Distinct Genus

The diversity of Panophrys horned toads is considered highly underestimated with a large number of undescribed cryptic species. In this work, we describe four Panophrys species from eastern China which were proposed as cryptic species by molecular data in previous study, additionally provide new information on the biogeography of these four species. Panophrys daiyunensis sp. nov. from southern Fujian, Panophrys daoji sp. nov. from eastern Zhejiang, Panophrys sanmingensis sp. nov. from the hilly area among Fujian, Jiangxi and Guangdong, and Panophrys tongboensis sp. nov. from northeastern Jiangxi, can be distinguished from all recognized congeners by a combination of morphological characteristics. The descriptions of these four new species take the recognized species of Panophrys to 51, which is the largest genus within the Asian horned toads subfamily Megophryinae. Considered as an appropriate arrangement for the Asian horned toads currently and applied in this study to describe the new species, the generic recognition of Panophrys is also discussed.

SUMMARYRecent studies have shown that some digenean trematodes previously identified as single species due to the lack of distinguishing morphological characteristics actually consist of a number of genetically distinct cryptic species. We obtained mitochondrial 16S and nuclear ITS1 sequences for the redial stages of Acanthoparyphium sp. and Curtuteria australis collected from snails and whelks at various locations around Otago Peninsula, New Zealand. These two echinostomes are well-known host manipulators whose impact extends to the entire intertidal community. Using phylogenetic analyses, we found that Acanthoparyphium sp. is actually composed of at least 4 genetically distinct species, and that a cryptic species of Curtuteria occurs in addition to C. australis. Molecular data obtained for metacercariae dissected from cockle second intermediate hosts matched sequences obtained for Acanthoparyphium sp. A and C. australis rediae, respectively, but no other species. The various cryptic species of both Acanthoparyphium and Curtuteria also showed an extremely localized pattern of distribution: some species were either absent or very rare in Otago Harbour, but reached far higher prevalence in nearby sheltered inlets. This small-scale spatial segregation is unexpected as shorebird definitive hosts can disperse trematode eggs across wide geographical areas, which should result in a homogeneous mixing of the species on small geographical scales. Possible explanations for this spatial segregation of the species include sampling artefacts, local adaptation by first intermediate hosts, environmental conditions, and site fidelity of the definitive hosts.

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.

A New Species

The identification of Auricularia species has previously relied on the examination of macroscopic features of mushroom samples collected in Thailand. These features may vary with age, light exposure, moisture and other factors, making such identification prone to error. This study uses morphological characteristics and molecular data to improve upon previous classifications of Auricularia species. Fruiting bodies collected during recent field excursions and previous collections from herbaria were examined and sequenced for two loci, viz. ITS and rpb2. Auricularia asiatica is described as a new species based on both morphological characteristics and molecular data, and is introduced with a full description, illustrations and colour photographs. Auricularia cornea and A. villosula are described as new records from Thailand. A combined ITS and rpb2 phylogenetic tree is provided, showing the placement of five Auricularia species found in Thailand.

A New Species

A phylogeny of all nine subgenera of Drosanthemum, based on chloroplast sequence-data, is presented. The results confirm some previously published facts, e.g. that D. zygophylloides is sister to Drosanthemum. We propose to treat this species as a new monotypic genus, Lemonanthemum, which differs from Drosanthemum in features of the leaves and fruit-stalks. In Drosanthemum s.s., the small subg. Quadrata, characterized by 4-locular fruits, is highly supported as sister to the remainder of Drosanthemum (where fruits are 5-locular). Further, our data support the transfer of Delosperma pubipetalum to Drosanthemum (where a nomenclatural change is also made). The pubescent petals, 5-locular fruits with narrow covering membranes and downward-pointing hair-like papillae on the branches suggest that D. pubipetalum is close to D. papillatum and belongs to subg. Quastea. Another species, D. badspoortense, which had been placed in D. subg. Quastea on account of its narrow covering membranes, is shown to belong to Delosperma and also lacks the unique structure of the fruit-stalk of Drosanthemum. In addition, a new species, D. overbergense, is described from disjunct patches of remnant renosterveld within the Overberg and near Albertinia, in the Western Cape of South Africa. Morphological characteristics suggest that this species belongs to subg. Xamera, but this was not corroborated by our molecular data. Finally, a new name—Drosanthemum calcareum—is proposed for the illegitimate D. intermedium and a lectotype (at BOL) is designated for D. pubipetalum. The lectotypification of D. badspoortense is also proposed.

