Pseudorchestes olgae sp. n. known only from the Dzhanybek Station is similar to P. abdurakhmanovi Korotyaev 1993 from Daghestan and southwestern Kazakhstan but differs in the narrower frons, sparse white scales on the frons and on the underside of the head, longer and narrower antennal club, less strongly curved hind tibiae, and larger size. Pseudorchestes tschernovi sp. n. from the Lower Volga River basin, Kazakhstan, and Kyrgyzstan differs from all known congeners, except for P. convexus sp. n. from Transaltai Gobi (Mongolia), in the strongly reduced wings that are only half as long as the elytra, and from the latter species, in the longer rostrum, paler antennae and legs, broad and apically excised scales on the elytra, and short, ovate antennal club in both sexes lacking dense velvety pubescence in male.10aPseudorchestes10aPseudorchestes abdurakhmanovi10aPseudorchestes convexus10aPseudorchestes olgae10aPseudorchestes tschernovi1 aKorotyaev, B.A.  uhttps://weevil.myspecies.info/new-species-weevil-genus-pseudorchestes-coleoptera-curculionidae-central-palaearctic02524nas a2200217   4500008004100000020001400041245013100055210006900186260000800255300001000263490000700273520174100280653002602021653002102047653001802068653002202086100002102108700002002129700002202149856013502171       2012                        eng d  a0044-513400aStratification and seasonal dynamics of the weevil (Coleoptera, Curculionoidea) assemblages in the Northern Caspian semidesert0 aStratification and seasonal dynamics of the weevil Coleoptera Cu  cJan  a58-700 v913 aIn 2003-2004, 102 species of five weevil families were found in the steppe and desert associations of the Caspian semidesert (Dzhanybek Station). Representatives of Curculionidae predominated. The majority of the commonest weevil species were most abundant (20) in the steppe associations, only 6 species were found in the steppe ones. The composition of the weevil community sharply changes during spring and summer. The greatest species richness (86 species) is observed in spring. Most of the species dominating in the herbage, both in the steppe and desert communities, are steppe polyphagous broad-nosed weevils with the daytime activity (Euidosomus acuminatus, Omias verruca, O. rotundatus, Phyllobius brevis); their majority are ephemeral species with short adult life. The soil surface layer is dominated by Temnorhinus strabus, Humeromima nitida, Mesagroicus poriventris, Archaeophloeus inermis, and Trachyphloeus amplithorax. In summer, 53 species of weevils are recorded; their numbers on the soil surface sharply drop, all abundant species being restricted to the herbage layer. Ecological characteristics of the steppe and desert weevil assemblages considerably change, and distinctions between these two types of assemblages increase. The correspondence between the characteristics of the vegetation and the dominant species composition is most evident in summer. Weevils feeding on intensely vegetating Medicago romanica (Stenopterapion tenue, Sitona spp., and Tychius spp.) achieve high densities in the steppe herbage; the core of the desert assemblages is formed by species associated with dominating chenopods (Metadonus anceps) and wormwoods (Ptochus porcellus) characterized by late and prolonged vegetation period.10aEuidosomus acuminatus10aOmias rotundatus10aOmias verruca10aPhyllobius brevis1 aKhruleva, O., A.1 aKorotyaev, B.A.1 aPiterkina, T., V.  uhttps://weevil.myspecies.info/stratification-and-seasonal-dynamics-weevil-coleoptera-curculionoidea-assemblages-northern-caspian-s02446nas a2200229   4500008004100000020001400041245014300055210006900198260000800267300001200275490000700287520161200294653002601906653002101932653001801953653002701971100002101998700002002019700002002039700002202059856013502081       2011                        eng d  a0044-513400aBeetles of the superfamily Curculionoidea (Coleoptera) in complex semi-desert in relation to climate change in the Northern Caspian region0 aBeetles of the superfamily Curculionoidea Coleoptera in complex   cMar  a311-3240 v903 aIn desert and steppe habitats of complex northern Caspian semi-desert, more than twofold differences in the number of species of the superfamily Curculionoidea dwelling in herbage (33 and 75 species, respectively) were found in the years of the "dry" (1972-1974) and "humid" (2003-2005) phases of climate change. The population numbers have changed in the majority of the species. Polyphagous steppe weevils of the subfamily Entiminae (Otiorhynchus velutinus, Euidosomus acuminatus, Omias verruca, O. rotundatus) with spring activity of adults have retained their positions in the community least varied. These species were the main dominants of the spring communities both in the 1970s and 2000s. Nearly all of the weevils that changed their numbers since the 1970s belong to specialized herbivores with the maximum adult activity in summer. In the more humid 2000s, the abundance of some desert-steppe weevils dominating the desert communities (Phacephorus nebulosus, Metadonus anceps and, particularly, Ptochus porcellus) dropped drastically. The largest part of the weevils that increased their numbers most strongly (Phyllobius brevis, Trachyphloeus amplithorax, Archaeophloeus inermis, Stenopterapion tenue, Sitona mops, S. longulus, Tychius spp.) are associated with Medicago romanica, the plant that considerably raised its population density in the microdepressions during the "humid" phase. The data show an evident reduction of the most xerophilic (desert-steppe) components of the weevil fauna and an increase of the proportion of mesophilic species. These changes seem to show a cyclic pattern.10aEuidosomus acuminatus10aOmias rotundatus10aOmias verruca10aOtiorhynchus velutinus1 aKhruleva, O., A.1 aChernov, Yu, I.1 aKorotyaev, B.A.1 aPiterkina, T., V.  uhttps://weevil.myspecies.info/beetles-superfamily-curculionoidea-coleoptera-complex-semi-desert-relation-climate-change-northern-c01116nas a2200157   4500008004100000020001400041245010000055210006900155260000800224300001200232490000700244520054400251100002100795700002100816856012100837       2011                        eng d  a0044-513400aSeasonal dynamics of damage of small-leaved lime trees by phylophagous phyllophagous arthropods0 aSeasonal dynamics of damage of smallleaved lime trees by phyloph  cMay  a552-5580 v903 aSeasonal dynamics of damage of small-leaved lime (Tilia cordata) trees by phylophagous arthropods was monitored in Izhevsk during the period from 1999 to 2002.
