Biology of xylophilous larvae of the rhagionid flies <Emphasis Type="Italic">Chrysopilus dives</Emphasis> and <Emphasis Type="Italic">Chrysopilus nigrifacies</Emphasis> (Diptera,Rhagionidae)

The larval morphology and biology of two species of rhagionid flies (Diptera, Rhagionidae) from the Russian Far East are described for the first time. Larvae of Chrysopilus dives Loew develop in the tunnels of xylobiont insects in the trunks of ash trees. Larvae of Ch. nigrifacies Nagatomi were found under the bark of the elm, Sakhalin cork tree, birch, and fir. Morphological characteristics of larvae of Chrysopilus are discussed.     

The Larvae of Three Species of Jewel Beetles of the Subgenus <Emphasis Type="Italic">Chrysoblemma</Emphasis> Jakovlev, 1889, Genus <Emphasis Type="Italic">Sphenoptera</Emphasis> Dejean, 1833 (Coleoptera,Buprestidae), from Turkmenistan

The larvae of three species of jewel beetles of the subgenus Chrysoblemma Jakovlev of the genus Sphenoptera Dejean are described: Sphenoptera (Ch.) tamarisci beckeri Dohrn reared from Horaninovia ulicina Fisch. et Mey., Atriplex tatarica L. and Salsola arbuscula Pall.; Sphenoptera (Ch.) tomentosa Jakovlev from Salsola arbuscula; Sphenoptera (Ch.) amplicollis Jakovlev from Salsola orientalis S.G. Gmel. and Halothamnus glaucus (Bieb.) Botsch. Differential diagnoses to distinguish them from the previously described sphenopterine larvae are given.     

Little known leaf beetles of the genus <Emphasis Type="Italic">Chrysolina</Emphasis> (Coleoptera,Chrysomelidae) from China

Chrysolina (Semenowia) chalcea (Weise, 1889), Ch. (Pezocrosita) cyanopurpurea (Ballion, 1878), and Ch. (Chrysocrosita) fuyunica Chen, 1961 are redescribed. A male (topotype) of Ch. cyanopurpurea was examined for the first time. Ch. belousovi Lopatin, 2000 is a new junior synonym of Ch. cyanopurpurea; Ch. bienkowskii Lopatin, 2000 is a new junior synonym of Ch. chalcea. The taxonomic position of all the taxa mentioned is discussed.     

A new species,a new synonym,and new records of the hover-fly genus <Emphasis Type="Italic">Cheilosia</Emphasis> Meigen (Diptera,Syrphidae)

A new species, Cheilosia richterae sp. n., is described in the nominotypical subgenus, being most closely related there to Ch. annulifemur Stackelberg, 1930. Two species, Ch. sootryeni Nielsen, 1970 and Ch. rufimana (Becker, 1984), are recorded from Russia for the first time. Ch. kuznetzovae Skufjin, 1977 is recorded for the first time from the Urals and western Siberia. The subgenus Nephocheila Barkalov, 2002 is synonymized with Nephomyia Matsumura, 1916. Figures of the male and female heads and the male genitalia are given for all the species.

A review of species of the subgenus <Emphasis Type="Italic">Taeniosticha</Emphasis> Motsch., genus <Emphasis Type="Italic">Chrysolina</Emphasis> Motsch. (Coleoptera,Chrysomelidae), distributed in the Dzungar Ata Tau and Tien Shan Mt. Ranges,with descriptions of two new species

Species of the subgenus Taeniosticha, genus Chrysolina, from the Dzungar Ala Tau, Northern and Central Tien Shan, are revised. A key to the species and figures of the aedeagus of each species are given. Two new species, Chrysolina klimenkoi sp. n. and Ch. sairannurica sp. n., are described from Southeastern Kazakhstan and Northwestern China. Two new species-groups are distinguished: the Ch. alatavica species-group distributed in the Dzungar Ala Tau and Boro-Khoro Mountain Ranges, and the Ch. tianshanica species-group with its members occurring in the Northern and Central Tien Shan. A scheme of the species distribution is given.     

Composition of the subgenus <Emphasis Type="Italic">Zeugotaenia</Emphasis>, genus <Emphasis Type="Italic">Chrysolina</Emphasis> (Coleoptera,Chrysomelidae), and examination of the nomenclatural types

Zeugotaenia Motschulsky, 1860 is resurrected as a valid name for the subgenus of Chrysolina with the type species Chrysomela limbata Fabricius, 1775. Diagnosis of the subgenus is compiled. Neotypes of Chrysomela limbata and Ch. limbifera Küster, 1846, and lectotypes of Chrysomela findelii Suffrian, 1851, Ch. hochhuthii Suffrian, 1851, and Ch. discipennis Faldermann, 1835 are designated. The types of Chrysomela limbata jenisseiensis Breit, 1920 and Chrysolina limbata kavani Bechyné, 1950 and the topotypes of Chrysomela limbata luigionii Depoli, 1936 are examined. Chrysolina furva Peyerimhoff, 1926 and Ch. dohrnii Fairmaire, 1865 do not belong to the subgenus Zeugotaenia.     

