of Juanjui and Balsayacu (San Martín Department, Peruvian Amazonia).
Updated checklist of French Guianan Asilidae (Diptera) with a focus on the Mitaraka expedition

This paper documents the robber fly fauna collected in lowland rainforest in the southwesternmost part of French Guiana (Mitaraka). A total number of 146 asilid specimens were collected during the Mitaraka 2015 survey. These asilids represent six subfamilies, 23 genera, 16 described species, 28 morphospecies, and first records of 12 genera and 29 species for French Guiana.
Revision of Chondrocyclus s.l. (Mollusca: Cyclophoridae), with description of a new genus and twelve new species
European Journal of Taxonomy 2019 (569)
Chondrocyclus Ancey, 1898 is a genus of nine species of African operculate land snails restricted to indigenous forest and mesic thicket. Worn specimens (i.e., without a periostracum or operculum), on which some species descriptions and records were based, appear to be indistinguishable morphologically. A comprehensive revision of Chondrocyclus s.l. is provided here based on comparative morphological examinations of the shell, protoconch, periostracum, operculum, radula and penis, and on mitochondrial genes cytochrome c oxidase subunit I and 16S rRNA. Two genus-level lineages are recognised, Chondrocyclus s.s. and Afrocyclus gen. nov. Revised species descriptions are given for seven species.
A new species of Bufonia L. (Caryophyllaceae) from the Kordestan province (Iran)
Adansonia 41 (13)
During investigation of the genus Bufonia L., in various herbaria of Iran, a new species, B. iranica Z.Rostami, Assadi & F.Ghahrem., sp. nov., was recognized and thus is described here. This new species is closely related to B. enervis, with some morphological differences such as size and shape of the perianth, and the seed shape. A key for the species occurring in Iran, illustrations and a distribution map of the new and related species are provided. The seed morphology was studied using a scanning electron microscope.
New data on the morphology, reproduction and distribution of a freshwater brown alga Porterinema fluviatile (Porter) Waern (Phaeophyceae)
Cryptogamie, Algologie 40 (9)
This paper provides information on the morphology, reproduction and distribution of a freshwater brown alga, Porterinema fluviatile (Porter) Waern (Phaeophyceae). The alga was recorded in oligotrophic water from Mlava Spring, a karst limnocrene in eastern Serbia (44°11’298”N, 21°47’021”E). This is the first record of freshwater brown algae in general in Serbia, and the first record of P. fluviatile in southeastern Europe. The thallus of P. fluviatile formed small, dark-brown tufts, with multicellular, uniseriate filaments that were irregularly branched. An anastomosis was noticeable between some filaments. The vegetative cells of the young filaments were cylindrical (17-38 μm long × 2.5-4.0 μm wide). The cells had 1 or 2, rarely 3, plate-like parietal plastids.
Asterolepis alticristata n. sp. (Antiarchi) from the Upper Devonian (Frasnian) of Nunavut, Canada, and a report on the antiarch diversity of the Fram Formation
Geodiversitas 41 (19)
A large collection of fossils from the NV2K17 locality, Upper Devonian (Frasnian) Fram Formation, Ellesmere Island, Nunavut, Canada, represents at least two species of Asterolepis. The first, Asterolepis alticristata n. sp., is diagnosed by a tall midline crest that rises sharply from the tergal angle of the anterior median dorsal plate, reaches maximum height at around the position of the lateral corners, and then drops to form a low midline crest along the posterior median dorsal plate. The second species is identified as Asterolepis cf. radiata according to an ornament of radiating rows of conjoined tubercles and ridges on the available thoracic plates (anterior median dorsal, posterior median dorsal, and mixilateral).
