Contribution to the knowledge of the weevil genus <Emphasis Type="Italic">Otiorhynchus</Emphasis> Germ. (Coleoptera,Curculionidae) from Turkmenistan and adjacent territories

Data on 15 species of the subgenus Pseudotiorhynchus Magnano, 2004 of the genus Otiorhynchus Germar, 1822 from Kazakhstan, Turkmenistan, and Iran are given. Otiorhynchus lukarevskayae Davidian, sp. n., O. karakalensis Davidian et Savitsky, sp. n., O. konstantini Davidian et Savitsky, sp. n., O. muratovi Savitsky et Davidian, sp. n., O. kopetdagicus Savitsky et Davidian, sp. n., and O. shakhensis Savitsky et Davidian, sp. n. from Turkmenistan, and O. khorasanus Savitsky et Davidian, sp. n. from Iran are described as new to science. A new synonymy is established: Pseudotiorhynchus Magnano, 2004 = Crassorhynchus Magnano, 2004, syn. n. Otiorhynchus iranensis Magnano, 2004 is transferred from the subgenus Protarammichnus Voss, 1960 to the subgenus Pseudotiorhynchus. Lectotype of O. conicirostris Stierlin, 1886 is designated. A key to 15 species of the subgenus Pseudotiorhynchus is given. The new subgenus Microhanibotus Savitsky et Davidian, subgen. n. is established for the new species O. ghilarovi Davidian et Savitsky, sp. n. from the Western Kopet Dagh in Turkmenistan. Microhanibotus subgen. n. is closely related to the subgenera Pseudotiorhynchus, Hanibotus Reitter, 1912 and Nubidanus Reitter, 1912.     

The Position of the Palaeozoic Genus <Emphasis Type="Italic">Tunguskagyrus</Emphasis> Yan,Beutel et Lawrence in the Family Triaplidae sensu n. (Coleoptera,Archostemata: Schizophoroidea)

Re-examination of the late Permian Tunguskagyrus planus Yan, Beutel et Lawrence, 2018 has shown that it does not belong to the family Gyrinidae (Adephaga) but should be placed in the family Triaplidae sensu n. (Archostemata) as a congener to “Triaplus” sibiricus Volkov, 2013 (Tunguskagyrus sibiricus (Volkov, 2013), comb. n.). Both these Palaeozoic species, in contrast to the Triassic members of Triaplus Ponomarenko, 1977, have no large metacoxal femoral plates and, therefore, would be better placed apart from the Mesozoic representatives of Triaplus (in a different genus). The synonymy of the family names Triaplidae Ponomarenko, 1977 (= Catiniidae Ponomarenko, 1968, syn. n., nom. praeocc., non Catiniidae Bocquet et Stock, 1957 (Crustacaea, Copepoda), = Coleocatiniidae Ponomarenko et Prokin, 2015, syn. n.) is established. Thus, the family now comprises Avocatinus Ponomarenko, 1969, Catinius Ponomarenko, 1968, Catinoides Ponomarenko, 1969, Macrocatinius Ponomarenko, 1969, Triaplus Ponomarenko, 1977, Triassocatinius Ponomarenko, 1969 and Tunguskagyrus Yan, Beutel et Lawrence, 2018.     

To the knowledge of the <Emphasis Type="Italic">Sphecodes hyalinatus</Emphasis> Hagens species-group (Hymenoptera,Halictidae)

Five species of the hyalinatus species-group of the genus Sphecodes Latreille 1804 (Hymenoptera, Halictidae) are reviewed. Sphecodes maruyamanus Tsuneki and S. murotai Tsuneki are found in Russia for the first time, and S. hyalinatus Hagens is newly recorded from the Kuril Islands (Kunashir). Illustrated keys to males and females of all the species of the S. hyalinatus species-group are provided. An updated checklist of 37 species of the genus Sphecodes is given.     

New data on the taxonomy of ground-beetles (Coleoptera,Carabidae) from Palaearctic Asia

