The study presents preliminary data on monitoring of Rhododendron brachycarpum D. Don ex G. Don fil.,a rare species of the Kunashir island flora. Comparative morphological and molecular phylogenetic analyses were carriedout with samples of R. brachycarpum and R. fauriei Franch from the island of Kunashir, the Sikhote-Alin Nature Reserve,and Japan (Honshu and Hokkaido islands). R. brachycarpum and R. fauriei are species with fuzzy boundaries concerningsystematics. The internal transcribed spacers (ITS1-5.8S-ITS2) in nrDNA were chosen as molecular markers. Preliminaryresults support the consideration that R. fauriei and R. brachycarpum are two separate species.

Based on morphological and molecular phylogenetic studies, Semiaquilegia danxiashanensis, a new species from Danxia Shan in northern Guangdong, southern China, is described and illustrated. This species is easily distinguishable from each of other three known species in the genus by characters of the flowers and fruits. In addition, molecular phylogenetic analyses of both the nuclear ITS and the plastid trnL-F region strongly supported S. danxiashanensis as a separate species from other species of Semiaquilegia. We provide a detailed morphological and habitat description, distribution, as well as colour photographs and illustrations of the new species.

Morphological Differences

Numerous nominal species have been considered synonymous with Carybdea alata Reynaud, 1830 (cf. Gershwin 2005). A recent revision concluded that several of the species collectively referred to as C. alata are valid and indeed separate species (Gershwin 2005; but see also Bentlage et al. 2010). Additionally, these species (including C. alata) were moved into the genus Alatina Gershwin 2005 (family Alatinidae Gershwin, 2005) because of stark morphological differences they display compared to the other species of Carybdea. In particular, Alatina species possess crescentic phacellae and a rhopaliar niche ostium that is covered by a single upper and two lateral scales (t-shaped sensu Gershwin 2005; cf. Bigelow 1938) compared to a single upper covering scale (heart-shaped sensu Gershwin 2005; cf. Bigelow 1938) and epaulette-like or linear phacellae in the corners of the stomach in Carybdea species. Recent molecular phylogenetic analyses support the separation of Carybdea and Alatina (Bentlage et al. 2010). Alatina grandis posed a problem in Gershwin's (2005) revision, as the type of this species appeared to be lost to science, preventing a closer investigation of its identity. I located a type specimen of the species in the collections of the National Museum of Natural History, Smithsonian Institution (USNM). The purpose of this letter is to draw attention to this important specimen, and highlight directions for future studies on the evolutionary history of the genus Alatina.

The type of Rossbeeverabispora and additional collections from the type location and adjacent areas were studied. Molecular data for R.bispora derived from the new collections are provided. In addition, R.griseobrunnea, a new species of Rossbeevera, is described from Xiangtoushan National Nature Reserve, Guangdong Province of China. The new species is characterized by its globose to subglobose sequestrate basidiomata with grayish white to grayish brown pileus, pale bluish discoloration in some parts of the hymenophore when injured becoming rusty brown to dark brown after being exposed to the air, fusoid (star-shaped in cross section) basidiospores 17–20 × 9–12 μm, and subcutis elements in the pileus. Based on multi-locus (ITS+nrLSU+tef1-α+rpb2) molecular phylogenetic analyses, both species appear as sister to R.paracyanea. We present color photos, macro- and micro-description, SEM basidiospores, molecular affinities of the species and compare them with morphologically similar taxa within the genus. A key to the species known from northern and southern hemispheres is provided.

A new species of agaricomycetes, Clitopilus lampangensis, is described based on collections from northern Thailand. This species was distinguished from previously described Clitopilus species by its pale yellow to grayish yellow pileus with the presence of wider caulocystidia. Molecular phylogenetic analyses, based on the data of the internal transcribed spacers (ITS) and the large subunit (LSU) of the nuclear ribosomal DNA, and the second largest subunit of RNA polymerase II (rbp2) genes, also support the finding that C. lampangensis is distinct from other species within the genus Clitopilus. A full description, color photographs, illustrations and a phylogenetic tree showing the position of C. lampangensis are provided.

English Spelling

Anderson (1875: 282) originally introduced the nomen Pteromys yunanensis for the Yunnan flying squirrel and later (Anderson 1879: 282) redescribed it as Pteromys yunnanensis, likely to fit with the alternative English spelling ‘Yunnan’ for the name of this Chinese province. Subsequently this species was transferred to the genus Petaurista Link, 1795 by Robinson & Kloss (1918: 173), which includes many recognized species and subspecies. Later on, it was considered a synonym of either Petaurista petaurista (Pallas, 1766) or Petaurista philippensis (Elliot, 1839) in subsequent taxonomic revisions (Ellerman & Morrison-Scott 1951; Corbet & Hill 1992; Thorington & Hoffmann 2006) until recent molecular phylogenetic analyses found it to be a separate species (Yu et al. 2006). More recent phylogenetic analyses have confirmed its species rank (e.g., Oshida et al. 2010; Casanovas-Vilar et al. 2018) and recent revisions have considered it a distinct species (Jackson 2012; Jackson & Thorington 2012; Koprowski et al. 2016).

