Thanks to recent developments in molecular methods, many new species have been discovered within the genus Circovirus, which comprises viruses of veterinary relevance found in a broad range of hosts. In particular, several circoviruses are known to infect birds, often causing immunosuppression and feathering disorders. Nonetheless, nothing is known about their circulation in birds of prey. In this study, samples from 61 birds of prey representing ten different species, recovered by a wildlife rescue centre in Southern Italy, were taken at necropsy and analysed by PCR with pan-Circovirus primers. Only one sample, collected from a tawny owl (Strix aluco), tested positive. Its genome, sequenced by primer walking, displays the typical features of circoviruses. Based on demarcation criteria, the detected strain qualifies as a novel species, which was named “tawny owl-associated circovirus” (ToCV). Phylogenetically, ToCV clustered with mammalian rather than avian circoviruses, and its closeness to a rodent circovirus suggests that its host may have been a micromammal eaten by the tawny owl. On the other hand, its detection in the spleen fits with the tropism of other avian circoviruses. Little can be therefore said on its biology and pathogenicity, and further efforts are needed to better characterize its epidemiology.

The endophytic Talaromyces omanensis sp. nov., a new microfungus isolated from the desert plant Rhazya stricta in Oman, is described and illustrated. The new species forms a distinct sister clade to the section Subinflati in the phylogeny of internal transcribed spacer (ITS), β-tubulin (benA) and Calmodulin (CaM). Talaromyces omanensis remains distinct and unique from the other species in the section Subinflati in having monoverticillate conidiophores.

Four additional species of quill mites of the family Syringophilidae Lavoipierre have now been recorded in England. This includes one new species, Bubophilus aluconis sp. nov., which parasitizes the tawny owl Strix aluco (Strigiformes: Strigidae). It differs from other species of this genus, B. ascalaphus Philips et Norton, 1978 and B. asiobius Skoracki et Bochkov, 2002 by the number of chambers in transverse branch of the peritremes (2-3), the length ratio of setae vi and ve (1:1.6-2), and the lengths of the stylophore and aggenital setae ag1 (180 and 135-145, respectively).

The project ANDEEP was designed to fill gaps in the knowledge of the biodiversity of the Southern Ocean deep sea. Threeoceanographic cruises (ANDEEP I, II and III) were undertaken in 2002 and 2005 in the Atlantic Sector of the SouthernOcean. Hundreds of samples were collected from 40 stations with water depths ranging from 748 to 6,348 m. Investiga-tions were carried out on a broad range of taxa, including bacteria, meio-, macroand megafauna. Approximately 5000ostracods were collected, which included 29 specimens of Doloria (Dolorietta) subgen. nov.The subdivision of the genus Doloria Skogsberg, 1920 into two subgenera, Doloria (Doloria) and the novel subgenusDoloria (Dolorietta), is based on differences in the structures of the fifth limb, the armature of the sensory bristle on the5th segment of the antennula, and the number of bristles on the 4th endite of the sixth limb. Four new species in the newsubgenus were identified from the ANDEEP samples. The new subgenus and the four novel species are described andillustrated. Two of these new species are named Doloria (Dolorietta) antarctica sp. nov. and Doloria (Dolorietta) sextafiliformis sp. nov., but the other two species are left in open nomenclature (i.e. Doloria (Dolorietta) sp. nov. 1 and Doloria(Dolorietta) sp. nov. 2) because only juveniles were found in our material. Keys to the subgenera and species of Doloria are provided.

Seven new species and one new subspecies of the genus Strandesia s.l. Stuhlmann, 1888, are described. Four species reared by Sars (1901) from dried mud from Brazil are redescribed. The genera Acanthocypris Claus, 1892, and Neocypris Sars, 1901, are considered as subgenera of Strandesia s.l. Two species from Europe, formerly attributed to Cypricercus Sars, 1895, are redescribed. One of these, C. obliquus (Brady, 1868) was used as type-species for the erection of a new tribe and of the genus Bradleycypris by McKenzie (1982), but proves to be a member of the subgenus Neocypris of Strandesia s.l. Therefore Bradleycypris becomes a subjective synonym of Neocypris. On the other hand, Cypricercus fuscatus (Jurine, 1820) effectively shows the characters used by McKenzie for the characterization of Bradleycypris, and is selected here as type-species of the new genus Bradleystrandesia.

