AbstractThe aim of this review is to summarize the literature knowledge about how abiotic environmental factors and biotic interactions affect the sequentially overlapping longitudinal distribution of Central European species of the net-spinning freshwater caddisfly larvae of the genus Hydropsyche (Trichoptera: Hydropsychidae). In this relation, several physical and chemical parameters of water are discussed, as well as different species-specific traits, behavioural aspects and the interaction of coexisting species. Longitudinal gradients of river networks, especially annual temperature range, flow velocity and the particle size of suspended food material play a crucial role in forming the downstream succession of characteristic species, while increased levels of organic pollution, nutrients, salinity and heavy metals facilitates the presence of more tolerant ones. Several species-specific traits, such as respiration range, net-building frequency, head capsule size or optimal net-building velocity correlate with the position of a given species in the sequence. Coexistence of species with similar ecological demands in the overlapping zones of distribution is facilitated by differences in feeding and net-building habits, microhabitat preferences and staggering life cycles, but complicated at the same time by means of inter- and intraspecific territorial behaviour, such as fighting for the ownership of larval retreats or the practice of stridulation.

Remarks on some European Aleocharinae, with description of a new Rhopaletes species from Croatia (Coleoptera: Staphylinidae) Based on an examination of type and non-type material, ten species-group names are synonymised: Atheta mediterranea G. Benick, 1941, Aloconota carpathica Jeannel et Jarrige, 1949 and Atheta carpatensis Tichomirova, 1973 with Aloconota mihoki (Bernhauer, 1913); Amischa jugorum Scheerpeltz, 1956 with Amischa analis (Gravenhorst, 1802); Amischa strupii Scheerpeltz, 1967 with Amischa bifoveolata (Mannerheim, 1830); Atheta tricholomatobia V. B. Semenov, 2002 with Atheta boehmei Linke, 1934; Atheta palatina G. Benick, 1974 and Atheta palatina G. Benick, 1975 with Atheta dilaticornis (Kraatz, 1856); Atheta degenerata G. Benick, 1974 and Atheta degenerata G. Benick, 1975 with Atheta testaceipes (Heer, 1839). A new name, Atheta velebitica nom. nov. is proposed for Atheta serotina Ádám, 2008, a junior primary homonym of Atheta serotina Blackwelder, 1944. A revised key for the Central European species of the Aloconota sulcifrons group is provided. Comments on the separation of the males of Amischa bifoveolata and A. analis are given. A key for the identification of Amischa species occurring in Hungary and its close surroundings is presented. Remarks are presented about the relationships of Alevonota Thomson, 1858 and Enalodroma Thomson, 1859. The taxonomic status of Oxypodera Bernhauer, 1915 and Mycetota Ádám, 1987 is discussed. The specific status of Pella hampei (Kraatz, 1862) is debated. Remarks are presented about the relationships of Alevonota Thomson, 1858, as well as Mycetota Ádám, 1987, Oxypodera Bernhauer, 1915 and Rhopaletes Cameron, 1939. The publication date of several Atheta species described by G. Benick is discussed. Aloconota mihoki, Amischa forcipata, A. filum and Atheta boehmei are reported from Hungary, Croatia and Romania, respectively, for the first time. A new species, Rhopaletes slavoniae sp. n. is described from Croatia.

SUMMARYThe Renicolidae are digenean parasites of piscivorous and molluscivorous birds. Although they exhibit few morphological autapomorphies and are highly variable, the numerous suggested re-classifications within the family have never been supported by any molecular analyses. We address the possible synonymization of species within theRenicola pinguiscomplex suggested previously by Odening. We provide and analyse sequences of two nuclear (ITS2, 28S rDNA) and two mitochondrial (CO1, ND1) DNA loci of central European species of the Renicolidae, namelyRenicola lari, Renicola pinguisandRenicola sternaesp. n., and we also provide first sequences ofRenicola sloanei. The combined molecular and comparative morphological analysis confirms the previously questioned validity of the threeRenicolaspp. of highly similar morphology, which display strict niche separation in terms of host specificity and selectivity. We identify two previously unreported clades within the genusRenicola; however, only one of them is supported by the analysis of adult worms. We also provide comparative measurements of the three examined closely related central European renicolids, and describe the newly proposed tern-specialized speciesRenicola sternaesp. n., which was previously repeatedly misidentified asRenicola paraquinta. Based on the extensive dataset collected in 1962–2015, we update the host spectrum of Renicolidae parasitizing central European birds (Renicola bretensis, R. lari, Renicola mediovitellata, R. pinguis, Renicola secundaandR. sternaesp. n.) and discuss their host-specific prevalence and intensity of infections.

