Three species of the Acanopsilus Kieffer, 1908, six species of Acanosema Kieffer, 1908, two species of Polypeza Förster, 1856, and four species of Psilomma Förster, 1856 of the Russian fauna are reviewed, keyed and illustrated. Six of these species are described: Acanopsilus comadensis sp. n. (Russia: Primorsky krai), A. minimus sp. n. (Russia: Primorsky krai), Acanosema (Cardiopsilus) dentigastrum sp. n. (Russia: Primorsky krai), A. (C.) epicnemium sp. n. (Russia: Primorsky krai) A. (C.) setigerum sp. n. (Russia: East Siberia, Yakutia; Sweden), Psilomma calaris sp. n. (Russia: Kunashir Island; Japan). The generic status of Cardiopsilus Kieffer, 1908 is reduced to subgeneric one under Acanosema Kieffer, 1908 and a new combination is proposed for A. productum (Kieffer, 1908), comb. n. from Cardiopsilus Kieffer, 1908.

The Face

A new genus of melitturgine bees (Panurginae: Melitturgini) is described and figured from central Saudi Arabia. Belliturgulanajdica Engel, gen. et sp. n., is similar in several respects to the genus Flavomeliturgula Patiny in that both have a greatly elongate glossa that is longer than the face and is truncate apically. The former differs in the greatly elongate and flattened first labial palpomere, the remaining palpomeres unmodified, the greatly protuberant clypeus, and long labrum lacking dense setal patches, among other traits. In addition, remarks are made on the composition of Flavomeliturgula, with Meliturguladeserta Warncke (Iran, Pakistan), removed to Khuzimelissa Engel, gen. n., resulting in the new combination Khuzimelissadeserta (Warncke), comb. n.Khuzimelissa differs from Flavomeliturgula by the unmodified labial palpomeres (lacking the elongate first three labial palpomeres of the latter genus), the acute glossa (broadly truncate in the latter), glossa shorter than head length (greater than head length in the latter), the abundant, white, squamiform setae of the mesoscutum (sparse, erect setae in the latter), cleft pretarsal claws (simple in the latter), presence of metasomal setal bands (lacking in the latter), and apically emarginate pygidial plate (acutely rounded in the latter). The species of Flavomeliturgula are organized into three subgenera, including Koreshomelissa Engel, subgen. n., and Freyamelissa Engel, subgen. n., and these may eventually warrant generic status once phylogenetic work on the tribe has been completed. A key to the Arabian genera of Panurginae is provided, along with an augmented key to the genera of subtribe Meliturgulina.

The snakefly genus Amurinocellia (Raphidioptera: Inocelliidae) is recorded from China for the first time. Two species are described as new to science: Amurinocellia sinica sp. nov. and Amurinocellia australis sp. nov. A new combination, Amurinocellia calida (H. Aspöck & U. Aspöck) comb. nov. is proposed. A key is provided for the species of Amurinocellia. The generic status and the zoogeography of Amurinocellia are discussed.

A New Species

The generic status of Winitia Chaowasku (Annonaceae Juss., Miliuseae Hook.f. & Thomson) is reaffirmed by an extensive phylogenetic reconstruction using seven plastome regions (matK, ndhF, rbcL, ycf1 exons; trnL intron; psbA-trnH, trnL-trnF intergenic spacers) and including, among others, seven accessions of Winitia plus two accessions of its sister group, Stelechocarpus Hook.f. & Thomson. The results disclosed a maximally supported clade of Winitia, as well as of Stelechocarpus. The sister relationship of the two genera is still rather poorly supported and the branch uniting them is very short, whereas the branches leading to Winitia and to Stelechocarpus are relatively long, corresponding to their considerable morphological differences. Additionally, in Miliuseae there is a particular indel of eight continuous base pairs in the trnL-trnF intergenic spacer potentially diagnostic for generic discrimination, i.e., members in the same genus possess the same indel structure (absence or presence of a gap), and this indel differentiates Winitia from Stelechocarpus. Winitia cauliflora (Scheff.) Chaowasku appears polyphyletic and Winitia longipes (Craib) Chaowasku & Aongyong comb. nov. based on Stelechocarpus longipes Craib is consequently proposed. Furthermore, our phylogenetic data support a new species, Winitia thailandana Chaowasku & Aongyong sp. nov. from southern Thailand, which is described and illustrated. A key to genera in the sageraeoid clade (Sageraea-Winitia-Stelechocarpus) and a key to the four species of Winitia are provided.

