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.

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.

One of the major problems hindering the systematic study of tachinid flies is that genera are often poorly defined, making it difficult to unambiguously assign species among closely related genera. Within the tribe Winthemiini, an example of this problem is represented by the unstable classification of the Afrotropical species most recently classified as Smidtia capensis (Schiner). This species has been previously assigned to four different genera on the basis of limited examination and evidence. Here, we evaluate the identity and phylogenetic affinities of this species and other members of the tribe Winthemiini using morphological and molecular phylogenetic analysis. We demonstrate that S. capensis actually belongs to the genus Winthemia Robineau-Desvoidy. We also find that Winthemia is paraphyletic with respect to two monotypic genera, Crypsina (type species Crypsina prima Brauer & Bergenstamm) and Hemiwinthemia (type species Hemiwinthemia calva Villeneuve). On the basis of morphological and genetic evidence, we propose to extend the generic limits of Winthemia to include W. londti, sp. nov. (South Africa), W. capensis (Schiner), comb. nov. (South Africa), W. prima (Brauer & Bergenstamm), comb. nov. (China, Japan, Australia) and W. calva (Villeneuve), comb. nov. (D.R. Congo), thus synonymising with Winthemia the generic names Crypsina, syn. nov. and Hemiwinthemia, syn. nov.

The classification of the genera belonging to the doryctine tribe Rhaconotini (Braconidae) is updated. The following new taxa are described: Troporhaconotus gen. nov. (with 12 species), Afroipodoryctes subgen. nov. (of Ipodoryctes Granger, 1949) (with three species), Hexarhaconotinus subgen. nov. (of Rhaconotinus Hedqvist, 1965) (with ten species), Bathycentor zimbabwensis sp. nov., Ipodoryctes (Afroipodoryctes) reunionus sp. nov., I. (A.) saintphilippensis sp. nov., Platyspathius (Platyspathius) venezuelicus sp. nov., P. (P.) ranomafanus sp. nov., Rhacontsira haeselbarthi sp. nov., Rh. mozambiquensis sp. nov., Rh. saigonensis sp. nov. and Rh. toamasina sp. nov. The generic status of Euryphrymnus Cameron, 1910 is resurrected. The generic name Aptenobracon Marsh, 1965 is synonymised under Rhaconotus Ruthe, 1854 (syn. nov.); Rhaconotus asiaticus Belokobylskij, 1990 is synonymised under Rh. kerzhneri Belokobylskij, 1985 (syn. nov.). The new name, Rhaconotinus austrochinensis nom. nov., is suggested for the preoccupied name Rhaconotus chinensis Chen & Shi, 2004 (December) not Rhaconotus chinensis Belokobylskij & Chen, 2004 (June). New species contents, in many cases with numerous new combinations, are suggested for the genera Bathycentor Saussure, 1892, Euryphrymnus Cameron, 1910, Ipodoryctes Granger, 1949, Rhaconotinus Hedqvist, 1965 and Rhaconotus. The tribe Leptorhaconotini is synonymised with Rhaconotini based on previously published molecular phylogenetic studies, though we leave this group within the subtribe Leptorhaconotina.

Many new combinations are needed in Euploca, previously regarded as Heliotropium section Orthostachys, to correspond with results of our forthcoming, world-wide, molecular phylogenetic analysis. We also need these names for our many δ13C determinations that identify many Euploca species exhibiting C4 photosynthesis and show that other Euploca species are not C4. Here we make the many new combinations required to support these results.

Boletus peckii, B. pulchriceps and B. roseopurpureus, which were originally described from North America, are characterized by a yellow tube layer that often bruises blue, a yellow reticulated stipe especially at the apex, firm yellow-tinged flesh that often turns blue when exposed, smooth spores and an interwoven trichodermic pileipellis. The phylogenetic positions of the three species are inferred by molecular phylogenetic analysis based on DNA sequences of four gene markers (ITS, nrLSU, tef1-α and rpb1). Both morphological features and molecular phylogenetic evidence indicate that these three boletes belong to Butyriboletus, and thus, should be transferred to the genus.

The distinction and monophyletic property of the basidiomycetous yeast species in the Bulleribasidium clade of the order Tremellales was resolved by molecular phylogenetic analysis based on the combined sequences of the 18S rRNA gene, internal transcribed spacer (ITS) region including 5.8S rRNA gene and 26S rRNA gene D1/D2 domain. The addition to the clade of new anamorphic species identified among ballistoconidium-forming yeasts isolated from China confirmed and strengthened the separation of this clade from other clades or lineages in the order Tremellales. A new anamorphic genus, Mingxiaea gen. nov. (type species Mingxiaea variabilis comb. nov.) is therefore proposed to accommodate the anamorphic species in the Bulleribasidium clade. Six new combinations are proposed for the described species of this clade which were formerly assigned to the genus Bullera. Four novel species in the new genus were identified among 16 ballistoconidium-forming yeast strains isolated from plant leaves collected in Hainan province, southern China, by D1/D2 and ITS sequence analyses. The novel species are described as Mingxiaea sanyaensis sp. nov. (type strain SY-3.23T =AS 2. 3623T =CBS 11408T), Mingxiaea hainanensis (type strain WZS-8.13T =AS 2.4161T =CBS 11409T), Mingxiaea foliicola (type strain WZS-8.14T =AS 2.3518T =CBS 11407T) and Mingxiaea wuzhishanensis (type strain WZS-29.8T =AS 2.4163T =CBS 11411T).

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.) Lücking, Dal-Forno & Lawrey, comb. nov., Dictyonema caespitosum (Johow) Lücking, comb. nov., D. irrigatum (Berk. & M. A. Curtis) Lücking, comb. nov., D. phyllophilum (Parmasto) Lücking, Dal-Forno & Lawrey, comb. et stat. nov., and D. scabridum (Vain.) Lücking, comb. et stat. nov. Keys are presented to the five currently accepted genera and 40 currently recognized species in the genera Cyphellostereum, Dictyonema, Cora, and Corella.
