Foraminifera from the Silberberg Formation («Lower Oligocene») at Silberberg,near Helmstedt (Germany)

From the Silberberg Quarry, type locality of the Silberberg Formation (Martini &Ritzkowski 1968), some planktonic foraminifera are described:Globigerina officinalis Subbotina, Globigerina ouachitaensisHowe &Wallace,G. praebulloides leroyi Blow &Banner, G.praebulloides occlusa Blow &Banner which taxa are here suggested to form intergrading morphotypes within the range of variation of a population dominated byG. officinalis. In addition,G. cf.danvillensis Howe &Wallace is found. The planktonic fauna, together with some elements in the benthonic fauna, suggests a possible correlation with the Danville Landing Member of the Jackson Formation, Louisiana, traditionally ascribed to the Upper Eocene. There is some similarity with European Uppermost Eocene — Lower Oligocene faunas described by various authors. The Silberberg Formation was suggested to be a Neostratotype for the Latdorfian Stage of the Lower Oligocene byMartini &Ritzkowski (1968). It is suggested that the Silberberg Formation may well be coeval with the Upper Priabonian as proposed byCita 1969.     

Retiolitid graptolites from the collection of HermannJaeger in the Museum für Naturkunde, Berlin (Germany). I.Neogothograptus andHoloretiolites

Isolated material of Ludlow (Upper Silurian) retiolitid graptolites are described from isolated material in theJaeger collection of the Museum für Naturkunde (Humboldt Universität Berlin, Germany). This material from glacial erratic boulders of northern Germany has never been published, even though it yields important structural information for retiolitid taxonomy. The astogeny and formation of the clathrial and reticular lists ofNeogothograptus andHoloretiolites rhabdosomes is discussed in some detail. New species includeNeogothograptus ornatus n. sp. andNeogothograptus eximinassa n. sp. Hermann Jaeger recognized both species as new and named them in his collection, but not publish the material.Neogothograptus thorsteinssoni Lenz &;Kozlowska-Dawidziuk andNeogothograptus romani Koz?owska-Dawidziuk have been recognized for the first time in north German glacial erratic boulders.     

Taxonomic status of the belemnite genusBelemnopsis Bayle 1878

The Tethyan genus “Belemnopsis” of authors, notBayle 1878, includes 110–120 Bajocian to Hauterivian belemnite species and subspecies from Europe and the southern hemisphere. Its type species,Belemnites sulcatus Miller 1826 from the Callovian to Oxfordian of England, belongs to the Boreal belemnite genusLagonibelus Gustomesov 1956, since Phillips selected a lectotype for it in 1870. But the subsequent designation of the type species byDouvillé in 1879 is invalid according to Art. 67 (h) ICZN, and consequentlyBelemnopsis Bayle gets a nomen dubium. It is also a homonym ofBelemnopsis Edwards inGray 1849, and has, therefore, to be replaced byPachybelemnopsis Riegraf 1980, a junior subjective synonym, the family Belemnopseidae Naef 1922 by MesohibolitidaeNerodenko 1983, and the suborder BelemnopseinaJeletzky 1965 by PachybelemnopseinaRiegraf inRiegraf et al. 1998.     

Parasites of rice stemborers in Sarawak (Malaysian Borneo)

