A new species, Lappula botschantzevii, is described from the desert zone of North-Western Africa. The new species belongs to the section Lappula and is close to the species L. patula, from which it differs in a smaller corolla, a scorpioid inflorescence (bilateral flowers) with loosely spaced flowers, a heteromorphic coenobium with two types of eremocarps: A) winged with glochids and a large number of spines along the edges of the disc of eremocarps and B) with a second short row of spines. The species is described based on samples from collections housed in three herbaria: Herbarium of the Komarov Botanical Institute RAS, Sankt-Peterburg (LE, Russia) and Muséum National d ‘Histoire Naturelle, Paris (P, France), Université de Montpellier (MPU). It is named after the Russian botanist Viktor Petrovich Botschantzev, who spent many years studying the flora of Africa and who collected samples of the new species. The absence of holotypes required the typification of the names of the studied species Lappula patula, L. capensis and L. eckloniana.

AbstractA recent discovery of freshwater sponges in an unexplored hydrographic basin in north-western Australia provided the opportunity to investigate the genus Corvospongilla Annandale (Spongillida: Spongillidae) using integrative systematics. Emendation of the genus diagnosis is provided. A comparative analysis of a Corvospongilla global dataset of morphological traits together with biogeographic patterns disclosed a new Australasian Corvospongilla species and along with molecular analyses provided the basis for a phylogenetic and phylogeographic tree for some Asian, Afrotropical and Australasian lineages.

A new species of Synelmis (Annelida: Polychaeta: Pilargidae), Synelmis urgorrii sp. nov., is described from the continental slope off north-western Spain. The new species is characterized by having antennae, peristomial cirri and parapodial cirri cirriform, lateral antennae located in the proximal third of the prostomium, notospines starting on chaetigers 7–11, well-developed neuropodial lobe and asymmetrical furcate chaetae, those of anterior chaetigers distinctly spinulated.

A new species of Terebellidae, Pistacolinisp. n., has been identified from the harbour of Banyuls-sur-Mer, north-western Mediterranean Sea. This new species was found in very high densities, exclusively in gravelly sand deposited manually, and was not found in the original source habitat of the gravel. This species is characterized by the colour of the ventral shields with pinkish anterior part and a blood red posterior part in live specimens, a pair of unequal-sized plumose branchiae inserted on segment II and anterior thoracic neuropodia with long-handled uncini. The presence of long-handled uncini even in the smallest specimens constitutes the major difference between Pistacolinisp. n. and other Pista species with a single pair of branchiae such as P.lornensis and P.bansei.

AbstractThe type material of most European nominal species previously placed in Rhoptromeris and of some other species is studied. Notes are given on the type material, 10 lectotypes are designated and the identity of the species is discussed. Three valid Rhoptromeris species are found: R. heptoma (Hartig) [type species], R. villosa (Hartig) and R. rufiventris (Giraud) n.comb. The latter is the type species of Hexamerocera Kieffer which is synonymized with Rhoptromeris. The genus Rhoptromeris is described and compared with related genera. The three species found to be valid are figured and redescribed, and also a new species, R. nigriventris, is described from Sweden. R. heptoma is an important parasitoid of Oscinella frit (L.) (Dipt.: Chloropidae).

Abstract. Isolated chitinozoans from the Soom Shale Member of the Cedarberg Formation, SW South Africa are described and provide a date of the latest Hirnantian–earliest Rhuddanian. The recovered chitinozoans are typical of the latest Ordovician Spinachitina oulebsiri Biozone, although an earliest Silurian age is possible. They indicate a very short time span (less than 1 Ma) across the Ordovician–Silurian boundary. This is currently the highest biostratigraphical resolution attainable for the Soom Shale Lagerstätte. Correlation of the Soom Shale chitinozoans with identical assemblages in post-glacial, transgressive deposits of Northern Africa is possible; both faunas occur in shales that overlie glacial diamictites of the Hirnantian glaciation. A new species, Spinachitina verniersi n. sp. is described.

