    Description: The Pterophoridae (Ochyroticinae, Deuterocopinae, Pterophorinae (Tribus: Platyptiliini, Exelastini, Oxyptilini)) species of the Neotropical fauna are reviewed. The species are redescribed. Moths are illustrated in colour for the first time, their genitalia are illustrated in line drawings. The examination of type specimens revealed the presence of four new synonyms: Platyptilia juanvinas Gielis, 1999, is a junior synonym of Platyptilia gravior Meyrick, 1932; Platyptilia jonesi Gielis, 1996, is a junior synonym of Platyptilia semnopis Meyrick, 1931; Oxyptilus maleficus Meyrick, 1926, is a junior synonym of Leptodeuterocopus neales (Walsingham, 1915); Lioptilus parvus Walsingham, 1880, is a junior synonym of Lioptilodes albistriolatus (Zeller, 1871). During the study of much new material 40 new species were discovered: Leptodeuterocopus tungurahue, L. angulatus, L. panamaensis, L. duchicela, Sochchora mulinus, Melanoptilia nigra, Platyptilia spicula, Stenoptilodes maculatus, S. agricultura, S. heppneri, S. medius, S. altiaustralis, Postplatyptilia nebuloarbustum, P. antillae, P. caribica, P. uruguayensis, P. pluvia, P. seitetazas, P. transversus, P. carchi, P. boletus, P, ugartei, P. drechseli, P. corticis, P. zongoensis, P. vorbecki, Amblyptilia landryi, A. kosteri, Lioptilodes altivolans, L. arequipa, L. yungas, L. salarius, L. cocodrilo, Michaelophorus margaritae, M. bahiaensis, Geina integumentum, Capperia browni, Buckleria brasilia, Megalorhipida paraiso, M. dubiosa. In the larger genera the species are arranged in groups. For a distinct group of species a new genus: Melanoptilia is proposed. A comprehensive checklist of the species has been made. To facilitate identification a key is presented to the genus level.

    Description: Two new genera of Entedoninae are described from Afrotropical region. The genus Janicharis gen. nov. (type species: J. africana spec. nov.) is described from Cameroon, Nigeria and Madagascar. The genus Hakuna gen. nov. (type species: H. matata spec. nov.) is described from Uganda. Both genera have a rather characteristic habitus and a peculiar propodeum bearing large anterolateral strips. A new, but yet unnamed, species of the genus Trisecodes Delvare & LaSalle, 2000, is recorded from Cameroon. This is the fi rst Afrotropical record of this genus, originally described from the Neotropical region.

    Description: Dasypoda intermedia spec. nov. from Iran is described. Its description fills a gap of our knowledge of the East Mediterranean fauna of the genus Dasypoda. The West Mediterranean Dasypoda species are well known but the eastern species lack convincing records. Moreover, D. intermedia spec. nov. is a very interesting species from a phylogenetic point of view. It shares some characters common to subgenera Dasypoda s. str. and Megadasypoda Michez, 2004, which provide further evidence for the close relationship of both subgenera.

    Description: Thirty-one species of the family Platystictidae of the Philippines are revised, i.e. all species recognised, excluding the species of the Drepanosticta halterata-group. The following new taxa are described: 16 species in Drepanosticta Laidlaw: D. acuta spec. nov., D. aurita spec. nov., D. centrosaurus spec. nov., D. clados spec. nov., D. flavomaculata spec. nov., D. furcata spec. nov., D. hermes spec. nov., D. krios spec. nov., D. luzonica spec. nov., D. malleus spec. nov., D. myzouris spec. nov., D. paruatia spec. nov., D. pistor spec. nov., D. quadricornu spec. nov., D. rhamphis spec. nov., D. trachelocele spec. nov., two in Protosticta Selys, viz. P. lepteca spec. nov. and P. plicata spec. nov., and three in Sulcosticta gen. nov., viz. S. striata spec. nov., S. pallida spec. nov. and S. viticula spec. nov. The status of eleven previously described nominal taxa is established. One, D. septima Needham & Gyger, is doubtfully considered a synonym of D. mylitta Cowley. Based on a preliminary phylogenetic analysis, the species of Drepanosticta are divided into informal species groups. Most species of the Philippines have affinities to species of Sulawesi, the Moluccas and New Guinea. Several species confined to Palawan have sister-group relationships with species from Borneo. The affinities of various other species confined to the Sulu archipelago, are unsettled as yet. The species of Platystictidae here assigned to Protosticta Selys are presumably not closely related to the type species, P. simplicinervis Selys from Sulawesi. However, a better placement has to await a more detailed phylogenetic study of the family. For three species the new genus Sulcosticta gen. nov. is erected. These species are closely allied based on the structure of the appendages, but should have been assigned to different genera if based on the present generic definitions. Many species here described have small distributional ranges, a common phenomenon in Platystictidae. Since most forests in the Philippines are heavily under threat or have already disappeared in the last fifty years, several taxa described in this paper should be considered under threat of immediate extinction.

