Lower Cambrian tubular micro-to macrofossils from the Paseky Shale of the Barrandian area (Czech Republic)

The carbonaceous megafossil (mega-alga)Marpolia spissa Walcott 1919 is described from the Early Cambrian of the Barrandian area for the first time. Macroscopic remains of colonies ofM. spissa are compared with tubular microfossils of the same rocks. Different areas in colonies ofM. spissa are assignable to several (part-based) genera and species of microfossils. Therefore, the microfossil taxaSiphonophycus robustum (Schopf 1968)Knoll et al. 1991,S. typicum (Hermann 1974)Butterfield 1994,S. kestron Schopf 1968,S. capitaneum Nyberg &Schopf 1984,Polytrichoides lineatus Hermann 1974, emend.Knoll et al. 1991,Tortunema angusta (Kolosov 1984)Butterfield 1994 andTortunema wernadskii (Schepeleva 1960)Butterfield 1994 should only be used as form-species in the sense of an artificial taxonomy. The palaeoenvironment of the Paseky Shale and the biological assignment ofMarpolia spissa are discussed.

Notes on the biology ofBrachymeria [Neobrachymeria] nosatoi and its importance in the control ofNephantis serinopa

Nephantis serinopa Meyrick is now known to be parasitised by six species ofBrachymeria, viz.,B. nephantidis Gahan,B. lasus Walk.,B. excarinata Gahan,B. (Neobrachymeria) nosatoi Habu,B. euploeae Westw., andB. hime attevae Joseph Of these,B. (N.) nosatoi is the most effective pupal parasite ofN. serinopa in Kerala. Certain aspects of the biology of this parasite have been studied.     

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.     

A revision of the moss genusCrossidium (Pottiaceae) with the description of the new genusMicrocrossidium

A world revision of the genusCrossidium Jur. recognizes 11 species, which are described and discussed in the context of important taxonomic characters. An identification key is provided.C. asirense Frey & Kürschner is reduced to synonymy withC. davidai Catcheside, and the geographical range ofC. laevipilum Ther. & Trab. is extended to Europe. Phylogenetic trends are interpreted on the basis of two main evolutionary lines associated with the presence or absence of hyaline hair-points on the leaves. A twelfth species is transferred toMicrocrossidium Guerra & Cano, gen. nov., asM. apiculatum (Magill)Guerra & Cano, comb. nova, because of differences in stem anatomy, peristome configuration, and spore morphology.     

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.     

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.     

LignicolousHyphomycetes from Czechoslovakia 8.Endophragmiella andPhragmocephala

Thirteen species and one variety ofEndophragmiella Sutton and three species ofPhragmocephala Mason etHughes collected by the author in Czechoslovakia, and occasionally in other regions of Europe are described and illustrated. Four new species and one new variety are described inEndophragmiella—E. aseptata Hol.-Jech.,E. fatrensis Holt.-Jech.,E. ramificata Hol.-Jech.,E. similis Hol.-Jech. andE. uniseptata (Ellis) Hughes var.pusilla Hol.-Jech..     

Rubus ambrosius (Rubus subsect.Rubus, Rosaceae), a new bramble species from the eastern part of Central Europe

Rubus ambrosius Trávní?ek etOklejewicz, a widely distributed species from the eastern part of Central Europe (Czech Republic, Slovakia and Poland), is described.R. ambrosius differs from similar speciesR. sulcatus Vest by more deeply furrowed stems, longer prickles on first-year tems, longer petioles, more prickly petioles, densely hairy leaves beneath and by blunter leaf margin serration with incisions only (2-)1.5–2.5 mm deep. The newly described species is illustrated both by photographs (including the holotype) and a line drawing. A list of localities and a distribution map are presented.     

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.     

LignicolousHyphomycetes from Czechoslovakia 5.Septonema,Hormiactella andLylea

Three genera of lignicolousHyphomycetes Septonema Corda,Hormiactella Saac. andLylea Morgan-Jones are discussed. Illustrations and determination keys are provided. Five species ofSeptonema—S. fasciculare (Corda) Hughes,S. leptaleum (Ellis & Harkn.) Hughes,S. pinicola Hol.-Jech.,S. secedens Corda andS. laricium Hol.-Jech.—and two species ofHormiactella—H. fusca (Preuss) Sacc. andH. asetosa Hol.-Jech.—have been found in Czechoslovakia. A new speciesS. pseudobinum Hol.-Jech. is described from Romania.Septonema tetracoilum (Corda Hughes is accommodated in the genusLylea Morgan-Jones.     

The Vegetation of Prokop Valley nature reserve in Prague

A survey of the present vegetation of the Prokop Valley Nature Reserve revealed the following natural communities:Erysimo crepidifolii-Festucetum valesiacae Klika 1933,Alysso saxatilis-Festucetum Klika 1941,Allio montani-Sedetum albi Klika 1939,Helianthemo cani-Caricetum humilis ass. nova,Helianthemo cani-Seslerietum calcariae Klika 1933,Primulo veris-Seslerietum calcariae Zlatník 1928,Prunion spinosae Soó (1931) 1940 em.Tx. 1952,Prunion fruticosae Tx. 1952,Scabioso ochrolecae-Brachypodietum pinnati Klika 1932,Salvio nemorosae-Melicetum transsilvanicae ass. nova,Lathyro versicoloris-Quercetum pubescentis Klika 1932,Geranio-Peucedanetum cervariae (Kuhn 1937)Th. Müller 1961,Galio-Carpinetum Oberdorfer 1957,Aceri-Carpinetum Klika 1941,Luzulo-Quercetum (Hilitzer 1932)Passarge 1953,Genistion Böcher 1943,Mentho-Juncetum inflexi Lohmeyer 1953. For the anthropogenic vegetation another group of units was used. The species composition, environmental relationships an area of distribution are given for every mapping unit; characteristic soil properties for most important units of natural vegetation are also discussed.     

Geographical distribution ofAphidiidae [Hym.] imported to California for biological control ofAcyrthosiphon kondoi andAcyrthosiphon pisum [Hom.: Aphididae]

A survey forAcyrthosiphon kondoi Shinji and its insect enemies was conducted in 1976–1977 in Afghanistan, Belgium, Czechoslovakia, Greece, Iran, Israel and Maroc. The search was concentrated in areas having cultivated species ofMedicago. A. kondoi was found only in Afghanistan, and in Iran. It was not found inMedicago-growing areas west from Iran, but it has been reported from India and Japan. Aphidius ervi Haliday,Aphidius urticae group,Praon barbatum Mackauer andAphidius smithi Sharma & Rao, were reared fromA. kondoi constituting new parasite records. New parasite and locality records were also found forA. urticae group,A. smithi andP. barbatum onAcyrthosiphum pisum (Harris). In laboratory trials, all cultures of parasitesA. ervi andP. barbatum readily parasitized and reproduced onA. kondoi onLens esculenta Moench. Cultures ofA. urticae group andA. smithi oviposited on, but did not complete development of immatures in,A. kondoi onL. esculenta. Hyperparasites identified as species includedAsaphes suspensus (Nees),Asaphes vulgaris Walker,Aphidencyrtus aphidivorus (Mayr),Dendrocerus breadalbimensis (Kieffer),Dendrocerus carpenteri (Curtis), andPachyneuron aphidis (Bouche). Available data suggest the origin of distribution ofA. kondoi may be Central Asia, and that populations ofA. ervi may be most suitable for colonization programs againstA. kondoi.     

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.
