A fairyfly (Hymenoptera, Mymaridae) Cleruchus breviclava Triapitsyn & Coray, sp. nov. is described and illustrated. The new species is an egg parasitoid of the invasive Cis chinensis Lawrence (Coleoptera, Ciidae) in Antrodia xantha fungus (Polyporales, Fomitopsidaceae) in Basel, Switzerland; it is also known from low mountains in Germany and Switzerland. Supporting data on the “barcoding” region of the mitochondrial cytochrome c oxidase subunit I gene, as well as separate regions of nuclear ribosomal RNA, the D2 region of 28S and the internal transcribed spacer 2, provide strong evidence of conspecificity of the morphologically variable macropterous and strongly brachypterous individuals of C. breviclava. Macropterous females of the new species are most similar to those of C. detritus Bakkendorf, also known from Switzerland. New records are provided for some other species of Cleruchus Enock in Europe. A key to both sexes of the described European species of the genus is given.

Samples of the tree fungus Antrodia xantha were collected on Pinus strobus in the therapy garden of the UPK campus (University Psychiatric Clinics) in Basel in summer 2021. The samples contained an alien Ciidae species new to Switzerland: Cis chinensis Lawrence, 1991, a species otherwise mainly known as a storage pest of commercially dried fungi. The adults and larvae of the Basel population are described and illustrated. When comparing the size of the adults of the two sample series collected two weeks apart, statistically significant differences were found. It appears that the above-average temperatures in June 2021 favoured the size of the second group. A number of (4–)5 larval stages are postulated for larval development. As an endoparasitoid of the eggs of C. chinensis, an unknown Mymaridae of the genus Cleruchus was found. Noteworthy was an unusually heavy infestation of Ciidae by phoretic mites (Histiostomatidae). During follow-up surveys in early 2022, additional individuals of C. chinensis were also found on the fruitbodies of other fungi growing in the immediate vicinity of the site where the population of the species was initially observed on A. xantha. A list of all Ciidae detected on the UPK campus is provided, and the spectrum of host-fungi of C. chinensis is discussed.

A focused search in very high (2500–3200 m asl) Alpine mountain tops in France resulted in the discovery of the very rare Alpine-endemic syrphid Platycheirus altomontis Merlin & Nielsen in Nielsen, 2004, including its hitherto unknown female. A description of the female is given and further complemented with behavioural observations of this species with special reference to hilltopping. Additional records and behavioural observations are provided for rare and new species for the French fauna from the montane and Alpine habitat with focus on species of high altitude (>2750 m) and hilltopping behaviour. The species Rohdendorfia alpina Sack 1938 is new to France and was observed in large numbers at scree slopes above 2750 m and males were found sitting at hilltops up to 3200 m. Hilltopping behaviour of Syrphidae was observed over the whole altitudinal range visited, and multiple species engaged in this behaviour even at above 3000 m. Hilltopping appears to be more common in some genera (e.g. Parasyrphus and Pipizella) than in others and may be linked to specific phenotypes in some species. The latter was observed for the species Cheilosia melanura (Becker, 1894) of which at high hilltops much smaller males were found than at lower altitudes.

We use molecular phylogenomic as well as morphological data to provide a taxonomic update on New Guinea endemic Philaccolilus diving beetles. In these lotic beetles, we find cryptic diversity that highlights the need for geographically denser sampling combined with the use of an intergrative taxonomic approach to unravel the true diversity and biogeography of these beetles. We describe three new species: P. intaniasp. nov. from the northern Bird’s Head Peninsula, P. kiranasp. nov. from the southern Bird’s Head as well as P. febrinasp. nov. which is more widespread on the Bird’s Head. Philaccolilus ameliae weylandensis is elevated to species rank, as Philaccolilus weylandensisstat. nov.

