The Chaetosphaeriaceae are a diverse group of pigmented, predominantly phialidic hyphomycetes comprised of several holomorphic genera including Chaetosphaeria, the most prominent genus of the family. Although the morphology of the teleomorphs of the majority of Chaetosphaeria is rather uniform, their associated anamorphs primarily exhibit the variability and evolutionary change observed in the genus. An exception from the morphological monotony among Chaetosphaeria species is a group characterised by scolecosporous, hyaline to light pink, multiseptate, asymmetrical ascospores and a unique three-layered ascomatal wall. Paragaeumannomyces sphaerocellularis, the type species of the genus, exhibits these morphological traits and is compared with similar Chaetosphaeria with craspedodidymum- and chloridium-like synanamorphs. Morphological comparison and phylogenetic analyses of the combined ITS-28S sequences of 35 isolates and vouchers with these characteristics revealed a strongly-supported, morphologically well-delimited clade in the Chaetosphaeriaceae containing 16 species. The generic name Paragaeumannomyces is applied to this monophyletic clade; eight new combinations and five new species, i.e. P. abietinussp. nov., P. eleganssp. nov., P. granulatussp. nov., P. sabinianussp. nov. and P. smokiensissp. nov., are proposed. A key to Paragaeumannomyces is provided. Using morphology, cultivation studies and phylogenetic analyses of ITS and 28S rDNA, two additional new species from freshwater and terrestrial habitats, Codinaea paniculatasp. nov. and Striatosphaeria castaneasp. nov., are described in the family. A codinaea-like anamorph of S. castanea forms conidia with setulae at each end in axenic culture; this feature expands the known morphology of Striatosphaeria. A chaetosphaeria-like teleomorph is experimentally linked to Dendrophoma cytisporoides, a sporodochial hyphomycete and type species of Dendrophoma, for the first time.

A new species of the genus Thalassironus de Man, 1889 was discovered during several surveys of the offshore marine ecosystem in Korea. This new species belonging to the family Ironidae, Thalassironus koreanus sp. nov., shares general morphological traits of the genus such as an optically smooth cuticle, buccal cavity consisting of two parts with three movable teeth and thick cuticularized walls, six rounded lips with ten cephalic setae, slit-like amphid and short conical tail with caudal glands present. The new species is most closely related to T. bohaiensis, first discovered in the Bohai Sea, in terms of body ratio (a, b, c, c’) and general morphology, but differs by its generally longer and larger body structures, cervical setae at the level of the buccal cavity, paired somatic setae distributed along the body, and longer/larger spicule. A description of Thalassironus koreanus sp. nov., diagnosis of the genus, emended pictorial key for the genus and discussion of important characteristics for the genus is provided.

The phospholipids of Rhizobium japonicum were measured quantitatively, and the major phospholipids were shown to be phosphatidylserine, phosphatidylcholine, phosphatidylethanolamine, and cardiolipin. High levels of phosphatidylethanolamine and phosphatidylcholine were found. Such large amounts of phosphatidylcholine have been reported previously in the pseudomonads, and smaller amounts have been found in the genus Agrobacterium of the family Rhizobiaceae. The phospholipid composition of R. japonicum suggests a taxonomic relationship with the pseudomonads.

The first data on the oribatid mites of Myanmar are presented and these belong to the family Otocepheidae. A new species of the genus Eurostocepheus (Oribatida, Otocepheidae) is described from litter of disturbed primary forest of Nat Ma Taung National Park in the Chin State. Eurostocepheus (Eurostocepheus) peterjaegeri sp. nov. is morphologically most similar to E. (E.) mahunkai Mondal & Kundu, 1999, but differs by the shorter notogastral setae c and la compared to the other notogastral setae, setae la pressed to notogastral surface, well-developed lateral prodorsal carinae, smooth genital plates and by the presence of diagonal ridges on the anal plates. A supplementary description of Otocepheus (Otocepheus) heterosetiger Aoki, 1965 which was originally described from Thailand, is given in detail on the basis of specimens from Myanmar. The main morphological traits for this species are summarized.

