A new species of the weevil genus <Emphasis Type="Italic">Otiorhynchus</Emphasis> germ., subgenus <Emphasis Type="Italic">Dibredus</Emphasis> Rtt. (Coleoptera,Curculionidae: Entiminae), from Southeastern Turkey

Otiorhynchus schuberti sp. n. (subgenus Dibredus Reitter, 1912) is described from Kahramanmara? Province in Southeastern Turkey. It is closely related to O. nudiformis Reitter, 1914 and, less closely, to O. rufimanus Hochhuth, 1847, but differs from both in a small bidentate tooth on the fore femur.     

A review of the <Emphasis Type="Italic">merkli</Emphasis> group of the weevil genus <Emphasis Type="Italic">Plinthus</Emphasis> (Coleoptera,Curculionidae)

The merkli group of the weevil genus Plinthus is revised. Plinthus navarsati Davidian et Savitsky, sp. n. is described from Northeastern Turkey. New data on the morphology and geographical distribution of P. merkli Frivaldszki, 1894, P. cavazzutii Meregalli, 1985, and P. latipennis Meregalli, 1985 are given, with a key to all the four species of the merkli group.     

A review of the <Emphasis Type="Italic">Chrysolina lineella</Emphasis> species-group of the subgenus <Emphasis Type="Italic">Anopachys</Emphasis> Motschulsky, 1860, genus <Emphasis Type="Italic">Chrysolina</Emphasis> Motschulsky, 1860 (Coleoptera,Chrysomelidae, Chrysomelinae)

The Chrysolina lineella species-group of the subgenus Anopachys Motschulsky, 1860 is revised. Chrysolina watanabei Takizawa, 1970 is revalidated from the synonymy with Ch. lineigera (Jacobson, 1901). Ch. sundukovi Mikhailov, 2006 is a new junior synonym of Ch. watanabei. Special attention is paid to the infraspecific variability of the male and female genitalia. The structure of the aedeagal flagellum and the spermatheca are used as diagnostic characters. A key to species is included. Ch. watanabei is for the first time recorded from the Asian continent (Primorskii Territory of Russia and Northeastern China).     

First records of the weevil <Emphasis Type="Italic">Otiorhynchus smreczynskii</Emphasis> Cmoluch, 1968 (Coleoptera,Curculionidae: Entiminae) in the Republic of Belarus

The first records of the weevil Otiorhynchus smreczynskii Cmoluch, 1968 from the Republic of Belarus are reported. Its trophic specialization in the region is considered, and photographs of the adult on a leaf of the host plant and the leaves of various hosts damaged by the weevil are provided.     

On an introduced weevil <Emphasis Type="Italic">Polydrusus formosus</Emphasis> (Mayer) (Coleoptera,Curculionidae: Entiminae) in the Summer Garden,St. Petersburg

In the summer of 2015, Polydrusus formosus was found in the Summer Garden, St. Petersburg on Tilia cordata in the trellises and berceau restored in 2011. This weevil was known in the European part of the former USSR only in Moldova and Crimea. The finding of 6 individuals of Polydrusus formosus only on the linden trellises may be due to an unintended introduction of the weevils (probably only a single fertilized female) with the plants from Germany and maintenance of the population in the Summer Garden for already five years.     

Review of the <Emphasis Type="Italic">granulosus</Emphasis> Subgroup of the Weevil Genus <Emphasis Type="Italic">Plinthus</Emphasis> (Coleoptera,Curculionidae)

A review of the fauna of the subgenus <Emphasis Type="Italic">Troginus</Emphasis>, genus <Emphasis Type="Italic">Carpelimus</Emphasis> (Coleoptera,Staphylinidae), from tropical Africa

The review includes seven species, three new species are described: Carpelimus maliensis, C. neuterus, and C. xenosus spp. n. The names Trogophloeus variegatus Cameron, 1944, T. ruandanus Cameron, 1956, and Carpelimus maroccanus Gildenkov, 2004 are synonymized with Carpelimus atomus (Saulcy, 1864). Carpelimus rondaensis is downgraded to the subspecies C. boops rondaensis (Fagel, 1957). Lectotype of Trogophloeus dundoensis Cameron, 1950 is designated. New data on the morphology and distribution of Carpelimus (Troginus) species are given.     

