Abstract Based on molecular phylogenetic analyses of a multigene matrix of partial nuSSU-ITS-LSU rDNA, RPB1, RPB2 and TEF1 sequences and by morphological evidence, the genus Mycosphaerangium is shown to be the closest relative of Neomelanconium, and confirmed to be a member of the Cenangiaceae (Leotiomycetes). While Mycosphaerangium and Neomelanconium share many traits like similar conidia, conidiogenesis, asci and ascospores, their apothecia differ particularly in excipular features and are therefore recognized as distinct genera. Mycosphaerangium tiliae, described from North America, is excluded from the genus but shown to represent the sexual morph of the European Neomelanconium gelatosporum, and it is therefore synonymized with the latter. Based on morphology, Neomelanconium deightonii is assumed to be congeneric with Neomelanconium gelatosporum, and it is lectotypified. Dermatea tetraspora and Phaeangium magnisporum, the basionyms of Mycosphaerangium tetrasporum and M. magnisporum, respectively, are lectotypified as well, and for M. tetrasporum, the asexual morph is recorded for the first time. Mycosphaerangium quercinum sp. nov. is described as a new species from various Quercus hosts in Europe, where it is shown to be widely distributed. It morphologically and ecologically closely resembles the North American M. tetrasporum, but differs in paraphysis and ascospore morphology and by croziers at its ascus base. The three accepted species of Mycosphaerangium and the two of Neomelanconium are described and illustrated. Mycosphaerangium magnisporum, M. quercinum and M. tetrasporum are recorded to be constantly associated with species of Coryneum, indicating a fungicolous habit, but no evidence for fungal associations has been found in Neomelanconium deightonii and N. gelatosporum.

A New Species

A new species, Pleurotheciella nilotica is described and illustrated from the River Nile, Sohag, Egypt. Molecular phylogenetic analyses of the combined SSU and LSU rDNA placed the new species within Pleurotheciella as a phylogenetically distinct species. P. nilotica formed a basal clade to a node containing P. krabiensis and P.tropica. The new species is characterized by its conidial dimensions being smaller than those recorded in the eleven described species of Pleurotheciella.

The aim of this paper is to describe a new species of the genus Loxosceles Heineken & Lowe, 1832 from Morocco, Loxosceles imazighen sp. n., and to describe for the first time a female of Loxoxceles mrazig Ribera & Planas, 2009 from Tunisia. Both species live in xeric and desert environments and are located in southern Atlas Range. Molecular phylogenetic analyses, using mitochondrial (cox1, 16S) and nuclear (H3, 28S) markers, revel that these species are closely related and that they constitute a separate evolutionary lineage of L. rufescens (Dufour, 1820) and of the set of endemic species of the Canary Islands. L. imazighen sp. n. differs from L. mrazig, the closest species morphologically and geographically, in the shapes and proportions of the male palpal tibia and the shapes and dispositions of the female seminal receptacles. In addition, L. mrazig females show morphological variability in their genitalia, mainly in the inner and outer lobes. Although that variability cannot be associated with different populations, since it also appears within individual populations, and is not related to genetic or geographic distances.

African Genus

A new Tunisian species of Acantothereva Séguy is described, reducing several diagnostic characters for this North African genus to interspecific differences among the three included species. An expanded vertex and frons were formerly considered diagnostic for the genus, but the new species, A. oblata, sp. nov., has a vertex lower than the dorsal eye margin and a non-dilated ocellar tubercle. Previously recognized male genitalic characters, however, support the hypothesis that Acantothereva is a monophyletic group. The ability to recognize Acantothereva using external characters is marginally reduced with respect to therevine genera due to the inclusion of the new species, notably relative to Neotherevella Lyneborg. The apparent close phylogenetic relationship among Acantothereva, Acrosathe Irwin & Lyneborg, Irwiniella Lyneborg, and Neotherevella Lyneborg species are discussed herein, based on recent molecular phylogenetic analyses and the morphology of the Tunisian Acantothereva species. A key to the North African therevine genera is included; head and genitalia illustrations and a key to the three Acantothereva species are also presented.

An integrative molecular and morphological study is presented for the family Unidentiidae. Molecular phylogenetic analyses were conducted with the inclusion of all previous and newly obtained molecular data for the family Unidentiidae Millen & Hermosillo 2012. A new species of the genus Unidentia Millen & Hermosillo 2012, U. aliciae sp. nov., is described from Thailand as part of an inventory of sea slugs at Koh Tao. All up-to-date available morphological data for the species of the genus Unidentia is for the first time summarized. Morphological differences among the different species of Unidentia are clarified showing that every species has its own distinguishable morphological traits. According to the new molecular and morphological data, the family Unidentiidae is re-confirmed as a well-supported taxon of the aeolidacean nudibranchs. The taxonomy and phylogeny of the Aeolidacea in the light of the family Unidentiidae is briefly discussed and necessity of a fine-scale and narrowly-defined taxa approach instead of a ‘‘superlumping’’ one is highlighted.

