Four species, including one newly described, of Japanese cleistocarpous species of Weissia (Pottiaceae): W. exserta, W. japonica, W. kiiensis and W. parajaponica sp. nov. are recognized based on molecular phylogenetic inference and morphological reassessment. For each species, typification, description, distribution, illustrations and photographs are presented, and a key to the species is included. Rapid sporophyte modifications in Weissia and monophyletic positions of these four species are supported by the analysis using concatenated chloroplast rbcL and rps4 gene sequences. A lectotype is designated for W. controversa which is the type species of the genus, and a new combination, W. loncophylla is proposed for Trachycarpidium lonchophyllum.

Among New World direct-developing frogs belonging to the clade Brachycephaloidea (= Terraranae), there are several genera with uncertain phylogenetic placements. One notable example is the genus Niceforonia Goin & Cochran 1963, which includes three species that are endemic to Colombia. Three specimens of the species Niceforonia nana were collected and for the first time the genus is included in a molecular phylogenetic analysis of mitochondrial (mtDNA; 12S and 16S) and nuclear (nucDNA; TYR and RAG1) markers. Molecular phylogenetic inference based on concatenated and separate mtDNA and nucDNA analyses recovered Niceforonia nana nested within Hypodactylus Hedges et al. 2008, rendering the latter genus paraphyletic. Consequently, herein we place the genus Hypodactylus in the synonymy of Niceforonia to resolve the paraphyly and place Niceforonia in the subfamily Hypodactylinae. Based on our revised concept of the genus Niceforonia we conducted preliminary morphological comparisons using specimens and literature descriptions. Finally, Nicefornia nana is quite divergent from other species of Niceforonia (uncorrected genetic distances of ca. 10% 16S and 7% TYR) suggesting that further taxonomic revision may be warranted.

Based on the results of morphological and molecular phylogenetic analyses of newly collected material, we reinstate thesoft coral genus Eunephthya Verrill, 1869 for a group of species endemic to South Africa. Eunephthya is morphologicallyand phylogenetically distinct from the zooxanthellate, tropical genus Capnella Gray, 1869 with which it had been synon-ymized. In Eunephthya the polyp sclerites include unilaterally spinose or leaf spindles, and the sclerites of the stalk surfaceand interior (when present) are small radiates and spheroids. In contrast, C. imbricata, the type species of Capnella, hasleaf clubs and leaf-capstans in the polyps and stalk surface, and large ovals and irregular forms in the interior. We describefour new species of Eunephthya from Algoa Bay, South Africa—E. celata, E. ericius, E. granulata, and E. shirleyae— and propose a new combination, E. susanae.Keywords.

The genus Asteralobia (Diptera, Cecidomyiidae, Asphondyliini, Schizomyiina) was erected by Kovalev (1964) based on the presence of constrictions on the cylindrical male flagellomeres. In the present study, we examine the morphological features of Asteralobia and Schizomyia and found that the male flagellomeres are constricted also in Schizomyiagaliorum, the type species of Schizomyia. Because no further characters clearly separating Asteralobia from Schizomyia were observed, we synonymize Asteralobia under Schizomyia. Molecular phylogenetic analysis strongly supports our taxonomic treatment. We describe five new species of Schizomyia from Japan, S.achyranthesae Elsayed & Tokuda, sp. n., S.diplocyclosae Elsayed & Tokuda, sp. n., S.castanopsisae Elsayed & Tokuda, sp. n., S.usubai Elsayed & Tokuda, sp. n., and S.paederiae Elsayed & Tokuda, sp. n., and redescribe three species, S.galiorum Kieffer, S.patriniae Shinji, and S.asteris Kovalev. A taxonomic key to the Japanese Schizomyia species is provided.

The snow hebes, formerly comprising the genus Chionohebe, are here included within Veronica (Plantaginaceae). The five species (including two subspecies) of snow hebes recognised here are cushions or subshrubs that occur exclusively in high-elevation habitats of Australia and the South Island of New Zealand. Species delimitation among the cushion snow hebes is very difficult because of the reduced pulvinate habit, solitary flowers and few gross-morphological characters useful for identification. To address species limits, investigate intraspecific patterns and revise the taxonomy of the snow hebes, morphological analyses were conducted and the results compared with previously published molecular phylogenetic data. Ordination and clustering analyses of morphological data showed some taxonomic structuring; however, species clusters were not widely separated from one another. Morphological and amplified fragment length polymorphism (AFLP) data show that the cushion species are clearly distinguished from the subshrub species, V. densifolia (F.Muell.) F.Muell. Among the four cushion species (V. chionohebe Garn.-Jones, V. ciliolata (Hook.f.) Cheeseman, V. pulvinaris (Hook.f.) Cheeseman, V. thomsonii (Buchanan) Cheeseman), the distribution of leaf trichomes is important for species identification, particularly when used in conjunction with ovary vestiture, capsule size, and/or seed size. One new combination V. ciliolata subsp. fiordensis (Ashwin) Meudt is proposed, and V. uniflora Kirk is treated as a naturally occurring hybrid V. × uniflora (V. densifolia × V. thomsonii). Complete synonymies, descriptions, illustrations and range maps are provided for each species, as well as a key to all species and a discussion of putative hybrids.

