Despite their ecological and economic importance, hymenopteran parasitoids are severely understudied. Even in countries with a long taxonomic history such as Germany, dating back to the 18th century and including prolific figures like Christian Gottfired Nees von Esenbeck and Otto Schmiedeknecht, those species-rich groups are seldom the subject of comprehensive research efforts, leaving their true diversity unknown. This is often due to their small size of a few millimetres on average, leading to difficulties in their identification and examination. The chalcidoid family Pteromalidae is no exception to this neglect. So far, 735 species have been reported from Germany. Estimating the diversity of this group is not possible, but it has to be assumed that many more species are still to be discovered in Germany. With this study, we improve the knowledge on pteromalid diversity and present new records of 17 genera and 41 species, previously unknown to occur in Germany. We also match and describe previously unknown sexes of two species, based on DNA barcode data. The results of this study were generated as part of the German Barcode of Life Project. The newly-recorded species are illustrated and notes on the biology and distribution are given. The ecological significance of Pteromalidae and potential value as indicators for nature conservation efforts are briefly discussed.

Der Beitrag untersucht den Zusammenhang von Reflexivität und Medialität (das, was ein Medium zum Medium macht), indem er die Idee der Reflexion an den konkreten Formen von Spiegelungen in Literatur und Film wie zum Beispiel Doppelgänger oder Figurenspaltungen darstellt. Dabei zeigt sich, daß jedes Medium autoreflexiv verfasst ist und daß die Vorstellung von Subjektivität seit dem 18. Jahrhundert selbst auf diesem Zusammenspiel von Reflexivität und Medialität beruht. Das Subjekt gilt demnach als reflexiver Effekt der Medialität, wie es an einer Betrachtung von Foucaults berühmter Meninas-Interpretation nachverfolgt werden kann.<br><br>This article analyses the relation between reflexivity and mediality (what makes a medium a medium) by presenting concrete situations of optical and specular reflections in literature and film, such as doubles (Doppelgänger) and split figures. Thus it can be shown that since the 18th century every medium is self-reflexive and that the concept of subjectivity has its basis in the interplay of reflexivity and mediality. The subject is an effect of medialitity as may be demonstrated by a new recapitulation of Foucault’s famous Meninas-interpretation.

The article is devoted to the analysis of the concept of literary romanticism. The research aims at a refinement of the “romanticism” concept in relation to the history of the literary process. The main research methods include conceptual analysis, textual analysis, comparative historical research. The author analyzes the semantic genesis of the term “romanticism”, various interpretations of the concept, compares the definitions of different periods and cultures. The main results of the study are as follows. The history of the term “romanticism” shows a change in a number of definitions for the same concept in relation to the same literary phenomena. By the end of the 20th century, realizing the existence of significant contradictions in the content of the term “romanticism”, researchers often come to abandon it. At the same time, the steady use of the term “romanticism” testifies to the subject-conceptual component that exists in it, which does not lose its relevance, but just needs a theoretical refinement. Conclusion: one have to revise an approach to romanticism as a theoretical concept, based on the change in the concept of an individual in Europe at the end of the 18th century. It is the newly discovered freedom of an individual predetermines the rethinking for the image of the author as a creator and determines the artistic features of literary romanticism.

Spaces are conditioned by social conditions; on the other hand, social structure is affected by spaces. Arcades, the subject of this article, first appeared in Europe in the 18th century as a result of an increase in trading activities. The arcades in Ankara, which were started to be built in the 1950s together with increasing trading activities, contributed to the urban economy with intense activities of shopping, re-determined social and urban relations as essential places of everyday life and became distinctive urban buildings with their original building typologies and the function of maintaining public continuity in the area of private ownership. Aim: This study aims to study the process in which passages emerged and to analyze their spatial features and, in particular, to examine the spatial formation of the distinctive passages in Ankara on the basis of their causation. Method: In the article, spatial features of the passages in the West were mentioned, and the conditions of the period in which the passages in Ankara were built were briefly explained. Spatial analysis of the passages found in the research area were conducted, and the formation of these passages were analyzed together with their reasons. Results: Of the 31 arcades in Ankara, 27 were built between 1950 and 1980 on and around the Atatürk Boulevard in Yenişehir/Kizilay. As of the mid-1950s, new planning decisions which were made one after the other in the built-up area re-shaped the Boulevard and its surrounding as the existing buildings were demolished, allowing to construct new buildings with arcades or stores in their entrances. Their interior designs and connections to the streets are different from the arcades in the West. Conclusion: The present subdivision system and new planning decisions applied in property order shaped the passages which were peculiar to Ankara.

