  • New Record of Haplotaxis Gordioides (Oligochaeta:Haplotaxidae) from Hungary and Its Occurrence in Tap Water
    FOLIA HISTORICO NATURALIA MUSEI MATRAENSIS 1997 22: 81–83 New record of Haplotaxis gordioides (Oligochaeta:Haplotaxidae) from Hungary and its occurrence in tap water MICHAEL E. SMITH – SÁNDOR ANDRIKOVICH – DÁVID MURÁNYI ABSTRACT: Four specimens of Haplotaxis gordioides (Oligochaeta:Haplotaxidae) were collected on 10 January 1998 and 21 February 1998 from unfiltered, unchlorinated indoor tap water in Járdánháza, Heves- Borsodi Hills, Hungary. Morphological characteristics are discussed. This is the first reported collection of Haplotaxis gordioides in Hungary. Haplotaxid worms are primitive oligochaetes (BRINKHURST, 1984, 1992, 1994), found primarily in groundwater. The family has a cosmopolitan distribution, but many species are restricted to specific locales or habitats (BRINKHURST, 1978; BRINKHURST & JAMIE- SON, 1971). Also, because haplotaxids are rarely collected, detailed distribution patterns for most individual species are lacking. BRINKHURST and JAMIESON (1971) described the distribution of Haplotaxis gordioides as Holarctic and he listed several areas of Europe where it has been, or is expected to be found (BRINKHURST, 1978). The oligochaete fauna of Hungary is poorly known (FERENCZ, 1979). To date, Haplotaxis gordioides has not been collected from Hungary, although it was included in keys by AND- RÁSSY (1955) and FERENCZ (1979) as potentially occurring in the oligochaete fauna of the region. The purpose of this paper is to report the collection of Haplotaxis gordioides for the first time from Hungary and to provide information on some morphological characteristics. CLASS Oligochaeta ORDER Haplotaxida FAMILY Haplotaxidae Haplotaxis gordioides (Hartmann, 1821) Two immature worms were collected 10 January 1998 in indoor tap water from a private groundwater well serving six residences in the village of Járdánháza, Heves-Borsodi Hills, Hungary.

    NEW RECORDS OF CHIRONOMIDAE (DIPTERA) FROM CONTINENTAL FRANCE Joel Moubayed-Breil Applied ecology, 10 rue des Fenouils, 34070-Montpellier, France, Email: [email protected] Abstract Material recently collected in Continental France has allowed me to generate a list of 83 taxa of chironomids, including 37 new records to the fauna of France. According to published data on the chironomid fauna of France 718 chironomid species are hitherto known from the French territories. The nomenclature and taxonomy of the species listed are based on the last version of the Chironomidae data in Fauna Europaea, on recent revisions of genera and other recent publications relevant to taxonomy and nomenclature. Introduction French territories represent almost the largest Figure 1. Major biogeographic regions and subregions variety of aquatic ecosystems in Europe with of France respect to both physiographic and hydrographic aspects. According to literature on the chironomid fauna of France, some regions still are better Sites and methodology sampled then others, and the best sampled areas The identification of slide mounted specimens are: The northern and southern parts of the Alps was aided by recent taxonomic revisions and keys (regions 5a and 5b in figure 1); western, central to adults or pupal exuviae (Reiss and Säwedal and eastern parts of the Pyrenees (regions 6, 7, 8), 1981; Tuiskunen 1986; Serra-Tosio 1989; Sæther and South-Central France, including inland and 1990; Soponis 1990; Langton 1991; Sæther and coastal rivers (regions 9a and 9b).