The African genus Bocatella Villiers, 1948 is revised. The type species of Bocatella by original designation is Harpactor nigripennis (non Fairmaire, 1858): Villiers, 1948 (misidentification). A lectotype is designated for H. nigripennis and the new combination Sphedanolestes nigripennis (Fairmaire, 1858), comb.n. is proposed. The taxonomic species Harpactor nigripennis (non Fairmaire, 1858): Villiers, 1948 is recognized as representing an undescribed species and is described as Bocatella nigra sp.n. Since the type species of Bocatella was misidentified, B. nigra sp.n. is fixed as the type species of Bocatella. An additional new species, B. femorata sp.n. is described, both species and S. nigripennis are illustrated, species of Bocatella are keyed. Sphedanolestes fenestriculatus Karsch, 1892, erroneously synonymized with H. nigripennis (non Fairmaire, 1858): Villiers, 1948 by Villiers (1948) is synonymized with H. nigripennis Fairmaire, 1858.

In his monograph on Mesozoic-Cenozoic Larger Benthic Foraminifera from the area of Middle East and south-western Asia, Henson (1948) erected the genus Dictyconella for more or less "compressed-conical" dictyoconids including D. complanata (type-species) and D. minima. Both are however, structurally completely different, e.g. aligned (in the latter) versus alternating structural elements (in the former), and cannot either belong to the same genus or the same subfamily (Dictyoconinae versus Dictyorbitolininae). Therefore, the new genus Gusicella is erected with the type-species Dictyoconella minima, resulting in the new combination Gusicella minima. Gusicella represents the only taxon of the Dictyorbitolininae in the Upper Cretaceous Global Community Maturation Cycle of Larger Benthic Foraminifera (here: conical agglutinated). Due to the revision, Dictyoconella is described as a monospecific genus and an assumed Maastrichtian newcomer which, like Gusicella, became extinct shortly afterwards, namely at the K-Pg boundary mass-extinction event. Both taxa appear to be restricted to the former Arabian Plate of the southern Neotethyan margin. The new data provided are based on material from the Maastrichtian Tarbur Formation of southwestern Iran (Zagros Zone).

Calvez (1989) described a new orbitolinid as Aragonella marginata n. gen., n. sp. from the Albian of Spain. The genus name however is a junior homonym of Hantkenina (Aragonella) Thalmann, 1942, an Eocene foraminiferal genus. In accordance with Article 60.3 of the International Code of Zoological Nomenclature (ICZN), the new replacement name Calvezella is introduced for Aragonella Calvez, 1989. This taxonomic revision leads to the new combination Calvezella aragonata (Calvez, 1987) for its only species.

Triblidiaceae (Rhytismatales) currently consists of two genera: Triblidium and Huangshania. Triblidium is the type genus and is characterised by melanized apothecia that occur scattered or in small clusters on the substratum, cleistohymenial (opening in the mesohymenial phase), inamyloid thin-walled asci and hyaline muriform ascospores. Before this study, only the type species, Triblidium caliciiforme, had DNA sequences in the NCBI GenBank. In this study, six specimens of Triblidium were collected from China and France and new ITS, mtSSU, LSU and RPB2 sequences were generated. Our molecular phylogenetic analysis and morphological study demonstrated three new species of Triblidium, which are formally described here: T. hubeiense, T. rostriforme and T. yunnanense. Additionally, our results indicated that Huangshania that was considered to be distinct from Triblidium because of its elongated, transversely-septate ascospores, is congeneric with Triblidium. Therefore, we have placed Huangshania in synonymy under Triblidium, rendering Triblidiaceae a monotypic family.

All taxa of the newly established genus Pseudocodon (= Codonopsis subg. Pseudocodonopsis), except for Pseudocodon rosulatus, form a complicated group extremely controversial on species delimitation. In the present study, numerous field trips were made, 29 populations were observed, and over 800 specimens of the genus preserved in 18 herbaria were critically examined. Statistical analysis of the characters was carried out based on 148 samples from specimens and 16 field populations. Four fragments of chloroplast DNA (atpB, matK, rbcL, petD with petB-petD spacer) and ITS of nuclear DNA were used in the molecular phylogenetic analysis of 40 samples from specimens and 22 field populations. A taxonomic revision of the genus Pseudocodon is presented on the basis of these studies. We recognize eight species: Pseudocodon convolvulaceus, Pse. graminifolius, Pse. grey-wilsonii, Pse. hirsutus, Pse. petiolatus, Pse. retroserratus, Pse. rosulatus, and Pse. vinciflorus. In the present study, one new species and one new subspecies are described, and one new combination is made. In addition, nine taxa are treated as synonyms, and six lectotypes are designated.
