Domiciliary cockroaches and their oothecal parasites in India

In a survey for oothecal parasites of cockroaches in India, 6 species of cockroaches were recorded. Of theseNeostylopyga rhombifolia (Stoll.) was restricted to thatched huts whileBlattella germanica (L.),Periplaneta americana (L.),P. australasiae (F.),P. brunnea Burmeister andSupella longipalpa (F.) were common in other types of buildings. Eight species of parasites, of which 4 are new records, were reared:Anastatus tenuipes Bolivar.,Comperia merceti Compere,Evania appendigaster (L.),Evania sp. nearantennalis Westw., Genus et sp. nov. nearAnastatus. Tetrastichus asthenogmus (Waterston),T. hagenowii (Ratzeburg) andTetrastichus sp. (miser group) which is hyperparasitic. The natural and experimental hosts of these parasites are discussed. The low levels of field parasitism suggest there is scope for introducing more promising parasite species into India for biological control of cockroaches.     

LignicolousHyphomycetes from Czechoslovakia 6.Spadicoides andDiplococcium

Seventeen species belonging toSpadicoides Hughes andDiplococcium Grove collected in Central Europe mostly in Czechoslovakia are described and illustrated. Two new species are described inSpadicoides—S. carpatica Hol.-Jech.,S. penatium Hol.-Jech. and three new species inDiplococcium—D. bicolor Hol.-Jech.,D. insolitum Hol.-Jech. andD. parcum,Hol.-Jech.     

Cytotaxonomic study ofTragopogon L. in czechoslovakia

Karyotypes ofTragopogon orientalis L. subsp.orientalis, T orientalis L. subsp.leiocarpos (Sauter)Trnka,T. pratensis L.,T. minor Miller,T. dubius Scop. subsp.dubius andT. dubius Scop. subsp.major (Jacq.)Vollmann were studied. The occurrence in Slovakia ofT. pratensis was karyologically proved.     

Karyological and taxonomic observations onDracocephalum foetidum Bunge andKoenigia islandica L.

Chromosome numbers are reported for two Mongolian species,Dracocephalum foetidum Bunge (2n=12) andKoenigia islandica L. (2n=14). The relationship ofD. foetidum toD. moldavica L. (2n=10) and some patterns of phenotypic variation inK. islandica are briefly discussed. The following new combinations are proposed:K. cyanadra (Diels) Měsí?ek etSoják,K. forrestii (Diels) Měsí?ek etSoják,K. hubertii (Lingelsh.) Měsí?ek etSoják, andK. nummularifolia (Meisn.) Měsí?ek etSoják.     

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.     

Reclassifications and new names for some European Phanerogams

On the basis of taxonomic and nomenclatural revisions of various plant groups 37 new nomenclatural combinations are proposed mostly for European phanerogamous taxa (21 for species, 14 for subspecies, 2 for hybrids.)Medicula Medicus,Pseudofumaria Medicus andThlasidia Rafin. are accepted as taxonomically justified genera and correct generic names.Dactylorhiza longebracteata (F. W. Schmidt)Holub is proposed instead ofD. fuchsii (Druce) Soó, andHylotelephium triphyllum (Haworth) Holub isstead ofH. purpureum (L.)Holub.     

The systematic significance of seed morphology and anatomy in thePortulacaceae (Centrospermae)

Nyananyo B. L. (1988): The systematic significance of seed morphology and anatomy in thePortulacaceae (Centrospermae).—Folia Geobot. Phytotax., Praha, 23: 275–279.—The seeds of 115 species in eighteen genera of the familyPortulacaceae were examined with the scanning electron microscope. Longitudinal sections of seeds of representatives of all the genera were examined with the light microscope. Two broad groups based on shape of the seeds, ornamentation of the external surface of their testa, and the position of the embryo relative to the endosperm were recognised. The first group comprising three genera:Anacampseros L.,Grahamia Gillies andTalinopsis A. Gray, have seeds which are pyriform with wings and trichomes, and an embryo that is more or less parallel to the endosperm, while the second of fifteen genera:Calandrinia H.B.K.,Calyptridium Nuttall,Calyptrotheca Gilg,Ceraria Pearson etStephens,Claytonia L.,Lenzia Philippi,Lewisia Pursh,Lyallia Hooker fil.,Montia L.,Portulaca L.,Portulacaria Jacquin,Silvaea Philippi,Talinella Baillon,Talinum Adanson, andWangerinia Franz, are reniform without wings and with an embryo that is horse-shoe shaped around the endosperm.     

The parasite complex ofSaissetia nigra in Malaysia

The percentage parasitism ofSaissetia nigra (Nietner) by chalcidoid parasites and the relative abundance of individual parasites were studied in the field usingHibiscus rosa-sinensis L. as the host plant. In order of abundance (on the basis of percentage recorded) the primary parasites wereAnysis saissetiae Ash.,Aneristus ceroplastae How., andMicroterys newcombi (Gir)., while the hyperparasites wereMarietta exitiosa Comp.,Cheiloneurus saissetiae Noyes & Chua andEupelmus catoxanthae Ferr. The efficiency ofA. saissetiae (the larvae of which feed on the scale eggs) to control the scale population is doubtful because it is often parasitised by all 3 hyperparasites mentioned and each larva during development causes only 58% egg mortality of the parasitised host, leaving many scale eggs unconsumed.A. ceroplastae appears to be more useful parasite because it attacks the 2nd instar scales which cause significant damage to the host plant and it is free from attack by hyperparasites.     

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.     

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.     

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.     

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.     

