Terellia arailerica sp. n. – a new species of tephritid flies (Diptera: Tephritidae) from Armenia
The new species of tephritid flies Terellia arailerica sp. n. is described from Armenia (Arailer Mt.). A comparison of phalli of six similar species (T. virens (Loew, 1846), T. uncinata White, 1989, T. zerovae Korneyev, 1985, T. freidbergi V. Korneyev, 2013, T. ivannikovi V. Korneyev et Evstigneev, 2013 и T. odontolophi Korneyev, 1993) is given. These six species have (as well as the new one) entirely hyaline wings and they are associated with plants of the genera Centaurea Linnaeus, 1753 and Psephellus Cassini, 1826. The new species differs from mentioned above taxa in the extremely long tubular extension of glans of the phallus with filaments separating at the apex. The larvae of the new species feed on tissues of the capitula of Centaurea spectabilis (Fisch. & C.A. Mey.) Sch. Bip. and migrate into stem to pupate after feeding process. The migration from the capitulum into the stem depends on the rate of the capitulum drying process. When the capitulum is completely dry, larvae can be observed in the upper part of the stem. If the capitulum is not completely dry yet, larvae are located still inside i
First records of Urophora mauritanica Macquart, 1851 and U. merzi Mohamadzade Namin, 2011 (Diptera: Tephritidae) from Armenia
Urophora mauritanica Macquart, 1851 reared from Carthamus sp., and U. merzi Mohamadzade Namin, 2011 reared from Centaurea behen L. are recorded from Armenia for the first time. The first species was known from the Mediterranean region, Moldova, Ukraine, Russia, Azerbaijan, Kazakhstan, Uzbekistan and Iran. The second one was known only from Iran. Detailed illustrations of morphological characteristics of adults, along with the figures of host plants are presented in this paper
New records of Tephritidae (Diptera) from Armenia and Russia, with new data on the host plants
Two species of tephritid flies, Terellia odontolophi V. Korneyev, 1993 and Heringina arezoana Mohamadzade Namin et S. Korneyev, 2015 (Diptera: Tephritidae), are recorded for Armenia and Trascaucasia for the first time. The first species was additionally found in Saratov Region of Russia for the first time. Terellia odontolophi was previously known from Russia, the Ukraine and Iran, and H. arezoana from Turkey and Iran. The larvae of the first species develop in the capitula of Psephellus phaeopappoides (Bordz.) Wagenitz. (the new host plant for this species) in Armenia. The species Tephritis truncata (Loew, 1844) is widespread from the North Africa to Transcaucasia and its larvae develop in Leontodon spp. We registered a new host plant, Leontodon asperrimus (Willd.) Endl., for this species in Armeni
New data on the distribution and host plants of tephritid fies (Diptera: Tephritidae) from Armenia and selected regions of Russia
Urophora cuspidata (Meigen, 1826) and Tephritis nozarii Mohamadzade, 2012 are recorded for the frst time for Armenia, and the latter species for the frst time for Transcaucasia. Centaurea pseudoscabiosa glehnii (Trautv.) Wagenitz and Cousinia fedorovii Takhtajan are identifed as new host plants of Urophora cuspidata and Tephritis nozarii, respectively. First records for selected areas of Russia are presented: Urophora cardui (Linnaeus, 1758) for Samara Region and Mordovia, U. cuspidata for North Ossetia, Mordovia and Samara Region, Oxyna favipennis (Loew, 1844) for Nizhny Novgorod Region and Mordovia, O. parietina (Linnaeus, 1758) for Mordovia, Merzomyia westermanni (Meigen, 1826) for Saratov Region
Hetero-association of aromatic molecules in aqueous solution
Knowledge of the physical chemistry of small molecules complexation (the hetero-association) in aqueous solution is increasingly important in view of the rapidly emerging branch of supramolecular chemistry dealing with the formation of heterogeneous polymeric structures having specific functional roles. In this paper, the 50-year history of scientific studies of hetero-association of heterocyclic aromatic molecules in aqueous solution has been reviewed. Some important correlations of structural and thermodynamic parameters of complexation have been reported based on large data-set of hetero-association parameters accumulated to date. The fundamental problem of ‘energetic composition’ of π-stacking is extensively discussed. The review has shown that there are some gaps in our understanding of heteroassociation, which provides a challenge for further studies in this are
Revision of the Terellia virens Group (Diptera, Tephritidae) with Description of Three New Species
The Terellia virens group includes eight species of uniformly greenish flies with white setulose abdomens and hyaline wings, variable in the characters of the male and female terminalia. Three new species are described and illustrated: Terellia freidbergi sp. n. from Middle and Near East, from flower heads of Centaurea behen L., T. ivannikovi V. Korneyev et Evstigneev, sp. n. from European Russia, Kazakhstan and Uzbekistan, breeding in flower heads of Ce. chartolepis Greuter, and T. whitei V.?Korneyev et Mohamadzade, sp. n. reared from flower heads of Cousinia spp. in Kazakhstan, Kyrgyzstan, Turkmenistan and Iran. Illustrated diagnoses or redescriptions of other species and a key to the species of Terellia with hyaline wings and white setulose abdominal tergites are given.Группа Terellia virens включает в себя 8 видов однообразно зеленоватых мух с прозрачными крыльями и беловолосистым брюшком, отличающихся строеним гениталий самцов и самок. Описаны Terellia freidbergi sp. n. со Среднего и Ближнего Востока, выведенная из соцветий Centaurea behen?L., T. ivannikovi V.?Korneyev et Evstigneev, sp. n. из Европейской России, Казахстана и Узбекистана, развивающейся в соцветиях Ce. chartolepis Greuter, и T. whitei V. Korneyev et Mohamadzade, sp. n. связанная с соцветиями Cousinia spp. в Казахстане, Кыргызстане, Туркменистане и Иране. Представлены также иллюстрированные переописания других видов и определительная таблица видов рода Terellia c прозрачными крыльями и беловолосистыми тергитами брюшка
