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.

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 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.

Among the many interesting Homoptera which have been sent to me by Professor E. H. Strickland is a series of an unusual Delphacodes collected at Cooking Lake, Alberta. This distinct little species is described at this time in order to stimulate further collection of these inconspicuous but interesting insects from western Canada, where there must be many more new species as yet unrecorded.

A new species of Cyrtodactylus is described from the Truong Son (Annamite mountain range) of Quang Binh Province in central Vietnam. It is characterized by 3–5 transversal dorsal bands between the limb insertions, a neckband reaching the posterior margin of eye, 19–20 irregular longitudinal rows of dorsal tubercles, forelimbs with tubercles, 47–50 longitudinal rows of ventrals at midbody, 9–11 precloacal pores in an angular series in males and 16–27 enlarged precloacal scales in both sexes, 20–23 lamellae below the 4th toe, a segmented tail, and lacking of a distinct ventrolateral fold, a precloacal groove and femoral pores, as well as transversally enlarged subcaudal plates. The new species is known only from the karst forests of Phong Nha - Ke Bang National Park. Preliminary data on its natural history are provided.

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. Key words: turbellarian systematics, Proseriata, Monocelididae, Ectocotyla, crab commensal

The genus Pseudocapritermes Kemner, 1934, endemic to Oriental region is represented by 18 species. A new species, Pseudocapritermes kunjepu Mathew sp. nov. (Isoptera, Termitidae, Termitinae), is described from Kerala, India, based on the characters of soldiers and workers. Morphological measurements of the soldiers and workers are given with suitable illustrations. A revised key to the species of Pseudocapritermes (based on soldier caste) found in India along with the species distribution map are also provided. Key words: Isoptera, new species, Pseudocapritermes, Termitidae

The genus Aspidistra (Asparagaceae) shows strong variation of flower groundplan. We add further evidence of this variation describing a new species, Aspidistra paucitepala from southern Vietnam that has flowers with 2-4 tepals, 2-4 stamens and a gynoecium with unilocular ovary. Bisexual flowers with three tepals and three stamens are extremely rare among monocots with biotic pollination. Compared with typical trimerous pentacyclic monocot flowers, they can be either interpreted as trimerous and tricyclic or as 1.5-merous (at least in perianth and androecium) and pentacyclic. Both interpretations imply floral features unusual for ‘higher’ Asparagales. Aspidistra paucitepala resembles recently described A. brachystyla from northern Vietnam in narrow funnel-shaped to nearly tubular perianth with very small lobes and short cylindrical pistil with stigma located below the level of anthers. As species of the taxonomically diverse genus Aspidistra are frequently observed in the field without reproductive structures and cannot be properly identified, a need for DNA barcoding approach is obvious. We present preliminary data showing that plastid psbA-trnH and nuclear 5S-NTS regions could be useful for DNA barcoding of Aspidistra.

Solenocentrum oblongum from southern Peru is described and illustrated, representing the first record of this genus for the country. It is similar to Bolivian S. lueri, but can be distinguished by its oblong, sub-pandurate labellum (vs. triangular to sagittate) with rounded base (vs. sagittate), glabrous margins (vs. densely ciliate) and slender oblong calli (vs. broadly ovate). Line drawings of labellum outlines and an identification key to the four accepted species of Solenocentrumare provided. Key Words: Andes, Bolivia, Cusco, Pseudocentrum, Solenocentrum lueri
