| Numerous members of Ascomycota and Basidiomycota produce only poorly differentiated arthroconidial asexual morphs in culture. These arthroconidial fungi are grouped in genera where the asexual-sexual connections and their taxonomic circumscription are poorly known. In the present study we explored the phylogenetic relationships of two of these ascomycetous genera, Arthrographis and Arthropsis. Analysis of D1/D2 sequences of all species of both genera revealed that both are polyphyletic, with species being accommodated in different orders and classes. Because genetic variability was detected among reference strains and fresh isolates resembling the genus Arthrographis, we carried out a detailed phenotypic and phylogenetic analysis based on sequence data of... |

| The family Archimonocelididae Meixner, 1938 has been revised. The family contains two subfamilies, each comprising two genera: the Archimonocelidinae with Archimonocelis Meixner, 1938 and Meidiama Marcus, 1946, and the Calviriinae subfam. nov. with Asilomaria Karling, 1966 and Calviria gen. nov. with 20, 2, 1, and 3 species, respectively, 13 of which are new to science. The type species of the family is redescribed. Material of all the Archimonocelididae genera has been studied and supplementary remarks are made on some known species. The karyotype of 14 species is described. Archimonocelis has a cosmopolitan distribution while Meidiama is restricted to the South American coast, Calviria to the Mediterranean, and Asilomaria to the Pacific North American... |

| Diaporthe (syn. Phomopsis) species are well-known saprobes, endophytes or pathogens on a range of plants. Several species have wide host ranges and multiple species may sometimes colonise the same host species. This study describes eight novel Diaporthe species isolated from live and/or dead tissue from the broad acre crops lupin, maize, mungbean, soybean and sunflower, and associated weed species in Queensland and New South Wales, as well as the environmental weed bitou bush (Chrysanthemoides monilifera subsp. rotundata) in eastern Australia. The new taxa are differentiated on the basis of morphology and DNA sequence analyses based on the nuclear ribosomal internal transcribed spacer region, and part of the translation elongation factor-1α and ß-tubulin... |

| Cladosporium is mainly known as a ubiquitous environmental saprobic fungus or plant endophyte, and to date, just a few species have been documented as etiologic agents in vertebrate hosts, including humans. In the present study, 10 new species of the genus were isolated from human and animal clinical specimens from the USA. They are proposed and characterized on the basis of their morphology and a molecular phylogenetic analysis using DNA sequences from three loci (the ITS region of the rDNA, and partial fragments of the translation elongation factor 1-alpha and actin genes). Six of those species belong to the C. cladosporioides species complex, i.e., C. alboflavescens, C. angulosum, C. anthropophilum, C. crousii, C. flavovirens and C. xantochromaticum,... |

| The eulophid genus Parzaommomyia Girault, 1915, is revised and redefined. Five new species are described and illustrated: P. sulensis spec. nov. from Sulawesi and West Malaysia, P. africana spec. nov. from Nigeria, P. crassicornis spec. nov. from Sulawesi, New Guinea and China, P. achterbergi spec. nov. from East Malaysia and Java, and P. incompleta spec. nov. from New Guinea. Species of this genus represent a monophyletic Palaeotropical group characterized by six synapomorphies according to the results of the cladistic analysis of all known (six) species and 20 outgroup taxa coded for twenty-nine characters. The supraclypeal area is delimited by grooves (i. e. both the clypeus and the supraclypeus are delimited), the sensory pores on the scape of the male... |

| Species delineation remains one of the most challenging tasks in the study of biodiversity, mostly owing to the application of different species concepts, which results in contrasting taxonomic arrangements. This has important practical consequences, since species are basic units in fields like ecology and conservation biology. We here review molecular genetic evidence relevant to the systematics of toads in the Bufo bufo species group (Anura, Bufonidae). Two studies recently published in this journal (Recuero et al., MPE 62: 71–86 and Garci´a-Porta et al., MPE 63: 113–130) addressed this issue but reached opposing conclusions on the taxonomy of the group (four versus two species). In particular, allozyme data in the latter paper were interpreted as... |