Observations on parasites were made during a study of the following rice stem-borers in Sarawak (Malaysian Borneo):Tryporyza incertulas (Walker),T. innotata (Walker),Chilo suppressalis (Walker)C. auricilia (Dudgeon), andSeamia inferens (Walker). Egg-parasitism was often high, but that of the larval and pupal stages generally very low. Between 40–80% of theTryporyza eggs were parasitised byTelenomus rowani (Gahan), while 30–50% were attacked byTetrastichus schoenobii Ferrière. About 40–90% of the eggs ofChilo were parasitised byTrichogramma? japonicum Ashmead and 5–26% byTelenomus dignus (Gahan). Only 0.4–3% of theTryporyza larvae were parasitised by a Braconid,Rhaconotus schoenobivorus (Rohwer), whileBracon chinensis Szepligeti attacked 0.2–0.7% of the larvae ofC. suppressalis. Parasitism ofSesamia larvae byApanteles flavipes Cameron was equally low, never exceeding 2%. Pupal parasitism was somewhat higher.Tetrastichus israeli (Mani & Kurian) attacked 8% and 18% of the pupae ofC. suppressalis andS. inferens, respectively, while the Ichneumonid,Xanthopimpla stemmator (Thunberg) attacked up to 3% of the pupae of the former species. The immature stages of some of these parasites are described.     

Ein Beitrag zur Nomenklatur sphinctozoider Schwämme (Porifera)

The sphinctozoid sponge generaFania Senowbari-Daryan 1990 andSpica Termier &Termier 1977 are preoccupied.Fania is replaced byFanthalamia nom. nov. andSpica by the younger synonymFistulispongia Termier &Termier 1977. The invalid subfamily name FaniinaeSenowbari-Daryan 1990 is replaced by Fanthalamiinae n. subfam. The invalid family and subfamily names SpicidaeTermier &Termier 1977 and SpicinaeSenowbari-Daryan 1990 respectively are replaced by FistulispongiidaeTermier atTermier 1977 and FistulispongiinaeSenowbari-Daryan 1990. The generaWaagenium de Laubenfels 1957 andCatubria Merla 1931 were previously overlooked.Waagenium DeLaubenfels 1957 is a younger synonym ofColospongia Laube 1865. The position ofCatubria Merla 1931 is uncertain. Most probablyCatubria is an alga.     

The species ofPlatygastridae [Hymenoptera,Proctotrupoidea] in the collection of the «Naturhistorisches Museum» in Vienna with special reference to the types ofForster

For the study of the taxonomy ofPlatygastridae it is necessary to know the location and other data of the types of older authors. This is already known for most of the species described by English and American authors (Masner, 1965, 1966, 1969 andMasner & Muesebeck, 1968), but must still be done for those described byFörster, Haliday, Thomson, Westwood, Kieffer and others. In this paper I give a list of the types ofFörster's species ofPlatygastridae in the “Naturhistorisches Museum” in Vienna. In the same collection I found many original species described by other authors, of wich the location was not known. These species can be very important in solving some taxonomic problems. A list of them is included in this paper.     

Bucania (Gastropoda) from the Ordovician of Estonia

Seven species ofBucania Hall 1847 from the Ordovician of Estonia are presented, also taking into consideration Pleistocene drift material from Germany, and their stratigraphical and geographical distributions are revised. The Middle Ordovician speciesBucania latissima Koken 1897 andBucania salpinx Koken 1897 are tentatively assigned toMegalomphala Ulrich inUlrich &Scofield 1897, while the Lower Ordovician speciesBucania macera Koken inKoken &Perner 1925 is placed inSalpingostoma Roemer 1876. The Middle OrdovicianBucania czekanowskii (Schmidt 1858) and the Upper OrdovicianBucania radiata (d’Eichwald 1856) were earlier considered conspecific, but based on study of the type material they are here considered distinct species.Salpingostoma cornu (Koken 1897), commonly referred to this genus because of the trema, is here transferred toBucania. Two Upper Ordovician specimens ofBucania display wide and abruptly flaring apertures morphologically far removed from other species of the genus.     

