The paper reviews all available information on the species content, distribution and ecology of brackishwater hydrobiid snails belonging to the genusCaspiohydrobiaStarobogatov, 1970. The annotated list of nominal species with remarks on their taxonomy, nomenclature and distribution is provided as well as photographic images of some type specimens and/or topotypes. In total, the genus includes 31 nominal species distributed almost exclusively within the former Paratethys basin. The lectotype for the speciesC. cylindricaLogvinenko et Starobogatov, 1969 is designated. A short overview of the known habitat preferences of variousCaspiohydrobiaspecies is provided. We considerCaspiohydrobiaa genus of Ponto-Caspian origin, whose range extends southwards to Iraq, Iran and Tajikistan and northwards to West Siberia. The actual species content of the genus as well as its generic independence require a further integrative revision, since most of the nominal species ofCaspiohydrobiaare still known from dried shells only and may actually be synonyms of a few (or even a single) species.

Clathrocaspia isseli (Logvinenko & Starobogatov, 1969) — Anistratenko et al. 2021: 174, fig. 12i–l, q. Type material. Holotype (ZIN 1 /532-2021) and 32 paratypes (ZIN 2 /532-2021) derive from the same lot, labeled “50/1957” (Tab. 1, locality 16), collected by B.M. Logvinenko off Cheleken Peninsula on 4 August 1957. Further 128 paratypes (ZIN 3 /532-2021–8/532-2021, 11/532-2021 and 12/532-2021) are stored in eight separate tubes, labels only marked with the number of station and year, collected in various parts of the Middle (Tab. 1, locality 2) and South (localities 14, 15, 16, 17, 21, 42) Caspian Sea between 26 June 1956 and 2 August 1957 (Fig. 1). Type locality. Originally given as “Southern Caspian Sea between 40–75 m water depth” without further details (Logvinenko & Starobogatov 1969). The holotype was collected in the Caspian Sea off the Cheleken Peninsula, Turkmenistan (Table 1, locality 16) from 71 m depth. Remarks. Recently rediscovered material determined by Starobogatov as the paratypes of C. isseli contain a variety of morphologies. Some match the typical C. isseli as described by Logvinenko & Starobogatov (1969) and the morphology of the holotype (Fig. 2a, b). However, some paratypes (Fig. 2i, j, o–r) resemble C. pallasii (Clessin & W. Dybowski in W. Dybowski, 1887) closely and study of these and additional material confirms that some of the paratypes were classified under that species correctly (Anistratenko et al. 2021). Despite their overall similarity in shell shape, C. pallasii can be distinguished from C. isseli by the consistently lower whorl base, the less convex whorl profile, the slightly detached aperture and the larger and more bulbous protoconch. Clathrocaspia isseli differs from C. gmelinii (Clessin & W. Dybowski in W. Dybowski, 1887) in its more slender shape (see Anistratenko et al. 2021 for further details). Distribution. Endemic to the Caspian Sea, only known from 8 localities (see above) in the Middle and South Basins from water depths of 40 and 107 m. Also found in the Holocene deposits of the Kura delta (Anistratenko et al. 2021)., Published as part of Anistratenko, Vitaliy V., Sitnikova, Tatiana Ya. & Anistratenko, Olga Yu., 2021, Holotypes for three Caspian gastropods of the family Hydrobiidae tracked down description and taxonomic interpretations, pp. 408-416 in Zootaxa 5027 (3) on page 412, DOI: 10.11646/zootaxa.5027.3.6, http://zenodo.org/record/5449761, {"references":["Logvinenko, B.

В статье раскрываются особенности появлений детских страхов. Авторами описывается арт-терапия как один из эффективных методов работы с проблемами страха у детей.

The phenomena of computer games and the plethora of game cultures have already been drawing attention of researchers for many years, whereas the people behind computer games – the so called gameworkers – undeservingly remained in the shadows until quite recently. The lack of information about this workforce and its professional identity makes this research object especially interesting. The analysis relies on a pilot study about the issue of the professional identity of gameworkers, which aimed to dig deeper with the means of qualitative research. During that project nine German gameworkers were interviewed and an attempt to give an in-depth description of their professional identity was made. The study shows that the respondents have a very strong coherence with their profession and perceive themselves as a part of their profession and the team/studio they work with/at. The most salient reason for this is the deep interest the respondents have in computer games (for both making and playing games).
