A New Species

Dwayaangam heterospora is described as a new Hyphomycete attacking the eggs of rotifers and nematodes. The fungus attaches to the eggshell by an appressorium-like swelling. After penetration a postinfection bulb is produced from which haustorium-like assimilative hyphae develop and consume the contents of the egg. The fungus produces several morphologically different types of conidia from inconspicuous conidiogenous cells. The conidia are solitary, hyaline and septate and are either scolecospores or staurospores. Key words: egg parasite, rotifers, Dwayaangam, Triposporina, aquatic hyphomycetes.

Odontepyris costatus sp. nov. is described from Japan and Taiwan. This new species is most similar to O. formosicola Terayama, 1997 known from Cambodia and Taiwan according to the key to the Eastern Palaearctic Odontepyris. O. costatus sp. nov. can be distinguished from the latter by the relatively small eye and the wide metapectal-propodeal disc. It is also similar to O. telortis Lim & Lee, 2009 known from South Korea, but it is distinguished from O. telortis by the imbricate median area of metapostnotum. The morphological variations and diagnostic characters of the Eastern Palaearctic species are briefly discussed and the modified key to species is provided. Key words: new species, Japan, Taiwan, wing venation

A New Species

A new species in the Hyphomycete genus Phialocephala is described. The new species Phialocephala virens produces an intense greyish green to turquoise colour on certain media and has smaller conidia, shorter phialides, and shorter conidiophores than previously described Phialocephala species. Its tolerance to low levels of the antibiotic cycloheximide suggests the fungus may have affinities with species of Ophiostoma. Cultures of the fungus cause a bright green stain when inoculated onto sapwood of some conifers. Key words: Phialocephala virens, new species, Hyphomycetes, sapstain.

A New Species

Classiculasinensis, isolated from decaying leaves from Mozigou, Chongqing Municipality, China, is described as a new species. The new species is a member of basidiomycetous aquatic hyphomycetes which represent a small proportion of all aquatic hyphomycetes. This species falls within the genus Classicula (Classiculaceae, Pucciniomycotina) and is closely related to C.fluitans, based on multiple gene sequence analyses. Morphologically, it is characterised by the apical, hyaline, obclavate or navicular conidia with several hair-like lateral appendages and by its holoblastic and monoblastic conidiogenesis, with a flat un-thickened conidiogenous locus. Clamp connections and haustorial branches were often observed in culture.

A New Species

The study of material collected during routine monitoring surveys dealing with oil extraction and aquaculture in waters off Myanmar (North Andaman Sea) and in the Gulf of Thailand, respectively, allowed us to analyse the taxonomy and diversity of the polychaete genusTerebellides(Annelida). Three species were found, namelyTerebellidescf.woolawa,Terebellides hutchingsaespec. nov.(a new species fully described and illustrated), andTerebellidessp. (likely a new species, but with only one available specimen). The new species is characterised by the combination of some branchial (number, fusion and relative length of lobes and papillation of lamellae), and thoracic (lateral lobes and relative length of notopodia) characters and is compared with all species described or reported in the SW Indo-Pacific area, as well as with those sharing similar morphological characteristics all around the world. The taxonomic relevance of the relative length of branchial lobes and different types of ciliature in branchial lamellae for species discrimination in the genus is discussed. A key to allTerebellidesspecies described in SE Indo-Pacific waters is presented.

AbstractTelenomus reynoldsi n. sp. (Scelionidae: Telenominae) is described as an egg parasite of Geocoris punctipes Say and G. pallens Stål in California. The parasite has been recovered from cotton fields at Thermal and Indio, and from strawberry fields at El Toro, California. Additional material deposited in the U.S. National Museum of Natural History has been recovered from Geocoris collected at Buttonwillow and Weed, California.

Mallomonas gusakovii sp. nov. is described from Vietnam based on silica-scale morphology studied by means of transmission and scanning electron microscopy. This species belongs to section Quadratae and is characterized by large and broad scales of three types with an internal reticulation, V-shaped rib and a forward projecting wing. Different types of the V-shaped rib in taxa from section Quadratae are discussed. Scales of Mallomonas gusakovii were found only in two sites in Phu Quoc Island, Southern Vietnam.

A New Species

The microbial population in the rhizosphere of wheat, oats, alfalfa, and peas was studied and the relative abundance of different types of micro-organisms recorded. By means of the plating method it was found that bacteria and actinomycetes were 7 to 71 times greater in the rhizosphere than in the soil distant from the roots, whereas fungi were but 0.75 to 3.1 times more numerous.Different varieties of plants affected the activity of the various groups of soil micro-organisms differently. Thus fungi were more numerous in the rhizosphere of oats, and bacteria in the rhizosphere of alfalfa. Seventeen genera of fungi were represented in isolates from the rhizosphere of seedlings and the soil distant from the roots. However, no marked difference was observed in the types isolated from the rhizosphere of different varieties of seedlings. A fungus isolated from the rhizosphere of alfalfa proved to be a new species and the genus Spicularia Persoon was amended to include it.

Egg Capsule

Ectocotyla hirudo (Levinsen, 1879) is redescribed and recorded for the first time from the gills and branchial chambers of Chionoecetes opilio and Hyas araneus. Problems arising from previous descriptions are resolved through comparison of freshly collected material, at different times of the year, with type material of Coleophora sp. and the type material of E. paguri Hyman, 1944, both of which are shown to be identical to the present material. Accordingly, E. paguri Hyman, 1944 is regarded as a junior synonym of E. hirudo (Levinsen, 1879). A new species, E. multitesticulata, is described and recorded also from C. opilio and H. araneus. Ectocotyla multitesticulata differs from E. hirudo primarily in the larger size of the worm, the greater number and size of the testes, the size of the egg capsule, and in the differences of the karyotype. The genus Ectocotyla is discussed in relation to closely related genera (Peraclistus, Minona, and Preminona) in the family Monocelididae.
