WEIR'S REQUEST FOR A RULING ON THE INTER¬ PRETATION OF THE NOMINAL SPECIES UNIO PHILLIPSII WILLIAMSON, 1836. Z.N.(S.) 1938 By L. R. Cox (British Museum (Natural History)) In submitting an application that a certain specimen should serve as the standard ofreference for the interpretation of the nominal species Unio pMUipsii Williamson, which (having been founded on a number of specimens) clearly had no holotype, Dr. J. Weir has been faced with the problem that the type-specimen so designated would not comply with the requirements of a lectotype (since there is no proof that would satisfy a judge and jury that it was a syntype, although there is a strong probability that it was one), while it could not become a neotype since there is no proof that would satisfy a judge and jury that all the original syntypes are lost or destroyed. This is but one of many eases where there is no certain evidence (such as the original publication of accurate figures, the citation of registration numbers, or the marking of specimens) that any particular specimen or specimens preserved in the collection of the author of a species must be the holotype or syntypes, for there is always the possibility that specimens were added to the collection subsequent to the description of the species. Apart from recognising and proposing a name for yet another category of type-specimen having the status of a holotype, lectotype, or neotype, it appears that the only solution of this unfortunate difficulty will be to refrain from stipulating that a neotype may be designated only when the original holotype or syntypes are lost or destroyed, and to re-define a neotype as follows:—"A single specimen selected to serve as the ultimate standard of reference for the interpretation of a nominal species when the original holotype or syntypes are lost or destroyed, or cannot be identified with certainty." There could be a recommendation that, in this last contingency, the specimen selected as neotype should come from the collection of the author of the species, if this collection is still in existence. I support Dr. Weir's application that the Manchester Museum specimen L.10106 should be designated as type-specimen of the nominal species Unio pMUipsii and suggest

Łódzki 3, 10-727 Olsztyn, Poland, e-mail: [email protected] ABSTRACT. The study involved the analysis of the foregut content of 120 adult specimens of Colymbetes fuscus and C. striatus collected in aquatic habitats in the Biebrza Marshes (Poland) and the Zehlau Peatbog (Russia). The gut content comprised animals (including eggs of aquatic invertebrates), plants and detritus. Larvae of Ephemeroptera were common in beetles from the Biebrza Marshes. The gut content also included Dytiscidae, Cladocera, Chironomidae and other Diptera, Copepoda, other insects, other Coleoptera aquatica, Heteroptera, Acari, Ostracoda, Culicidae and Asellus aquaticus. In the Zehlau Peatbog, both of the beetle species fed predominantly on the larval stages of Chironomidae (Diptera). The gut content also included adult terrestrial insects and spiders. KEY WORDS: predation, diving beetles, the Zehlau Peatbog, the Biebrza Marshes, Dytiscidae. INTRODUCTION Predation is one of the dominant antagonistic relationships integrating a biocoenosis. In spite of the availability of a rich literature relating to food consumed by predatory insects, our knowledge of the diet of Dytiscidae is still scarce. It is the larval stages of these beetles that seem to have been examined the most thoroughly (JOHANSSON & NILSSON 1992, YOUNG 1967, YOUNG & SPERLING 1986, PEARMAN 1995, LE LOUARN & CLOAREC 1997, GAUTAM & GOUTAM 2006, INODA 2012).

A unified scheme for describing seasonal flight behaviour of highly dispersing primary aquatic insects Article Type: Primary research paper Keywords: flight behaviour, seasonal patterns, year-long dispersal, polarotaxis, Coleoptera, Heteroptera Corresponding Author: Pál Boda Balaton Limnological Institute, Centre of Ecological Research, Hungarian Academy of Sciences Debrecen, HUNGARY Corresponding Author Secondary Information: Corresponding Author's Institution: Balaton Limnological Institute, Centre of Ecological Research, Hungarian Academy of Sciences Corresponding Author's Secondary Institution: First Author: Pál Boda First Author Secondary Information: Order of Authors: Pál Boda Zoltán Csabai Order of Authors Secondary Information: Abstract: Changes of seasonal dispersal flight were investigated based on a wide spectrum of aquatic Heteroptera and Coleoptera species. We hypothesized that species or groups of species can be characterized by various seasonal patterns of dispersal flight. Dispersal activity was studied in a lowland marsh located in NE Hungary during a 30- week long monitoring period. Insects were attracted to highly polarizing horizontal shiny black plastic sheets laid onto the ground. There are no periods of the year (from April till October) when insects are not rising into the air, but species have various seasonal flight activity. Dispersal flight activity of 45 species could be described. These activities assessed based on a seasonal approach and proportional classification. Based on these results three seasonal patterns and twelve sub-patterns were defined. Comparing the observed patterns with previously reported dispersal activity data, we argue that observations found in the literature fit well with patterns defined here, therefore, to assess the dispersal behaviour a unified scheme can be established.

A central feature of the European Water Framework Directive are the reference conditions. The ecological quality status is determined by calculating the distance between the present situation and the reference conditions. To describe reference conditions the natural variation of biota in pristine water bodies should be measured. Because pristine water bodies are not present in the Netherlands anymore, water bodies (springs, streams, rivers and oxbow lakes) in central Poland were investigated. Macrophytes and macroinvertebrates were sampled and environmental variables were measured. The water bodies appeared to have a high biodiversity and a good ecological quality.

The ground plan and comparative morphology of the nymphal head of Membracoidea are presented with particular emphasis on the position of the clypeus, frons, epistomal suture, and ecdysial line. Differences in interpretation of the head structures in Auchenorrhyncha are discussed. Membracoidea head may vary more extensively than heads in any other group of insects. It is often modified by the development of an anterior carina, which apparently was gained and lost multiple times within Membracoidea. The main modifications of the head of Membracoidea and comparison of those changes with the head of other superfamilies of Auchenorrhyncha are described. INTRODUCTION MATERIAL AND METHODS The general morphology of the insect head is relatively Dried and pinned specimens were studied under an Olympus well studied (Ferris, 1942, 1943, 1944; Cook, 1944; SZX12 microscope with SZX-DA drawing tube attachment. DuPorte, 1946; Snodgrass, 1947; Matsuda, 1965; Detailed study of internal structures and boundaries of sclerites Kukalová-Peck, 1985, 1987, 1991, 1992, 2008). There is based on examination of exuviae and specimens cleared in are also a few papers in which the hemipteran head is 5% KOH.