The West European species of Boreonectes Angus, 2010 are reviewed. B. multilineatus (Falkenström, 1922) is shown to be widely distributed in the Pyrenees, where it is the only species known to occur. The chromosomes of all five west European species are found to have, in addition their different numbers of chromosomes, differences in the number and locations of secondary constrictions, and in some cases, the number of chromosomes with clear centromeric C-bands. The level of differences between the chromosomes of the species is in stark contrast with the very slight genetic (DNA) differences between them and this suggests that chromosome differentiation may have been a driver of speciation. Two of the species, B. griseostriatus (De Geer, 1774) and B. multilineatus, have distributions extending northwards as far as Arctic Scandinavia. It is pointed out that, while these northern areas now constitute the major portions of their ranges, they must be of fairly recent origins as most of the area would have been covered by ice sheets and therefore not habitable during the glacial maximum of the Last Glaciation. This contrasts with the situation in the area of the Central European mountains where fossil faunas, including Boreonectes, are known. B. griseostriatus, identifiable to species by its parameres, was present in the Woolly Rhinoceros site at Starunia in the Western Ukraine, and this fauna is discussed as well as an English fauna of similar age.

1. These studies were originally intended to form the basis of a world monograph of the Siricidae ; such a work cannot be completed under present circumstances.2. Two ratios are introduced as useful characters for separating species : the ovipositor/forewing ratio and the sawsheath/ovipositor ratio. These ratios were obtained from all specimens of all the species represented in the British Museum collections and the results are tabulated. They were found not to vary with the size of the insects.The former ratio is specially useful in the genus Urocerus, which has a long ovipositor, and the latter ratio in the genus Sirex, which has a shorter ovipositor.3. Keys are given to the genera of the world. Of Semenov's new genera, Xoanon is accepted but not Xanthosirex. A new genus Eriotremex is erected for certain Indo-Malayan species previously included in Tremex.4. Keys are given to the European species, which are compared critically with related species from other parts of the world. A key to the species of Eriotremex, gen. nov., is also given.5. Sirex noctilio, F., and S. juvencus, L., are recorded for the first time from North America and S. cyaneus, F., from the continent of Europe. The common Urocerus of the northern Palaearctic region is shown to be more closely related to the Nearctic U. gigas flavicornis, F., than to the central European U. gigas gigas, L., and is treated as a new subspecies—U. gigas taiganus, subsp. nov. U. gigas tibetanus, subsp. nov., is described from the Himalayas. U. sah, Mocsáry, is treated as a subspecies of U. augur, Klug, and U. cedrorum, Smith, as a synonym of U. augur augur, Klug.6. The British Siricidae are discussed, and it is suggested that U. gigas taiganus, subsp. nov., and the form of S. juvencus, L., with entirely black antennae may be native in the Caledonian forest.7. It is argued that modern Siricidae could not have been derived from the Jurassic Pseudosiricidae.8. The known Oriental and Himalayan Siricidae are listed and discussed. Urocerus multifasciatus, Takeuchi, and Eriotremex formosanus, Matsumura, are mentioned as two species originally described from Formosa but shown also to occur on the mainland. Urocerus niger, sp. nov., is described from the Himalayan region, and the name Eriotremex malayanus, sp. nov., is given to a form described without a name by Forsius from Malaya.9. Several errors in previous work on Siricidae are corrected.