We describe a new species of drongo in the Square-tailed Drongo (Dicrurus ludwigii) complex using a combination of biometric and genetic data. The new species differs from previously described taxa in the Square-tailed Drongo complex by possessing a significantly heavier bill and via substantial genetic divergence (6.7%) from its sister-species D. sharpei. The new species is distributed across the gallery forests of coastal Guinea, extending to the Niger and Benue Rivers of Nigeria. We suspect that this taxon was overlooked by previous avian systematists because they either lacked comparative material from western Africa or because the key diagnostic morphological character (bill characteristics) was not measured. We provide an updated taxonomy of the Square-tailed Drongo species complex.

A new genus Burmanyctycia gen. n. is described for the new species Burmanyctycia naumanni sp. n. from Chin State in north-western Myanmar. The new genus is related to the genera Blepharomima Hreblay & L. Ronkay, 1998, Bryotypella Hreblay & L. Ronkay, 1998 and Charanyctycia Hreblay & L. Ronkay, 1998. Two new synonyms are established: Bryotypella = Paranyctycia Hreblay & L. Ronkay, 1998, syn. n. and Bryotypella = Parabole Hreblay & L. Ronkay, 1998, syn. n. Six new combinations are established: Bryotypella minima (Hreblay & L. Ronkay, 1999), comb. n., Bryotypella miraculosa (Hreblay, Peregovits & L. Ronkay, 1999), comb. n., Bryotypella orbiculosa (Hreblay & L. Ronkay, 1998), comb. n., Bryotypella rubiculosa (Hreblay & Ronkay, 1999), comb. n., Bryotypella medionigra (Hreblay & Ronkay, 1998), comb. n. and Bryotypella rectilinea (Hreblay & L. Ronkay, 1998), comb. n. The check-lists of the genera Bryotypella and Charanyctycia are provided. Adults, male and female genitalia of the new and the related taxa are illustrated.

AbstractA new species of Hypolophites (Chondrichthyes, Myliobatiformes) is described from an assemblage of isolated pavement teeth recovered from the Lower Clayton Limestone Unit of the Midway Group (Paleocene) near Malvern, Arkansas. These teeth were collected from several localized lag deposits containing an abundance of chondrichthyan and osteichthyan teeth, invertebrate remains, and trace fossils indicative of a marginal-shallow marine depositional environment. To date, only four additional species of Hypolophites have been reported from Paleocene deposits that occur along the west coast of central-northern Africa and in central New Jersey, USA. The identification of Hypolophites beckeri n. sp. in southwestern Arkansas extends the distribution of this biostratigraphically significant genus ~1,750 km westward into the Mississippi Embayment and Gulf Coastal Plain of the USA. The distribution of Hypolophites species during the Paleocene attests to the uniformity of shallow marine shelves between western Africa and the Atlantic and Gulf Coastal Plains of the USA, as well as myliobatiform diversification following the K/Pg mass extinction event.UUID: http://zoobank.org/3a1580d1-a2f4-49b6-8170-69a778c49181

During a biodiversity survey of Alternaria associated with leaf spot and blight of Solanaceae, a large collection of strains was obtained from samples collected in north-western regions of Algeria in 2013–2018 growing seasons. Amongst these strains, three isolates recovered from tomato and potato had morphological traits different from that usually observed for Alternaria species previously reported on Solanaceae. Based on analysis of a sequence dataset corresponding to portions of the glyceraldehyde-3-phosphate dehydrogenase (gpd), translation elongation factor 1-alpha (tef1) and RNA polymerase second largest subunit (rpb2) genes along with morphological observations, isolates were identified as a new species in the section Japonicae. This novel species, described here as Alternaria telliensis, is phylogenetically and morphologically distinct from A. japonica and A. nepalensis in this section. Pathogenicity tests were performed and isolates were found to be weakly pathogenic to tomato and potato (Solanaceae) while highly aggressive on radish, cabbage and turnip (Brassicaceae) plants.