Composition and distribution of sibling species of <Emphasis Type="Italic">Chironomus</Emphasis> Meigen, 1803 (Diptera,Chironomidae) in Curonian Lagoon of the Baltic Sea

The species composition of Chironomus in the Curonian Lagoon has been investigated. It was shown that three sibling species of the plumosus group, namely, Ch. plumosus, Ch. balatonicus, and Ch. muratensis, and a first-generation interspecific hybrid Ch. muratensis × Ch. plumosus lived here. The occurrence frequency in the lagoon was 87, 19, 6, and 3% for Ch. plumosus, Ch. balatonicus, Ch. muratensis × Ch. plumosus, and Ch. muratensis, respectively. The species Ch. plumosus was recorded in all the areas (southern, central, and northern), while Ch. balatonicus was found only in the northern area in the village of Juodkrante near the city of Klaipeda. Presumably, the distribution of these sibling species is due to the presence of a salinity gradient in the lagoon.     

New leaf-beetle species (Coleoptera,Chrysomelidae) from China: IX

The following new species are described from Chinese provinces Gansu, Sichuan, and Yunnan, based on the material from the Zoological Institute, Russian Academy of Sciences, St. Petersburg, where the types are deposited: Zeugophora nigroaerea sp. n. (Zeugophorinae), Cryptocephalus pseudosplendens sp. n. (Cryptocephalinae), Chrysolina kippenbergi sp. n., Ch. irinae sp. n., Ch. sinica sp. n., Ch. nixiana sp. n., Ch. yunnana sp. n., Oreomela fulvicornis sp. n., O. multipunctata sp. n.

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).     

Findings of the leaf beetles <Emphasis Type="Italic">Chrysolina tundralis</Emphasis> and <Emphasis Type="Italic">Chrysolina roddi</Emphasis> (Coleoptera,Chrysomelidae) in the middle part of European Russia

Two species of leaf beetles, Chrysolina tundralis and Ch. roddi, were found in the “Galich’ya Gora” Nature Reserve (the middle part of European Russia), 1200 and 700 km, respectively, from the main part of the ranges of these species. Adults and larvae of Ch. tundralis feed on Lamium purpureum, those of Ch. roddi feed on Seseli intermedia there. Diagnostic characters of the adults of both species are reported.     

On Two Little Known Species of Leaf Beetles (Coleoptera,Chrysomelidae) from the South Urals

120 years ago G.G. Jacobson described two species of leaf beetles from the South Urals that have remained poorly studied until recently. Chrysolina roddi, previously known only from the foothills and low mountains of the South Urals, the low Zhiguli Mountains, and the limestone cliffs on the Don River, is recorded here for the first time from the alpine tundra of the Iremel massif; its host plant in the alpine zone is the small alpine lovage Pachypleurum simplex (= Ligusticum mutellinoides), family Apiaceae. Two species of the subgenus Crositops, Ch. roddi and Ch. kabaki, are presently treated as foothill-alpine disjunct taxa. The distribution of Ch. poretzkyi, described from the low-montane part of Bashkortostan, also shows a foothill-alpine disjunction. Alpine populations of Ch. poretzkyi are described here as a new subspecies Ch. (Arctolina) poretzkyi olschwangi Mikhailov subsp. n. Revision of the type of Ch. poretzkyi that has long been considered lost confirms that this species belongs to the subgenus Arctolina, in disagreement with its previous placement in the subgenus Pleurosticha. Within Arctolina, the identity of Ch. tundralis and its differences from Ch. poretzkyi are discussed.     

Host specificity of Asian <Emphasis Type="Italic">Chrysochus</Emphasis> Chevr. in Dej. (Coleoptera,Chrysomelidae: Eumolpinae) and their potential use for biological control of invasive <Emphasis Type="Italic">Vincetoxicum</Emphasis> species

Three Asian leaf beetles of the genus Chrysochus were investigated as potential biological control agents of Vincetoxicum rossicum and V. nigrum, invasive weeds in northeastern North America. Chrysochus chinensis and Ch. globicollis were collected from a field host in a different genus and subtribe. Preliminary no-choice laboratory tests with Ch. goniostoma showed that its physiological host range is too broad. Based on these data, we are not considering these three species as potential biological control agents of invasive Vincetoxicum species.     

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.     

Courtship song analysis in two hybrid zones between sibling species of the <Emphasis Type="Italic">Chorthippus albomarginatus</Emphasis> group (Orthoptera,Gomphocerinae)

Two new hybrid zones between sibling species of the Chorthippus albomarginatus group were described on the basis of the courtship song analysis. Not only the sounds emitted but also the accompanying stridulatory movements of the hind legs were analyzed, which allowed the temporal parameters to be classified in a more reliable way. One hybrid zone between Ch. albomarginatus and Ch. karelini was found in Ulyanovsk and Samara Provinces of Russia. The other hybrid zone, presumably between Ch. karelini and Ch. oschei, was found in the protected Askania-Nova steppe area in Kherson Province of Ukraine. Based on comparison of the natural and laboratory hybrids, a hypothesis on the structure and dynamics of the hybrid zones is proposed.     

New species of the buprestid genus <Emphasis Type="Italic">Endelus</Emphasis> Deyrolle (Coleoptera,Buprestidae) from China,India, and Laos

Endelus (Kubaniellus) indicus sp. n. from India, E. (K.) lao sp. n. and E. (K.) khnzoriani sp. n. from Laos, E. (s. str.) sausai sp. n. from China, and E. (s. str.) dembickyi sp. n. from India are described, the two latter species are included in the Endelus bicarinatus Théry, 1932 species-group recently established by the author. E. collinus Obenberger, 1922 is included in this group; lectotype of this species is designated. Keys to species of the subgenus Kubaniellus and of the E. collinus group are provided. E. (K.) kareni Kalashian is for the first time recorded for Shaanxi Prov., E. pacholatkoi Kalashian, E. smaragdinus Desc. et Vill., and E collinus Obenb., for Laos (the latter species, also for Myanmar).