    Description: The genus Mama Belokobylskij, 2000 (Braconidae; Euphorinae) is re-assessed and the type species is compared with three similar species: Microctonus cephalicus Provancher, 1886, Microctonus reclinator Ruthe, 1856, and Euphorus spiniscapus Muesebeck, 1936. The results are discussed in relation to the use of taxa based on one specimen (“monotype taxa”). Problems concerning our knowledge of important groups of Euphorinae are outlined. The context of the peculiarly tangled taxonomical situation, which this paper deals with, is considered to be widespread in parasitoid taxonomy, and should be borne in mind in current studies of parasitoid biodiversity assessment.

    Description: The genus Taractrocera is distributed throughout the Oriental and Australian Regions. It contains 16 species, of which two, T. fusca and T. trikora, are described as new in this paper. All species are briefly characterized and the new species are described in full. The phylogeny of the genus is inferred, based on an analysis of morphological and genital characters, both of males and females. The biogeography of the genus is discussed in relation to the phylogeny. The genus has an Australian origin. After some diversification in Australia it dispersed into Asia, in or before the Miocene. It dispersed in the reverse direction, probably before the late-Miocene emergence of the Banda Arc and the Moluccas, 5-6 Mya. Three species are adapted to high altitude, one in the Himalayas and two in New Guinea. Apparently the adaptations occurred independently in the two areas. In New Guinea the high altitude species may have simply been carried up by the Pleistocene and recent uplift of the mountains. Possibly helped by the lowering of the sea-level several times during the Pleistocene, one Australian species colonized some of the Lesser Sunda Islands relatively recently.

    Description: New and lesser-known amphipods of hard substrates in the Delta area of the Netherlands (Crustacea: Amphipoda: Gammaridea) The distribution of 27 new and lesser-known amphipod species of sublittoral hard substrates in the Delta area in the southwest of The Netherlands is described. Data from literature on these species are scarce and/or not readily available. They are supplemented with results from recent investigations of mainly sublittoral hard substrates. Of the 22 marine species only nine occur offshore as well as inshore. The others seem to be restricted to inshore man-made coastline protections. This probably reflects the scarcity of hard substrates further offshore. Four invasive species were recorded in the brackish and freshwater part of the Delta area, two of them of pontocaspian origin.

    Description: The expansion of the range of the spider Argiope bruennichi in the Netherlands (Araneae: Araneidae) Argiope bruennichi (Scopoli, 1772) is one of the biggest and most colourful spiders in Europe and therefore easy to recognise, even by non-specialists. The species has expanded its range in Germany and Belgium for several decades now and reached the south of The Netherlands in 1980. After the discovery of the first female in the south of the province of Limburg more specimens were found in this region in subsequent years. Later the species was discovered near Herkenbosch, about 30 kilometres to the north. Over the last years the expansion continued rapidly and now almost 300 records are brought together. The species has become widespread in the southern and eastern part of The Netherlands. In 1995 a leap of some 70 kilometres was made, from Limburg to the southern parts of the Veluwe. The years 1998 and 1999 were very good for Argiope, both with over 80 records per year. It is suggested that this expansion is related to the warm and sunny summers in the nineties.