There is a growing diversity of bat-associated lyssaviruses in the Old World. In August 2017, a dead Brandt’s bat (Myotis brandtii) tested positive for rabies and based on partial sequence analysis, the novel Kotalahti bat lyssavirus (KBLV) was identified. Because the bat was in an autolyzed state, isolation of KBLV was neither successful after three consecutive cell passages on cells nor in mice. Next generation sequencing (NGS) was applied using Ion Torrent ™ S5 technology coupled with target enrichment via hybridization-based capture (myBaits®) was used to sequence 99% of the genome, comprising of 11,878 nucleotides (nt). KBLV is most closely related to EBLV-2 (78.7% identity), followed by KHUV (79.0%) and BBLV (77.6%), supporting the assignment as phylogroup I lyssavirus. Interestingly, all of these lyssaviruses were also isolated from bat species of the genus Myotis, thus supporting that M. brandtii is likely the reservoir host. All information on antigenic and genetic divergence fulfil the species demarcation criteria by ICTV, so that we recommend KBLV as a novel species within the Lyssavirus genus. Next to sequence analyses, assignment to phylogroup I was functionally corroborated by cross-neutralization of G-deleted RABV, pseudotyped with KBLV-G by sera from RABV vaccinated humans. This suggests that conventional RABV vaccines also confer protection against the novel KBLV.

The Aphyosemion calliurum species group is poorly diagnosed by chromatic and meristic characteristics leading various authors to propose different species as members. We used partial sequence of the mitochondrial cytochrome b gene to characterize all species that have been at one time or another included in the A. calliurum species group. Results obtained allowed a clear definition of the group which is composed of 10 species: A. ahli, A. australe, A. calliurum, A. celiae, A. edeanum, A. franzwerneri, A. heinemanni, A. lividum, A. pascheni, and a herein newly described species A. campomaanense. This new species is described from 26 specimens captured in small streams of the Campo-Ma’an region within the Ntem River basin of southern Cameroon. A. campomaanense n. sp. is distinguished from all the other species of the A. calliurum species group, and above all from A. ahli, by asymmetric coloration of the caudal fin with a yellow lower margin and a white upper margin, and a body with a dark blue background against which red spots are arrayed in horizontal rows towards the head merging into vertical rows posteriorly. This species is also genetically distinguished from the other species of the A. calliurum species group by its mitochondrial genome and its karyotype, characterized by an unusually high number of chromosomes and arms (2n= 44, NF=58).

Two new hyphomycetes, Paradictyoarthrinium aquatica and P. hydei were collected and isolated from submerged wood and decaying wood in China and Thailand respectively. Morphologically, they line well with Paradictyoarthrinium in having superficial, gregarious, black, powdery fruiting bodies, macronematous conidiophores with unevenly dictyoseptate, muriform, subglobose to ellipsoidal dark brown conidia, but they differ from the other species in having short conidiophores. Phylogenetic analysis of combined LSU, ITS and RPB2 sequence data showed that six taxa of Paradictyoarthriniaceae, including the two new species, form a monotypic clade among the phylogenetically close families in Pleosporales with good support. Six isolates of Paradictyoarthrinium formed four distinct clades and represent four different species. Detailed descriptions and illustrations of the new species are provided, as well as the comparisons with related taxa.

Abstract In this study, we investigated the diversity of diatrypaceous fungi from six regions in China based on morpho-molecular analyses (maximum parsimony, maximum likelihood and Bayesian inference analyses of combined ITS and tub2 gene regions). We accept 24 genera in Diatrypaceae with 19 genera involved in the phylogram and the other five genera are lacking living materials with available sequences. Eleven species include in four genera (viz. Allocryptovalsa, Diatrype, Eutypella and Allodiatrypella gen. nov.) have been isolated from seven hosts species, of which ten novel species (Allocryptovalsa castanea, Allodiatrypella betulae, A. betulicola, A. betulina, A. hubeiensis, A. xinjiangensis, Diatrype betulae, D. castaneicola, D. quercicola and Eutypella castaneicola) are introduced in this study, while Eutypella citricola is a new record from Morus host. Current results show the high diversity of members of Diatrypaceae species which are wood-inhabiting fungi in China.
