Eutrema nanum (Brassicaceae), a new species from Chola Shan, Southwest China

Eutremananum, a new high-elevation (4500–4600 m) species from Chola Shan, Sichuan (Southwest China), is described and illustrated. It is similar morphologically to E.nepalense but is readily distinguished by having oblong to elliptic or obovate to spatulate (vs. suborbicular to broadly ovate) leaves, glabrous (vs. puberulent) sepals and ovate to oblong fruit 4–7 × 2–3 mm with flattened valves (vs. ovoid to subglobose fruit 2–3 × 1.8–2 mm with rounded valves). The genetic differences amongst E.nanum, E.nepalense and other close relatives are further confirmed by phylogenetic analyses using ITS and cpDNA sequence variations. The new combination E.sinense is proposed.

A New Species

An adult sand snake specimen was collected during a herpetofaunal survey conducted in the Turpan Basin in northwest China. Phylogenetic analyses revealed that this specimen, along with other snake sloughs and skins collected from different localities in the Turpan Basin formed a clade that is sister to Psammophis lineolatus. This taxon exhibited substantial divergence from its congeners (P. lineolatus and P. condanarus) with uncorrelated p-distances ranging from 11.9 ± 0.9% to 15.8 ± 1.6% for the ND4 gene and from 10.2 ± 0.8% to 13.8 ± 1.1% for the Cytb gene. Given the genetic differences along with morphological differences, we describe the specimen from the Turpan Basin as Psammophis turpanensis sp. nov. We provide detailed morphological descriptions, and compare this specimen with five Asian sand snakes and the Afro-Asian Sand Snake, P. schokari. In addition, we provide brief comments on the biogeography of Psammophis in China.

During a survey of entomopathogenetic fungi from Southwest China, a new species, Akanthomyces lepidopterorum was found on an undetermined lepidopteran larva. It differs from other species based on mostly smaller conidia, mononematous conidiophores and moderate length of phialide. Both the morphological identification and phylogenetic analysis of combined ITS, LSU and RPB2 sequence data support A. lepidopterorum as a new species. A new combination is also proposed in the genus Akanthomyces.

Ottelia fengshanensis, a new species (Hydrocharitaceae) from southwest China is here described and illustrated. Comparing its morphological features to putative close relatives O. guanyangensis, it has 3–4 flowers (vs. 2–5) each spathe, hexagonal-cylindric fruit, white styles (vs. yellow), green leaves (vs. dark green) and fruit tiny winged (vs. winged obviously). Molecular phylogenetic investigation of four DNA sequences (ITS, rbcL, trnK5’ intron and trnS-trnG) and the Poisson Tree Processes model for species delimitation (PTP) analysis, further resolves O. fengshanensis as a new species that is close to O. guanyangensis with distinct support.

A New Species

AbstractA new species of Synarthonia, S. leproidica, is described from Luxembourg. Phylogenetic analyses of mtSSU and RPB2 sequences were used to determine the generic affiliation of this sterile species. Synarthonia leproidica differs from all other species of the genus by the combination of a leproid thallus and the production of psoromic acid. It is the sister species to S. muriformis in our phylogenetic analyses. The discovery of the new species suggests that other strictly sorediate lichen species might have been overlooked in Europe, even in intensely explored countries such as Luxembourg. Phylogenetic analyses further confirm the placement of Reichlingia anombrophila in the genus Reichlingia and of Synarthonia astroidestera in the genus Synarthonia. Arthonia atlantica is transferred to the genus Reichlingia as R. dendritica.