A new Periscelididae species, Periscelis (Myodris) haenniisp. nov., is described from Losone near Locarno, Canton Ticino (Southern Switzerland). It has been found during a biodiversity survey using attractant traps in a Querco-Castagnetum forest. This new species is closely related and very similar to P. (M.) annulata (Fallén, 1813) occurring syntopically in the same traps. Interestingly, also P. (M.) piricercus Carles-Tolrá & Verdugo Páez, 2009 co-occurred with these species; consequently, all European species of the subgenus Myodris Lioy, 1864 were found in this locality. A new illustrated key to males of these species is presented. The DNA sequences of the barcoding region of COI for all these species are given.

Meconema meridionale Costa (Orthoptera, Tettigoniidae) infected with Zoophthora giardii Bałazy (Entomophthorales, Entomophthoraceae) were collected at five localities in the northern half of Switzerland. At one of these sites, the fungus caused epizootics in two subsequent years. Symptoms and morphological data coincide with those given by Bałazy who found the fungus on Meconema thalassinum De Geer. Conidiobolus gustafssonii Bałazy (Entomophthorales, Ancylistaceae) was found on a single Ectobius vittiventris Costa (Blattodea, Ectobiidae). Symptoms and dimensions of the primary conidia correspond with the original description given by Bałazy who found the fungus on Ectobius lapponicus L. The two fungi are new for Switzerland and Meconema meridionale and E. vittiventris represent new hosts for these pathogens.

Two new species of the diving beetle genus Liodessus Guignot, 1939 are described from high mountain regions in Venezuela: Liodessus meridensissp. nov. from Laguna de Mucabají, Mérida and L. venezuelensissp. nov. from Laguna de Mucabají and below Pico Bolívar, Mérida. We delineate the species using morphological characters such as male genital structure and beetle size, shape and color. Mitochondrial cox1 sequence data provided an additional character source. Both new species occur at altitudes above 3,500 m and were collected in shallow water at the edge of high-altitude ponds.

The spatial scale of intraspecific genetic connectivity and population structure are important aspects of conservation genetics. However, for many species these properties are unknown. Here we used genomic data to assess the genetic structure of the small Apollo butterfly (Parnassius phoebus Fabricius, 1793; Lepidoptera: Papilionidae) across three nearby valleys in the Central Swiss Alps. One of the valleys is currently used for hydropower production with future plans to raise the existing dam wall further. We found no significant genetic structure, suggesting a currently high connectivity of this species in our studied region.

Lyonetia ledi Wocke, 1859 (Lyonetiidae), was hitherto considered as a boreal species with a circumpolar distribution pattern and relict populations in isolated peat bogs north-east of the Alps (Austria, Czech Republic, Germany). In Europe it is known as a leaf-miner on Rhododendron tomentosum Stokes ex Harmaja (Ericaceae) as the primary host-plant and also Myrica gale L. (Myricaceae). The first record of L. ledi from the Swiss Alps on Rhododendron ferrugineum L., the famous Alpenrose, indicates an ancient host-plant switch during postglacial periods when R. tomentosum and R. ferrugineum shared habitat in the prealps. Conspecificity with northern populations is supported by the adult morphology and supplementing DNA barcodes (mtDNA COI gene). L. ledi is the first obligatory leaf-mining species on R. ferrugineum. Details of the life-history and habitat are described and figured. The record finally substantiates the probability of an autochthonous population in Carinthia (Austria), from where the species was recently published as new to the Alps.
ledi Wocke狼蛛，1859年（狼蛛科），迄今为止被认为是一种具有环极分布模式的北方物种，在阿尔卑斯山东北部（奥地利、捷克共和国、德国）的孤立泥炭沼泽中有残余种群。在欧洲，它被认为是毛杜鹃（Ericacee）和杨梅（Myrica gale L.）的主要寄主植物。来自瑞士阿尔卑斯山的L.ledi在著名的Alpenrose Rhododendron ferrogineum L.上的第一次记录表明，在后冰川时期，毛白杨和ferroginium在前lps中共享栖息地，宿主植物发生了古老的转换。成虫形态和补充DNA条形码（mtDNA COI基因）支持与北方种群的共特异性。ledi是铁柏上第一个必须采叶的物种。详细的生活史和栖息地被描述和描绘。该记录最终证实了卡林西亚（奥地利）存在本地种群的可能性，该物种最近在阿尔卑斯山被公布为新物种。
