A new black fly species of the subgenus Asiosimulium Takaoka & Choochote of the genus Simulium was recognized from northeastern Thailand based on morphology, mitochondrial DNA and ecology. This black fly species has similar morphological characteristics to Simulium oblongum Takaoka and Choochote that was also described from the same geographic region in all life stages. However, this new species could be distinguished at the adult stage by coloration of the maxillary palp and in the larval stage by the presence of a pigmented subesophageal ganglion that is lacking in S. oblongum. Genetic distance and phylogenetic analyses based on mitochondrial cytochrome c oxidase I sequences clearly differentiated the two species with minimum genetic distance of 3.51%. These species are also ecologically isolated as S. oblongum is found only at low elevation (<650 m above sea level) but the new species occurs only at high elevation (>1,100 m above sea level).

A new black fly species of the Simulium multistriatum species-group of the subgenus Simulium Latreille is described from the mountainous area in northeastern Thailand, based on morphology and mitochondrial DNA sequences. The new species is morphologically similar to S. laui Takaoka and Sofian-Azirun and S. lacduongense Takaoka and Ya’cob originally described from Vietnam, S. fenestratum Edwards originally described from Indonesia and S. chaliowae Takaoka and Boonkemtong originally described from Thailand, but can be distinguished in the adult stage by the number of upper eye facets and globular shape of the spermatheca and in the pupal stage by the cocoon and shape of thoracic tubercles. Genetic distance and phylogenetic analyses of mitochondrial cytochrome c oxidase I sequences differentiated the new species from other members of S. multistriatum species-group. All specimens of the new species formed a monophyletic clade with strong support in all phylogenetic analyses. The minimum interspecific genetic distance of 4.9% is considerably greater than the new species maximum intraspecific genetic distance (2.7%).

New species of Undifilum , from locoweeds Astragalus lentiginosus Vitman and Astragalus mollissimus Torr., are described using morphological characteristics and molecular phylogenetic analyses as Undifilum fulvum Baucom & Creamer sp. nov. and Undifilum cinereum Baucom & Creamer sp. nov. Fungi were isolated from dried plants of A. lentiginosus var. araneosus , diphysus , lentiginosus , and wahweapensis collected from Arizona, Oregon, and Utah, USA, and A. mollissimus var. biglovii , earleii , and mollissimus collected from New Mexico, Oklahoma, and Texas, USA. Endophytic fungi from Astragalus locoweeds were compared to Undifilum oxytropis isolates obtained from dried plant material of Oxytropis lamberteii from New Mexico and Oxytropis sericea from Arizona, Colorado, New Mexico, Utah, and Wyoming. Extremely slow growth in vitro was observed for all, and conidia, if present, were ellipsoid with transverse septa. However, in vitro color, growth on four different media, and conidium size differed between fungi from Astragalus spp. and U. oxytropis. Neighbor-joining analyses of internal transcribed spacer (ITS) region and glyceraldehyde-3-phosphate dehydrogenase (GPD) gene sequences revealed that U. fulvum and U. cinereum formed a clade distinct from U. oxytropis. This was supported by neighbor-joining analyses of results generated from random amplified polymorphic DNA (RAPD) fragments using two different primers.

Species in the genus Tomentella are distributed throughout the temperate and tropical regions worldwide, but few studies associated with the taxonomy and phylogeny of this genus had been reported from Northwest China. In this paper, molecular phylogenetic analyses of the nuclear ribosomal ITS (internal transcribed spacer: ITS1-5.8S-ITS2) and LSU (large subunit: 28S) sequences combined with morphological characteristics identified three new species from Xinjiang Autonomous Region in Northwest China, which were named T. aurantispora, T. kanasensis, and T. schrenkiana. Similar macromorphological and anatomical characteristics are shared by these new species: arachnoid basidiocarps; byssoid sterile margins; utriform basidia with a clamp connection at the base; the absence of rhizomorphs and cystidia; and slightly thick-walled, subglobose to globose basidiospores. Among these new species, the color of the hymenophoral surface, the size of the basidiospores, and some other features can be used for species delimitation. The new species and closely related species in the phylogenetic tree were discussed, and a key to the identified species of Tomentella from China was provided.

