Parahellenia,a new genus segregated from Hellenia(Costaceae)based on phylogenetic and morphological evidence

Previous studies recognized three major lineages of the family Costaceae:a South American clade,an Asian clade and a Costus clade.However,the genus Hellenia within the Asian clade has been shown to be non-monophyletic and its morphology has not been studied carefully.Therefore,the complete plastid genomes of Hellenia species were obtained and the monophyly of Hellenia was tested through four different datasets in this study.Plastid phylogenomic analyses of Costaceae revealed that Hellenia is strongly supported as paraphyletic.Two major clades are recovered,namely the Hellenia s.s.subclade and the Parahellenia subclade.Phylogenetic analyses based on an enlarged taxon sampling of the Asian clade using a two chloroplast markers dataset(trnK intron and trnL-F spacer)confirmed the paraphyly of Hellenia.Meanwhile,morphological analyses suggested that members of the Parahellenia subclade differ from the remaining Hellenia species in many characters including inflorescences,bracts,stigma,axillary buds,floral tubes and labellum.According to the present molecular and morphological evidence,the latter subclade is recognized as a new genus,Parahellenia.Two new species are described,four new combinations are made,and identification keys are also provided.

A New Cockroach Genus of the Family Fuziidae from Northeastern China(Insecta:Blattida)

A new genus and two new species of fossil Fuziidae are described and illustrated： Parvifuzia gen. nov., P. marsa sp. nov. and P. brava sp. nov.. Both species were collected from the Middle Jurassic Jiulongshan, Formation of Daohugou, Inner Mongolia of China. In conjunction with Fuzia Vr（s）ansk（y）,Liang et Ren, 2009, the present findings allow us to demonstrate that members of the family were morphologically diverse, with body length ranging from medium （17 mm） in Fuzia to small （9.7 mm） in the present genus. Wing venation of F. dadao is complicated, but simple in the present species, and apex of male＇s cerci are sharp and forceps-like in F. dadao, but strongly curved inward and round in the new genus.

Diversity and abundance of mangrove fiddle crabs, genus Uca(Decapoda, Ocypodidae) at a mangrove in Kema,North Sulawesi, Indonesia

Mangrove ecosystems are sites with high biodiversity of benthic fauna, and fiddler crabs(genus Uca) are common benthic fauna in mangroves. The North Sulawesi in Indonesia has a good condition of mangrove while the information of the fiddler crabs is still limited. Manual samplings were conducted in wet, dry and transient seasons at a mangrove in Kema, North Sulawesi to investigate the species composition, density and distribution pattern of fiddler crabs. A total of 168 individuals, subjected to eight species of genus Uca crabs were collected at the mangrove, with U. triangularis having the highest abundance and U. annulipes having the lowest abundance.The densities of fiddle crabs were 27.56 ind./m2, 32.89 ind./m2and 14.22 ind./m2at the seaward, middle and landward zones, respectively, and the density was higher in dry and wet seasons than in transient season.

Differences in Morphological, Physiological and Growth Traits between Two Endemic Subspecies of <i>Brassica rupestris</i>Raf.: Implications for Their Conservation

The goal of this work was to analyze the phenological and physiological responses of Brassica rupestris Raf. subsp. hispida Raimondo & Mazzola and Brassica rupestris Raf. subsp. rupestris to environmental factors also in consideration of global change. We used seedlings of the two subspecies originated from wild plants from the natural habitats in Sicily and cultivated in the Botanical Garden of Rome. Leaf morphological and physiological traits and growth dynamic were analyzed as well as the response to an imposed water stress experiment. The results underlined a higher relative growth rate in plant height (RGRH, cm·cm-1·d-1) in B. rupestris subsp. rupestris also attested by the highest plant height (H, cm), leaf area (LA, cm2), specific leaf area (SLA, cm·g-1), total leaf area per plant (TLA, cm2) and total plant dry mass (PDM, g plant-1). Moreover, the significantly highest net photosynthetic rates (A, μmol CO2 m-2·s-1) during the study period of this subspecies was related to the high Chlorophyll content (Chl, SPAD units). B. rupestris subsp. rupestris was also the most tolerant subspecies to imposed water stress showing the highest relative water content (RWC, %), A and water use efficiency (WUE, μmol·mmol-1).

A new genus and species of Phenacoccinae(Hemiptera:Coccomorpha:Pseudococcidae)from northwestern China

A new genus and species,Sananicoccus nanophytoni gen.&sp.nov.,is described and illustrated based on its adult female,adult male,first-instar nymph and pupa,collected on the leaves of Nanophyton erinaceum(Pall.)Bunge(Chenopodiaceae)from Xinjiang.The new genus is similar to the genus Synacanthococcus Morrison,1920,but differs by the absence of ostioles and dorsal cerarii,and no cerarii situated on a prominent sclerotized area.

Species-or genus-dependent immunostimulatory effects of gut-derived potential probiotics

The immune regulatory effects of probiotics have been widely recognized to be strain-specific.However,it is unknown if there is a species-or genus-dependent manner.In this study,we use an in vitro mesenteric lymph node(MLN)model to systematically evaluate the immunostimulatory effects of gut-derived potential probiotics.The results exhibit an obvious species or genus consensus immune response pattern.RNA-seq shows that T cell-dependent B cell activation and antibody responses may be inherent to this model.Of the five tested genera,Akkermansia spp.and Clostridium butyrium directly activate the immune response in vitro,as indicated by the secretion of interleukin-10.Bifidobacterium spp.and Bacteroides spp.activate immune response with the help of stimuli(anti-CD3 and anti-CD28 antibodies).Lactobacillus spp.blunt the immune response with or without stimuli.Further investigations show that the cell surface protein of A.muciniphila AH39,which may serve as a T cell receptor cognate antigen,might evoke an in vitro immune activation.In vivo,oral administration of A.muciniphila AH39 influences the proportion of T regulatory cells(Tregs)in MLNs and the spleen under homeostasis in both specific pathogen-free and germ-free mice.All these findings indicate the distinct effects of different genera or species of potential gut-derived probiotics on intestinal and systemic immunity.

New Mesozoic Mesopsychidae (Mecoptera) from Northeastern China

The Mesozoic family Mesopsychidae Tillyard, 1917 presently consists of seven described genera and 13 species from the mid-Triassic to the Early Cretaceous of Australia, South Africa and Eurasia. In the present paper one new genus and three new species of fossil mesopsychids are described that add significant distributional and stratigraphic extensions to the family. This finding documents the first formal record of fossil Mesopsychidae in China. Both Lichnomesopsyche gloriae gen. et sp. nov. and L. daohugouensis gen. et sp. nov. were found from the Middle Jurassic Jiulongshan Formation of Inner Mongolia, whereas Vitimopsyche kozlovi sp. nov., of mid Early Cretaceous age, was collected from the Jehol Biota of northern Hebei Province. This new, wellpreserved material from China reveals complete and previously unknown body features, including head, antennae, mouthparts, legs and abdomen. The delicate and long proboscides of these new taxa indicate that they were feeding on externally exposed, nutrient-rich fluids of gymnospermous ovulate fructifications, and incapable of piercing surface epidermis - attributable principally to the absence of stylets. These proboscides originated, perhaps multiply, among basal Mecoptera and are functionally and structurally convergent with equivalent mouthparts borne by fossil and extant Diptera, Lepidoptera, Neuroptera and Coleoptera.