In this paper, a new spider species of the genus Loxosceles is described on the basis of morphological and molecular data. The phylogenetic relationship of the new species is discussed through the lens of molecular data (cox1, rrnL and H3 genes). Specimens were collected from three Iranian caves in the provinces of Fars, Yazd and Khuzestan, and the specimens showed morphological characteristics that allowed us to easily distinguish Loxosceles persica n. sp. from L. mrazig, which is its sister species, and from the cosmopolitan L. rufescens, which is a widely distributed species throughout the Mediterranean basin and the Middle East. It is the first Loxosceles species endemic to the Middle East.

Samples of species close to Tremella fibulifera from China and Brazil are studied, and T. fibulifera is confirmed as a species complex including nine species. Five known species (T. cheejenii, T. fibulifera s.s., T. “neofibulifera”, T. lloydiae-candidae and T. olens) and four new species (T. australe, T. guangxiensis, T. latispora and T. subfibulifera) in the complex are recognized based on morphological characteristics, molecular evidence, and geographic distribution. Sequences of eight species of the complex were included in the phylogenetic analyses because T. olens lacks molecular data. The phylogenetic analyses were performed by a combined sequence dataset of the internal transcribed spacer (ITS) and the partial nuclear large subunit rDNA (nLSU), and a combined sequence dataset of the ITS, partial nLSU, the small subunit mitochondrial rRNA gene (mtSSU), the translation elongation factor 1-α (TEF1), the largest and second largest subunits of RNA polymerase II (RPB1 and RPB2). The eight species formed eight independent lineages with robust support in phylogenies based on both datasets. Illustrated description of the six species including Tremella fibulifera s.s., T. “neofibulifera” and four new species, and discussions with their related species, are provided. A table of the comparison of the important characteristics of nine species in the T. fibulifera complex and a key to the whitish species in Tremella s.s. are provided.

Three new cryptic species ofChiasmocleisfrom the Atlantic Forest of Brazil are described. Two of these species occur in the northeastern states of Sergipe and Bahia, whereas the third species is found in the southeastern state of São Paulo. The new species can be distinguished from other congeneric species by the molecular data, as evidenced in the phylogeny, and by a combination of morphological characters including: size, foot webbing, dermal spines, and coloration patterns.Chiasmocleisspecies differ in osteological traits, therefore we also provide an osteological description of each new species and comparsions with data reported for other species in the genus.

Mtdna Genealogy

Recent phylogenetic analysis encompassing multilocus nuclear-gene and matrilineal mtDNA genealogy has revealed a series of cryptic species of the subgenus Panophrys within genus Megophrys from southern and eastern China. This study demonstrates that the Panophrys specimens from the hilly areas among Guangdong, Guangxi and Hunan can be morphologically distinguished from all recognized congeners, thereby providing additional supports for the recognitions of four new species of Panophrys, namely Megophrys (Panophrys) mirabilis Lyu, Wang & Zhao, sp. nov. from northeastern Guangxi, Megophrys (Panophrys) shimentaina Lyu, Liu & Wang, sp. nov. from northern Guangdong, and Megophrys (Panophrys) xiangnanensis Lyu, Zeng & Wang, sp. nov. and Megophrys (Panophrys) yangmingensis Lyu, Zeng & Wang, sp. nov. from southern Hunan. The descriptions of these species take the number of Megophrys species to 101, 46 of which belong to the subgenus Panophrys.

Nidirana guangxiensissp. nov., a new music frog species, is proposed, based on a series of specimens collected from Mt Daming, Guangxi, southern China. The new species is close to N. yeae, N. daunchina, N. yaoica, and N. chapaensis from southwestern and south-central China and northern Indochina, while the relationships among these species remain unresolved. Nidirana guangxiensis sp. nov. can be distinguished from all known congeners by the genetic divergences in the mitochondrial 16S and COI genes, the behavior of nest construction, the advertisement call containing 6–11 rapidly repeated regular notes, and a combination of morphological characteristics. Furthermore, the Nidirana populations recorded in Guangxi are clarified in this work, providing valuable new information on the knowledge of the genus Nidirana.

A New Species

In this study, we describe a new species of salamander, Paramesotriton maolanensis sp. n., from the MaolanNational Nature Reserve, Libo County, Guizhou Province, China. The new species is placed in the genusParamesotriton based on morphological characteristics and molecular data. It differs from all other members of thegenus in a number of morphological characteristics, especially in its much larger body size, absence of granularwarts from head and body, largely reduced external eyes and peculiar shape of epibranchia in hyoid apparatus. Weexamined the relationships of nuclear POMC haplotypes between and within the new species and six recognizedspecies. POMC variation and published mitochondrial data suggested that the new species’ closest known relativesare P. longliensis, P. zhijinensis and P. caudopunctatus, and it should be placed into the P. caudopunctatus species group or subgenus Allomesotriton.