Abstract Anthemis L. is a genus of aromatic flowering plants in the family Asteraceae and is native to Iran. In this research, 62 accessions of four chamomile species including Anthemis tinctoria, A. triumfetti, A. haussknechtii and A. pseudocotula were evaluated for morphological traits. Four experiments were conducted using a randomized complete block design with three replications at the Research Institute of Forest and Rangeland, Tehran, Iran in 2011. Data were collected for the morphological traits for all of the species and essential oil content for A. triumfetti and A. pseudocotula. The results showed that plant height was positively correlated with canopy area for all of the species except A. triumfetti (p < 0.01). There were positive correlations between flower number with plant height and canopy area in both A. tinctoria and A. haussknechtii (p < 0.01). Fresh and dry weight were positively correlated with canopy area and plant height in all of the species (p < 0.01), except A. tinctoria for canopy area and A. triumfetti for plant height. GDD had a positive correlation with canopy area for A. triumfetti (p < 0.05). There was a positive correlation between essential oil yield and plant height, fresh and dry weight in A. triumfetti and A. pseudocotula (p < 0.05). Using cluster analysis (Ward method), the accessions of A. triumfetti, A. tinctoria, A. haussknechtii and A. pseudocotula were grouped into 3, 2, 4 and 2 clusters, respectively. The results of cluster analysis separated the accession based on shoot yield, morphological traits and maturity. In some items, the accessions within each cluster were coordinated with their geographical provenance.

AbstractHigher systematics within the Digenea, Carus 1863 have been relatively stable since a phylogenetic analysis of partial nuclear ribosomal markers (rDNA) led to the erection of the Diplostomida Olson, Cribb, Tkach, Bray, and Littlewood, 2003. However, recent mitochondrial (mt) genome phylogenies suggest this order might be paraphyletic. These analyses show members of two diplostomidan superfamilies are more closely related to the Plagiorchiida La Rue, 1957 than to other members of the Diplostomida. In one of the groups implicated, the Diplostomoidea Poirier, 1886, a recent phylogeny based on mt DNA also indicates the superfamily as a whole is non-monophyletic. To determine if these results were robust to additional taxon sampling, we analyzed mt genomes from seven diplostomoids in three families. To choose between phylogenetic alternatives based on mt genomes and the prior rDNA-based topology, we also analyzed hundreds of ultra-conserved elements (UCEs) assembled from shotgun sequencing. The Diplostomida was paraphyletic in the mt genome phylogeny, but supported in the UCE phylogeny. We speculate this mitonuclear discordance is related to ancient, rapid radiation in the Digenea. Both UCEs and mt genomes support the monophyly of the Diplostomoidea and show congruent relationships within it. The Cyathocotylidae Mühling, 1898 are early diverging descendants of a paraphyletic clade of Diplostomidae Poirier, 1886, in which were nested members of the Strigeidae Railliet, 1919; the results support prior suggestions that the Crassiphialinae Sudarikov, 1960 will rise to the family level. Morphological traits of diplostomoid metacercariae appear to be more useful for differentiating higher taxa than those of adults. We describe a new species of Cotylurus Szidat, 1928, resurrect a species of Hysteromorpha Lutz, 1931, and find support for a species of Alaria Schrank, 1788 of contested validity. Complete rDNA operons are provided as a resource for future studies.

Understanding the traits related to species colonization and invasion, is a key question for both pest management and evolution. One of the key components is flight, which has been measured for a number of insect species through radar and tethered flight mill systems, but a general understanding of insect flight at a community level is lacking. In this study, we used flight mill experiments to quantify flight abilities of moth species, and simulation experiments to study which moths in mainland China have the potential for cross-island dispersal. We found that moths from superfamily Geometroidea (family Geometridae) have the weakest flight ability among the seven Lepidoptera superfamilies, which is characterized by the shortest longest single flight (LSF), the shortest time corresponding to the longest single flight (TLSF) (timecorrespondingtothelongestsingleflight), the lowest total distance flown (TDF), and the lowest average speed during the flight (VTDF). Surprisingly, the family Pyralidae (superfamily Pyraloidea) has the highest flight endurance of all 186 species of 12 families in this study, which is unexpected, given its small size and morphological traits yet it shows the longest LSF and TLSF. The comparison between species common to mainland and islands shows that flight distance (LSF) may be more important for species spread than flight speed. The results of mainland-island simulations show that when P(LSF&gt;CD) (the proportion of individuals whose LSF is greater than the closest distance (CD) between mainland and island to the total number of individuals in the population) is less than 0.004, it is difficult for moth species to disperse to across islands without relying on external factors such as airflow. Over extended periods, with the immigration of species with strong flight abilities, islands are more likely to recruit species with stronger flight abilities.
