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.

Aenigmetopia Malloch is the only endemic genus of miltogrammine flesh flies (Diptera:Sarcophagidae) in Australia and, until now it has been known from a single species, A. fergusoni Malloch. This study constitutes the first comprehensive taxonomic revision of Aenigmetopia. Four new species, Aenigmetopia amissa, sp. nov., A. corona, sp. nov., A. kryptos, sp. nov. and A. pagoni, sp. nov., are described through the integration of molecular and morphological data and characters for genus- and species-level diagnoses are given. Aenigmetopia is included in a molecular phylogenetic analysis for the first time and the genus emerges as the sister taxon to Metopia Meigen, in agreement with morphological evidence.

Palearctic Species

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.

Euphorbia mbuinzauensis, a succulent new species of the Synadenium group in Euphorbiaceae from Makueni County, Kenya, is described and illustrated. Morphologically, it is most similar to E. pseudomollis, but differs mainly by its shrubby habit (up to 4 m), abaxial leaves surfaces with densely stellate hairs, 2–4-forked cymes, smaller bracts (ca. 2.5 × 3.0 mm), smaller cyathia (6 mm wide), crimson glands without narrow smooth margin, smaller fruits (ca. 8 × 7 mm) and ovoid seeds (ca. 1.8 × 2.2 mm). Furthermore, we performed a molecular phylogenetic analysis of the Synadenium group in Euphorbia sect. Monadenium, based on complete nuclear ribosomal DNA (nrDNA) datasets. This phylogenetic inference also supports it to be a distinct species. The new species is assessed as Endangered using the IUCN criteria.

As part of a larger systematic and taxonomic revision, including molecular phylogenetic analysis, of lichenized Basidiomycota in the Dictyonema clade, ten species are described as new from tropical America, seven in the foliose genus Cora and three in the filamentous genus Dictyonema: Cora arachnoidea J. E. Hern. & Lücking, sp. nov., C. aspera Wilk, Lücking & E. Morales, sp. nov., C. byssoidea Lücking & Moncada, sp. nov., C. cyphellifera Dal-Forno, Bungartz & Lücking, sp. nov., C. inversa Lücking & Moncada, sp. nov., C. squamiformis Wilk, Lücking & Yánez-Ayabaca, sp. nov., C. strigosa Lücking, E.

We discuss the taxonomic status of the six names historically established for species belonging in the genus Cora and reinstate the names C. gyrolophia Fr., C. pavonia (Sw.) Fr., and C. reticulifera Vain., providing diagnostic features for these, whereas the status of C. glabrata (Spreng.) Fr. and C. bovei Speg. remains uncertain. The following new combinations are introduced: Cora hirsuta (Moncada & Lücking) Moncada & Lücking, comb. nov., C. minor (Lücking, E. Navarro & Sipman) Lücking, comb. nov., Corella melvinii (Chaves, Lücking & Umaña) Lücking, Dal-Forno & Lawrey, comb. nov., Cyphellostereum phyllogenum (Müll. Arg.)

Keys are presented to the five currently accepted genera and 40 currently recognized species in the genera Cyphellostereum, Dictyonema, Cora, and Corella.

A New Species

Youngia zhengyiana, a new species of Youngia sect. Mesomeris (Asteraceae: Crepidinae) from Guizhou province of south China is described and illustrated. The placement of this species within Youngia is assessed based on a molecular phylogenetic analysis of the nuclear ribosomal ITS and on morphological comparisons with related species. The new species can be easily distinguished by morphology from the only species known to possess 5 florets, Y. szechuanica. The infrageneric classification and the recently debated circumscription of Youngia are discussed in the light of the nrITS phylogeny, which includes several species for the first time. Pseudoyoungia is confirmed as a congener of Youngia. The redefined Youngia is still non-monophyletic with Lapsanastrum nested within it.

Abstract We have undertaken a comprehensive molecular phylogenetic analysis of the Hygrophila based on 3112 sites of the large subunit and 5.8S ribosomal RNA genes. A clear basal division between Chilinoidea and Lymnaeoidea is observed. The monophyly of Acroloxidae, Lymnaeidae and Physidae is also well established. However, Planorbidae are not supported as a monophyletic group, because the Bulinidae cluster within Planorbidae. The Amphipepleinae within Lymnaeidae and both Planorbinae and Ancylinae within Planorbidae are strongly supported as monophyletic subfamilies. However, the Aplexinae within Physidae and the Lymnaeinae within Lymnaeidae are not recovered. A new taxonomic revision of the Hygrophila is proposed based on the findings of this molecular phylogeny, and the implications for the evolution of chirality are discussed.

Genus Two

Names of new taxa, new combinations and names at new rank are proposed for subgenera and sections in Baccharis to move towards a phylogenetic infrageneric classification of this New World genus. Two earlier segregated genera and two previously recognised sections are moved to the subgeneric rank (as B. subgen. Coridifoliae, B. subgen. Heterothalamus, B. subgen. Heterothalamulopsis, and B. subgen. Oblongifoliae). Three new combinations and/or names at new rank are proposed for the following sections: B. sect. Axillares (assigned to B. subgen. Baccharis), B. sect. Heterothalamulopsis (assigned to B. subgen. Heterothalamulopsis), and B. sect. Pluricephalae (assigned to B. subgen Coridifoliae). Four new sections are described to accommodate taxa not corresponding to any previously described section: B. sect. Andina and B. sect. Illinitae (assigned to B. subgen. Baccharis), B. sect. Bradeanae (assigned to B. subgen. Heterothalamus), and B. sect. Polifoliae (assigned to B. subgen. Molina). All taxa here recognized correspond to monophyletic groups based on highly supported clades in a recent molecular phylogenetic analysis.