A New Species

Based on molecular evidence and morphological analyses, a new species in the genus Trametopsis is revealed. Trametopsis aborigena sp. nov. is proposed and described from South America. Molecular phylogenetic analyses of ITS and LSU rDNA sequences suggest that Trametopsis cervina seems to encompass more than one species and confirm previous results showing that Antrodiella brasiliensis groups with Trametopsis. The morphological analyses of type specimens of A. brasiliensis and A. luteocontexta revealed a shared morphological pattern with Trametopsis and their combinations in Trametopsis are proposed. The circumscription of Trametopsis is discussed since all the studied specimens revealed a previously overlooked arrangement of characters, i.e., cylindrical and slightly curved to allantoid basidiospores and a metachromatic hyphal system monomitic in the context and dimitic in the tubes.

A New Species

Bredia (Melastomataceae) is an Asian genus that extends from central and southern mainland China to Taiwan and the Ryukyu islands. Molecular phylogenetic analyses reveal that the type of Bredia is nested in a clade of 20 species, while Tashiroea, a genus previously synonymized in Bredia, falls in another distantly related clade of 10 species. Our morphological survey shows that the two clades can be distinguished by several diagnostic features including leaf indumentum, texture, leaf surface sculpture under SEM, presence/absence of yellowish uniseriate trichomes, and capsule morphology. Based on molecular and morphological evidence, Bredia is recircumscribed and Tashiroea is resurrected. Description and a list of species are provided for the two genera with the description of a new species, T.villosa.

Siphocranion is an oligotypic genus of Lamiaceae, with two species mainly distributed in subtropical China and one of them found also in northeastern India, Myanmar, and Vietnam. Based on field investigation, morphological comparison, and molecular phylogenetic analyses, a new species of Siphocranion from the Sino-Vietnamese border is described as S. flavidum. Bayesian and maximum likelihood analyses on two nuclear ribosomal DNA regions and six plastid DNA regions reveal that S. flavidum is a distinct species in the genus and may be sister to the clade formed by the remaining two species of Siphocranion. Morphologically, the new species differs from S. macranthum and S. nudipes in its strigose stem with dark purple spots, thick papery lamina, significantly larger calyx, pale yellow corolla with tube slightly saccate at anterior side of base.

A new species of Lolia and the sexual morph of L. aquatica are described, with illustrations, from decayed submerged wood in the River Nile, Egypt. Molecular phylogenetic analyses of partial SSU and LSU rDNA sequence data place the sexual morph of L. aquatica and the new species, L. dictyospora in a monophyletic clade, distant from the closely related fungi in the freshwater family Lindgomycetaceae. Pairwise LSU rDNA sequence alignment of the sexual/asexual morphs of L. aquatica are 99% similar. Lolia species are characterized by pseudothecial or stromatic, immersed to erumpent, dark-brown to black, coriaceous to sub-carbonaceous ascomata, cylindric-clavate, bitunicate, fissitunicate, short pedicellate asci, yellow to reddish-brown, phragmo- or dictyospores, surrounded by prominent gelatinous sheath. Lolia species are phylogenetically distant from the closely related genera: Leptosphaeria (Leptosphaeriaceae) and Massariosphaeria (Pleosporales incert. sed.). Lolia differs from Leptosphaeria in having a prominent large gelatinous ascospore sheath, while this is absent in Leptosphaeria species. Lolia differs from Massariosphaeria in having smaller ascospores and fewer transverse septa. Based on molecular data and morphology, a new species, Lolia dictyospora, is established.

The Epicopeiidae is a small geometroid family distributed in the East Palaearctic and Oriental regions. It exhibits high morphological diversity in body size and wing shape, while their wing patterns involve in various complex mimicry rings. In the present study, we attempted to describe a new genus, and a new species from Vietnam, with comments on two assumed congeneric novel species from China and India. To address its phylogenetic affinity, we reconstructed the phylogeny of the family by using sequence data of COI, EF-1α, and 28S gene regions obtained from seven genera of Epicopeiidae with Pseudobiston pinratanai as the outgroup. We also compared the morphology of the new taxon to other epicopeiid genera to affirm its taxonomic status. The results suggest that the undescribed taxon deserve a new genus, namely Mimaporia gen. n. The species from Vietnam, Mimaporia hmong sp. n., is described as new to science. Under different tree building strategies, the new genus is the sister group of either Chatamla Moore, 1881 or Parabraxas Leech, 1897. The morphological evidence, which was not included in phylogenetic analyses, however, suggests its potential affinity with Burmeia Minet, 2003. This study also provides the first, although preliminary, molecular phylogeny of the family on which the revised systematics and interpretation of character evolution can be based.

A New Species

Russula subsection Amoeninae is morphologically defined by a dry velvety pileus surface, a complete absence of cystidia with heteromorphous contents in all tissues, and spores without amyloid suprahilar spot. Thirty-four species within subsection Amoeninae have been published worldwide. Although most Russula species in South Korea have been assigned European or North American names, recent molecular studies have shown that Russula species from different continents are not conspecific. Therefore, the present study aims to: 1) define which species of Russula subsection Amoeninae occur on each continent using molecular phylogenetic analyses; 2) revise the taxonomy of Korean Amoeninae. The phylogenetic analyses using the internal transcribed spacer (ITS) and multilocus sequences showed that subsection Amoeninae is monophyletic within subgenus Heterophyllidiae section Heterophyllae. A total of 21 Russula subsection Amoeninae species were confirmed from Asia, Australia, Europe, North America, and Central America, and species from different continents formed separate clades. Three species were recognized from South Korea and were clearly separated from the European and North American species. These species are R. bella, also reported from Japan, a new species described herein, Russula orientipurpurea, and a new species undescribed due to insufficient material.