Polyploidy and variation in theCampanula rotundifolia complex. Part II. (Taxonomic) I. Revision of the groupsSaxicolae,Lanceolatae andAlpicolae in Czechoslovakia and adjacent regions

A survey is given of three natural groups of the subsectionHeterophylla (Witas.)Fed. of the genusCampanula L. Within theSaxicolae four taxa of higher rank have been revealed:c. xylocarpa Kovanda (2n=34),C. gentilis Kovanda (2n=34),C. moravica (Spitzner)Kovanda subsp.moravica (2n=68), andC. moravica subsp.xylorrhiza (O. Schwarz)Kovanda (2n=102). BothAlpicolae andLanceolatae are represented by a single species: the first byC. cochleariifolia Lam. (2n=34), the latter byC. serrata (Kit. ap.Schult.)Hendrych (2n=34). Cytology, ecology and geographical distribution of all these taxa have been reviewed, and relationships to the other members of the complex discussed. Infraspecific variation within each species has also been examined.     

Etagement des algues et des invertébrés sessiles dans l'Archipel de Glénan

The Glénan Archipelago was investigated, from the surface to a depth of 60 m, byScuba diving. Four distinct communities (“peuplements”) have been determined that fit into the system of zonation defined by the Genoa Symposium (1957). The results are compared with observations made in the English Channel (Cabioch 1968) and in the Atlantic Ocean (Glemarec 1971). Since illumination depends upon the angle of the rocky face, photophilic species exhibit a maximum range when the rock surfaces are horizontal. The sublittoral zone is dominated by laminarians. They form two distinct communities with the animal and vegetal species they overshadow. The upper community is characterized byLaminaria digitata (Linné)Lamouroux (horizontal rocky face from 0 to 6 m; vertical rocky face from +0.5 to ?3 m). The lower cummunity, characterized byL. hyperborea (Gunner)Foslie has a greater vertical extension (horizontal: ?6 m to ?26 m; vertical: ?3 to ?30 m). The circalittoral zone is colonized by several animal species growing in a ramified manner: the upper community is characterized by Axinellidae (?30 m), the lower byDendrophyllia cornigera (Lamarck) (?55 to ?60 m). Upright algae disappear somewhere between ?40 and ?47 m.     

Redescription of the largest trigonotarbid arachnid —Kreischeria wiedei Geinitz 1882 from the Upper Carboniferous of Zwickau, Germany

Kreischeria wiedei Geinitz 1882 (Arachnida: Trigonotarbida) from the Upper Carboniferous (Westphalian D) of Zwickau, Germany is redescribed. The family KreischeriidaeHaase 1890 is reinstated and rediagnosed to accomodate this species. We provisionally refer the speciesAnzinia thevenini (Pruvost 1919),Gondwanarachne argentinensis Pinto &Hünicken 1980,Hemikreischeria geinitzi (Thévenin 1902),Pseudokreischeria pococki Gill 1924 andPseudokreischeria varia Petrunkevitch 1949 to Kreischeriidae too.     

Notes on some African hepatic genera 1–5

The present study deals with five genera of hepatics in Africa, Isotachis Mitt., Anastrophyllum (Spruce) Steph., Tritomaria Schiffn. ex Loeske, Gymnocoleopsis (Schust.) Schust. and Lophozia (Dum.) Dum. All African populations of the genus Isotachis Mitt. are considered to be one species, I. aubertii (Schwaegr.) Mitt. Four species of Anastrophyllum (Spruce) Steph. (s.l.), A. auritum (Lehm.) Steph., A. piligerum (Nees) Spruce, A. subcomplicatum (Lehm. et Lindenb.) Steph. and A. minutum (Schreb.) Schust., and two species of Tritomaria Schiffn. et Loeske, T. camerunensis S. Arnell and T. exsecta (Schrad.) Schiffn. ex Loeske occur in Africa. Gymmocoleopsis multiflora (Steph.) Schust. represents a genus and species hitherto unreported for the African flora. Finally, five Lophozia (Dum.) Dum. species, L. argentina (Steph.) Schust., L. capensis S. Arnell, L. decolorans (Limpr.) Steph., L. hedbergii S. Arnell and L. tristaniana (S. Arnell) Váňa, are reported from central and southern Africa; two of these (L. argentina (Steph.) Schust. and L. decolorans (Limpr.) Steph.) represent the first reports from Africa.     