Several stink bugs in the subfamily Pentatominae are crop pests or have the potential to damage plants of economic importance. In the Brazilian state of Rio Grande do Sul, where agriculture plays a major role in the economy, the knowledge about pest stink bugs is fragmented and, in some instances, outdated. This work provides a summary of Pentatominae species recorded in Rio Grande do Sul feeding on the four most important grain crops for the state, i.e. soybean, rice, maize, and wheat, plus canola, an emerging crop. This survey is enhanced with new records from scientific collections, a short diagnosis for each species, distribution maps, an identification key, and carefully illustrated to allow for species recognition in the field. With this work, we aim to reunite the scattered knowledge of the group in one single revision, and provide a useful tool for identifying the pest stink bugs of Rio Grande do Sul.

In the 18th century, as many as 300 German-language plays were produced with the military and its contact and friction with civil society serving as focus of the dramatic events. The immense public interest these plays attracted feeds not least on the fundamental social structural change that was brought about by the establishment of standing armies. In his historico-cultural literary study, Tilman Venzl shows how these military dramas literarily depict complex social processes and discuss the new problems in an affirmative or critical manner. For the first time, the findings of the New Military History are comprehensively included in the literary history of the 18th century. Thus, the example of selected military dramas – including Lessing's Minna von Barnhelm and Lenz's Die Soldaten – reveals the entire range of variety characterizing the history of both form and function of the subject.

The subject of the article is the vocabulary of Polish criminals from the 18th century. The author reached for a press release from 1778. This press release is one of the oldest credentials of the Polish criminal jargon. The text describes a court hearing and only mentions the existence of specific communication style between villains that the court had to face. The news from “Gazeta Warszawska” contains eighteen lexemes. The author of this article discusses these words – he indicates the etymology of these jargonisms and presents a continued existence of the vocabulary in Polish (in the 19th and 20th centuries). Some remarks on the provenance of jargon terms may raise doubts among readers. The author is aware of this. However, he considers it significant to bend over the form and semantics of the accumulated vocabulary – researchers often refer to this press release from the 18th century, but do not focus on the history of the vocabulary of Polish criminals.

This article engages in the new concept of individual happiness that spread in the 18th Century and in Goethe’s pivotal novel Wilhelm Meisters Lehrjahre (1795–96). In this novel, the process of “Bildung” is designed to lead the protagonist to happiness, but happiness turns out to be possible only if the process can be governed from the outside, by powers alien to the subject. For this reason, the article argues that the notion of happiness orchestrated in the novel is not based on a revolutionary concept of happiness or a victorious Enlightenment critique, but on a concept derived from a more local field of knowledge, namely “Polizeywissenschaft”. Central to German state reform, and the practices of local administration in the late 18th Century, “Polizeywissenschaft” was developed in order to render happiness to both states and individuals, and it did so by means of surveillance and secret intervention in everyday life. On a theoretical level, the breakthrough of ”the police” during the century could be mapped as an outcome of the transition from a sovereign power regime to a biopolitical one, in Michel Foucault’s teminology. In Wilhelm Meisters Lehrjahre, as in the biopolitics encoded in the “Polizeywissenschaft,” the experience of happiness is thus coupled with a new way of governing life as such.

