A New Species

A new species of Koorchaloma is described based on morphology and multigene phylogenetic analyses of ITS, LSU and RPB2. Phylogenetic analyses showed our strain clusters with K. europaea with moderate statistical support. Koorchaloma oryzae sp. nov. is morphologically similar to K. europaea, but it can be distinguished by the conidiophores and conidia, while ITS pairwise nucleotide comparison of these two species also revealed differences. Koorchaloma oryzae is compared with all known Koorchaloma species, and a key to Koorchaloma species is provided. Genealogical concordance phylogenetic species recognition analysis (PHI test) results of the new species and closely related species are also given.

The genus Coniochaeta is an important ascomycete because its members live in diversified habitats and nutritional modes. In this study, two new species, C. acaciae and C. coluteae, are introduced from dead branches of Acacia sp. and Colutea paulsenii Freyn (both Fabaceae) respectively from Uzbekistan, based on morphological and phylogenetic studies. Analyses of combined ITS and LSU sequence data with Genealogical Concordance Phylogenetic Species Recognition (GCPSR) and comparison of similar taxa, provide evidences for placement of these new species in Coniochaeta, as distinct lineages.

A new species of colubrid snake, Lycodon cathayasp. nov., is described based on two adult male specimens collected from Huaping Nature Reserve, Guangxi, southern China. In a phylogenetic analyses, the new species is shown to be a sister taxon to the clade composed of L. futsingensis and L. namdongensis with low statistical support, and can be distinguished from all known congeners by the significant genetic divergence in the mitochondrial cytochrome b gene fragment (p-distance ≥ 7.9%), and morphologically by the following combination of characters: (1) dorsal scales in 17–17–15 rows, smooth throughout; (2) supralabials eight, third to fifth in contact with eye, infralabials nine; (3) ventral scales 199–200 (plus two preventral scales), subcaudals 78; (4) loreal single, elongated, in contact with eye or not, not in contact with internasals; (5) a single preocular not in contact with frontal, supraocular in contact with prefrontal, two postoculars; (6) maxillary teeth 10 (4+2+2+2); (7) two anterior temporals, three posterior temporals; (8) precloacal plate entire; (9) ground color from head to tail brownish black, with 31–35 dusty rose bands on body trunk, 13–16 on tail; (10) bands in 1–2 vertebral scales broad in minimum width; (11) bands separate ground color into brownish black ellipse patches arranged in a row along the top of body and tail; (12) elliptical patches in 3–6 scales of the vertebral row in maximum width; (13) ventral surface of body with wide brownish black strip, margined with a pair of continuous narrow greyish white ventrolateral lines. With the description of the new species, 64 congeners are currently known in the genus Lycodon, with 16 species occurring in China.

Ophiocordyceps is entomopathogenic and the largest studied genus in the family Ophiocordycipitaceae. Many species in this genus have been reported from Thailand. The first new species introduced in this paper, Ophiocordycepsglobiceps, differs from other species based on its smaller perithecia, shorter asci and secondary ascospores and additionally, in parasitising fly species. Phylogenetic analyses of combined LSU, SSU, ITS, TEF1α and RPB1 sequence data indicate that O.globiceps forms a distinct lineage within the genus Ophiocordyceps as a new species. The second new species, Ophiocordycepssporangifera, is distinguished from closely related species by infecting larvae of insects (Coleoptera, Elateridae) and by producing white to brown sporangia, longer secondary synnemata and shorter primary and secondary phialides. We introduce O.sporangifera based on its significant morphological differences from other similar species, even though phylogenetic distinction is not well-supported.

Abstract— Plants from Brazilian campos rupestres usually present morphological strategies that allow them to survive in extreme environments. However, in Chamaecrista (Leguminosae, Caesalpinioideae), one of the most diverse genera in the campos rupestres, needle-like leaflets are rare. Reviewing the species that present such leaf morphology, we describe Chamaecrista acicularis, a new species from the Canastra Range, in the southwestern region of the state of Minas Gerais, Brazil. Phylogenetic analyses revealed that C. acicularis is not closely related to other quite similar needle-like leafleted species and that this trait evolved convergently. We also present comments on the phylogenetic relationships of needle-like leafleted species as well as the evolution of the leaflet amplitude, and a detailed description of C. acicularis alongside illustrations, photos, geographical distribution, a key to the needle-like leafleted species and taxonomic notes on similar species. Additionally, we expand the description of Chamaecrista strictifolia and present an informal conservation status for all needle-like leafleted species.

A New Species

This study describes a new orchid species, Cymbidium motuoense, from Xizang, China based on morphological and molecular analyses. Several unique morphological features distinguish this new orchid from all other species of Cymbidium. Based on its morphology, this orchid is similar to C. tracyanum but differs in its yellow-green flower with dark purple-red spots on the veins, oblong-elliptic sepals, side lobes of the lip with reddish brown hairs along the veins and disc with three purple-red lamellae. Phylogenetic analyses based on plastid DNA (matK and rbcL) supported C. motuoense as a new species. However, the low support in nuclear ribosomal ITS tree provide the possibility that the new orchid may be a natural hybrid of C. tracyanum and C. iridioides or another closely related species.

