A New Species

A new species of the genus Gonyosoma Wagler is described from Yunnan Province, China. The new species closely resembles G. prasinum (Blyth), but it is differentiated from the latter species by the following characters: precloacal plate divided, iris blue and inside of mouth greyish-white in life. Based on phylogenetic analyses of mitochondrial cytochrome b sequence data, the new species is recovered as the sister species to G. prasinum by Bayesian Inference and Maximum Likelihood analyses. The uncorrected pairwise distance between the new species and other species of the genus Gonyosoma ranged from 11.78% to 17.07% calculated using the mitochondrial cytochrome b sequence. This discovery increases the number of Gonyosoma species to seven.

A New Species

A new species of natricid snake, Smithophis linearis sp. nov., is described on the basis of a single recently collected specimen from Yingjiang County, Yunnan Province, People’s Republic of China, and three historical specimens from Yunnan and from northeastern Myanmar. The new species is assigned to the genus Smithophis on the basis of its single internasal and single prefrontal shields, and on the basis of the results of phylogenetic analysis of mitochondrial cytochrome b DNA sequence data. The new species differs from its congeners in having the following combination of characters: temporal shields present, six or more circumorbital scales, and a distinctive colour pattern comprising regular, narrow, longitudinal dark and pale lines. Morphological and cytochrome b data are consistent with the recognition of Smithophis as distinct from the genus Opisthotropis. A revised key to the identification of the species of Smithophis is provided.

A New Species

A new species of the genusLycodonis described from Cao Bang Province, Vietnam, based on three individuals with distinct differences in morphology and molecular data. The new species is differentiated from its congeners by a combination of the following characters: dorsal scales in 17-17-15 rows, smooth throughout; supralabials usually eight (rarely nine); infralabials ten; one elongated loreal on each side, in contact with the eye; precloacal plate single; ventral scales 212–218 (plus one or two preventral scales); subcaudals 90 or 91; maxillary teeth 13 or 14; dorsal surface of body with 28 or 29 light body bands; dorsal surface of tail with 13 cream bands, forming a distinct blotch in the vertebral region. Based on phylogenetic analyses of mitochondrial cytochromebsequence data, the new species is recovered as the sister species to a clade containingL. multizonatusandL. liuchengchaoiwith strong support from the Bayesian analysis. The new species is at least 7.5% divergent from other species within this clade in uncorrected pairwise distance calculated using a fragment of more than 1000 bp of the mitochondrial cytochromeb.This discovery increases the number ofLycodonspecies known from Vietnam to 16.

Four specimens of Phallus were collected during surveys in a Pinus armandii forest in Baoshan, Yunnan Province, China. Macro- and micro-characteristics, together with Internal Transcribed Spacer (ITS) sequence data, showed that the four specimens belong to a new species, here named Phallus haitangensis. The ITS phylogenetic analyses, morphological descriptions, color photographs, and line drawings are provided, and compared with closely related species in the genus.

A new orchid species, Cymbidium yunnanensis (Orchidaceae; Epidendroideae; Cymbidieae), from Yunnan Province, China, is described and illustrated. Based on morphological and molecular analyses, we demonstrate that this new species is similar to C. floribundum, but it differs in its smaller size, leaves 5–15 cm, shorter scape, white flowers with pale purplish markings on its sepals and petals, lip with purplish red blotch, petals narrowly falcate oblong and lip midlobe nearly round with column foot 1.5–2.0 mm long. Phylogenetic analyses based on nuclear ribosomal ITS and plastid (matK, rbcL) DNA sequence data support C. yunnanensis as a new species.

A New Species

We describe a new Diploderma species from Southern Yunnan Province, China. It is morphologically similar to D. chapaense, D. hamptoni, and D. yunnanense, but can be distinguished from these three species and all other congeners by its unique morphometric and meristic characters, color patterns and localized distribution range. Moreover, phylogenetic analyses of mitochondrial gene NADH dehydrogenase subunit 2 sequence data also supports this point of view; the new species differs genetically from investigated congeners by percentage distance of 8.78 to 21.15%.

A New Species

We present a systematic study of the genus Eligmodontia (sigmodontine rodents of the tribe Phyllotini) from Argentina, Bolivia, and Chile, based on molecular data. Phylogenetic relationships among 49 individuals were examined using nucleotide sequence data from the entire 1143 bp of the mitochondrial cytochrome-b gene. Unweighted parsimony, minimum evolution, maximum-likelihood (TrN+I+G), and Bayesian analyses revealed 2 major clades, representing Andean and non-Andean groups, and 6 minor clades, representing E. typus (lowland), E. typus (highland), E. morgani, E. puerulus, E. moreni, and E. hirtipes. E. typus (highland) is described as a new species based on combined data from the cytochrome-b gene, morphology, and karyology. The results indicate that the genus Eligmodontia is composed of a complex of species, most of which correspond to taxa that were described originally and each of which shows molecular cohesion within a limited geographic range. This species complex has relevance to current theories regarding the speciation patterns and the historical biogeography of South American sigmodontine rodents. The biogeographic history of the genus also is outlined.

A new orchid species, Cymbidium daweishanense, from Yunnan Province, China, is described based on morphological and molecular analyses and illustrated. A detailed comparison between the newly discovered orchid and other members of Cymbidium was conducted. The new plant was similar to C. erythraeum, C. subgenus Cyperorchis, but differs in having smaller flowers, a lip free from even the basal margins of column and a glabrous column with many purple blotches. The phylogenetic analyses based on nuclear ribosomal ITS and plastid (matK, rbcL) sequence data support the status of C. daweishanense as a new species.

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.

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.

A New Species

A new species of the xenodermatid snake genus Achalinus Peters, 1869 is described from Yunnan Province, Southwest China, based on a single male specimen. The new species is assigned to the genus Achalinus on the basis of absence of preocular and postocular, subcaudals arranged in single row, and results of phylogenetic analyses of mitochondrial DNA CO1 sequence data. Achalinus pingbianensis sp. nov. differs from its congeners by the combination of following morphological characters: absence of a loreal, internasals subequal to that between prefrontals and dorsal scales strongly keeled, 23 rows throughout. Currently, 13 species are in the genus Achalinus, further taxonomical and phylogenetic studies based on more extensive samples and more markers will help understand the cryptic diversity and clarify their interspecific relationships.
