Chroococcopsis epiphytica n. sp., eine neue Cyanophycee aus dem Gebiet des Neusiedler Sees

The morphology and life history ofChroococcopsis epiphytica nova spec. is described, a German and Latin diagnosis is added. Cultivated plants display some differences in comparison with plants in their natural habitat: calcification occurs only in the natural medium, endosporangia are developed only by cultivated plants. At the basis, where single cells and thalli are attached, a special sort of jelly is produced; it is discernible only by elective staining with methylene blue. The systematic position of the new species is discussed.

     

Sauertylenchus labiodiscus n. gen., n. sp., from Australia (Nematoda:Tylenchorhynchinae)

Sauertylenchus labiodiscus n. gem, n. sp. is described and illustrated from soil around Rhagodia sp. in Australia. It can be distinguished from the most closely related genus Tylenchorhynchus Cobb, 1913 by the distinctly set-off, rounded, lip region with a conspicuous labial disc, and long thin stylet. The face view and spicules of Sauertylenchus labiodiscus are illustrated with scanning electron micrographs. The subfamilies Tylenchorhynchinae and Merlininae ale discussed.     

Marionina istriae n. sp., ein mariner Enchytraeide (Oligochaeta) aus dem mediterranen Hygropsammal

A new enchytraeid worm,Marionina istriae n. sp. (Oligochaeta), is described from the marine supralittoral of an island near Rovinj (Yugoslavian coast of the Adriatic Sea). The position of the new species within the genusMarionina is discussed. A short diagnosis of the new species is given by a diagrammatic illustration of some taxonomically important anatomical features. The discussion includes some considerations on the relevance of brain size and arrangement of blood vessels for enchytraeid systematics.     

<Emphasis Type="Italic">Rheiacardia lerami</Emphasis> n. gen. n. sp., ein hippocardiider Rostroconch aus dem Devon Laurussias

To the most recent revisions of the family HippocardiidaePojeta &; Runnegar (Rostroconchia, Mollusca) the additional, monotypic genusRheiacardia n. gen. is added. The genus belongs to the recently described subfamily HippocardiinaePojeta &; Runnegar and is unambiguously classified and characterized by differentiation from the previously described genera of the subfamily.Rheiacardia n. gen. has a stratigraphic occurrence from Early to Middle Devonian.     

Eremotyle affixa,n. gen., n. sp., eine neue Protococcale (Chlorophycee)

Ohne ZusammenfassungDie Veröffentlichung dieser Untersuchungen fällt zusammen mit der Feier des 70. Geburtstages Prof. Dr.Franz Ruttners. Der Verf. möchte nicht versäumen, mit seinem Glückwunsch dem Jubilar auch seinen herzlichsten Dank auszusprechen: hat er ihm doch zuerst als Student, später als junger Dozent, endlich als Kollege vielerlei Arten von Belehrung, Anregung und Förderung zu verdanken. Mögen diese Zeilen der Erinnerung an manche gemeinsam verlebte Stunden gewidmet sein!     

Paleoleishmania proterus n. gen., n. sp., (Trypanosomatidae: Kinetoplastida) from Cretaceous Burmese amber

A trypanosomatid (Trypanosomatidae: Kinetoplastida) associated with a blood-filled female sand fly in Cretaceous Burmese amber, is described in the new genus and species, Paleoleishmania proterus. The genus Paleoleishmania is established as a collective genus for digenetic fossil trypanosomes associated with sand flies. Amastigotes, promastigotes and paramastigotes are described. Paleoleishmania proterus is the first fossil kinetoplastid and provides a minimum age for the digenetic Trypanosomatidae. Its discovery indicates that vector-borne pathogens had been established by the Early Cretaceous.     

Review of grylloblattid insects (Insecta: Grylloblattida) from the Solikamsk deposits of the Perm Region

The Solikamsk faunas of the Vorkuta series of the Pechora Basin and the Solikamsk Formation of the Perm Region of Russia are reviewed. New taxa are described from Tyul’kino locality (Solikamsk District): Artinska ufimica sp. nov., Sylvaprisca tyulkinensis sp. nov., Ufimoprisca gen. nov. (the type species Sylvaprisca alba Aristov, 2005), U. mica sp. nov., U. kamensis sp. nov. (family Lemmatophoridae), Sylvaella ovalis sp. nov. (family Liomopteridae), Ivakhosara prima sp. nov., and Megakhosarella prisca sp. nov. (family Megakhosaridae). Additionally, Uralioma sp. is described from Shchugor locality (Cherdyn’ District). Two species, Paraprisca solikamskensis Aristov, 2009 (family Lemmatophoridae) from Tyul’kino and Kolvidelia curta G. Zalessky, 1950 (family Ideliidae) from Pokcha locality (Cherdyn’ District)), are redescribed.     

A new genus and species of Baetidae from Sri Lanka (Ceylon): Indocloeon primum gen.n., sp.n. (Insecta,Ephemeroptera)

The nymph of a new genus and species, Indocloeon primum gen.n., sp.n. from Sri Lanka is described, distinguishing characteristics are illustrated. This new genus is most closely related to Cloeon Leach and Centroptilum Eaton. Indocloeon gen.n. possesses a unique combination of morphological characters and two derived characters.     

Favreina peruviensis n. sp., ein Crustaceen-Mikrokoprolith aus dem lias von peru

From the Liassic of Peru a crustacean microcoprolite association comprisingParafavreina thoronetensis andFavreina peruviensis n. sp. is described. Due to the well preserved material it can be shown, that in cross-sectionParafavreina thoronetensis has both triangular and crescent-shaped canals.     

Saetheriella amplicristata gen. n., sp. n., a new Orthocladiinae (Diptera: Chironomidae) from Tennessee

The generic diagnosis of the male imago of a new genus of the subfamily Orthocladiinae (Chironomidae), Saetheriella is given. The genus is characterized by protruding, hairy eyes; antenna with straight, apical seta; antepronotum reduced; squama without setae; Cu₁ distinctly downcurved; and anal point short, triangular, covered with microtrichia and with two strong, lateral setae. The genus is close to Gynnidocladius Sublette & Wirth, Unniella Sæther and Parakiefferiella Thienemann. The distribution of the genera shows evidence of a Gondwanian connection. The male imago of the only included species S. amplicristata sp. n. is described.
