History Of

Diptera is one of the most speciose groups within Insecta, but there are deep gaps in knowledge of the South American faunas. Conopidae, also known as thick-headed flies, inhabit many habitats around the world, and are particularly diverse in the Neotropical region. Despite this, southern South American species of this group are poorly known and many genera are under-represented in museum collections. Only four Neotropical species of Myopa are known, three from Mexico and one from Chile. In this study we describe two new species: Myopa nebulosa sp. nov. distributed from northern Chile to the Maule region of central Chile, and Myopa bozinovici sp. nov. from Mediterranean ecosystems of central Chile. We also re-describe the conspicuous species Myopa metallica Camras and provide an updated key to all Neotropical species of this genus. The natural history of these species is unknown. Myopa species are not abundant and their habitats may be threatened by land change use.

A New Species

Centris (Paracentris) Cameron is one of the more diverse subgenera within the bee genus Centris (Moure et al. 2007), being broadly distributed in the Neotropical Region, and showing an amphitropical distribution pattern (Michener 1979). The sixteen South American species of Centris (Paracentris) (Zanella 2002; Moure et al. 2007) occur in different biomes of the continent; such as low altitudes and valleys of Central Chile and Argentina (Roig-Alsina 2000; Vivallo et al. 2003), high altitudes of the Andes (they are specially diverse in this region) and with a few species in the low mountain chains and plains of Eastern Brazil (Zanella 2002). The subgenus was recently revised by Zanella (2002) and a new species from Central Peru is described here, which augments that revision.

The World

An overview of the major zoogeographical gaps in our knowledge of the world beach flies (subfamilies Apetaeninae, Horaismopterinae, Pelomyiinae, and Tethininae) is provided. The identified areas treated in this work are as follows: the subarctic Beringia, the South American circum-Antarctic islands, the Neotropical Region south of the equator, most of the West African seacoasts, the huge area ranging from India, across the Bay of Bengal, to Sumatra and Java, and most of Australia. Apart from the inhospitable northernmost and southernmost areas of the planet, which feature a real very low biodiversity, the remaining vast areas dealt with in this work woefully suffer a dramatic paucity of field collections, as well as of previously collected materials preserved in scientific institutions. This might seem a truism that, however, must be emphasized in order to unequivocally identify the geographic areas that need to be further investigated

Pollinator Rewards

Floral oils as reward to pollinators occur in eleven plant families and appeared at least 28 times in the evolutionary history of flowering plants. They are produced in epithelial or tricomatic glands and collected by oil bee visitors. The present paper focuses on floral-oil-producing species of Plantaginaceae, a Neotropical group namely Angelonia clade. This group comprises around 40 described species in the genera Angelonia, Basistemon, Monttea, Monopera and the oil-less Melosperma. We present a revision of all species of the Angelonia clade, their geographical distribution, resources offered to pollinators and records of flower visitors, especially oil-collecting bees. These plants rely only on oil-collecting species in the tribe Centridini and Tapinotaspidini for a successful pollination, being the interaction between both partners an especial case of bee/flower adaptation in Neotropical region. Some bee species depend only on the oil of Plantaginaceae flowers to survive, while others can collect on several floral oil sources. The pollinating bees explore the oil glands located in sacs using specialized hairs in the forelegs. With this study, we hope to inspire further research relating to this fascinating group of plants, in which most species are rare and occur in highly endangered habitats in South American open vegetation biomes.

A New Species

Rheotanytarsus is a speciose genus, currently composed by more than 100 nominal species distributed worldwide, 19 are known from the Neotropical region, four from South America and only one is registered for Peru. In the present study, a new species is described and illustrated based on males collected in the Peruvian Andes. In addition, the key to the South American species is updated and a distribution map of them is provided. Rheotanytarsus amaru sp. n. is easily distinguished from the congeneric species by the dark general coloration and the hypopygial morphology.

A New Species

The spider family Nesticidae includes 233 species in 13 genera and is distributed almost worldwide (World Spider Catalog, 2016). However, the family is still poorly known in the Neotropical Region. The genus Nesticus Thorell, 1869 comprises 132 species and seven subspecies and was described based on N. cellulanus (Clerck, 1757), from Europe (World Spider Catalog, 2016). Meridional South American species of Nesticus were revised by Ott & Lise (2002). More recently, Faleiro & Santos (2011) described a new species from the state of Minas Gerais, Brazil and Torres et al. (2016) a new species from the province of Salta, Argentina. Nowadays, Nesticus is represented by six species in Brazil: Nesticus brasiliensis Brignoli, 1979; Nesticus brignolii Ott & Lise, 2002; Nesticus calilegua Ott & Lise, 2002; Nesticus ivone Faleiro & Santos, 2011; Nesticus potreiro Ott & Lise, 2002 and Nesticus taim Ott & Lise, 2002 (World Spider Catalog 2016).

Abstract Six species of birds of the family Sternidae are often found on the southern coast of South America. Sterna trudeaui, S. hirundinacea, Thalasseus maximus, T. acuflavidus and Sternula superciliaris are South American residents and Sterna hirundo, a Nearctic migrant. At least 500 species of nasal mites have been described around the world, and Rhinonyssidae is the most diverse family. These mites are bloodsucking endoparasites that inhabit the respiratory system of birds. This study aimed to report on occurrences of nasal mites in Sternidae on the southern coast of Brazil. Of the 106 birds analyzed, 8.5% (9 birds) were parasitized by nasal mites. This report provides the first record in the Neotropical region for two mite species, Sternostoma boydi and Larinyssus orbicularis parasitizing Thalasseus acuflavidus and Sternula superciliaris. No nasal mites were found in Sterna trudeaui or Thalasseus maximus. One host individual (T. acuflavidus) was parasitized by two species of nasal mites, S. boydi and L. orbicularis.

The genus Centris Fabricius, 1804 is one of the more diverse lineages of solitary bees in the Neotropical Region with more than250 described species. Here Centris ceratops new species is described from a tropical dry forest in northern Colombia (Colosó,Department of Sucre), thus increasing the number of known species to four in which the females possess a horn-like projectionon the clypeus. This group of bees belongs to a small monophyletic group within C. (Heterocentris). Along with the description of this new species, diagnosis, pictures and a key to identify the species of females with modified clypeus are also provided.

Due to the fact that in 2020 the whole world celebrates the 175th anniversary of the birth of I.I. Mechnikov, in order to preserve and promote the spiritual culture of Slobozhanshchina and to create a chronicle of unknown pages of the history of our region that is the small motherland of the great scientist, a number of events have been held. At the initiative of Dvorichna Children and Youth Creativity Center in 2015 the museum “Our great countryman I.I. Mechnikov — the Citizen of the World “ was established and a strategic plan for its development was developed. In the process of researches a fund of museum objects and museum collections of historical and cultural content was created in accordance with the tasks set for the museum. The museum has almost 400 exhibits of the main fund. The museum offers tours for visitors of all ages. In recent years we have intensified cooperation with many higher education establishments. We are supported by scientists-followers of I.I. Mechnikov from Israel, the USA, France, Great Britain, Latvia by holding international Internet conferences. It has become a tradition to hold annual Mechnikov readings.

Museums convincingly achieves the aim of giving a general summary of the key themes of the museum’s history. The author does not fail in missing a point: he offers a comprehensive history of museums from the ancient world to contemporary times, focusing on well-known historical examples of museum collections taken from different parts of the world and on contemporary subjects of debate in the museum world, producing a valuable synthesis of this wide topic. I recommend this book to museum studies students interested in the history of museums, but also to scholars who would like to have a complete and valuable summary of the subject.