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.     

Potentilla L. sect.Rivales Wolf and related taxa in the Baltic states

Morphological variation ofPotentilla norvegica L.,P. heidenreichii Zimmeter andP. supina L. usually treated within the sectionRivales Wolf,P. recta L. (sect.Rectae Wolf),P. canescens Bess.,P. argentea L. s.l.,P. collina Wibel (sect.Argenteae Wolf) andP. goldbachii Rupr. (sect.Chrysanthae Wolf) was studied using multivariate statistical methods. According to k-means clustering,P. canescens stands closer toP. heidenreichii of the sect.Rivales than toP. argentea. P. collina, the other representative of sect.Argenteae, is not connected withP. canescens at all. Therefore,P. canescens should belong to sect.Rivales and not to sect.Argenteae. InPotentilla argentea s.l.,P. impolita Wahlenb.,P. argentea L. var.argentea, var.decumbens (Jord.)Lehm., var.demissa (Jord.) Lehm., var.grandiceps (Zimmeter) Rouy etE.G. Camus and var.tenerrima (Velen.) Wolf were identified.P. impolita specimens did not cluster out into a separate cluster as didP. collina, P. canescens andP. heidenreichii, but formed mixed clusters with different varieties ofP. argentea s.str. Therefore,P. impolita is not worthy of the rank of species and evidently not even that of subspecies, and should be treated as a variety—P. argentea var.incanescens (Opiz) Focke.     

New names inPhanerogamae 2

New nomenclatural combinations are proposed, necessitated mostly by the adoption of a narrower concept of the generic classificatory unit or, in some cases, by necessary changes of the taxonomic rank in several taxa. Explanatory comments on the taxonomic and nomenclatural problems are provided in the following genera:Aegonychon S. F. Gray (Lithospermum L. p.p.),Anemonastrum Holub andAnemonoides Mill. (Anemone L. p.p.),Bromopsis Fourr. (=Bromus L. p.p.),Calathiana Delarbre (Gentiana L. p.p.),Calcitrapoides Fabr. (Centaurea L. p.p.),Ciminalis Adans. (Gentiana L. p.p.),Pistolochia Bernh. (Corydalis Vent. p.p.),Psyllium Mill. (Plantago L. p.p.) andTephroseris (Reichenb.)Reichenb. (Senecio L. p.p.). In all 300 new combinations are proposed, including 17 inAnemonastrum, 32 inAnemonoides, 70 inBromopsis, 13 inCalathiana, 13 inCalcitrapoides, 29 inPistolochia, 40 inTephroseris and 25 inXanthoxalis.

Parasites of bark beetles [Col.: Scolytidae] on pine and cypress in Israel

Ten species of hymenopterous parasites were reared from logs of pine and cypress, naturally infested with 5 species of bark beetles,viz., Orthotomicus erosus Woll.,Pityogenes calcaratus Eichh., andTomicus destruens Woll. — on pine;Phloeosinus armatus Reitt. andP. aubei Perris — on cypress, in Israel. The parasites were:Dendrosoter chaenopachoides Rusch,D. hartigii (Ratz.),D. middendorfi (Ratz.),D. protuberans Nees (Braconidae), Eurytoma morio Boheman (Eurytomidae), Cerocephala eccoptogastri Masi,Heydenia pretiosa F?rster,Metacolus unifasciatus F?rster,Rhaphitelus maculatus Walker andRoptrocerus xylophagorum (Ratz.) (Pteromalidae). The most common wereM. unifasciatus on pine and cypress,D. chaenopachoides andR. xylophagorum on pine, andD. protuberans on cypress, occurring in samples collected during most seasons. Less common wasE. morio, which was reared from both conifers.D. middendorfi was found on pine, and only during winter. The other species were found only occasionally.     

Selected chromosome counts of the Czechoslovak flora III

Chromosome numbers compared with as yet published data are given for the following 12 Phanerogams (both native species and aliens) from Czechoslovakia:Ambrosia trifida L.,Cardamine chelidonia L.,Dephne cneorum L.,Epipactis albensis Nováková etRydlo,Linum flavum L.subsp flavum, Lunaria rediviva L.,Nepeta grandiflora M.BIEB.,Reseda luteola L.,Thlaspi montanum L.,Tithymalus salicifolius (Host)Klotzsch etGarcke,Tithymalus virgultosus (Klokov) Holub andVerbascum speciosum Schrad. subsp.speciosum. The chromosome number 2n=40 is presented for the first time in autogamousEpipactis albensis Nováková etRydlo. New chromosome numbers were found inCardamine chelidonia L. (2n=32) and inTithymalus salicifolius (Host) Klotzch etGarcke (2n=40). Known but less frequent cytotypes are reported inLinum flavum L. subsp.flavum (2n=28) and inVerbascum speciosum Schrad. subsp.speciosum (2n=30).     

Notes on the incidence and biology of some parasites of the pine cone-borers in Pakistan

Trichogrammatoidea sp. nov.,Telenomus sp.?kolbei Mayr (egg parasites),Liotryphon sp.,Lissonota sp. nr.deversor Gravenhorst,Zemiotes sp. (larval parasites) andDibrachys sp. nr.affinis Masi (pupal parasite) parasitized the pine cone-borersCateremna cedrella Hamp.,Dioryctria abietella (Schiff.),Cydia ethelinda Meyr. andEucosma pylonitis Meyr. in Pakistan. The incidence and some aspects of the life-history of these parasites are briefly described.L. sp. nr.deversor andZemiotes sp. were more common throughout the investigation areas.
