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.     

Taxonomie und Systematik der HippocardioideaPojeta & Runnegar, 1976 [n. superfam.] (Mollusca; Rostroconchia)

The revisions of the families PseudobigaleaidaeHoare, Mapes &; Yancey, 2002 and HippocardiidaePojeta &; Runnegar, 1976 led to the introduction of a new taxon at the superfamily rank in order to unite the two families and distinguish them from the members of the Conocardiidae and Bransoniidae within the order Conocardiida. The autapomorphy of this new superfamily HippocardioideaPojeta &; Runnegar, 1976 [n. superfam.] — the more or less uniform development of at least one hood — is considered taxonomically as so important that we exclude a common ancestry of the almost contemporaneously occurring taxa of the Hippocardiidae, Pseudobigaleaidae on the one hand and the Bransoniidae sensuPojeta &; Runnegar on the other. The family Hippocardiidae is divided into six taxa on subfamily rank, the HippocardiinaePojeta &; Runnegar, Babinicardiinae n. subfam., Barrandeicardiinae n. subfam., Bohemicardiinae n. subfam., Goticardiinae n. subfam. and Hassiacardiinae n. subfam. At the species level, 13 taxa are assigned to the generaBabinicardia n. gen.,Barrandeicardia n. gen.,Bohemicardia n. gen.,Filicardia n. gen,.Globocardia n. gen.,Goticardia n. gen.,Pohlia n. gen. andHassiacardia n. gen. Additionally, the speciesGoticardia kauffmannii n. gen. n. sp. is introduced, whereas the primary homonymy of ?Conocardium“reticulatum Babin, 1966 is retained, because this taxon remained inassignable to any of the existing genera, but is considered as a member of the Hippocardiidae. The revised family Hippocardiidae occurred stratigraphically from the Middle Silurian (Wenlockian) until Mississippian time; members of the new superfamily Hippocardioidea are known from the Ordovician until the Pennsylvanian.     

Einige nicht-foliicole Arten der FamilieEctolechiaceae (Lichenes) aus Brasilien

Here 13 species of the nonfoliicolous species of the lichen familyEctolechiaceae Zahlbr. em.Haf. are reported, which were found in a collection from Brazil. Six species are described as new:Badimia corticola (sp.n.),Calopadia isidiosa (sp.n.),C. psoromoides (sp.n.),C. subfusca (sp.n.),Tapellaria corticola (sp.n.), andT. schindleri (sp.n.). Seven species have been identified with earlier described species:Calopadia chacoënsis (Malme) comb. n. (=Lopadium chacoënse Malme),C. foliicola (Fée) Vězda,C. fusca (Müll. Arg.) Vězda,C. lecanorella (Nyl.) comb. n.,C. perpallida (Nyl.) Věda,C. phyllogena (Müll. Arg.) Vězda, andTapellaria epiphylla (Müll. Arg.) Sant. A key and illustrations for all studied species are provided, and the nomenclatural problem of the correct generic name of thePyrenotrichum Mont. (anamorph) forCalopadia Vězda orTapellaria Sant. (teleomorphs) are discussed.     

Revision der Familie HippocardiidaePojeta & Runnegar, 1976 (Mollusca; Rostroconchia)

Following the revision and integration of the family PseudobigaleaidaeHoare, Mapes &; Yancey into the existing systematic concept of the rostroconch order Conocardiida the original family of hood-carrying rostroconchs, the HippocardiidaePojeta &; Runnegar, is revised and subdivided in this contribution. Here, we present the members of the subfamily HippocardiinaePojeta &; Runnegar [n. subfam.]. Its erection appeared necessary first, as the family Hippocardiidae had been used for decades as a conglomeration taxon where most varied morphotypes were assigned to the type genusHippocardia, whose character combinations only just now can be distinguished, and secondly because the number of hood-carrying hippocardiid rostroconch taxa increased markedly during our studies. Ten taxa at the species level are assigned to the generaHippocardia Brown, 1843,Bieberiana n. gen.,Cartericardia n. gen.,Fraipontia n. gen.,Hoareicardia n. gen. andPojetorum n. gen. All the taxa are precisely diagnosed and described at the subfamily, genus and species level by a uniform, revised and completed terminology of morphologic characters. This allows comparability of the taxa and aids in the reconstruction of phylogenetic relationships in the Hippocardiinae [n. subfam.], whose members occur from the Late Silurian until the Mississippian.     

Notes on some African hepatic genera 6–9

The present study deals with African species ofSyzygiella Spruce,Allisoniella Hodgs. andGymnomitriaceae Klinggr. Three species ofSyzygiella Spruce,S. geminifolia (Mitt.) Steph.,S. concreta (Gott.) Spruce and one indeterminable species with orbicular leaves (known only in sterile condition) occur in Africa.Allisoniella nigra (Rodw.) Schust. represents a genus hitherto unreported for the African flora. The present knowledge ofGymnomitriaceae Klinggr. in subsaharan Africa is summarised; five species ofMarsupella Dum., one ofGymnomitrion Corda and five ofHerzogobryum Grolle are reported. Finally, some additions to the generaIsotachis Mitt.,Anastrophyllum (Spruce) Steph. andLophozia (Dum.) Dum. are presented.     

Foliikole Flechten der Insel Kuba

About 78 foliicolous lichen species were found in a lichen collection from Cuba. Five of these species are established as new taxa:Porina cubana sp. n.,P. pocsii sp. n.,P. subpilosa sp. n.,Tricharia cubana sp. n. andBacidia ekmanii sp. n. Three new combinations are proposed:Phylloporis multipunctata (Merr. exR. Sant.) comb. n. (bas.:Porina multipunctata Merr. exR. Sant.),Phylloporis plytypoda (Müll. Arg.) comb. n. (bas:Porina platypoda Müll. Arg.) andCalenia aspidota (Vain.) comb. n. (bas.:Ectolechia aspidota Vain.). Taxonomic notes are provided for some taxa, and brief phytogeographical comments are supplied for all the treated species.     

Première découverte d’un squelette de Channidae (Poisson téléostéen) dans le Miocène inférieur d’Illerkirchberg, près d’Ulm (Wurtemberg, Allemagne)

A skeleton of a Channid fish is reported for the first time from the European Lower Miocene. Because of the lack of any appropriate diagnostic character, it is nevertheless impossible to determine if it belongs either to the Asiatic genusChanna Scopoli or to the African one,Parachanna Teugels &Daget. For this reason, its palaeobiogeographical significance remains unclear. Otoliths (sagitta) that very likely belong to the same Channid species have been described from Illerkirchberg asChanna elliptica (vonSalis). They are compared to the sagitta from recent species of the generaChanna (Scopoli) andParachanna (Teugels &Daget). Their morphological characters are intermediate between those characterizing the sagitta of both genera.

Two new Indian species ofCentrodora Foerster, 1878 [Hymenoptera: Aphelinidae] parasitic in the eggs of Membracids [Homoptera: Membracidae)

The Aphelinid genus,Centrodora Foerster, is recorded for the first time from India, and two new species (C. azizi sp. n.,C. mumtazi sp. n.) are described. These were reared from the eggs of the Membracid generaOtinotus Buckt. andOxyrachis Germ.     

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.     

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.     

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.     

Annotated chromosome numbers of selected asiaticPotentilla species