  • Chironominae 8.1
    CHIRONOMINAE 8.1 SUBFAMILY CHIRONOMINAE 8 DIAGNOSIS: Antennae 4-8 segmented, rarely reduced. Labrum with S I simple, palmate or plumose; S II simple, apically fringed or plumose; S III simple; S IV normal or sometimes on pedicel. Labral lamellae usually well developed, but reduced or absent in some taxa. Mentum usually with 8-16 well sclerotized teeth; sometimes central teeth or entire mentum pale or poorly sclerotized; rarely teeth fewer than 8 or modified as seta-like projections. Ventromental plates well developed and usually striate, but striae reduced or vestigial in some taxa; beard absent. Prementum without dense brushes of setae. Body usually with anterior and posterior parapods and procerci well developed; setal fringe not present, but sometimes with bifurcate pectinate setae. Penultimate segment sometimes with 1-2 pairs of ventral tubules; antepenultimate segment sometimes with lateral tubules. Anal tubules usually present, reduced in brackish water and marine taxa. NOTESTES: Usually the most abundant subfamily (in terms of individuals and taxa) found on the Coastal Plain of the Southeast. Found in fresh, brackish and salt water (at least one truly marine genus). Most larvae build silken tubes in or on substrate; some mine in plants, dead wood or sediments; some are free- living; some build transportable cases. Many larvae feed by spinning silk catch-nets, allowing them to fill with detritus, etc., and then ingesting the net; some taxa are grazers; some are predacious. Larvae of several taxa (especially Chironomus) have haemoglobin that gives them a red color and the ability to live in low oxygen conditions. With only one exception (Skutzia), at the generic level the larvae of all described (as adults) southeastern Chironominae are known.

Die am weitesten verbreitete Art ist Asellus ( Asellus) aquaticus (L., 175 8); sie ist ein sibirisches Faunenelement, das sich postglazial nach Westen hin ausgebreitet hat (BrRSTEIN 1951; WILLIAMS 1962). Weitaus weniger häufig tritt die zweite Art, Proasellus coxalis (Dollfus, 1892), auf; diese im übrigen circummediterran verbreitete Art ist in Mittel­ europa mit der Unterart septentrionalis (Herbst, 1956) vertreten, die vermutlich erst in jüngster Zeit eingeschleppt worden ist (HERHAUS 1977). Am seltensten ist auf deutschem Boden die dritte Art, Proasellus meridianus (Racovitza, 1919). P. meridianus ist eine autochthon west­ europä,isch-atlantische Form (GRUNER 1965); in Deutschland wurde sie von STAMMER (1932) am linken Niederrhein nachgewiesen. Für die sichere Bestimmung der drei Arten ist die Untersuchung der Pleopoden II unter dem Binokular unerläßlich.

ABSTRACT. A reevaluation of South American oligochaetes produced 871 known species. Megadrile earthworms have rates of endemism around 90% in South America, while Enchytraeidae have less than 75% endemism, and aquatic oligochaetes have less than 40% endemic taxa in South America. Glossoscolecid species number 429 species in South America alone, a full two-thirds of the known megadrile earthworms. More than half of the South American taxa of Oligochaeta (424) occur in Brazil, being followed by Argentina (208 taxa), Ecuador (163 taxa), and Colombia (142 taxa).

  • Spatial and Temporal Distribution of Aquatic Insects in the Dicle (Tigris) River Basin, Turkey, with New Records

Larvae, pupae, pupal exuviae, and nymphs of insects were obtained from samples collected by a plankton net monthly during a 1-year period in 2008 and 2009 at seven different sites of the Dicle (Tigris) River Basin. A total of 35 taxa from the orders Trichoptera (1 taxon), Ephemeroptera (3 taxa), and Diptera (31 taxa) were identified. Chironomidae (Diptera) was the most diverse group and was represented by three major subfamilies, namely Tanypodinae (2 taxa), Orthocladiinae (19 taxa), and Chironominae (7 taxa). Among these species, Nanocladius (Nanocladius) spiniplenus Saether, 1977 is a new record for Turkey as well as for western Asia. In addition, the Psychomyia larvae found for the first time in the Dicle (Tigris) River Basin (Turkey) were described. Both taxa have been illustrated to warrant validation. Taxa number varied spatially from 6 to 14 and temporally from 2 to 12 during the sampling period. Along the river, Cricotopus bicinctus and Orthocladius (S.) holsatus were the most common taxa. Key words: Diptera, Ephemeroptera, Trichoptera, Insecta, Dicle (Tigris) River 1.
