Neue Nerillidae (Archiannelida) aus dem Sublitoral der IMordsee und des Mittelatlantik (Nordwest-Afrika)

Bathynerilta marina gen. et sp.n., Bathychaetus heptapous gen. et sp.n. (both off the east coast of Scotland), and Afronerilla hartwigi gen. et sp.n. (off the coast of Mauretania) are described; all from the sublittoral. The main features of Bathynerilla marina are: 8 segments with capillary setae; parapodial cirri on each segment; without anal cirri. The features of Afronerilla hartwigi are: 8 segments with capillary setae; without palps, tentacles, and anal cirri; the parapodial cirri on segment 1 and 8 are absent. The main features of Bathychaetus heptapous are: a pharyngeal bulb with a pair of cuticulary jaw-like structures; 7 segments with capillary setae; parapodial cirri on each segment present; without tentacles.

Neue Ostracoden aus dem Kimmeridgium NW-Deutschlands

In the course of systematic investigations of Kimmeridgian ostracod assemblages in NW-Germany some so far undescribed taxa have been discovered [Fabanella kimmeridgiensis n. sp.,Dicrorygma (Orthorygma?) dimorpha n. sp.,Rectocythere (Rectocythere) paehgei n.sp.,Marslatourella (Gigantourella) ventripennata n.sp.], which are formally described in this paper.

Zygopleuroidea (Gastropoda) aus dem Lias und Dogger Deutschlands und Nordwestpolens

16 taxa of gastropods are described from the Lower and Middle Jurassic of Germany and northwestern Poland. They belong to seven genera. Two species (Pommerozygia aspera, Costazygia bilzi) and two genera (Brevizygia, Costazygia) are new. The family Pommerozygiidae is new as well. Compared to the Zygopleuridae, the Pommerozygiidae have a rather short and broad shell with only few teleoconch whorls. The protoconch is broad conical with a rounded apex (because the first whorls are nearly planispiral). From the Zygopleuridae only members of the Zygopleurinae have been found. Most Jurassic species have a smooth protoconch. Within the Zygopleuridae, the development possibly began with protoconchs carrying collabral axial ribs (and spirals) and led to smooth protoconchs. The genera of the Pommerozygiidae are rather similar to each other. The planktotrophic larval shell has a subsutural row of nodes like many species of Triassic Zygopleuridae. Therefore, both families are closely related. The Pommerozygiidae are possibly a separate branch of the Zygopleuroidea without descendants. The main branch is probably the evolutionary line Zygopleuriidae — Janthinoidea.     

Neue Taxa vonTillandsia subgenusDiaphoranthema (Bromeliaceae) aus Bolivien und Argentinien

5 new taxa are described and illustrated; their position within the subgenus is discussed:T. hirta W. Till & L. Hromadnik,T. cotagaitensis L. Hromadnik,T. caliginosa W. Till, andT. gilliesii Baker subsp.polysticha W. Till & L. Hromadnik are members of a group includingT. myosura Grisebach exBaker,T. mandonii E. Morren exMez in DC.,T. retorta Grisebach exBaker em.Grisebach andT. andicola Gillies exBaker. T. brealitoensis L. Hromadnik is related toT. angulosa Mez in DC. but distinct and possibly of hybrid origin.

     

Neue und interessante Arten aus dem Miozän von Salzhausen im Vogelsberg

The investigations of the Salzhausen (Vogelsberg/Western Germany) brown coal materials held in some museums have shown new and interesting species which complete the picture of an autochthonous Mastixioidea-flora from the middle Miocene age. Fruits and seeds of the families Ulnaceae, Moraceae, Betulaceae, Actinidiaceae, Tiliaceae, Rosaceae, Lythraceae, Cornaceae, Nyssaceae, Mastixiaceae, Rhamnaceae, Vitaceae, and Araceae have been described. New species are Gironniera verrucata Mai, Morus germanica Mai, Swida discimontana Mai, Ziziphus striata (Ludwig) Mai et Gregor, Ampelopsis malvaeformis (Schlotheim) Mai, Parthenocissus langsdorfii Mai, Epipremnum avimontanum Gregor, and E. salzhausense Gregor. A revised register of the fossil flora contains about 60 species positively idenitfied. Particular ecological conditions the “carpolithes coal”-formation with its accumulation of fruits and seeds have brought into effect, whereas the dysodil-like brown coal is discernable as a stillwater formation.     

Neue elemanolide und guajanolide aus Zinnia-arten

The investigation of three Zinnia species afforded thirteen new elemanolides. Though these compounds could be separated only in part, the spectroscopic data clearly indicate the proposed structures. Furthermore, four new guaianolides were isolated. The chemotaxonomic situation is discussed briefly.     

Neue sesquiterpene und acetylenverbindungen aus Cineraria-arten

The investigation of several members of the South African genus Cineraria affords, in addition to known compounds, several new eremophilene derivatives together with modified types all derived from a carbon skeleton where the 5-methyl has migrated to C-6. Some of these compounds are transformed to unusual enol lactones. Furthermore some derivatives of himachalene are present. All species also contain C₁₁-acetylenes, most of which are new. Senecio deltoideus also contains some of these compounds. The chemotaxonomic situation is discussed.     

Neue diterpene und germacranolide aus Mikania-Arten

From three Mikania species, three new labdanic acid and two kaurenic acid derivatives have been isolated together with known compounds and four new germacranolides, differing only in the ester moiety.
