A New Species

The genus Minuartia is represented in Turkey by 34 taxa. Some interesting specimens were collected from Antalya province, and examined. These specimens resemble Minuartia meyeri, and M. multinervis from which differ by characters (macro-, and micromorphological) of inflorescence, alar pedicels, petals, sepals, capsules and seeds. Moreover, by using the DNA sequences of the ITS genes, phylogenetic relationships between this collected species, and the related species were investigated. As a result of the evaluation of molecular, and morphological data, we proposed to described the population from Antalya as a new species for the science. A description, pictures, distribution, habitat, and IUCN category are given.

Russula subrutilans sp. nov., a new species of Russula is described from southern China. It is unique for having buff pink to light congo-pink pileus, distant ventricose to subventricose lamellae with rare lamellulae, globose to broadly ellipsoid spores with bluntly conical warts forming a partial reticulum, and narrowly clavate to clavate cheilocystidia and pleurocysitidia with variable tips. Phylogenetic relationships among the new species and other closely related species in the genus are inferred based on the internal transcribed spacer (ITS) region.

A New Species

A new species, Strobilomyces rubrobrunneus, is described from eastern China based on morphological and molecular evidence. Morphologically, this species is characterized by its tiny to small basidiomes, reddish-brown and more or less erect pyramidal scales, grayish black discoloration of the pileal context when bruised, reticulate spores and a subtropical distribution in a mixed forest of Fagaceae and Pinaceae. Our phylogenetic analyses based on four gene markers (rpb1, rpb2, tef1 and cox3) support its placement in Strobilomyces and its separation from other related species of this genus. Morphological illustrations and description are provided.

ABSTRACT The sciaenid genus Bairdiella comprises a group of relatively small fishes found in inshore waters and estuaries of the western Atlantic and eastern Pacific. Despite recent analyses of the phylogenetic relationships of Bairdiella, there has been no comprehensive revision of the alpha taxonomy of the species of the genus. Bairdiella ronchus from the western Atlantic, has a complex taxonomic history, with four junior synonyms recognized. Based on morphological and molecular evidence, this study indicates that B. ronchus represents a species complex. The species is therefore redescribed and its geographic range is redefined. Bairdiella veraecrucis, which is currently recognized as a junior synonym of B. ronchus, is revalidated, and a new species of the genus is described from the Atlantic coast of Brazil. Finally, inferences are made on the diversity and biogeography of the B. ronchus species complex.

Petrocodon asterocalyx F.Wen, Y.G.Wei & R.L.Zhang, a new species from the Danxia landform area in Guangxi, South China, is described and illustrated based on molecular and morphological data. The molecular evidence shows that the new species is recovered in a weakly supported clade. Within this clade, the new one is morphologically similar to P. hancei (Hemsl.) A.Weber & Mich.Möller and P. coriaceifolius (Y.G.Wei) Y.G.Wei & Mich.Möller, and it can be distinguished from the former by calyx lobes 20–40 × 2–3 mm, corolla 2.5–3.0 cm long, filaments sparsely erectly pubescent, anthers sparsely pubescent, staminodes 3, and stigmas 2; from latter by leaf blades rhombic-oblong or rhombic, base shallowly cuneate, margin crenulate to serrate, calyx lobes linear, 20–40 × 2–3 cm, and anthers 3.5–3.8 mm long, sparsely pubescent and elliptical.

Abstract Aegla lata Bond-Buckup & Buckup, 1994 is considered extinct in the type locality. New populations of this species, however, have been found in northern Paraná state, Brazil. We revised the taxonomy of A. lata based on morphological data obtained from the type material and specimens recently obtained from streams of the Tibagi River sub-basin, Paranapanema River basin, Upper Paraná Ecoregion. Moreover, Aegla jacutingan. sp. is described and illustrated. The new species resembles A. lata in the shapes of the body and chelipeds. Both species are nevertheless separated by particular morphological characters of the carapace, chelipeds, and epimeron as well as by molecular (COI mtDNA) differences. Both species can be distinguished from their congeners based on morphological and molecular evidence.

A New Species

Specimens from southeastern and southern Brazil previously identified as Sheathia arcuata (= Batrachospermum arcuatum) are shown to be members of the recently described genus Nocturama, previously known only from Australia and New Zealand. Morphological and molecular evidence support recognizing the Brazilian specimens as a new species, described here as Nocturama novamundensis, sp. nov. Comparison of DNA sequences of the plastid-encoded ribulose-1,5-bisphosphatecarboxylase–oxygenase large subunit (rbcL) and the nuclear small subunit ribosomal DNA (SSU rDNA) markers showed Nocturama as a well supported clade. The sequence divergences between the new and the type species were high (95-98bp, 7.4–7.6%) for rbcL and 19bp, 1.1% for SSU), and those within each species were extremely low (0-1 bp, 0-0.1%). The new species can be distinguished from N. antipodites in having curved primary fascicles composed of non-‘audouinelloid’ cells (compared to straight primary fascicles with audouinelloid—cylindrical—cells) and in being always dioecious (only rarely is N. antipodites dioecious).

A new polypore, Rhodonia tianshanensis, collected from West Tianshan Nature Reserve in Xinjiang Autonomous Region (northwest China), is described and illustrated based on morphological characteristics and molecular evidence. It is characterized by having resupinate basidiomata with an oblique tube layer, fusoid cystidioles in the hymenium, and cylindrical basidiospores. Based on multiple loci DNA sequences including the internal transcribed spacer (ITS), the large subunit (nLSU), and the second subunit of RNA polymerase II (RPB2) regions, our phylogeny strongly supported R. tianshanensis as a new species belonging to the genus Rhodonia.

Seventeen species of Leucophenga subpollinosa species group are described from China (including 11 new species): L. argentina (de Meijere, 1924); L. flavicosta Duda, 1926; L. formosa Okada, 1987; L. nigroscutellata Duda, 1924; L. subpollinosa (de Meijere, 1914); L. umbratula Duda, 1924; L. aculeata sp. nov.; L. acuticauda sp. nov.; L. cultella sp. nov.; L. cyclophylla sp. nov.; L. flaviclypeata sp. nov.; L. fuscipedes sp. nov.; L. gracilenta sp. nov.; L. latipenis sp. nov.; L. magnicauda sp. nov.; L. rhombura sp. nov.; L. rugatifolia sp. nov. A key to all examined species of the subpollinosa group in the present study is provided. The phylogenetic relationships among the 17 species of the subpollinosa group are reconstructed by NJ (Neighbor-joining) and Bayesian analyses using 98 DNA sequences of COI (cytochrome c oxidase subunit I) gene. The pairwise intra- and interspecific p-distances of aforementioned sequences are summarized.

A New Species

During field trips to Guam and Babeldaob Islands in Micronesia, freshwater shrimps were sampled and assigned either to Caridina brachydactyla De Man, 1908 or C. mertoni J. Roux, 1911 (Decapoda: Atyidae), following previous inventories. In combining morphological data with a genetical analysis, it appeared that all the specimens belonged to a new species, Caridina variabilis sp. nov., here described with its distribution. The status of this new species is clarified and finally, neither C. brachydactyla, nor C. mertoni occur in these two islands. DNA sequences of 16S were obtained from the syntypes of C. mertoni.