A New Species

A halophilic archaeon, strain F20-122T, was isolated from a marine saltern of Isla Bacuta (Huelva, Spain). Cells were Gram-stain-negative, aerobic, and coccoid in morphology. It grew at 25–50 °C (optimum 37 °C), pH 6.5–9.0 (optimum pH 8.0), and 10–30% (w/v) total salts (optimum 25% salts). The phylogenetic analyses based on the 16S rRNA and rpoB’ genes showed its affiliation with the genus Natronomonas and suggested its placement as a new species within this genus. The in silico DNA–DNA hybridization (DDH) and average nucleotide identity (ANI) analyses of this strain against closely related species supported its placement in a new taxon. The DNA G + C content of this isolate was 63.0 mol%. The polar lipids of strain F20-122T were phosphatidylglycerol phosphate methyl ester (PGP-Me), phosphatidylglycerol (PG), and phosphatidylglycerol sulfate (PGS). Traces of biphosphatidylglycerol (BPG) and other minor phospholipids and unidentified glycolipids were also present. Based on the phylogenetic, genomic, phenotypic, and chemotaxonomic characterization, we propose strain F20-122T (= CCM 8891T = CECT 9564T = JCM 33320T) as the type strain of a new species within the genus Natronomonas, with the name Natronomonas salsuginis sp. nov. Rhodopsin-like sequence analysis of strain F20-122T revealed the presence of haloarchaeal proton pumps, suggesting a light-mediated ATP synthesis for this strain and a maximum wavelength absorption in the green spectrum.

A new species of Limnonectes is described from northeastern Vietnam based on morphological and molecular differences. Morphologically, the new species is distinguishable from its congeners on the basis of a combination of the following diagnostic characters: Large size (SVL 50.1–68.9 in males, 45.5–63.0 mm in females); males with moderately enlarged head (HL/SVL 0.48), head longer than wide; vomerine teeth present; external vocal sacs absent; rostral length short (RL/SVL 0.16 in males, 0.15 in females); tympanum distinct (TD/ED 0.63 in males, 0.60 in females); dorsal surface of head, body and flanks with flattened tubercles; dorsal surface of tibia possessing small tubercles; supratympanic fold present; dorsolateral fold absent; webbing formula I0–0II0–1/3III0–1/3IV1/2–0V; in life, dorsum yellowish brown with a dark brown marking; throat and chest white with dark brown marking; ventral surface of fore and hind limbs as well as belly white. In phylogenetic analyses, the new species is placed as the sister taxon to Limnonectes fujianensis with strong statistical support in all analyses.

Species of Psilocybe collected in Yunnan Province in southwest China were identified using both morphological characteristics and phylogenetic analyses of ITS and nrLSU sequence data. Six phylogenetic species were recognized among the studied collections. In this paper, Psilocybe ruliensis is introduced as a new species, while Psilocybe keralensis is new to China, P. aff. fasciata is new to Yunnan and P. chuxiongensis is recollected in Yunnan Province. The remaining two phylogenetic species are not described or detailed due to the paucity of the material. The four species appear to be endemic to Asia.

Genealogical Concordance

The phylogentic diversity of the genus Morchella has only been sporadically studied in Central Europe. In this study, a molecular taxonomic revision of the Morchella species of the Czech Republic was performed using available fungarium specimens, fresh collections, and axenic cultures. Molecular phylogenetic analyses based on either ITS or five-locus (ITS, LSU, RPB1, RPB2, and EF-1α) sequencing and the application of principles of the genealogical concordance phylogenetic species recognition (GCPSR) have revealed the occurrence of 11 phylogenetic species in the region, but only six of them could be assigned unequivocally to the previously published phylospecies: Mel-3 (M.semilibera), Mel-10 (M.importuna), Mel-19 (M.eohespera), Mes-4 (M.americana), Mes-5 and Mes-8 (M.esculenta). One lineage was identified as a new phylospecies and is designated as Mel-39. Four lineages grouped together with two or more previously published phylospecies: Mel-13/26 (M.deliciosa), Mel-15/16 (M.angusticeps / M.eximioides), Mel-20/34 (M.purpurascens), and Mel-23/24/31/32 (M.pulchella). Our phylogenetic analyses and literature review shed light on the pitfalls of current molecular taxonomy of morels and highlight the ambiguities of present species recognition concepts. The main source of the problems seems to be rooted in the application of different methods (multigene vs single-gene sequencing, phenotypic determination) and approaches (monophyly vs paraphyly, the application or not of GCPSR, degree of differentiation between accepted species, etc.) by various authors for the delimitation of new phylospecies. Therefore, we propose five criteria for distinguishing new phylospecies in the genus Morchella based on molecular data, and recommend a more conservative approach in species delimitation.