New species of the weevil genus <Emphasis Type="Italic">Pseudorchestes</Emphasis> (Coleoptera,Curculionidae) from the central Palaearctic region

Three new species of the genus Pseudorchestes Bedel are described. Pseudorchestes olgae sp. n. known only from the Dzhanybek Research Station is similar to Ps. 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 tibia, and larger size. Pseudorchestes tschernovi sp. n. from the Lower Volga River basin, Kazakhstan, and Kyrgyzstan differs from all the known congeners, except for Ps. convexus sp. n. from the Trans-Altai Gobi (Mongolia), in the strongly reduced wings which are only half as long as the elytra, and from the latter species, in the longer rostrum, paler antennae and legs, wide and apically excised scales on the elytra, and in the antennal club short and ovate in both sexes and lacking dense velvety pubescence in the male.     

A new species of <Emphasis Type="Italic">Polygala</Emphasis> subgenus <Emphasis Type="Italic">Hebeclada</Emphasis> (Polygalaceae) from central Brazil

Polygala pauciramosa, a new species from the Federal District and the state of Goiás is described, illustrated, and compared with related species of Polygala subgenus Hebeclada.

Evaluation of <Emphasis Type="Italic">Nastus fausti</Emphasis> Reitter (Coleoptera: Curculionidae: Entiminae: Nastini) for biological control of invasive giant hogweeds (<Emphasis Type="Italic">Heracleum</Emphasis> spp.)

The weevil Nastus fausti Reitter (Coleoptera, Curculionidae) was evaluated for its potential in the biological control of invasive giant hogweeds (Heracleum spp.). Quantitative sampling suggested that at a high population density (more that 3–4 mature larvae per plant) damage by N. fausti larvae could have some negative impact on the above-ground part of the plant. However, no-choice laboratory tests showed that N. fausti females were able to feed on a number of Apiaceae genera, including such important cultivated crops as carrot, parsnip, and celeriac. Feeding on these plants did not cause any significant decrease in female survival or fecundity. Moreover, at least part of N. fausti larvae may feed and develop on roots of these plants, and the rate of their growth and development does not differ significantly from that in larvae fed on roots of H. mantegazzianum. N. fausti adult and larval feeding on Angelica purpurascens, representative of related genus of the same tribe, was recorded under natural conditions, too. In combination, these data suggest that N. fausti is an oligophagous species connected with plants from at least several genera of Apiaceae and thus it cannot be considered a potential agent for biological control of invasive Heracleum species.

Keys to the subgenera and to the species of the subgenus Pseudapoderites are given. The genus Deporaus, subgenera Pseudapoderites and Japonodeporaus, and four species are redescribed. The distribution of these species in Russia is discussed.     

New Data on the Taxonomy of the Weevil Subgenus <Emphasis Type="Italic">Caucasoplinthus</Emphasis>, Genus <Emphasis Type="Italic">Plinthus</Emphasis> (Coleoptera,Curculionidae)

The taxonomic composition of the subgenus Caucasoplinthus Davidian, 1995 is revised.

Plinthus attilai Davidian et Savitsky, sp. n. and P. ljudae Davidian et Savitsky, sp. n. are described from Turkey and Abkhazia, respectively. New data on the taxonomy, distribution, and ecology of some little-known species are presented. The following new synonymy is established: Molytes vittatus Motschulsky, 1839 (= Meleus irroratus Reitter, 1884, syn. n., = Meleus faldermanni Faust, 1884, syn. n., = Meleus difficilis Faust, 1884, syn. n.).
