A new species of <Emphasis Type="Italic">Pareledone</Emphasis> (Cephalopoda: Octopodidae) from Antarctic Peninsula Waters

During recent cruises aboard RV Polarstern in the Antarctic Peninsula region, a new species of benthic octopodid was discovered whose generic affinities based on morphological characteristics were uncertain. Molecular sequence analysis of six mitochondrial and nuclear genes allows this species to be placed with confidence within the genus Pareledone. The species is described herein and morphological diagnostic characters are provided for its identification.

A survey of Turkish Glyptomorpha (Hymenoptera, Braconidae, Braconinae) fauna with redescription of G. baetica from a new host

Glyptomorpha baetica, G. discolor, G. gracilis, G. kasparyani, and G. pectoralis are recorded from Turkey. Glyptomorhpa baetica is new to the Turkish fauna. It was reared from a new host Sesamia nonagrioides (Noctuidae, Lepidoptera) and was redescribed. Its diagnostic characters are illustrated. An identification key is provided for nine species of Glyptomorpha of Turkey and adjacent regions. Distribution of each species is added.     

Comparative analysis of genetic relationship and diagnostic markers of several taxa of Guizotia Cass. (Asteraceae) as revealed by AFLPs and RAPDs

Amplified fragment length polymorphism (AFLP) and random amplified polymorphic DNA (RAPD) were employed to examine the genetic relationship between Guizotia taxa, to suggest the taxonomic status of some of these taxa, and to identify their diagnostic markers. Results from AFLPs and RAPDs share some features in common, both revealing G. scabra ssp. schimperi as the most closely related taxon to G. abyssinica, and indicating that G. arborescens and G. zavattarii are the most divergent taxa. Most of the diagnostic markers revealed in this study were specific to G. arborescens and G. zavattarii. Our analysis suggests that G. scabra ssp. scabra, G. scabra ssp. schimperi, Chelelu and Ketcha are separate species. In this study, AFLP was found to be superior to RAPD in detecting genetic variation, in internal consistency of the data and in the fitness of its clusters to genetic similarity data. AFLPs revealed genetic relationship between Guizotia taxa that is more inline with the cytogenetic and hybridization studies than that revealed by RAPDs.     

Novelties in Adenia (Passifloraceae): Four new species, a new combination, a vegetative key, and diagnostic characters for known Madagascan species

Four new species and one new combination ofAdenia are presented, along with a vegetative key and diagnostic characters of the Madagascan species. Additional notes are provided about unusual specimens and field observations.Adenia kigogoensis from Tanzania is shown to be distinct fromA. stenodactyla (its putative closest relative) andA. digitata based on anther connation and other floral traits. The remaining new taxa are from Madagascar.Adenia litoralis has been observed from one coastal locality in northern Madagascar. It is distinctive in fruit size and leaf form.Adenia metamorpha is the only Madagascan taxon with a narrow cylindrical trunk and large napiform tuber; it is also known from only one locality in Madagascar in the Ankarana Reserve.Adenia mcdadiana is a robust liana with highly reduced glands and leaves that appear to be neotenic compared to its closest putative relative,A. sphaerocarpa. Finally, the position ofA. stylosa has been clarified. This species was once treated asA. firingalavensis var.stylosa, and prior to that asA. epigea var.stylosa, but molecular and morphological data suggest it is separate from these species.     

Ceratomyxa (Myxozoa: Bivalvulida): Robust taxon or genus of convenience?

The genus Ceratomyxa (Myxozoa: Myxosporea: Bivalvulida) contains parasites that typically infect the gall bladders of marine teleosts. Species of this genus have also been recorded from elasmobranchs, while the best known species (Ceratomyxa shasta) is a systemic pathogen of fresh water salmonid fishes. Here we characterise 10 new species of Ceratomyxa from marine teleosts using morphometric and rDNA sequence data. A phylogeny of all Ceratomyxa species for which ssrDNA sequence is available was estimated by parsimony, maximum likelihood and Bayesian analyses. Mapping host fish taxonomy, geographic locality and morphology onto the phylogenetic tree provided some concordance of these characters to groups of Ceratomyxa species, but in no case was it consistent throughout the inferred phylogeny. The position of C. shasta as a sister species to the Ceratomyxa clade contradicts previous estimates of marine myxozoan phylogeny which suggested C. shasta was an unrelated lineage. Comparative DNA sequence data is available for more than 17% of some 200 described Ceratomyxa species and the genus now represents one of the most cohesive lineages within the Myxozoa. The independent branching of all atypical Ceratomyxa species and Palliatus indecorus, indicates a review of the diagnostic characters and possible division into more genera is warranted when further data are available.     

A new species of Acanthosyris (Santalaceae) from Bolivia and a key to the woody South American Santalaceae

Acanthosyris asipapote, a new species from the vicinity of Santa Cruz, Bolivia, is described and illustrated. It is most similar to A. paulo-alvinii Barroso, known only from the state of Bahia, Brazil, but differs by leaf characters, pilose filaments, and smaller seeds. A key to the five woody genera and nine species of Santalaceae in South America is provided. Cervantesia, Jodina, and Myoschilos are probably monotypic; Santalum (in South America) has a single species, and Acanthosyris has five species.     

中国单格孢属（丝孢纲）的种

报道单格孢属的两个新种,一个新组合,5个中国新记录种和两个未定名种,同时,对所有已知在中国发现的本属真菌的种进行了归纳总结并制作了检索表。新种小黑球单格孢Monodictys nigraglobulosa的典型特征是产生黑色近球形的分生孢子,具有黑而厚的隔膜;横向单格孢Monodictys transversa的分生孢子横向生长,即孢子的横向量度大于其高度。两个未定名种具有单格孢属的特征,但目前的材料所表现的分种特征还不够充分,暂称之为Monodictys sp.1和 Monodictys sp.2,供进一步研究探讨。新组合为方单格孢Monodictys quadrata (Atk.) G. Z. Zhao & T. Y. Zhang。研究标本保存在山东农业大学植物病理学标本室（HSAUP）。