Inoceramids from Kreibitz-Zittauer area (Saxony and northern Bohemia): revision ofAndert’s (1911) descriptions

Andert’s (1911) inoceramids (Bivalvia) from the topmost Turonian and Lower and lowermost Middle Coniacian (Cretaceous) of the Kreibitz-Zittauer area (Saxony and northern Bohemia) are revised, partially redescribed and newly illustrated. Ten species are discussed. Of the forms described as new byAndert,Inoceramus weiset is shown to represent deformed representatives ofCremnoceramus crassus (Petrascheck), andI. winkholdioides Andert should probably be synonymized withC. brongniarti (Mantell).Andert’s interpretation ofFlegel’s (1904) species, i.e.I. frechi andI. glaziae, is not correct; the former should be referred toMytiloides scupini (Heinz), while the latter includesC. inconstans (Woods),I. vistulensis Walaszczyk,C. rotundatus (Tröger nonFiege), andM. cf.turonicus Walaszczyk. The speciesI. subquadratus Andert representsC. rotundatus (Tröger nonFiege), and hisI. cuvieri var.planus is referred toC. inconstans (Woods) and toC. cf.transilvanicus (Simionescu). The speciesI. protractus Scupin is referred toC. waltersdorfensis (Andert). The main source localities toAndert (1911), i. e. Sonnenberg near Waltersdorf and “Dachsloch” quarry near Innozenzidorf (Czech: Lesne), are of latest Late Turonian/Early Coniacian (theMytiloides scupini andCremnoceramus rotundatus Zones) and late Early Coniacian (C. deformis- C. crassus Zone) age respectively. The third locality, i. e. railway cutting at Tannenberg station (Czech: Jedlová), is probably or late Early Coniacian or early Middle Coniacian age.     

Chromosome counts and chromosome morphology of some selected species

In the years 1976–1981 we studied chromosome counts and karyotypic formulae of the following 29 species of plants from 41 localities (of these 6 from Bohemia, 32 from Moravia, 3 from Slovakia):Batrachium baudotii (Godron) F. W. Schultz,Chenopodium rubrum L.,C. polyspermum L.,C. murale L.,C. ficifolium Sm.,C. opulifolium Schrader ex DC. inLam. et DC.,C. strictum Roth [subsp.strictum, subsp.glaucophyllum (Aellen)Aellen inJust etAellen, subsp.striatiforme Uotila],Arenaria grandiflora L.,Illecebrum verticillatum L.,Spergula morisonii Boreau inDuchartre,Spergularia marginata (DC. inLam. et DC.)Kittel S. marina (L.)Griseb.,S. rubra (L.) J. etC. Presl,Silene conica L.,Sisymbrium loeselii L.,S. volgense Bieb. exE. Fourn.,S. orientale L. [subsp. orientale, subsp.macroloma (A. Pomel)Dvo?ák],S. officinale (L.)Scop.,Descurainia sophia (L.)Webb exPrantl inEngler etPrantl,Nasturtium officinale R. Br. inAiton,Barbarea arcuata (Opiz inPresl J. et C.)Reichenb.,Lunaria annua L.,Soldanella montana Willd.,S. carpatica Vierh. inUrban etGraebner,Lotus tenuis Waldst. etKit. exWilld.,L. uliginosus Schkuhr,Trigonella monspeliaca L.,Geranium sibiricum L.,Lactuca tatarica (L.)C.

Biological control of the beanfly,Ophiomyia phaseoli [Dipt.: Agromyzidae], byOpius spp. [Hym.: Braconidae] in the Hawaiian Islands

Attention is drawn to the transfer of the beanfliesMelanagromyza phaseoli (Tryon) andM. spencerella Greathead to the genusOphiomyia Braschnikov bySpencer (1973). The confusion over the nomenclature of theOpius spp. parasites is discussed and it is shown that the namesO. phaseoli Fischer andO. importatus Fischer should be used. Their introduction into Hawaii and establishment is briefly discussed in relation to their effectiveness as biological control agents. It is shown that they show a high degree of consistency of parasitism which has resulted in an acceptable degree of control ofOphiomyia phaseoli although there is no evidence that they act in a density dependent manner.     