| Phylogenetic analyses of Microstegium (Andropogoneae, Poaceae) and some other Andropogoneae species were conducted inferred from the ITS/5.8S sequences. As a result of this study, Microstegium is polyphyletic. There are two rather distant monophyletic clades, one with Microstegium nudum (type of Leptatherum), M. japonicum and M. somae, the other one with M. ciliatum, M. fauriei, M. geniculatum and M. vimineum (type of Microstegium). Therefore we feel justified to reinstate the genus Leptatherum and three new combinations, Leptatherum boreale, L. nudum and L. somae, are proposed. |

| Dothiorella and Spencermartinsia are two botryosphaeriaceous genera with dark 2-celled conidia and found in parasitic, saprophytic or endophytic association with various woody host plants. Based on ITS and EF1-α sequence data and morphology, eight new species are described from Iran, New Zealand, Portugal and Spain. Of these, five species are placed in Dothiorella, namely D. iranica, D. parva, D. prunicola, D. sempervirentis and D. striata, and three species belong to Spencermartinsia named as S. citricola, S. mangiferae and S. plurivora. An identification key to the species of each genus is provided. |

| 1. A phylogenetic hypothesis for the triclads is presented and the characters on which it is based are discussed. 2. The sister group of the Tricladida is formed by the Bothrioplanida, and together the two taxa share a sistergroup relationship with the Proseriata. 3. The monophyletic status of the suborder Tricladida is supported by several derived features (Fig. 1., characters 9—12), including a unique embryological development and the presence of a marginal adhesive zone. 4. It is postulated that the Maricola is the primitive sister group of the Terricola and the Paludicola together and that the Paludicola represents the most advanced group within the Tricladida. Characters supporting these hypotheses are discussed (Fig. 1, characters 14-16, and 20-22,... |

| Three species of Mycosphaerella, namely M. eumusae, M. fijiensis, and M. musicola are involved in the Sigatoka disease complex of bananas. Besides these three primary pathogens, several additional species of Mycosphaerella or their anamorphs have been described from Musa. However, very little is known about these taxa, and for the majority of these species no culture or DNA is available for study. In the present study, we collected a global set of Mycosphaerella strains from banana, and compared them by means of morphology and a multi-gene nucleotide sequence data set. The phylogeny inferred from the ITS region and the combined data set containing partial gene sequences of the actin gene, the small subunit mitochondrial ribosomal DNA and the histone H3... |

| Plectosphaerella cucumerina, most frequently encountered in its Plectosporium state, is well known as a pathogen of several plant species causing fruit, root and collar rot, and collapse. It is considered to pose a serious threat to melon (Cucumis melo) production in Italy. In the present study, an intensive sampling of diseased cucurbits as well as tomato and bell pepper was done and the fungal pathogens present on them were isolated. Phylogenetic relationships of the isolates were determined through a study of ribosomal RNA gene sequences (ITS cluster and D1/D2 domain of the 28S rRNA gene). Combining morphological, culture and molecular data, six species were distinguished. One of these (Pa. cucumerina) is already known. Four new species are described as... |

| We sequenced the mitochondrial barcoding marker COI and nuclear marker EF1-alpha for most Nordic and other European species of the Stigmella salicis and S. aurella species groups. In the S. salicis group both markers confirm the synonymy of S. lappovimella with S. zelleriella. Specimens previously identified as Stigmella salicis and S. vimineticola are shown to form a complex of several cryptic species for which the taxonomy needs to be worked out. The species previously recorded as S. vimineticola from Norway represents probably an unnamed species. In the S. aurella group, the oligophagous Rosaceae feeders S. aurella and S. poterii are confirmed to be each a single oligophagous species. The synonymy between Stigmella ulmariae from Filipendula ulmaria and... |

| An extensive molecular phylogenetic reconstruction of the suborder Zygoptera of the Odonata is presented, based on mitochondrial (16S, COI) and nuclear (28S) data of 59% of the 310 genera recognized and all (suspected) families except the monotypic Hemiphlebiidae. A partial reclassification is proposed, incorporating morphological characters. Many traditional families are recovered as monophyletic, but reorganization of the superfamily Coenagrionoidea into three families is proposed: Isostictidae, Platycnemididae and Coenagrionidae. Archboldargia Lieftinck, Hylaeargia Lieftinck, Palaiargia Forster, ¨ Papuargia Lieftinck and Onychargia Selys are transferred from Coenagrionidae to Platycnemididae, and Leptocnemis Selys, Oreocnemis Pinhey and Thaumatagrion... |
