A new species of atyid freshwater shrimp is described from two caves of Bac Kan Province, Northeast Vietnam, namely Caridina namdat sp. nov. This species can be distinguished from its congeners by a suite of morphological characters such as reduced eyes with short eyestalk, very short and unarmed rostrum, slender second pereiopod, elongated endopod of male first pleopod, and long appendix interna of the male second pleopod. Molecular phylogenetic data from the mitochondrial cytochrome oxidase subunit I (COI) and 16S ribosomal RNA genes also support the distinctiveness of the new species from all other examined species.

The first stygobitic species of atyid freshwater shrimps from Vietnam is described from Cuc Phuong National Park, Northern Vietnam. Caridina thachlam sp. nov. can be distinguished from its congeners by a suite of morphological characters such as strongly reduced eyes without eyestalk, short and almost unarmed rostrum and slender pereiopods. Molecular phylogenetic data from the mitochondrial cytochrome oxidase subunit I (COI) and 16S ribosomal RNA genes also support the distinctiveness of the new species from all other species that we have examined.

During this investigation, a new species of Melanoleuca subg. Urticocystis with urticiform cheilocystidia is proposed. The identification is based on morphological characters and molecular phylogenetic analyses using ITS and 28S sequences. A comparison of the morphological features and molecular phylogenetic data with the taxa of subg. Urticocystis confirms the identity of the species as a new taxon. The detailed descriptions, line drawings and phylogenetic results are given.

Molecular Phylogenetic Data

A new species, Amanita glarea, is described and illustrated from Pakistan. Molecular phylogenetic data derived from internal transcribed spacer (ITS) and nuclear ribosomal large subunit (LSU) regions along with morphological characters make it distinct from other currently known Amanita species. Amanita glarea is characterized by a grayish brown, slightly umbonate, pileus having universal veil remnants and striate margins, a long ringless stipe with a saccate volva bearing yellowish brown patches on the verrucose surface, inamyloid globose to subglobose basidiospores, and a filamentous pileipellis with some inflated round to elongated cells. Phylogenetic analysis of nuclear ribosomal ITS and LSU nucleotide sequences resolve A. glarea with other taxa in Amanita section Vaginatae.

Rimicaris hybisaesp. nov. is described from hydrothermal vent fields on the world's deepest seafloor spreading centre, the Mid-Cayman Spreading Centre (MCSC), Caribbean, at depths of 2300–4960 m. The new species is described and illustrated on the basis of 17 specimens. Brief notes on the distribution and habitat of the new species are provided. Molecular phylogenetic data from mitochondrial COI (460 base pair (bp)), 16S ribosomal RNA (549 bp) and nuclear 18S ribosomal RNA (576 bp) regions is used to complement the description. Morphological variation withinR. hybisaesp. nov. and morphological affinities with previously described species are discussed. Based on morphological and molecular evidence, the new species is provisionally assigned to the genusRimicaris, and differs from all known species in the genus by a distinctive pair of ‘pores' on the posterior lobes of its four-lobed dorsal organ. An emended diagnosis forRimicarisis provided.Rimicaris hybisaesp. nov. is the first taxon to be described from MCSC vent fields. This record extends the known geographical range ofRimicarisinto the Caribbean Sea and constitutes the deepest documented occurrence of alvinocaridid shrimp.

A New Species

A new species, Scrophularia jinii (Scrophulariaceae), from Central China is described and illustrated. This new species was formerly misidentified as S. fargesii, from which it differs in many morphological characters. Moreover, it is distinct with all known Scrophularia species in its unique deeply double serrate leaf margin with 3–7 big teeth on each side. Molecular phylogenetic analysis further supports its species delimitation and suggests a close relationship with several Japanese and North American species.

A New Species

Based on molecular phylogenetic analyses and morphological characters, a new species from Bangladesh, northern Vietnam, and southwestern China, Leptolejeunea nigra, is described. It is mostly similar to L. balansae but remarkable for having brownish black ocelli in its leaf lobes. In the molecular phylogeny, the samples of L. nigra are not nested within any clade and form an independent lineage. In particular, the molecular dating suggested that the divergence of L. nigra happened in time span of the formation of the Himalayas.

Paris lihengiana (Melanthiaceae), a new species from Yunnan Province, China, is described and illustrated based on evidence from morphological characters and molecular phylogeny. It differs from other species of Paris in its pubescent stem, pedicel and abaxial leaf surface, as well as other characters. Molecular phylogenetic analysis of 33 taxa in Paris was conducted based on nuclear ribosomal ITS and six plastid markers. Paris lihengiana is supported as a new species by both morphological characters and molecular data.

AbstractSerpentirhabdias viperidicus n. sp. (Nematoda: Rhabdiasidae) is described from the lungs of the ‘Brazilian lancehead’ Bothrops moojeni (Hoge, 1966) from the savannah in São Paulo State, Brazil. The new species is the eighth species of Serpentirhabdias described in the Neotropical region, and differs from other species mainly by a combination of characters: lips slightly notable, presence of fine striations at posterior ends, presence of two parallel lines with intercalated pores, a pore-shaped phasmid situated at the level of the anal aperture and another two in the posterior half of the tail. It is the first species of Serpentirhabdias reported in this snake host and the second species of this genus found parasitizing South American viperidian snakes. Molecular phylogenetic analysis using ribosomal (ITS and 28S partial) genes confirms Serpentirhabdias viperidicus n. sp. as a new species that clustered in the Serpentirhabdias clade, sister taxon to Serpentirhabdias fuscovenosa and Serpentirhabdias elaphe. This is the first description of Serpentirhabdias species from Brazil using molecular approaches and morphological characters to confirm the monophyly of this recent genus.

Allium xinlongense from western Sichuan Province, China, is described as a new species. Its diagnostic morphological characters were confirmed to be valid by comparing them to those of related species, such as A. maowenense, A. chrysanthum, A. rude, A. xichuanense, A. chrysocephalum, and A. herderianum. Molecular phylogenetic analysis (combining ITS and rpL32-trnL markers) indicated that this new species is a member of Allium sect. Daghestanica. A comprehensive description of this new species is provided, including habitat environment and detailed morphological traits.
