Aim. In this work, we aimed to study the distribution and habitat of rare Caucasian tenebrionid beetle Hedyphanes nycterinoides, as well as to identify reasons for the population re‐ duction and to develop a basis for its protection.Methods. Materials from the largest collection of the Zoological Institute RAS (St Petersburg) along with the authors’ fieldwork data were used for mapping the past and current distribution of the species, as well as for studying its habitat and possible trophic relations.Results. The taxonomic history of H. nycterinoides is complicated due to the loss of the type material. This taxon is currently interpreted as a separate species. H. nycterinoides is distributed across Piedmont Dagestan and Intermountain Dagestan (Russia); however, all known specimens were collected only in the 19th‐20th centuries (the last record is dated 1984). The population of H. nycterinoides from Intermountain Dagestan is likely to have died out due to the filling of the Irganay reservoir in 2008. Only one present‐day population from the arid Rubas valley in Southern Dagestan is known. The species inhabits saline soils (solonetz, solonchak) and feeds on saltworts. It is active in April–May in the evening or in the daytime provided it is cloudy.Conclusions. We recommend that H. nycterinoides be included in the list of threatened species of Dagestan as an indicator of the state of halophytic plant communities from the hilly landscapes of the Eastern Caucasus. The main factors of the contemporary population reduction include overgrazing and filling of reservoirs.

Based on a single well-preserved specimen from Eocene Baltic amber, a new tenebrionid beetle Neomida groehni Nabozhenko et Bukejs sp. nov. (Diaperinae: Diaperini) is described and illustrated using phase-contrast X-ray microtomography. This oldest representative of the genus differs from all known extant and extinct congeners by the dorsally very weakly convex pronotum with undulate lateral margins (while other Neomida have a pronotum that is strongly convex along its transverse axis, with evenly rounded lateral margins); distinct, right posterior angles of pronotum; and elevated sutural area of the elytra.

The tribe Heleini is redefined to exclude the genera Lepispilus Westwood, 1841, and Leaus Matthews & Lawrence, 1992, which become incertae sedis within the subfamily Tenebrioninae . Four generic names are synonymised as follows: Barytipha Pascoe, 1869, and Pezohelaeus Gebien, 1920, with Pterohelaeus Brême, 1842; Euhelaeus Gebien, 1920, with Emcephalus Kirby, 1828; and Saragella Carter, 1937, with Dysarchus Pascoe, 1866. The genus Saragus Erichson, 1842, is resurrected as separate from Celibe Boisduval, 1835, with which it had been confused, and two new genera (Boreosaragus and Cillibus) are proposed for other species formerly in Celibe, bringing the total to 14 genera in the tribe, which is distributed in Australia, New Zealand, New Guinea and Seram. A tentative phylogeny is proposed for the genera, the constituent species are either mentioned or reference is made to a former checklist, and the Australian distribution of all but two genera is plotted. Hypotheses are put forward on evolutionary trends and the past history of the tribe. The 27 new combinations proposed are listed in Appendices I and II at the end of the paper.

Turkonalassus mavi M. Nabozhenko & B. Keskin, sp. n. and Odocnemis rufocruralis M. Nabozhenko & B. Keskin, sp. n., two distinctive darkling beetle species of the tribe Helopini, are described from the Southeastern Anatolia region of Turkey, based on both their external morphology and genital structures. Turkonalassus mavi sp. n. differs from all congeners by the bluish dorsal surface of the body, the pronotum widest before middle, and wide merged baculi of the median lobe of the aedeagus. Odocnemis rufocruralis sp. n. belongs to the praelonga species-group. Odocnemis rufocruralis sp. n. is similar to O. torosica Nabozhenko & Keskin, 2016, O. terminassianae (Nabozhenko, 2011) and O. kakunini Nabozhenko & Keskin, 2016 but differs from all three taxa by the reddish-brown body with red legs, male apical maxillary palpomere wider than in female, elevate and narrowly separate male protrochanters, and the structure of the very long and narrow apical piece of the aedeagus. New data on distribution, bionomics, and trophic relations of several species of Helopini from Turkey are given. Host lichens are determined for nine species. The majority of studied adult beetles feed on lichens from the families Physciaceae and Parmeliaceae. Some examined taxa feed on Cladoniaceae. Feeding on crustose lichens is registered for the first time for Coleoptera, specifically Odocnemis rufocruralis sp. n. was observed to feed on Pertusaria sp. (on Prunus) in Mardin Province.

It is generally accepted that history is an element of culture and the historian a member of society, thus, in Croce's aphorism, that the only true history is contemporary history. It follows from this that when there occur great changes in the contemporary scene, there must also be great changes in historiography, that the vision not merely of the present but also of the past must change.

It is perhaps one of the most important characteristics of the past decade in astronomy that the evolution of some major classes of astronomical objects has become accessible to detailed research. The theory of the evolution of individual stars has developed into a substantial body of quantitative investigations. The evolution of galaxies, particularly of our own, has clearly become a subject for serious research. Even the history of the solar system, this close-by intriguing puzzle, may soon make the transition from being a subject of speculation to being a subject of detailed study in view of the fast flow of new data obtained with new techniques, including space-craft.

Purpose The current “specific language impairment” and “developmental language disorder” discussion might lead to important changes in how we refer to children with language disorders of unknown origin. The field has seen other changes in terminology. This article reviews many of these changes. Method A literature review of previous clinical labels was conducted, and possible reasons for the changes in labels were identified. Results References to children with significant yet unexplained deficits in language ability have been part of the scientific literature since, at least, the early 1800s. Terms have changed from those with a neurological emphasis to those that do not imply a cause for the language disorder. Diagnostic criteria have become more explicit but have become, at certain points, too narrow to represent the wider range of children with language disorders of unknown origin. Conclusions The field was not well served by the many changes in terminology that have transpired in the past. A new label at this point must be accompanied by strong efforts to recruit its adoption by clinical speech-language pathologists and the general public.

Abstract. Background: Medical students are at high risk of suicidal ideation. Aim: We aimed to obtain information on suicidal ideation among medical students in Dammam located in the Eastern Province of Saudi Arabia. Method: This cross-sectional study was conducted at the College of Medicine affiliated with Imam Abdulrahman Bin Faisal University in the Eastern Province of Saudi Arabia. Suicidal ideation in the past 12 months was assessed based on responses to four questions in the depression subscale of the General Health Questionnaire 28 (GHQ-28). In addition, data were collected to examine the association of suicidal ideation with various factors. Results: We found that 1 in 3 medical students in the study had suicidal ideation in the past 12 months, while around 40% had lifetime suicidal ideation. Suicidal ideation was associated with feelings of parental neglect, history of physical abuse, and dissatisfaction with academic performance. Limitations: The cross-sectional nature of this study limits its ability to determine causality regarding suicidal ideation. Conclusion: These rates are considerably high when compared with rates from studies in other countries around the world. This study provides a reference in the field of suicidology for this region of Saudi Arabia.

The article is devoted to major events in the history of the post-Soviet economy, their influence on forming and development of modern Russia. The author considers stages of restructuring, market reforms, transformational crisis, and recovery growth (1999-2011), as well as a current period which started in2011 and is experiencing serious problems. The present situation is analyzed, four possible scenarios are put forward for Russia: “inertia”, “mobilization”, “decisive leap”, “gradual democratic development”. More than 30 experts were questioned in the process of working out the scenarios.
