| BackgroundSchistosomiasis is neglected tropical parasitic disease affecting both humans and animals. Due to the human health impact, population genetic studies have focused on the three main human-infecting schistosome species: Schistosoma mansoni, S. haematobium and S. japonicum. Here we present novel data on the population genetic structure of Schistosoma bovis, a highly widespread and prevalent schistosome infecting ruminants, and therefore of veterinary importance.MethodsAdult S. bovis were sampled in the two main abattoirs of Cameroon (Yaounde and Douala). Twenty-two cows originating from four distinct localities were sampled and a total of 218 parasites were recovered. All parasites were genotyped using a panel of 14 microsatellite markers and a... |

| The brown alga Lobophora (Dictyotales, Phaeophyceae) is an important macroalga in the North‐eastern Atlantic archipelagos (i.e., Macaronesia). Notably in the Canaries it can dominate benthic assemblages. While the genus has been the subject of several ecological studies in the Canaries, no study has yet been conducted to assess species‐level diversity of Lobophora in Macaronesia. We reassessed the diversity of Lobophora in Macaronesia, reporting the presence of seven species (L. caboverdeana sp. nov., L. canariensis, L. dagamae sp. nov., L. delicata, L. dispersa, L. littlerorum, and L. schneideri). Lobophora spp. from Macaronesia are morphologically and ecologically distinguishable. In the Canaries, L. schneideri dominates the photophilic assemblages from... |

| In this review (third part), several species within the Nassarius pauperus complex from the eastern Indian Ocean and western Pacific are treated, including a revised concept of Nassa paupera Gould, 1850, type species of the genus Reticunassa Iredale, 1936. In the most recent taxonomic revision, several species had been synonymized with Nassarius pauperus (Gould, 1850), despite distinctive differences among these species in shell morphology. We sequenced a fragment of the mitochondrial COI and the nuclear 28S genes of all available Nassarius pauperus complex species. Automatic barcode gap discovery and reciprocal monophyly were applied to propose species delimitation hypotheses and to support a new concept of the genus. Using morphological and molecular... |

| Four new species of Hohenbuehelia (Fungi: Pleurotaceae) are described in the group of Hohenbuehelia atrocoerulea and Hohenbuehelia grisea. Hohenbuehelia algonquinensis, found on Pinus in Ontario, Canada, may be distinguished macroscopically from bluish collections of H. atrocoerulea and watery grey-brown collections of H. grisea by its coal-black pileus. Hohenbuehelia canadensis, on or associated with Pinus in both Ontario and Alberta, Canada, and Hohenbuehelia nimueae, on Salix in Ontario and Abies in Wyoming, USA, have similarly dark fruiting bodies and were previously misidentified as H. approximans (which we treat as a synonym of H. grisea), H. atrocoerulea, H. mustialensis or H. nigra. The latter species is shown to be a member of Resupinatus, despite... |

| In this paper we describe a new apochelan species, Milnesium variefidum sp. nov. from Scotland and provide novel morphological and molecular data for Milnesium berladnicorum Ciobanu et al., 2014. The new species differs from the most similar M. berladnicorum by the presence of developmental dimorphism in claw configuration, absent or weakly developed cuticular bars under claws I-III, a different arrangement of cuticular pseudoplates, and by differences in the sequences of three nuclear DNA fragments: 18S rRNA (p-distance: 0.6%), 28S rRNA (2.0%), ITS-2 (9.3%), and on mitochondrial gene COI (12.4%). Although ontogenetic claw configuration change was suspected to occur in some Milnesium species, we are the first to document it through the combined use of... |
