The caliscelid genus Symplana Kirby, 1891 is revised, with the type species, S. viridinervis Kirby, 1891, is redescribed based on the lectotype. Three new species are described: Symplana maurici sp. n. and S. vieta sp. n. – from northwestern and central Vietnam and S. sultana sp. n. – from eastern Sumatra. Symplana elongata Meng, Qin et Wang, 2020 is placed in synonymy under S. brevistrata Chou, Yuan et Wang, 1994. Key to species of the genus is given. Peculiarities of connective structure and its connection with an aedeagus as well as fusion of endogonocoxal lobes in ovipositor are discussed and illustrated for different Augilini taxa and compared with other Caliscelidae.

A new oribatid mite species of the genus Oribatella (Oribatida, Oribatellidae)—Oribatella altaica Ermilov sp. n. – is described from soil-litter in Altai mountains, Russia; it is showing an interesting sexual dimorphism in the structure of the posterior part of notogaster (large unpaired concavity bearing a pair of porose areas A3 present in males versus concavity absent, A3 located openly on notogastral surface in females). In addition, data on the known sexually dimorphic Oribatella species are presented.

In the nature, larvae living in watercourses are exposed to a complex system of environmental influences. It is known that different watercourse types (creeks, brooks, streams, little rivers and medial rivers) provide different conditions for larval development (water depth, flow rate, temperature, oxygen content, substrate type, nutrient supply, etc.). These conditions can vary significantly between watercourse types, but be very similar within types. In this work, we examined the body sizes and wing morphometric characteristics of males of Calopteryx splendens reared from different watercourse types (brook, stream, creek, little river, medial river). Although there were no significant differences in body size among watercourse types, we found significant differences in the wing features. We found the most differences between the individuals reared from streams and creeks and between the individuals reared from stream and medial river. Our results show that the individuals reared from different watercourse types were clearly separated on the two wings. The results also suggest that there are significant differences in the number and pattern of allometric features on the wings of individuals reared from different watercourse types.

We present an annotated check-list of Pteromalidae (Hymenoptera: Chalcidoidea) from Sakartvelo (the Republic of Georgia), updating the available information of these parasitoids. We identified 22 species belonging to 17 genera from 9 subfamilies – Asaphinae, Cerocephalinae, Cleonyminae, Miscogastrinae, Pteromalinae and Spalangiinae. One species, Psilocera kartveli László et Kelemen sp. n., is described as a new for science, and the remaining 21 species are new records for the fauna of Georgia, from which 10 species are new for the Caucasus. All the 17 genera are recorded for the first time for the Georgian fauna. For each species, their biology and distribution are presented.

Taxonomic subdivision of Ichthyosaura alpestris (then Triturus) was recognized by Dely in 1964 in his dissertation. While other subspecies were described in other publications, he did not publish the name Triturus alpestris bakonyiensis in valid form according to ICZN. Therefore the nomenclatural validation of this subspecies is given here.

Ostracods are one of the most suitable organisms because of their ecological and morphological preferences for habitat types to study the diversity between streams and lakes. Here, 24 streams and 16 lakes were sampled in 2019 to evaluate the species compositions between streams and lakes. Environmental heterogeneity in the sense of the physico-chemical variables was found among the habitats. 24 of the 29 species with 923 individuals were found in the lakes when 13 species with 898 individuals were found in the streams. Eight species were common in both habitat types. Species contributing about 70.81% to the significant differences in the species composition between the habitats showed cosmopolitan characteristics. Species variation among the replicates of lakes were higher than streams. Results indicated that the species composition was probably associated to dissolved oxygen in lakes, while electrical conductivity in streams. Relationship amid elevational range and ostracod species richness was negative in lakes when there was no clear relationship in the streams. Overall, results suggested that determination of influential regional factors in different aquatic bodies can provide important contributions to the estimation of which habitat types can be chosen by species, and the using of species as bioindicators.

The taxonomically important characters and subgeneric subdivision of Dichagyris are presented with several historical and nomenclatural considerations. Subdivision of D. vallesiaca is revised based on the type material of the known subspecies. The D. psammochroa group is revised, with description of a new species, D. kurbatskyi from Kazakhstan, and one new subspecies, D. psammochroa kopetdaghimena from the Kopet-Dagh massif. The D. taftana group is revised, with the description of a new species (D. guentereberti from Afghanistan) and two new subspecies (D. taftana elborsasta and D. taftana safavida, from different areas of Iran). The eastern sister species of D. humilis, D. hypotacta from Afghanistan and Pakistan, is described. Major phylogenetic clades of Dichagyris s. str. are associated to western Palaearctic and/or Central Asiatic mountainous regions. Core areas of allopatric speciation of Dichagyris s. str. are discussed with taxonomic considerations and outlook on the subgenera Yigoga and Albocosta, as well.

Among ten adult specimens of the Madeiran endemic land snail Leptaxis simia kept in the laboratory, a single clutch of 110 eggs was reared, and the mortality, growth and reproductive capacity of hatchlings over a 1240- day period were monitored. Of 70 hatchlings, 34 survived to complete shell growth at around 640 days. Growth was rapid, and mortality high in the early stages; growth slowed and mortality was very low as full size was approached. Snails kept singly failed to lay any eggs. Among those with potential mates, only three clutches were produced, one of which yielded no hatchlings. Clutches were produced at least five months after shell growth was complete. Mortality increased sharply after the onset of sexual maturity, and the oldest snail survived for three and a half years. The apparently very strictly semelparous mode of reproduction, delayed sexual maturity and relatively long period of juvenile growth are discussed in relation to other species, and to the practical problems of rearing potentially endangered species in captivity.

Growth was rapid, and mortality high in the early stages; growth slowed and mortality was very low as full size was approached. Snails kept singly failed to lay any eggs. Among those with potential mates, only three clutches were produced, one of which yielded no hatchlings. Clutches were produced at least five months after shell growth was complete. Mortality increased sharply after the onset of sexual maturity, and the oldest snail survived for three and a half years. The apparently very strictly semelparous mode of reproduction, delayed sexual maturity and relatively long period of juvenile growth are discussed in relation to other species, and to the practical problems of rearing potentially endangered species in captivity.","PeriodicalId":55558,"journal":{"name":"Acta Zoologica Academiae Scientiarum Hungaricae","volume":" ","pages":""},"PeriodicalIF":0.8,"publicationDate":"2021-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42518960","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
