Monadelpha L.J.Gillespie & Card.-McTeag., gen. nov., is described as a new member of Euphorbiaceae tribe Plukenetieae subtribe Tragiinae, to accommodate Tragia guayanensis, a species known from western Amazonas, Venezuela and, newly reported here, from Amazonas, Brazil. The genus is unique in the subtribe for having 5-colpate pollen and staminate flowers with filaments entirely connate into an elongate, cylindrical staminal column terminated by a tight cluster of anthers. Phylogenetic analyses based on nuclear rDNA ITS and sampling 156 accessions across the diversity of Tragiinae (all 12 genera and 77 of ~195 species) also support Monadelpha as a distinct lineage that is separate from Tragia. A revised key to the genera of Tragiinae in South America and Central America is provided.

AbstractItajahya galericulata (Phallales, Phallaceae) was previously reported from several countries in South America and Africa. Recently we found I. galericulata in the city of Vadodara, Gujarat State, India. To verify its identity we studied its morphology and performed molecular phylogenetic analyses using nuclear rDNA LSU and mitochondrial ATP6 loci. Here we also provide nuclear rDNA ITS sequences for the Indian collection, since up to now no sequences of this region have been available for I. galericulata in GenBank. This study furnishes the first evidence for the occurrence of I. galericulata in India and in Asia as a whole.

Amanita submelleialba sp. nov. in section Amanita, is described from northern Thailand based on both multi-gene phylogenetic analysis and morphological evidences. It is characterized by having small to medium-sized basidiomata; a yellow to yellowish pale pileus covering pyramidal to subconical, white to yellow white volval remnants; globose stipe base covered conical, white to yellow white volval remnants; fugacious subapical annulus; and absent clamps. Multi-gene phylogenetic analyses based on partial nuclear rDNA internal transcribed spacer region (ITS), partial nuclear rDNA larger subunit region (nrLSU), RNA polymerase II second largest subunit (RPB2), partial translation elongation factor 1-alpha (TEF1-α) and beta-tubulin gene (TUB) indicated that A. submelleialba clustered together with A. elata and A. mira, but represented as a distinct lineage from other extant species in section Amanita. The detailed morphological characteristics, line-drawing illustration and comparisons with morphologically similar taxa are provided.

External Morphology

The genus Gastrodynerus is here revised based on external morphology and male genitalia. Bohart (1984) proposed Gastrodynerus as a new genus with three species: G. vanduzeei (Bohart 1948), G. searsi Bohart, 1984, and G. stangei Bohart, 1984. Later, Rodriguez-Palafox (1996) added G. tacubayae (de Saussure, 1857). Herein, we describe four new species from Central America and South America: G. guatemalensis sp. nov.; G. barretti sp. nov.; G. aimara sp. nov. and G. yungaensis sp. nov. After this taxonomic revision, the Gastrodynerus includes eight species widely distributed in the New World. An identification key is provided for all of the species.

Based on traditional morphological and phylogenetic analyses (ITS, LSU, tef-1α and β-tub) of psathyrelloid specimens collected from China, four new species are here described: Heteropsathyrella macrocystidia, Psathyrella amygdalinospora, P. piluliformoides, and P. truncatisporoides. H. macrocystidia forms a distinct lineage and groups together with Cystoagaricus, Kauffmania, and Typhrasa in the /Psathyrella s.l. clade, based on the Maximum Likelihood and Bayesian analyses. Thus, the monospecific genus Heteropsathyrella gen. nov. is introduced for the single species. Detailed descriptions, colour photos, and illustrations are presented in this paper.

Internal Transcribed Spacer Sequences

AbstractTo evaluate the phylogenetic relationships of species in Pseudoroegneria and related genera, the nuclear ribosomal internal transcribed spacer (ITS) sequences were analyzed for eighteen Pseudoroegneria (St), two Elytrigia (E e St), two Douglasdeweya (StP), three Lophopyrum (E e and E b), three Agropyron (P), two Hordeum (H), two Australopyrum (W) and two Psathyrostachys (Ns) accessions. The main results were: (i) Pseudoroegneria gracillima, P. stipifolia, P. cognata and P. strigosa (2x) were in one clade, while P. libanotica, P. tauri and P. spicata (2x) were in the other clade, indicating there are the differentiations of St genome among diploid Pseudoroegneria species; (ii) P. geniculata ssp. scythica, P. geniculata ssp. pruinifera, Elytriga caespitosa and Et. caespitosa ssp. nodosa formed the E e St clade with 6-bp indel in ITS1 regions; and (iii) Douglasdeweya wangii, D. deweyi, Agropyron cristatum and A. puberulum comprised the P clade. It is unreasonable to treat P. geniculata ssp. scythica and P. geniculata ssp. pruinifera as the subspecies of P. geniculata, and they should be transferred to a new genus Trichopyrum, which consists of species with E e St genomes. It is also suggested that one of the diploid donor of D. wangii and D. deweyi is derived from Agropyron species, and it is reasonable to treat tetraploid species with StP genomes into Douglasdeweya.

