A New Species

The interaction and reaction of PCl3 and PCl3-H2S mixtures with the microporous materials Silicalite, ALPO-5, NaY, NaX, and NaA have been investigated, with the intention of producing phosphorus sulfide clusters in the pores. A rich chemistry was observed and monitored by solid state 31P NMR. The presence of P4S3, α-P4S5, β-P4S6, and P4S7 inside the NaY α-cages was demonstrated, as well as a new species that is possibly a third geometric isomer of P4S4 with C3v symmetry. 129Xe NMR showed the exclusion of Xe from the micropores by the phosphorus sulfides. Sulfides lower than P4S7 are small enough that they undergo rapid pseudo-isotropic reorientation inside the NaY α-cage. Key words: phosphorus sulfides, intrazeolitic cluster synthesis.

A New Species

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.

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.

AbstractEquimolar mixtures of 3,5-dimethylpyrazole (1) with four NH-imidazoles (2–5) have been studied by13C and 15N CPMAS NMR and by DSC. In three cases, the solid mixture behaves as the sum of the individual components [imidazole (2), 2-methylimidazole (3) and 2,4(5)-dimethylimidazole (5)]. In one case [4,5-dimethylimidazole (4)], the mixture corresponds to a new species in which the dynamic behavior of1 no longer exists.

A New Species

The new species Penicillium kananaskense is described based on an isolate from soil in a Pinus contorta forest from Alberta, Canada. Colonies are characterized by their relatively rapid growth, velutinous texture, white to slightly pink conidial masses, growth at 5 °C, and absence of growth at 37 °C. The conidiophores are monoverticillate or have one metula, are up to 300 μm tall, smooth walled or with slightly roughened walls, vesiculate, and bear ampulliform phialides, 8–11.5(−14.5) × 2.5–4 μm, that produce disordered chains of ellipsoidal conidia, 3–5 × 2.5–4 μm, with smooth or finely roughened walls. The species is compared with previously described taxa and its subgeneric affinities are discussed. Preliminary data on the many secondary metabolites produced by the ex-type culture are presented. Key words: Penicillium kananaskense, soil, Pinus contorta var. latifolia, mycotoxins.
