Adults of the family Simuliidae have been known in Europe for a very long time as very serious pests affecting both men and cattle, and there were many interesting legends, even up to the middle of the eighteenth century, explaining their origin from grottos in the mountains (Tömösváry). Fabricius (1784) for the first time found a Simulium pupa (probably that of S. venustum Say) and described it under the name Tipula sericea, but to Schönbauer (1795) we owe the discovery that the earlier stages (egg, larva and pupa) of Simulium (Kolumbatczer-Mücke) are to be found in running water.

Globba wengeri (C.E.C. Fisch.) K.J. Williams, former state flower of Mizoram, a rare and critically endangered plant species, commonly known as ‘dancing girl’, belonging to the family Zingiberaceae, is reported in this communication for the first time from Serchhip District in Mizoram at an elevation of about 1187 m a.s.l. It was found on moist, watery and rocky slopes. The plant is under severe threat in the natural habitat and therefore, further studies are required to determine life history and particular survival threats of this species.

Nine species of the genus Galaxias and one species of the genus Paragalaxias are found to be represented in Tasmania. The taxonomy, meristic and morphometric variation of each species is examined and data on the distribution, life history and ecology are presented together with references and synonymy. At the commencement of the present study previous works credited a total of 16 species in four genera to Tasmania distributed as follows: Galaxias, 12 species, Paragalaxias, 1 species, Saxilaga, 2 species and Brachygalaxias, 2 subspecies. In the present study G. scopus Scott is shown to be a synonym of G. truttaceus Valenciennes, G. affinis Regan and G. coxii Macleay are shown to be synonyms of G. brevipinnis Gunther which is recorded for the first time from the Australian mainland. The two species currently referred to the genus Saxilaga, S. cleaveri Scott and S. anguilliformis Scott, together with G. upcheri Scott are found to represent one species of Galaxias. The type locality of G. auratus Johnston is shown to be Lake Sorell and the type locality of G. upcheri is more accurately defined than in previous works. The two subspecies of Brachygalaxias, B. pusillus tasmaniensis Scott and B. pusillus flindersiensis Scott, are treated as one species of Galaxias. The Tasmanian galaxiid fauna is compared and contrasted with the galaxiid faunas of mainland Australia and New Zealand and the distribution patterns and zoogeographic considerations are discussed.

We took a hierarchical approach to understanding Atlantic salmon (Salmo salar) life history patterns by first comparing salmonids to other teleosts, next comparing Atlantic salmon to other salmonids, and finally, mapping correlations among individual life history traits within Atlantic salmon. The combination of anadromy, large eggs, nest construction and egg burial by females, and large size at maturity differentiates salmonids from most other teleosts. Within the family Salmonidae, there is considerable variation in all traits but Atlantic salmon are generally in the middle of the range. Within Atlantic salmon, we were able to map correlations among individual life history traits, but we found that we still lacked an understanding comprehensive and quantitative enough to allow us to predict how the entire life history should respond to environmental changes. Thus, we proposed several general courses of action: (i) use models to synthesize complex patterns and relationships, (ii) collect long time series of data in individual systems, and (iii) design experiments to assess phenotypic plasticity and how environmental influences differ from genetic effects and constraints.

В истории Армении раннесредневекового периода исключительно важную роль играли аристократические династии, составляющие сословие нахараров. Фактически вплоть до эпохи арабских нашествий в руках нахарарских кланов были сосредоточены основные земельные, военные и экономические ресурсы страны. В этой связи различные аспекты истории, включая вопросы генеалогии и просопографии соответствующих родов, давно находятся в поле зрения арменоведов. Одной из давно разрабатываемых в науке проблем является анализ достоверности сообщений средневековых авторов об иноэтническом (персидском (парфянском), иудейском, ченском (?китайском), римском) происхождении ряда нахарарств. Для истории Алании и армяно-аланских связей значительный интерес представляет нахарарство Аравелеанов, связанное, согласно Мовсесу Хоренаци, с родом царевны Сатиник. В статье обобщены высказывавшиеся в науке мнения о достоверности сообщений о выезде предков Аравелеанов из Алании, этимологии фамильного имени, локализации родовых владений, а также места, занимаемого кланом в рамках нахарарского сословия. Впервые на основе всего корпуса нарративных и эпиграфических источников собраны сведения об известных на сегодняшний день представителях рода. Выявлена информация о семи носителях фамилии V – VII вв. На основе имеющихся данных можно заключить, что Аравелеаны сыграли заметную роль в ключевых событиях армянской истории рассматриваемого периода – войнах Варданидов и борьбе с арабскими завоевателями. Отдельный интерес представляет получение представителями рода высоких византийских титулов. Составлена просопографическая анкета Аравелеанов. Noble dynasties, which formed a stratum of nakharars, have played exceptionally significant role in the history of the Early Tertiary period of Armenia. Actually, until the epoch of the Arab conquests, the majority of land, military and economic resources of the country was concentrated in nakharars’ hands. In this connection, different historical aspects, including questions of genealogy and prosopography of respected dynasties are now in the sight of Armenologists. One of the scientific problems which has been studied in depth for a long time is the analysis of source credibility of medieval authors’ statements about nonethnic origin of range of nakharars – Persian (Parthian), Hebrew, Chen (?Chinese), Roman. For the history of Alania and Armenian-Alanian relations, the Aravelian nakharar, which according to Movses Horenazi is connected to the dynasty of Queen Satinik, is of substantial interest. The article summarizes expressed scientific opinions on credibility of statements about departure of Aravelians’ predecessors from the territory of Alania, etymology of the family name, localisation of ancestral lands as well as position of the clan in frames of nakharar stratum. For the first time, on the basis of the whole corpus of narrative and epigraphic sources, the data on currently known members of Aravelians is collected. Information about seven family name bearers of V – VII centuries is being brought into light. On the basis of the available data, it can be concluded that Aravelians have played a significant role in the key milestones of the Armenian history during the period under review – Vardanid wars and fight against Arab invaders. Acquisition of high Byzantine titles by the members of the family is of specific interest. Phosopographical form of the Aravelians was made by the author.

