Description of Careproctus guillemi n. sp. (Pisces: Scorpaeniformes) from Weddell Sea

Careproctus guillemi differs from the other Careproctus species in the following combination of characters: pectoral fin rays 22 (11 + 4+7); pectoral girdle with three round radials (1 + 0+ 1 + 1); mouth oblique and maxillary extending beyond posterior edge of eye. Relationships between C. guillemi and C. longipectoralis are provided. The endochondral pectoral girdle of C. longipectoralis is described for the first time.     

New Australian butterfly genus Jameela gen. nov. (Lepidoptera: Lycaenidae: Polyommatinae: Polyommatini) revealed by morphological, ecological and molecular data

This paper proposes to split the Australian Polyommatini genus Erysichton Fruhstorfer, 1916 into two genera on the basis of molecular, morphological and early stage behavioral attributes. The utility of reflective eye pattern as a taxonomic character is discussed and a neotype of Lycaena lineata Murray, 1874 is designated.     

A revision of the Dip lop salts group of dinoflagellates (Dinophyceae) based on material from the British Isles

SEM has made possible a detailed re-examination of the thecal plates of marine dinoflagellates belonging to the Diplopsalis group which have been collected in an extensive survey of the seas around the British Isles. Six genera are recognized: Diplopsalis, Diplopsalopsis, Dissodium, Oblea, Zygabikodinium and die new genus and species Boreadinium pisiformis Dodge 8c Hermes. The confused taxonomic history of the group is discussed, the valid species are listed and a key for the identification of the genera is given.     

Biodiversity and conservation of yeasts

In the framework of initiatives, aiming at a better definition of biodiversity in microorganisms and of its role in ecosystem function, the biology of yeasts is revisited with particular emphasis on their ecology and classification. The limited number of different species isolated from, as well as the exceedingly low yeast cell counts in, most natural environments are discussed and possible explanations presented. The impact of the use of molecular taxonomic techniques of classification on the extent of biodiversity within yeasts is also debated, as well as the possible repercussions of more aggressive pre-isolation treatments of samples.     

A Propos D'observations Sur L'ultrastructure Du Cilié Cyrtolophosis Mucicola Stokes, 1885

RESUME L'étude détaillée du cortex et des organelles buccaux de Cyrtolophosis mucicola montre que ce Cilié possède une organisation structural corticale comparable à celle de Woodruffia, Platyophrya, Kuklikophrya et des Colpoda . Tout en restant conforme au plan général d'organisation de ces derniers, il a des variations spécifiques décelées au niveau des organelles buccaux qui confirment la position de C. mucicola dans la famille des Cyrtolophosididae , incluse dans le sous-ordre des PLATYOPHRYINA.     

Meloidogyne hispanica n. sp. (Nematoda: Meloidogynidae), the 'Seville Root-Knot Nematode'

Meloidogyne hispanica n. sp. is described and illustrated from specimens obtained from peach rootstock, Prunus persica silvestris Batsch, from the Seville district of Spain. The perineal pattern of the female is oval shaped to rectangular with low dorsal arch and often widely spaced lateral lines with fringe-like striae. The stylet, 14.1 μm long, has broad, distinctly set off knobs. Males have a high, rounded head cap that slopes posteriorly. Labial disc and medial lips are fused to form elongate lip structures. The robust styler, 23.5 μm long, has large, rounded knobs that are slightly set off from the shaft. Mean second-stage juveniles length is 392.6 μm. The truncate head region is generally not annulated. The distinctly rounded and raised labial disc and the crescent-shaped medial lips form dumbbell-shaped lip structures. The stylet, 11.1 μm long, has rounded, posteriorly sloping knobs. The slender tail, 46.4 μm long, has large irregular-sized annules in the posterior region and ends in a bluntly rounded tip. Tomato was a good host; tobacco, pepper, and watermelon were poor hosts; cotton and peanut were nonhosts. Meloidogyne hispanica n. sp. reproduces by mitotic parthenogenesis and has a somatic chromosome number of 2n = 33-36. The esterase pattern is unique among Meloidogyne species.     

Taxonomic revision of the genus Jassidophaga Aczél (Diptera: Pipunculidae) in Korea

In this paper, three Korean species of the big‐head fly, genus Jassidophaga Aczél were treated: J. chiiensis (Ouchi), J. pala (Morakote) and J. villosa (Roser). Of these, J. pala is reported in Korea for the first time. A key to Korean species and photographs on external features are given.     

Historical and recent evidence for close relationships among Rickettsia parkeri,R. conorii,R. africae,and R. sibirica: Implications for rickettsial taxonomy

Rickettsia parkeri, a member of the spotted fever group rickettsias, was first described in 1939 and was thought to be non‐pathogenic until recently, when it was found to cause a spotted fever‐like illness in humans and areas of necrosis (eschars) at the sites of tick bites. Accordingly, there is currently much interest in this emerging pathogen. In this study, all published articles concerning R. parkeri were reviewed and analyzed for evidence of relatedness among this agent and other spotted fever group (SFG) rickettsiae which also produce similar clinical syndromes and/or eschars, including R. conorii, R. africae, and R. sibirica. A synthesis of the historical (antigenic) and recent (molecular) data supporting a phylogenetic sub‐grouping of these SFG organisms is presented and comments are offered about the taxonomy of rickettsial organisms in general, and R. parkeri in particular.