Synonymy of two genus-group names is substantiated: Tricholicinus Poppius, 1912 (type species: Tricholicinus setosus J.R. Sahlberg, 1880) = Martyr Semenov et Znojko, 1929 (type species: Martyr praeteritorum Semenov et Znojko, 1929), syn. n. and Psammodromius Peyerimhoff, 1927 (type species: Psammodromius noctivagus Peyerimhoff, 1927) = Xanthomelina Iablokoff-Khnzorian, 1964 (type species: Apristus zajtzewi Eichler, 1924), syn. n. Synonymy of the following names of the species-group taxa is established: Calosoma (Callisthenes) elegans (Kirsch, 1859) = C. (Callisthenes) declive (Dohrn, 1884), syn. n., lectotype of the latter is designated; Carabus (Semnocarabus) erosus erosus Motschulsky, 1866 = C. (Semnocarabus) erosus karascharensis (Eidam, 1931), syn. n., lectotype of the latter is designated; C. (Semnocarabus) cicatricosulus pseudoerosus Mandl, 1955 = C. (Semnocarabus) bogdanowi semnocosulus Deuve et Tian, 2013, syn. n.; Chlaenius (Dinodes) viridis (Ménétriés, 1832) = Ch. pallidicornis Ballion, 1871, syn. n.; Licinus (Tricholicinus) setosus (J.R. Sahlberg, 1880) = Licinus mongolicus Reitter, 1900, syn. n. = Martyr praeteritorum Semenov et Znojko, 1929, syn. n. = Martyr alter Semenov et Znojko, 1929, syn. n.; Psammodromius zajtzewi (Eichler, 1924), comb. n. (transferred from the genus Xanthomelina Iablokoff-Khnzorian, 1964) = Psammodromius pallidicolor (Mandl, 1973), syn. n. = Psammodromius damanabii Morvan, 1977, syn. n.Calosoma (Callisthenes) rostislavi Semenov, 1906, stat. resurr. is resurrected from synonyms of C. (Callisthenes) declive (Dohrn, 1884).     

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. The immunis and granulosus groups are downgraded to subgroups of the silphoides and fallax groups, respectively; the voriseki subgroup is transferred from the fallax to the fausti group. 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.).     

A review of scarabs of the subgenus <Emphasis Type="Italic">Nobius</Emphasis> Mulsant et Rey,genus <Emphasis Type="Italic">Aphodius</Emphasis> Illiger (Coleoptera,Scarabaeidae), of the fauna of Russia and neighboring countries

Scarab beetles of the subgenus Nobius Mulsant et Rey, genus Aphodius Illiger, distributed in Russia and neighboring countries are reviewed. A key to the species and notes on their biology are given. The three new synonymies are established: A. serotinus (Panz.),1799 = A. x-signum Reitter, 1892, syn. n.; A. gresseri Sem. 1898 = A. korgaldzhensis Nikolajev, 1987, syn. n.; A. chaldaeus Petr., 1971 = A. moreleti Baraud, 1980, syn. n.

A new subgenus and a new species of the tenebrionid genus <Emphasis Type="Italic">Leptodes</Emphasis> Dejean, 1834 (Coleoptera,Tenebrionidae)

The genus Leptodes was erected by Dejean (1834) for a single species, Sepidium boisduvalii Zubkoff, 1833, which is, consequently, the type species by monotypy. Kaszab (1959) established in Leptodes the subgenus Leptodinopsis based on the same type species, Sepidium boisduvalii. Thus the names Leptodes and Leptodinopsis are objective synonyms: Leptodes Dejean, 1834 = Leptodinopsis Kaszab, 1959, syn. n. A new subgenus Mesoleptodes G. Medvedev et Iljina subgen, n. (type species Leptodes semenowi Reitter, 1892) is established for species which Kaszab included in Leptodes s. str. A new species, Leptodes daghestanicus G. Medvedev et Iljina, sp. n., is described from Daghestan.     

Revision of the carabid genus <Emphasis Type="Italic">Meroctenus</Emphasis> Gemminger et Harold,with a new status of <Emphasis Type="Italic">Xenodochus</Emphasis> Andrewes (Coleoptera,Carabidae: Harpalini)

Originally described as a monotypical genus with unclear taxonomic position from Sudan, Meroctenus Gemminger et Harold, 1868 is treated as a polytypical genus of the Selenophori genus group with two subgenera: Meroctenus s. str. and Xenodochus Andrewes, 1941, stat. n. (the latter was previously considered a distinct genus). Within Meroctenus, two species are recognized: M. (Meroctenus) crenulatus Chaudoir, 1843 (type species) and M. (M.) mediocris (Andrewes, 1936), comb, n., transferred to Meroctenus s. str. from Xenodochus. A new subspecies M. (M.) crenulatus orientalis subsp. n. is described from Pakistan. Diagnoses of the genus Meroctenus in new interpretation as well as of its two subgenera are discussed, and a taxonomic review of the subgenus Meroctenus s. str. with a key to the species and subspecies is provided. The following synonymy is proposed: Meroctenus Gemminger et Harold, 1868 = Paregaploa Müller, 1947, syn. n.; Meroctenus crenulatus (Chaudoir, 1843) = Egaploa (Paregaploa) conviva Müller, 1947, syn. n. Lectotypes are designated for Ctenomerus crenulatus Chaudoir, 1843 and Xenodus mediocris Andrewes, 1936.     