Upper Triassic (Keuper) non-marine trace fossils from the Haßberge area (Franconia, south-eastern Germany)

Various trace fossils from the Hassberge Formation and the Löwenstein Formation (Middle Keuper, Upper Triassic) of the Haßberge region are described. Twenty-three different forms have been identified, 17 of which are named, includingCruziana pascens n. isp.,Lockeia cunctator n. isp., andRusophycus versans n. isp.Lockeia siliquaria James, 1879,L. amygdaloides (Seilacher, 1953),L. triangulichnus Kim, 1994, andL. elongata (Yang, 1984) are revised and synonymized under the oldest available name,L. siliquaria James, 1879.Rusophycus eutendorfensis (Linck, 1942) andR. carbonarius Dawson, 1864 are revised. The diagnosis ofPolykladichnus Fürsich, 1981 is emended, and a diagnosis forHelminthoidichnites Fitch, 1850 is given for the first time. Among the described ichnotaxa,Skolithos ispp.,Rusophycus carbonarius, andTaenidium barretti are the most common forms. The trace fossil association is typical of theScoyenia ichnofacies, which indicates non-marine, periodically or completely inundated environments, such as floodplains and lake margins. Two palaeoichnocoenoses are identified. One ichnocoenosis, dominated byCruziana problematica, cf.Polykladichnus isp., andSkolithos isp. B characterizes margins of trough cross-bedded sandstones. Another ichnocoenosis, dominated byRusophycus versans n. isp.,Taenidium barretti,Scoyenia gracilis andSkolithos isp. A is related to ephemeral lake deposits. Taxonomic recommendations for the use of hitherto described and figured invertebrate Keuper trace fossils from Germany are given.     

New internally structured decapod microcoprolites from Germany (Late Triassic/Early Miocene), Southern Spain (Early/Middle Jurassic) and Portugal (Late Jurassic): Taxonomy, palaeoecology and evolutionary implications

Fossil faecal pellets with internal structures are described from non-marine environments for the first time. In the Late Triassic Lehrberg Beds (Middle Keuper, Carnian) of Germany, the oldest stratigraphic record of the form genusHelicerina Brönnimann &Masse,Helicerina keuperina Seegis n. sp., occurs.Favreina kalankyra Ebli from the Norian Hauptdolomit Formation is also attributed to this genus. Another new speciesof Helicerina, H. ruttei Schweigert n. sp., is described from the Early Miocene calcareous freshwater tufas of Southern Germany. It is attributed to the brachyuran freshwater crabProballaya quenstedti (Zittel) which occurs abundantly at the same locality. Hence, the coprolite genusHelicerina is the product of brachyuran decapods or their Triassic ancestors, and not of anomuran decapods as thought before. From younger Early to Middle Jurassic pelagic ferrugineous limestones of the Subbetic area (Southern Spain), the new speciesFavreina belandoi Fels n. sp. is described besidesHelicerina siciliana Senowbari-Daryan, Schäfer &Catalano, and the better known speciesPalaxius salataensis Brönnimann, Cros &Zaninetti. The number of canals withinFavreina belandoi varies but is clearly correlated with different ontogenetic stages of the same producer. From the Late Jurassic of Portugal, the new speciesPetalina hexalunulata Leinfelder n. gen. n. sp. is reported. It co-occurs withFavreina prusensis (Paréjas). The new genusPetalina is distinct fromFavreina by its hemispherical cross sections of the canals. In Portugal, both species are restricted to intrajurassic marine karstic fissures of the reefal Ota Limestone.