SUMMARYWe propose a taxonomic revision of the dixenous trypanosomatids currently classified as Endotrypanum and Leishmania, including parasites that do not fall within the subgenera L. (Leishmania) and L. (Viannia) related to human leishmaniasis or L. (Sauroleishmania) formed by leishmanias of lizards: L. colombiensis, L. equatorensis, L. herreri, L. hertigi, L. deanei, L. enriettii and L. martiniquensis. The comparison of these species with newly characterized isolates from sloths, porcupines and phlebotomines from central and South America unveiled new genera and subgenera supported by past (RNA PolII gene) and present (V7V8 SSU rRNA, Hsp70 and gGAPDH) phylogenetic analyses of the organisms. The genus Endotrypanum is restricted to Central and South America, comprising isolates from sloths and transmitted by phlebotomines that sporadically infect humans. This genus is the closest to the new genus Porcisia proposed to accommodate the Neotropical porcupine parasites originally described as L. hertigi and L. deanei. A new subgenus Leishmania (Mundinia) is created for the L. enriettii complex that includes L. martiniquensis. The new genus Zelonia harbours trypanosomatids from Neotropical hemipterans placed at the edge of the Leishmania–Endotrypanum-Porcisia clade. Finally, attention is drawn to the status of L. siamensis and L. australiensis as nomem nudums.

Distinct Lineage

A new ascomycete species, inhabiting decaying bamboo culms, is introduced in this paper based on morphology and molecular evidence. Analyses of partial LSU sequence data place the taxon in a monophyletic clade within the order Pleosporales. Morphological characters of the taxon are also distinct from other members of Pleosporales. Ligninsphaeria jonesii gen. et sp. nov. is therefore introduced to accommodate the new taxon, which is characterized by its clypeate, scattered, deeply immersed ascomata, with a slit-like opening, long ostioles, cellular pseudoparaphyses, clavate asci containing broad-fusiform and 1-septate ascospores surrounded by a gelatinous cap at both ends. The phylogenetic analyses show that the new taxon is phylogenetically close but distinct from the families Amniculicolaceae and Testudinaceae, and forms a distinct clade from other taxa in Pleosporales. The new taxon is described and compared with similar taxa. A new genus Ligninsphaeria (Pleosporales, incertae sedis) is introduced to accommodate this distinct lineage.

Devilleferus brunkei Jenkins Shaw & Solodovnikov, gen. et sp. nov., a distinctive new genus and species of Staphylinini rove beetle with an unusual set of morphological characters is described from the tropical Andes (Ecuador and possibly Colombia and Bolivia) in South America. To resolve systematic placement of the new genus within Staphylinini we assembled a dataset of 68 morphological characters scored for 34 taxa representing a broad sample of the respective rove beetle tribe, and performed Bayesian inference and maximum parsimony phylogenetic analyses. Both analytical methods unambiguously placed Devilleferus as sister to the subtribe Amblyopinina, and overall they corroborated recently established subtribal systematics for Staphylinini inferred mainly from molecular markers. Based on the shared synapomorphies, Devilleferus is assigned to the subtribe Amblyopinina. The internal relationships within Amblyopinina remain to be clarified in a broader study of that very poorly explored austral lineage.

The myrtle rust Puccinia psidii originates from South America but is nowadays a very important and invasive pathogen on several genera of Myrtaceae outside of its native area, and especially in Australia, a biodiversity hotspot of Myrtaceae. To date, the taxonomic position of P. psidii has been unclear. The present phylogenetic analyses as well as several former studies show that it does not belong to the genus Puccinia and appears outside of the family Pucciniales. It is, however, closely related to the genera Dasyspora, Puccorchidium, Sphenorchidium and Sphaerophragmium. Consequently, the new genus Austropuccinia has been erected and placed in the newly circumscribed family Sphaerophragmiaceae.