New data on the taxonomy,distribution, and ecology of the weevil genus <Emphasis Type="Italic">Otiorhynchus</Emphasis> germar (Coleoptera,Curculionidae)

The subgenus Pocusogetus Rtt. of the genus Otiorhynchus Germ. is revised. The subgenus includes O. rosti Strl., O. shapovalovi Davidian et Yunakov, O. obsulcatus Strl., O. fischtensis Rtt., and O. gusakovi sp. n. closely related to O. fischtensis (both from Mt. Fisht, the Western Caucasus). O. fischtensis is transferred from the subgenus Vicoranius Rtt., its lectotype is designated. A key to species of Pocusogetus is given. The systematic position of the subgenera Pocusogetus and Vicoranius in the genus Otiorhynchus is discussed. New data on the geographical distribution and ecology of the little-known species of the subgenera Obvoderus Rtt., Pseudoprovadilus Magnano, and Clypeorhynchus Yunakov et Arzanov are given. Some features of ecological differentiation between Otiorhynchus species in the alpine and subalpine zones of the Caucasus are discussed.     

Taxonomy and Diversity of Freshwater Bivalve Mollusks (Bivalvia) of China (Based on Analysis of the Catalog by He and Zhuang, 2013)

The diversity of freshwater Bivalvia in China was assessed on the basis of critical analysis of original and published data on the fauna, morphology, taxonomy, and molecular genetics of this group. The taxonomic composition of the following genera has been considered in depth: Anemina Haas 1969, Cristaria Schumacher 1817, Sinanodonta Modell 1944, Lanceolaria Conrad 1853, Middendorffinaia Moskvicheva et Starobogatov 1973, Nodularia Conrad 1853, Unio Philipsson in Retzius 1788, Inversidens Haas 1911, Sphaerium Scopoli 1777, Pisidium Pfeiffer 1821, Odhneripisidium Kuiper 1962, and Euglesa Leach in Jenyns 1832 = Cyclocalyx Dall 1905. No fewer than 170 bivalve species were demonstrated to occur in the freshwater areas of China. Underestimation of the Bivalvia species abundance in previous studies, including the latest catalog of the Chinese Bivalvia (He and Zhuang, 2013), may be accounted for mostly by inadequate use of morphological methods and limited faunistic data, as well as a little number of taxonomic works supported by molecular data. Both the generic and specific compositions of the Chinese Unioniformes and Luciniformes have been significantly extended and updated. Based on a complex study of conchological characters, the following synonymy was established for three species: Sinanodonta qingyuani He et Zhuang 2013 = S. woodiana (Lea 1834) syn. n., Lanceolaria yueyingae He et Zhuang 2013 = L. eucylindrica C. Lin 1962 syn. n., Acuticosta jianghanensis He et Zhuang 2013 = Nodularia douglasiae (Griffith et Pidgeon 1833) syn. n.

Lectotypes for 74 nominal species and subspecies are designated.     

A review of encyrtid wasps (Hymenoptera,Chalcidoidea, Encyrtidae) of Macaronesia

The review contains an annotated list of 62 species of Encyrtidae from Macaronesia with data on their distribution, hosts, and use in biological control of agricultural insect pests. An attempt is undertaken to classify most of them according to nine types of ranges and to separate species which were introduced to Macaronesia by the ecesis, i.e., accidentally with their hosts. Three genera are synonymized: Acerophagus E.A. Smith, 1880 (= Pseudaphycus Timberlake, 1916, syn. n.); Isodromus Howard, 1887 (= Eupoecilopoda Erdös et S. Novicky, 1955, syn. n.); Syrphophagus Ashmead, 1900 (= Tassonia Girault, 1921, syn. n.). Cerchysiella togashii Tachikawa, 1988 is placed in the genus Zaommoencyrtus Girault, 1916. Cerchysiella koenigsmanni (Trjapitzin, 1985) is considered a subjective synonym of C. latiscapus (Shafee et Fatma, 1984). The following replacement names are given: Acerophagus xuzhihongi Trjapitzin, nom. n. for A. clavatus Xu Zhihong, 1999 non A. clavatus Pilipjuk, 1981; and Anagyrus sergueii Trjapitzin, nom. n. for Anagyrus orbitalis Timberlake, 1941 non A. orbitalis (Ruschka, 1923). Material on encyrtids from the Macaronesian islands Tenerife and Madeira in the museums in Madrid, Helsinki and Washington were examined.