Abstract Lectotypes of Cneorhinus viridimetallicus Motschulsky, 1860, C. cuprescens Motschulsky, 1866, C. nodosus Motschulsky, 1860, and Dermatodes carinulatus Motschulsky, 1866 are designated. A new synonymy Catapionus viridimetallicus (Motschulsky, 1860) (= Cneorhinus cuprescens Motschulsky, 1866, syn. n.) and a new combination Scepticus carinulatus (Motschulsky, 1866), comb. n. are established. New data on the morphology of some genera of the tribes Cneorhinini and Tanymecini are presented. The record of Amystax fasciatus Roelofs, 1873 for Kunashir Island is shown to be based on misidentification of Scepticus carinulatus.

The concept of the jumping spider genus Pochytoides Berland & Millot, 1941 is reviewed, based on the examination of described and undescribed species. Pochytoides is elevated from the subgeneric to the generic rank and a short diagnosis and description of the genus are presented. Redescriptions or descriptions of all species are provided together with a key to the species. Two new combinations are proposed: Pochytoides perezi (Berland & Millot, 1941) comb. nov. and P. poissoni (Berland & Millot, 1941) comb. nov. (both from Pochyta). Pochyta remyi Berland & Millot, 1941 originally placed in the subgenus Pochytoides is excluded; new combination Thiratoscirtus remyi (Berland & Millot, 1941) comb. nov. is proposed for it (but its generic status is uncertain). Six new species are described: Pochytoides monticola sp. nov., P. obstipa sp. nov., P. lamottei sp. nov., P. patellaris sp. nov., P. securis sp. nov. and P. spiniger sp. nov. The genus has a West African distribution.

A new species of Satyrinae butterfly, Faunula dubii n. sp., is described from southern Patagonia in Chile and Argentina.Its affinities with other species of the genus Faunula C. & R. Felder are evaluated, and its distribution and habitat arediscussed. A new combination Faunula euripides n. comb., and a new synonymy are proposed, Punargenteus penaiHayward n. syn. of Satyrus gustavi (Staudinger). Generic status of Chillanella stelligera (Butler) is reconsidered. All the species of Satyrinae occurring in southern Patagonia are listed.

The size, shape and surface morphology of human erythrocytes (RBC) were examined by scanning electron microscopy (SEM), of the fixed material directly and by transmission electron microscopy (TEM) of surface replicas to compare the relative merits of these two observational procedures for this type specimen.A sample of human blood was fixed in glutaraldehyde and washed in distilled water by centrifugation. The washed RBC's were spread on freshly cleaved mica and on aluminum coated microscope slides and then air dried at room temperature. The SEM specimens were rotary coated with 150Å of 60:40- gold:palladium alloy in a vacuum evaporator using a new combination spinning and tilting device. The TEM specimens were preshadowed with platinum and then rotary coated with carbon in the same device. After stripping the RBC-Pt-C composite film, the RBC's were dissolved in 2.5N HNO3 followed by 0.2N NaOH leaving the preshadowed surface replicas showing positive topography.

Main Factors

Russian economy has reached the low level of inflation, but economic growth has not accelerated. Moreover, according to official forecasts, in the following years it will still be low. The article concludes that domestic demand, which is one of the main factors of growth, is significantly constrained by monetary, budgetary and fiscal spheres. The situation in the Russian economy is still hampered by the decline of the world economic growth. The prospects of financial markets are highly uncertain. This increases the possibility of crisis in the world. Leading countries widely use non-traditional measures to support their economies in the similar environment. In the world economy as well as in Russia a principally new combination of factors has emerged, which create specific features of economic growth. It requires special set of measures to stimulate such growth. The article proves that Russian regulators have large unused potential to stimulate growth. It includes monetization, long-money creation, budget and tax stimuli. It is important that the instruments, which will be used, should be based on domestic mechanisms. This will strengthen financial basis of the economy and may encourage economic growth. Some specific suggestions as to their use are made.