The generic group names Cymella Felder, 1874 and Myclela Watson, Fletcher & Nye, 1980 are excluded from the subtribe Nudariina and synonymized with the nominate subgenus of the genus Stigmatophora Staudinger, 1881 belonging to the subtribe Endrosiina. The type species of Cymella and Myclela, Cymella congerens Felder, 1874 is synonymized with the nominate subspecies of Stigmatophora (Stigmatophora) rhodophila (Walker, [1865]). The type locality of Cymella congerens is designated as Shanghai (E China). Two taxa previously treated as synonyms of S. congerens are upgraded to the species level and left in the genus Miltochrista Hübner, [1819]: Miltochrista artocarpi (Moore, 1878), stat. nov. and Miltochrista roseogrisea (Rothschild, 1913), stat. nov. The genus Asuropsis Matsumura, 1927 is excluded from the synonymy of Miltochrista and synonymized with the nominate subgenus of the genus Stigmatophora. The new combination is established: Stigmatophora (Stigmatophora) ranruna (Matsumura, 1927), comb. nov. A new species, Stigmatophora (Stigmatophora) cernyi Volynkin, sp. n. is described from North Thailand and Southwest China. Adults of both sexes of all the species mentioned and their genitalia are illustrated.

Ant-pathogenic fungi are mainly found in the Ophiocordycipitaceae, rarely in the Cordycipitaceae. During a survey of entomopathogenetic fungi from Southwest China, a new species, Cordyceps yinjiangensis, was isolated from the ponerine. It differs from other Cordyceps species by its ant host, shorter phialides, and smaller septate conidia formed in an imbricate chain. Phylogenetic analyses based on the combined datasets of (LSU+RPB2+TEF) and (ITS+TEF) confirmed that C. yinjiangensis is distinct from other species. The new species is formally described and illustrated, and compared to similar species.

A New Species

In this study, fungal specimens of the family Diatrypaceae were collected from karst areas in Guizhou, Hainan and Yunnan Provinces, China. Morpho-molecular analyses confirmed that these new collections comprise a new genus Pseudodiatrype, three new species (Diatrype lancangensis, Diatrypella pseudooregonensis and Eutypa cerasi), a new combination (Diatrypella oregonensis), two new records (Allodiatrype thailandica and Diatrypella vulgaris) from China and two other known species (Neoeutypella baoshanensis and Paraeutypella citricola). The new taxa are introduced, based on multi-gene phylogenetic analyses (ITS, β-tubulin), as well as morphological analyses. The new genus Pseudodiatrype is characterised by its wart-like stromata with 5–20 ascomata immersed in one stroma and the endostroma composed of thin black outer and inner layers of large white cells with thin, powdery, yellowish cells. These characteristics separate this genus from two similar genera Allodiatrype and Diatrype. Based on morphological as well as phylogenetic analyses, Diatrype lancangensis is introduced as a new species of Diatrype. The stromata of Diatrype lancangensis are similar to those of D. subundulata and D. undulate, but the ascospores are larger. Based on phylogenetic analyses, Diatrype oregonensis is transferred to the genus Diatrypella as Diatrypella oregonensis while Diatrypella pseudooregonensis is introduced as a new species of Diatrypella with 8 spores in an ascus. In addition, multi-gene phylogenetic analyses show that Eutypa cerasi is closely related to E. lata, but the ascomata and asci of Eutypa cerasi are smaller. The polyphyletic nature of some genera of Diatrypaceae has led to confusion in the classification of the family, thus we discuss whether the number of ascospores per asci can still be used as a basis for classification.

A New Species

A new Seifertia species was isolated from hanging rachides of Rhododendron decorum in Yunnan Province, Southwest China. The new taxon was compared with the type species, S. azalea and differs in having wider conidiophores, with hyaline to subhyaline and smaller conidia, while S. azalea has olive-brown to brown, rarely branched conidiophores, and pale brown or olive-brown, very rarely septate conidia. Phylogenetic analyses of combined LSU, SSU and TEF1-α sequence data show that S. shangrilaensis forms a robust clade with S. azalea nested among the species of Melanommataceae in the order Pleosporales. A new species, S. shangrilaensis is introduced in this study, and Seifertia should be placed in Melanommataceae (Pleosporales, Dothideomycetes) based on phylogenetic analysis. Description and illustration of Seifertia shangrilaensis are provided with notes and its introduction is supported by molecular data.