Grammatuslabyrinthinusgen. et sp. nov. is proposed based on DNA sequences data and morphological characteristics. It is known so far from southern, tropical China. The new species is characterised by an annual, resupinate basidiocarp with a shallow, subporoid hymenophore, a hymenium restricted to the bottom of the tubes, a dimitic hyphal system, presence of encrusted skeletocystidia and dendrohyphidia, longitudinally septate basidia and smooth, oblong-ellipsoid to cylindrical, acyanophilous basidiospores. Phylogenetic analyses based on ITS + nLSU DNA sequences data indicate that G.labyrinthinus belongs to Auriculariaceae in which it has an isolated position. Phylogenetic inferences show G.labyrinthinus to be related to Heteroradulum. However, the ITS sequences similarity between G.labyrinthinus and H.kmetii, the type species of Heteroradulum, were 89.84% and support the establishment of the new genus. Inversely, Heteroradulumsemis clustered with G.labyrinthinus with strong support and it is transferred to Grammatus.

Lower Molar

During a faunal survey in southern Xizang, we collected 27 specimens of voles that could not be identified as any knownspecies in the Arvicolinae. These specimens shared the following morphological characteristics, not corresponding withany other arvicoline species: the first lower molar possessed five closed triangles, the third upper molar exhibited eitherfour or three inner angles, and the tails of all specimens measured 30% of the body length. Their proximal baculum of theglans was very sturdy and trumpet-shaped, the distal baculum was tongue-like and sturdy, and the lateral bacula were veryshort. Molecular phylogenetic analyses based on nucleotide sequences of the mitochondrial cytochrome b (cyt b) geneclustered these specimens as a distinct lineage within the genus Neodon. According to the morphological and moleculardata, we described them as a new species, Neodon linzhiensis. Our phylogenetic analysis strongly supported that Lasio-podomys fuscus, Phaiomys leucurus, Neodon sikimensis, N. irene and the new species formed a monophyletic group, notincluding N. juldaschi. We suggested that L. fuscus and P. leucurus should be transferred to Neodon and that N. juldaschishould be removed from this genus. Following our new delineation of Neodon, we proposed a redefinition of the morphological diagnostic characters of the genus.

Taxonomic System

Agaricus is a species-rich genus with more than 500 species over the world. Recent studies on tropical Agaricus revealed new tropical clades and a revised taxonomic system was consequently developed. Agaricus subg. Minoriopsis, a sixth subgenus was recently added, comprising species exclusively from the Americas. The diversity of Agaricus is little studied in Mexico, despite this country has a long history in the consumption of wild edible fungi. In this paper, we introduce a new species A. guzmanii and a new record for A. globocystidiatus from Mexico based on morphological characteristics and molecular data. Phylogenetic analyses indicate that they belong to A. subg. Minoriopsis.

Iochroma amicorum M. Cueva, S. D. Sm. & S. Leiva (Solanaceae), a new species from cloud forests of Central Peru, is described and illustrated. Phylogenetic analyses of DNA sequence data suggest that Iochroma amicorum is closely related to I. nitidum, I. umbellatum, I. grandiflorum and I. tingoanum, which collectively form the “U” clade of Iochrominae. Certain morphological characteristics of calyx and corolla as well as the type of habitat appear to be common in species of this clade. Iochroma amicorum is easily distinguished from other members of the “U” clade by its campanulate or funnel-shaped corolla with short and slightly reflexed lobes, the presence of an expanded stapet at the point of filament insertion with short lateral extensions united to the corolla, and its globose usually white fruits with tinges of purple at the base. Distribution, phenology and are discussed together with the position of the new species in Iochrominae. Iochroma amicorum is assessed as Endangered according to IUCN criteria B1ab (i, iii)

Andeimalvaperuviana Dorr &amp; C.Romero, sp. nov., the third Peruvian endemic in a small genus of five species, is described and illustrated from a single collection made at high elevation on the eastern slopes of the Andes. Molecular phylogenetic analyses of nuclear ribosomal ITS sequence data resolve a group of northern species of Andeimalva found in Bolivia and Peru from the morphologically very different southern A.chilensis. The new species bears the largest flowers of any Andeimalva and is compared with Bolivian A.mandonii. A revised key to the genus is presented.