Basal Position

The Artematopodidae is a species-poor beetle family with contentious relationships to byrrhoid and elateroid families. Recent molecular phylogenetic analyses brought ambiguous results based on a single sequenced species. We investigated the taxonomic placement of Artematopodidae within Elateriformia using ribosomal (18S, 28S) and mitochondrial (rrnL, cox1) molecular markers and three artematopodid species. Our analyses placed Artematopodidae close to Omethidae+Telegeusidae in a basal position of broadly defined Elateroidea. Additionally, we described the first artematopodid species from China – Eurypogon jaechi sp. nov. and E. heishuiensis sp. nov. These species are reported from mountains of Yunnan and can be easily distinguished from their Palaearctic congeners by their large bodies and metallic green elytra. They differ from each other by the shape of the pronotum, puncturation of the head and pronotum, the relative lengths of the antennomeres 3-5, and the morphology of the female genitalia. With respect to our findings, we discussed the phylogeny, diversity and distribution of the family Artematopodidae.

28S Ribosomal Dna

The phylogenetic position of three taxa from two trematode genera, belonging to the subfamily Acanthostominae (Opisthorchioidea: Cryptogonimidae), were analysed using partial 28S ribosomal DNA (Domains 1–2) and internal transcribed spacers (ITS1–5.8S–ITS2). Bayesian inference and Maximum likelihood analyses of combined 28S rDNA and ITS1 + 5.8S + ITS2 sequences indicated the monophyly of the genusAcanthostomum(A.cf.americanumandA. burminis) and paraphyly of the Acanthostominae.These phylogenetic relationships were consistent in analyses of 28S alone and concatenated 28S + ITS1 + 5.8S + ITS2 sequences analyses. Based on molecular phylogenetic analyses, the subfamily Acanthostominae is therefore a paraphyletic taxon, in contrast with previous classifications based on morphological data. Phylogenetic patterns of host specificity inferred from adult stages of other cryptogonimid taxa are also well supported. However, analyses using additional genera and species are necessary to support the phylogenetic inferences from this study. Our molecular phylogenetic reconstruction linked two larval stages ofA.cf.americanumcercariae and metacercariae. Here, we present the evolutionary and ecological implications of parasitic infections in freshwater and brackish environments.

Species of the viviparous monogenean genus Gyrodactylus are difficult to identify morphologically and relationships within the genus are unclear. Partial or complete sequences were obtained for the internal transcribed spacers (ITS-1 and ITS-2) and 5.8S ribosomal DNA (rDNA) of 11 Gyrodactylus species (G. kobayashii, G. gurleyi, G. pungitii, G. rogatensis, G. gasterostei, G. derjavini, G. salaris, G. rarus, G. turnbulli, G. bullatarudis, and G. arcuatus) and the related Gyrdicotylus gallieni. Phylogenetic analyses (parsimony, distance, and maximum likelihood) separated species of the Gyrodactylus wageneri species-group (with a long ITS-1) from those of the Gyrodactylus eucaliae and G. arcuatus species-groups (with a short ITS-1). This subdivision into species with a long (610-630 base pairs (bp)) or short (300-500 bp) ITS-1 was also apparent with 5.8S rDNA and ITS-2 data. No support could be found for the hypothesis that G. salaris is a member of a separate species group, as this species clustered within the G. wageneri group. The morphologically homogeneous G. wageneri group was subdivided by our molecular data into five species that infect cottids, gasterosteids, and salmonids and two species that infect cyprinid fishes. Overall, the ITS-2, combined with the 5.8S rDNA (an alignment of 668 bp), appeared to be the most informative indicator of phylogenetic relationships within the genus Gyrodactylus. The potential importance of this technique for future gyrodactylid systematics is discussed.

AbstractIn Antarctica, the genus Bartramia has been restricted to a single polymorphic species, B. patens. Its status as a separate species or a subspecies of the Northern Hemisphere B. ithyphylla was debated. In the present paper, we combine analyses of chloroplast (trnS–rps4–trnT–trnL–trnF region) and nuclear ITS sequences with a reinvestigation of morphological characteristics to infer the identity of Antarctic Bartramia. Phylogenetic and Automatic Barcode Gap Discovery (ABGD) species delimitation analyses indicate that the species diversity of Bartramia in Antarctica has been underestimated, since two species were identified, both belonging to Bartramia sect. Pyridium. Of these, B. subsymmetrica is a new record of the species for Antarctica, as it has previously only been recorded from Livingston Island, South Shetlands. The other species is B. patens, which is separated from B. ithyphylla by newly inferred morphological characteristics and is a sister species to the latter in the molecular phylogenetic analyses. Consequently, we consider B. ithyphylla to be a Northern Hemisphere instead of a bipolar species. The suggested conspecificity of both taxa into one species in the ABGD analysis is considered to result from overlumping by this species delimitation method. The delimitation of the three species of section Bartramia (B. halleriana, B. mossmaniana and B. pomiformis) and the circumscription of the genus Bartramia are discussed.
