Puparia, immatures and adults of a new whitefly genus and species, Himalayaleyrodes sarcococcae Dubey are described from the Western Himalaya, India. The new species was found feeding on leaves as well as on green stems of Sarcococca saligna (D. Don) Muell. Biological information, habitus, line arts, photomicrographs of holotype and Scanning Electron Microscope (SEM) images are given for this new taxon. Also, we discuss similarities and dissimilarities of puparia of the new genus with its closely related genus Bemisia Quaintance & Baker. Feeding behaviour is discussed.

The genus chiton Loricella is revised. It comprises nine species. Two of these species, L. neoguinensis n. sp. and L. solomonensis n. sp., are described as new. Based on the analysis of morphological features studied using a scanning electron microscope, a revised diagnosis of the genus is provided. The characters diagnostic for this that distinguish it from the related genus Squamophora are as follows: a tubular hollow inside the dorsal scales, bristles on the dorsal side of the girdle, a wide ventral mouth region, a narrow mantle fold covered with simple longitudinally ribbed scales, smooth ventral scales, pits arranged in longitudinal rows in the central area of the tegmentum, and a bicuspid head of the major lateral teeth of the radula.

A new species, Nupela eremica sp. nov. is described from a high mountain lake located in the Eastern Range of Colombian Andes. The new taxon was studied from sediment and epiphyton samples and under light and scanning electron microscope. Comparison with morphologically similar taxa is showed. N. giluwensis, N. carolina, N. gomphosphenioides, N. encyonopsis, N. incerta, N. neglecta, N. tenuicephala, and N. exilissima show morphometric values overlapping those of Nupela eremica sp. nov. The combination of valve size and outline is unique and justifies the erection of this new species.

Alloperla Banks, 1906 (Plecoptera: Chloroperlidae) is a speciose genus of spring- and summer-emergent stoneflies known from the Oriental, eastern Palearctic, and Nearctic realms. Over 50 species are currently recognized. Alloperla clarki sp. nov. is described herein from the adult male stage from a small geographic area in the Appalachian Mountains in Virginia and West Virginia, USA. Diagnostic characters are presented with scanning electron microscope (SEM) photomicrographs. Alloperla clarki sp. nov. most closely resembles A. biserrata Nelson & Kondratieff, 1980, A. nanina Banks, 1911, and A. stipitata Surdick, 2004. These four species share similar characteristics of the male epiproct and appear to comprise a species group. The Alloperla nanina Group is formally proposed. Comparative SEM images are also provided for A. biserrata, A. nanina, and A. stipitata to assist with differentiating between these four species.

A New Species

Light and electron microscope observations show that a brackish diatom taxon should be classified as a new species of a new genus; Pseudofrustulia lancea gen. et sp. nov. We propose separating Pseudofrustulia from other similar genera such as Frickea, Frustulia, Amphipleura, Muelleria, and Envekadea on the basis of its thickened axial ribs, raphe endings, axial costae, morphology of helictoglossa, size of striae on valve surfaces, and areolae on the inner side between its axial ribs and raphe. Girdle bands may be another diagnostic feature for the separation of Pseudofrustulia from related taxa, but more detailed observations using SEM images are required to determine if bands are diagnostic.

A new genus, Grahamstoneia Melika & Nicholls, gen. nov., with one new species, G. humboldti Melika & Nicholls, sp. nov., asexual generation, is described. This new taxon occurs in the south-western Nearctic, inducing galls on two species within Quercus section Protobalanus (Q. vacciniifolia Kellogg and Q. chrysolepis Liebm.), an ecology and distribution shared with the closely related genus Heteroecus Kinsey.

Large collections of Australian Syllidae (Polychaeta) from the Australian Museum (Sydney) have been examined and identified, together with material from the Hamburgische Zoologische Museum der Universität (Hamburg, Germany), as well as some specimens from other museums. All known Australian species of the subfamily Syllinae belonging to Inermosyllis San Martín, 2003 (1 species), Megasyllis n. gen. (3 species), Opisthosyllis Langerhans, 1879 (5 species), and Trypanosyllis Claparède, 1864 (2 species), are described and figured. The Scanning Electron Microscope was used to illustrate relevant taxonomic characters and reproduction methods in these genera. Inermosyllis pseudohaploides is described as a new species. Megasyllis is described as a new genus, including M. corruscans (Haswell, 1885) and M. heterosetosa (Hartmann-Schöder, 1991) from Australia, and M. inflata (Marenzeller, 1879) from Japan and Australia; thespecies M. multiannulata (Aguado, San Martín & Nishi, in press) from Japan is also referred to this genus. The genus Inermosyllis is reported for the first time from Australia, as well as the species Opisthosyllis longicirrata Monro, 1939 and Trypanosyllis aeolis Langerhans, 1879.

Bromodesmus catrionae n. gen., n. sp. (type species), B. militaris n. sp., B. riparius n. sp. and B. rufus n. sp. are described. The new genus is characterized by greatly reduced paranota and a gonopod telopodite expanded at the distal end into a posteriorly concave hood fringed with teeth; the hood partly protects a long, curved, acutely pointed solenomerite. Male leg setation in the type species of six Tasmanian dalodesmid genera is briefly discussed and illustrated with scanning electron micrographs. The sphaerotrichome shaft is sharply pointed in Atrophotergum; gently tapered in Dasystigma, Lissodesmus and Tasmanodesmus; expanded at the tip in Bromodesmus; and entirely absent in Gasterogramma. Tips of the setae forming the dense ventral brush on male podomeres are gently tapered in Dasystigma and Lissodesmus, truncated in Gasterogramma, expanded in Bromodesmus and forked in Tasmanodesmus.

Abstract. A very distinctive new deep-photic coccolithophore is described from the NE Indian Ocean. The new species is trimorphic with: 200–300 body coccoliths bearing low spines attached by narrow stems to a basal narrow-rimmed placolith structure; up to 18 circum-flagellar coccoliths with tall sail-like spines; and up to 22 coccoliths with moderately elevated spines occurring both around the circum-flagellar coccoliths and antapically. These features make the coccolithophore unique and require placement in a new species and genus. The basal structure, however, shows similarities to a recently recognized group of narrow-rimmed placoliths. Hence, the new coccolithophore provides some support for this grouping as a significant addition to our understanding of coccolithophore biodiversity, and potentially an explanation for a set of anomalous molecular genetic results. In addition the new taxon provides further evidence that the deep-photic coccolithophore community is more diverse than has been assumed.

Cathode Reduction

Porous silicon (PSi) was fabricated by using electrochemical anodic etching method. Then acid treatment and cathode reduction treatment were employed to improve the luminescence properties and stability of PSi material. Photoluminescence (PL) measurements and scanning electron microscope (SEM) were used to observe the luminescence properties and microstructure of samples, respectively. The results of PL measurements showed that the PL intensity and the stability of luminescence of samples after cathodic reduction and acid treatment were significantly improved. The SEM images showed that the porosity of PSi may be increased through the cathodic reduction treated.
