Als Nachtrag zu "Neophytischs Kultur- und Anbaupflanzen als Kulturflüchtlinge des Rheinlandes" (Adolphi 1995) werden Neufunde und andere neue Beobachtungen mitgeteilt. Zu den bemerkenswerten Erstfunden gehören Malus toringo, Mirabilis jalapa, Morus nigra, Pistia stratiotes, Solidaga x erskinii, Spartium junceum und der Gattungsbastard x Mahoberberis.
Several Coleopterists have been asked to revise the family sections, working from diskettes modified and provided from the original "Beetles of the United States." They will rewrite these sections, and will be recognized as the author of the section. They are asked to sign a writing contract with the publisher. Other Coleopterists have been asked to review the family sections of the new book. These persons are acknowledged in the family section text.
Twenty-two species of Strymon are known from the vicinity of Cacaulandia in Rondonia, Brazil, of which 14 are new species. These belong to 5 species groups: the "oreala" group [Strymon megarus (Godart)]; the "ziba" group [Strymon ziba (Hewitson), Strymon thulia (Hewitson), Strymon spinatus new species, Strymon latamaculus new species, Strymon pallidulus new species, Stlymon tholus new species]; "valentina" group [Strymon rotundum new species]; "crossoea" group [Strymon crossoea (Hewitson), Strymon crambusa (Hewitson), Stlymon germana new species, Strymon novasignum new species, Strymon clavus new species, Strymon implexus new species, Strymon inmirum new species, Strymon incanus new species, Strymon faunalia (Hewitson), Strymon halos new species, Strymon conspergus new species, Strymon bazochii (Godart), Strymon diagonalis new species]; and "eurytulus" group [Strymon bubastus (Stoll)]. Tentative subgroups of species are suggested for the "crossoea" group as they occur in Rondonia. A neotype is designated for Tmolus basilides and the name synonymized with Strymon megarus. The "basilides" group of Johnson et al. (1990) is renamed the "ziba" group. Based on lectotype designations and superficial and genital differences, S. ziba and S. thu.lia are elevated to specific status.
The species of Gigantombra and Angulopis encountered in the Caca ulandia area of central Rondonia, Brazil, are reviewed. These include ten species (all new) of Gigantombra (G. microserrata, G. dl:vergens, G. quadramacula, G. ampla, G. fuscafascia, G. silva, G. rondonia, G. obscura, G. pelplexa, G. pUlpura) and one new species of Angulo pis (A. tenuis). Thecla sangala Hewitson (1868) is recognized as having priority over Theela autoelea Hewitson (1863-1878 [1877]), new synonym. Rondonia continues to appear as a center ofthecline endemism and to provide abundant examples of sibling species diversity.
The Nearctic members of the genus Oetophorus Foerster are revised. There are four species, 0. pleuralis (Cresson), and 0. obscurus, O. clavatus, and O. maculatus, new species. The name Oetophorus stretchii (Cresson) is placed in synonymy with the name Oetophol'us pleuralis (Cresson). Relationships of the genus with others in the tribe Perilissini and relationships of the species included in the genus are briefly discussed.
Verbreitung und Ökologie von Nasturtium x sterile (Airy Shaw) Oef. (Brassicaceae) in Mitteleuropa
(1997)
Anhand der Ergebnisse von Chromosomenzählungen wird die Verbreitung der Nasturtium- Taxa (Brassicaceae) in Mitteleuropa diskutiert. Nasturtium officina/e R. Br. (2n = 32) und Nasturtium microphyllum (Boenn.) Rchb. (2n = 64) sind primär geographisch isoliert, wobei N. officinale seinen Verbreitungsschwerpunkt im südlichen Mitteleuropa hat, während N. microphyllum im nördlichen Mitteleuropa vorkommt. Die natürlichen Areale der Taxa sind durch den ehemaligen Anbau von Nasturtium als Salatpflanze (Brunnenkresse) überlagert. Die hybridogene Nesturtium x sterile (Airy Shaw) Oef. (2n = 48) ist in Mitteleuropa wesentlich weiter verbreitet als bislang angenommen. Die Ergebnisse von Vegetationsaufnahmen und Untersuchungen zum Diasporen-Potential in N. x sterile-Habitaten werden vorgestellt. N. x sterile besiedelt im südwestlichen Niedersachsen vorwiegend regelmäßig ausgeräumte Wiesengräben mit zumindest zeitweise fließendem Wasser. Dieses Taxon verfügt über eine gute vegetative Regenerationsfähigkeit und kann offene Standorte aus dem Diasporen-Potential besiedeln. Eine eventuelle ökologische Differenzierung der Nasturtium- Taxa nach dem Basengehalt des Gewässers wird kritisch diskutiert.
