The trilobiteProtostygina and the composition of the Styginidae, with two new genera

The Styginidae is regarded as an exclusively Ordovician family of trilobites, separate from the Scutelluidae. The hitherto poorly known genusProtostygina Prantl &P?ibyl, 1949 is revised. It is recorded with certainty only from the Llanvirn of the Czech Republic, and the type species is a senior synonym of“Raymondaspis” rubensi rubensi P?ibyl &VANěK, 1968 and“R.” rubensi lybar ?najdr, 1976. Two new styginid genera are proposed:Cyrtocybe, with type species“Raymondaspis” turgida Whittington, 1965, is known from the upper Arenig and lower Llanvirn of Newfoundland, Maine and Norway; andPromargo, with type speciesP.forteyi n. sp., occurs in the Arenig of Newfoundland and Spitsbergen.Turgicephalus Fortey, 1980 is regarded as a junior synonym ofRaymondaspis P?ibyl inPrantl &P?ibyl, 1949. Three genera are excluded from the Styginidae:Kirkdomina Tripp, 1962,Pseudostygina Zhou inZhou et al., 1982 andStyginella P?ibyl &Vaněk, 1971.     

Taxonomische Revision der GattungThelopsis Nyl. (Lichenisierte Fungi)

Die vorliegende Studie enthält Ergebnisse einer taxonomischen Revision der lichenisierten Fungi (Flechten) der GattungThelopsis Nyl. Die Gattung umfasst 6 Arten:Th. flaveola Arnold,Th. isiaca Stiz.,Th. lojkana (Poetsch exArnold)Nyl.,Th. inordinata Nyl.,Th. melathelia Nyl. undTh. rubella Nyl. Bei der Revision waren weder nomenklatorische Änderungen noch Beschreibungen neuer Taxa nötig. Näher wird die systematische Stellung vonThelopsis diskutiert. Im Vergleich mit den Hauptgruppen der lichenisiertenPyrenocarpi nimmtThelopsis, zusammen mit den taxonomisch noch nicht richtig eingereihten Arten“Clathroporina” heterospora Zahlbr. und“Microglaena” rosea Serv., eine systematisch bedeutend isolierte Stellung ein. Demgegenüber existieren reale phylogenetische Beziehungen vonThelopsis zur discocarpen GattungRamonia Stiz. (FamilicThelotremataceae s. ampl.) Es wird vorgeschlagen, die GattungThelopsis in die FamilieThelotremataceae einzugliedern.     

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.     

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.

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.     

Principal component analysis of the relationship between the d-amino acid concentrations and the taste of the sake

We performed sensory evaluations on 141 bottles of sake and analyzed the relationship between the d-amino acid concentrations, and the taste of the sake using principal component analysis, which yielded seven principal components (PC1–7) that explained 100 % of the total variance in the data. PC1, which explains 33.6 % of the total variance, correlates most positively with strong taste and most negatively with balanced tastes. PC2, which explains 54.4 % of the total variance, correlates most positively with a sweet taste and most negatively with bitter and sour tastes. Sakes brewed with “Kimoto yeast starter” and “Yamahaimoto” had high scores for PC1 and PC2, and had strong taste in comparison with sakes brewed with “Sokujo-moto”. When present at concentrations below 50 μM, d-Ala did not affect the PC1 score, but all the sakes showed a high PC1 score, when the d-Ala was above 100 μM. Similar observations were found for the d-Asp and d-Glu concentrations with regard to PC1, and the threshold concentrations of d-Asp and d-Glu that affected the taste were 33.8 and 33.3 μM, respectively. Certain bacteria present in sake, especially lactic acid bacteria, produce d-Ala, d-Asp and d-Glu during storage, and these d-amino acids increased the PC1 score and produced a strong taste (Nojun). When d- and l-Ala were added to the sakes, the value for the umami taste in the sensory evaluation increased, with the effect of d-Ala being much stronger than that of l-Ala. The addition of 50–5,000 μM dl-Ala did not effect on the aroma of the sakes at all.     

A revision ofTaraxacum sect.Piesis (Compositae)

On the basis of allozyme and cultivation data, and of additional herbarium material, a taxonomic and nomenclatural revision ofTaraxacum sect.Piesis A.J. Richards exKirschner et?těpánek is provided. The section is made up of halophilous, sexually reproducing taxa. InT. stenocephalum Boiss. etKotschy,T. pindicum Kirschner et?těpánek, sp. nov., andT. perenne Kirschner et?těpánek, sp. nov., a tetraploid chromosome number has been recorded, representing the only known case of sexuality at the tetraploid level in the genus. The complex ofT. stenocephalum, includes some geographically and morphologically extreme populations treated as subspecies: subsp.gumusanicum (Soest)Kirschner et?těpánek, comb. nov., subsp.magnum Kirschner et?těpánek, subsp. nov., and subsp.daralagesicum (Schischk.)Kirschner et?těpánek, comb. nov. In addition toT. bessarabicum (Hornem.)Hand.-Mazz., a widely distributed Eurasian species,T. stenocephalum, a complex centred in Transcaucasia and Anatolia, andT. pachypodum H. Lindb., a North African endemic, four new species are described:T. salsum Kirschner et?těpánek, sp. nov., a diploid endemic confined to E Crimea,T. perenne Kirschner et?těpánek, sp. nov., a tetraploid sexual species known only from SW Crimea,T. pindicum Kirschner et?těpánek, sp. nov., a remarkable tetraploid endemic to the Pindos Mts., Greece, andT. salsitatis Kirschner, ?těpänek etYirdirimli, sp. nov., an Anatolian diploid species. Furthermore, a hybrid betweenT. salsum andT. bessarabicum from Crimea (documented on the basis of allozyme data elsewhere) is given a binomial,T. xmesohalobium Kirschner et?těpánek, nothosp. nov.