The digger wasp genus Kohliella Brauns, 1910, a member of the tribe Larrini, subfamily Crabroninae of the family Crabronidae, is a rarely occurring genus comprising only three known species worldwide (Pulawski 1991; 2020). The genus has been recorded from the Ethiopian (South Africa and Zimbabwe; two species) and Oriental (Sri Lanka; one species) regions. Brauns (1910) erected the genus based on the type species Kohliella alaris from South Africa. The genus is characterized by a V-shaped swelling on the frons, an oblong tubercle on the mandible and a petiolate third submarginal cell of the forewing (Bohart & Menke 1976; Pulawski 1991). The nesting habits are known only for Kohliella alaris. Gess and Gess (1980) studied the life history of this species. It preys on nymphal tree cricket Oecanthus filiger Walker, and nests in the ground in flat, sandy areas with sparse vegetation; nests are constructed prior to hunting. In this paper, Kohliella anula Pulawski, 1991, previously known from Sri Lanka only, is recorded for the first time from India.

AbstractThe life of Ayuba Sulayman Diallo (also known as Job ben Solomon) receives a fresh examination in this article, based primarily on his own writings. The son of an Imam from Bundu in Senegambia, Diallo was enslaved in 1731 and transported to America. He survived to gain his freedom, make his mark in London society, and return to Africa in 1734. This article offers an analysis of documents from the British Library, including items that have not been previously analysed and are here translated into English for the first time. In addition, they bring together what is known of his archive, including the letters he wrote before, during, and after his time in London, the Qur'ans he scribed there, and the scraps and snippets created as he discussed the Arabic language with friends.A close analysis of Diallo's writings reveals new information about his life history; his relationships with the elites in both Bundu and London; his scholarly abilities; and the history of Bundu itself. Diallo used the technology of writing to direct the course of his own life and career, converting a disastrous course of events into favourable opportunities for himself.

1. Neottiophilum praeustum (Meigen 1826) is an Acalypterate fly, the larva of which inhabits the nests of various birds, e.g. Greenfinches, Chaffinches, Linnets, Thrushes and Blackbirds.2. The structure of the early stages of this fly namely eggs, larva and pupa is here described for the first time.3. Hendel's view that Neottiophilum should be separated into a new family is confirmed.4. The larvae of Neottiophilum live as intermittent blood-sucking parasites upon the birds. Their feeding habits are similar to those of Phormia and Passeromyia.5. The structure of the pharynx in Cyclorhaphous Dipterous larvae gives important indications as to the mode of feeding. Those larvae which are provided with longitudinal ridges are saprophagous or living upon decomposed vegetable or animal substances, while those which are devoid of ridges are biontophagous or feeding upon living substances (parasites in plants and in animals, predaceous or living in the uterus of the mother).6. This generalisation, when applied to the study of myiasis in plants, animals and man, enables us to separate them into two categories: (1) primary or parasitic myiasis and (2) secondary or pseudoparasitic myiasis, these being either accidental (intestinal) or following upon bacterial infection.

At the beginning of the nineteenth century journeys to the Crimea had only been coming into fashion among the Russian nobility, and by the end of the century this tendency had spread beyond aristocratic avocations. The Crimea became popular among merchants and manufacturers, philistines and clerks. The article studies the circumstances of the Crimean vacations of the family of Dmitriy Burilin at the turn of the nineteenth — the twentieth century´s. Dmitriy Burilin (1852-1924) was a manufacturer, Maecenas, collector, and founder of a museum in Ivanovo-Voznyesensk. He was a distinguished public figure of the Russian province at the turn of the centuries. His family travelled a lot through the country and abroad. The Crimea was a favorite place of the Burilins´ vacations. While at the very beginning of the 1900s the Crimean peninsula had served as a starting point of their voyages through Southern Europe (by the steamships of the Russian company of trade and steamship in Sevastopol), in the 1910s the Burilins opened the Southern part of the Crimea and stayed there for a long time. The family were coming there for health, to know about ancient and medieval history. Those journeys also served as family education. The Burilins visited Yalta several times, stayed at fashionable hotels of that time — «Metropol» and «Russia». During their vacations in Alupka and Gurzuf they had been treated by the leading doctors of that time. In Feodosiya Dmitriy Burilin had seen the works of Ivan Aivazovsky for the first time. Later he became the worshipper of Aivazovsky´s works and added some of them to his collection. The source base of the research consists of the Burilins´ correspondence, containing in the collection of the Ivanovo state historical museum.

AbstractNearctic mites of the family Anisitsiellidae are reviewed. A key and revised diagnoses are presented for the four genera, keys to species are provided for the first time, and distributional data are reviewed for each of the 13 known species. Three original species groups of Bandakia are proposed based on knowledge of nearctic species, but with the four exotic species tentatively placed. Adults of four new nearctic species, Bandakia borealis n. sp., Bandakia oregonensis n. sp., Bandakia fragilis n. sp., and Bandakiopsis fonticola n. gen., n. sp., are described. Reared larvae of Bandakia vietsi Cook and Bandakia borealis n. sp., the first known anisitsiellid larvae, also are described providing new insight on life history and phylogeny in the Anisitsiellidae.