Статья посвящена истории развития словарного дела на Руси и появлению первых словарей. Затрагиваются первые, несловарные формы описания лексики в письменных памятниках XI–XVII вв. (глоссы), из которых черпался материал для собственно словарей. Анализируются основные лексикографические жанры этого времени и сложение на их основе азбуковников. В статье уделено внимание таким конкретным лексикографическим произведениям, как ономастикону «Рѣчь жидовскаго «зыка» (XVIII в.), словарям-символикам «Толк о неразумнех словесех» (XV в.) и «Се же приточне речеся», произвольнику, объясняющему славянские слова, «Тлъкование нεоудобь познаваεмомъ въ писаныхъ рѣчемь» (XIV в.), разговорнику «Рѣчь тонкословія греческаго» (ХV в.). Характеризуется словарь Максима Грека «Толкованіе именамъ по алфавиту» (XVI в.). Предметом более подробного освещения стал «Лексис…» Л. Зизания – первый печатный словарь на Руси. На примерах дается анализ его реестровой и переводной частей. Рассматривается известнейший труд П. Берынды «Лексикон славеноросский и имен толкование», а также рукописный «Лексикон латинский…» Е. Славинецкого, являющий собой образец переводного словаря XVII в. The article is dedicated to the history of the development of vocabulary in Russia and the emergence of the first dictionaries. The first, non-verbar forms of description of vocabulary in written monuments of the 11th and 17th centuries (glosses), from which material for the dictionaries themselves were drawn, are affected. The main lexicographical genres of this time are analyzed and the addition of alphabets on their basis. The article focuses on specific lexicographical works such as the «Zhidovskago» (18th century) the dictionaries-symbols of «The Talk of Unreasonable Words» (the 15th century). and «The Same Speech», an arbitrary explanation of slavic words, «The tlution of the cognition in the written», (the 14th century), the phrasebook «Ry subtle Greek» (the 15th century). Maxim Greck's dictionary «Tolkien names in alphabetical order» (16th century) is characterized. The subject of more detailed coverage was «Lexis...» L. Sizania is the first printed dictionary in Russia. Examples give analysis of its registry and translation parts. The famous work of P. Berynda «Lexicon of Slavic and Names of Interpretation» and the handwritten «Lexicon Latin...» are considered. E. Slavinecki, which is a model of the 17th century translated dictionary.

Chloropidae are of major economic importance, since the larvae of some species are pests of cereals and grasses, some are parasitoids and predators, and adults of some Hippelates spp. visit and transmit or are suspected of transmitting yaws sores in man and animals and by feeding around the eyes are vectors of Brazilian Purpuric Fever. Within the framework of the exploration of the biodiversity of Diptera in Southwest Saudi Arabia a survey of the grass flies fauna in 18 sites in Jazan, Asir, and Najran in south-western Saudi Arabia was performed mainly using Malaise traps and sweep nets from 2010– to 2016. Sixty six species of 43 genera and three subfamilies of Chloropidae were identified and are recorded from Saudi Arabia, 20 of them for the first time and three are described as new species: Elachiptera arabica Deeming sp. n.; Kwarea ismayi Deeming sp.n. and Tricimba turneri Deeming sp.n.. This makes the total number of Chloropidae species in Saudi Arabia 95 (including 29 species previously recorded). Seventy images are presented. The species of Chloropidae listed are predominantly of Afrotropical/ Palaearctic origin. An updated checklist of Chloropidae species of Saudi Arabia is presented.This study adds new records of Chloropidae to the Saudi Arabian Diptera fauna, which will become reference points for research detailing the systematic geographic distribution and for identifying other specimens submitted for identification. Further species will undoubtedly be discovered with more research involving collecting and rearing methods.

Abstract This review aims to present advances in studies on the propagation of the Annonaceae species, which includes species of economic importance such as: soursop, custard apple, atemoya and cherimoya. In sexual propagation, advances are mainly related to a better understanding of the stages of seed development, dormancy mechanisms, and germination. In asexual propagation, compatibility studies between grafts and rootstocks are presented, focusing on the expression of genes involved in tissue formation. The cutting method is also discussed, which is another option for the propagation for this group of plants considered difficult to root, approaching endogenous and exogenous factors related to the subject, as well as management strategies that affect the success of this technique.