    Description: Nests of the carpenter ant Camponotus ligniperda in the northwestern part of its range (Hymenoptera: Formicidae) Camponotus ligniperda (Latreille, 1802) is a rare ant species restricted to the eastern part of the Netherlands. Most records relate to a low number of workers. In this paper the species is reported for the first time from the province of Drenthe. Some ecological features of the groundnest are compared with the only other recent nest in the Netherlands. Both nests are located under a decidious tree which protects them from excessive precipitation. In contrast with reports from Germany and Sweden, nesting sites in buildings and houses are not known. It is suggested that the low chances for settlement in our country are due to the wet atlantic climate as well as competition with larger Formica species.

    Notes: Einige reine Ester und Äther des Vitamins A wurden nach dem von uns früher beschriebenen Aufbauprinzip dargestellt. Die Schmelzpunkte der synthetischen Krystallisate stimmen mit den bekannten Schmelzpunkten der entsprechenden Vitamin-A-Präparate aus Leberölen überein. Die Wirksamkeit der Ester (Standard-β-Carotin) berechnet auf 1 g Vitamin-A-Alkohol betrug 3,3±0,6 Millionen i. E. Der Methyläther besitzt annähernd die gleiche und der Butyläther deutlich geringere Wirksamkeit. Der Phenyläther vom Smp. 90-91° ist wenig wirksam. Die molare Extinktion bei 325-328 mm̈ aller Präparate betrug ca. 50 000 und die molare Extinktion der Carr-Price-Messung gab ebenfalls gleiche Werte. Die molare Exaltation des Systems der konjugierten Doppelbindungen wurde übereinstimmend mit 16,5±0,6 bestimmt. Die Messung der Sauerstoffempfindlichkeit im Warburg-Apparat zeigt, dass die Ester beständiger sind als der Methyläther und der Vitamin-A-Alkohol. Die alkalische Hydrolyse der Ester verläuft erwartungsgemäss als Reaktion 2. Ordnung.

    Notes: Die Aufhebung des Asymmetriezentrums am Kohlenstoffatom 8 durch β-Aminocarbonsäure-Spaltung ergibt ein identisches Lactam aus Lysergsäure und Isolysergsäure, was zur Formulierung dieser Isomeren als Diastereomere führt. Ihre hydrierbare Doppelbindung wird auf Grund des Vergleichs der Absorptionsspektren in Δ9-10 festgelegt. Der Hofmann'sche Abbau, die Decarboxylierung und die Hydrierung von Lysergsäure und Isolysergsäure werden in Übereinstimmung mit dieser Auffassung formuliert. Für den Mechanismus der reversiblen Lysergsäure-Isolysergsäure-Umlagerung wird eine Erklärung gegeben.

Die erwähnte Bestimmungsmethode muss daher durch Zusatz von prothrombinfreiem, aber Faktor V-haltigem Plasma ergänzt werden. Die Angabe der Prothrombinkonzentration in Prozenten der Norm bedarf ebenfalls einer Revision unter Berücksichtigung der Wirkung von Faktor V. Die kritische Prothrombinkonzentration z. B., unterhalb welcher Spontanblutungen zu erwarten sind, liegt nicht, wie bisher angenommen, bei 20, sondern bei 5% Prothrombin.

    Notes: 1. Nach einem kurzen Überblick über die bisher angestellten Untersuchungen über die Landolt-Reaktion wird gezeigt, dass sich drei Typen dieses Vorganges unterscheiden lassen. Diese Aufteilung ergibt sich durch das Geschwindigkeitsverhältnis der drei simultanen Teilreaktionen (1) und (2) und (3). Der Umschlag erfolgt: bei Typ I, wenn das Reduktionsmittel total verbraucht ist (Totalreduktion); bei Typ II, wenn die Geschwindigkeit der Reaktionen (2) und (3) einander gleich werden (partielle Reduktion); bei Typ III, wenn [J'] die Empfindlichkeitsgrenze der Jodstärke-Reaktion erreicht, während Jod schon teilweise ausgeschieden ist (Jod-Vorlauf).

    Notes: 1. Wir haben die Synthese des Citrullins aus Ornithin durch die Mitochondrienfraktion der Leber (Ratte) bei Gegenwart von Glutamin untersucht. Bei Glutaminkonzentrationen von 20-30 μ Mol/cm3 ist das Amid mit oder ohne Zusatz von Ammoniumsalzen der Glutaminsäure plus Ammoniumsalz stark überlegen. Bei kleinen Konzentrationen, unter 3 μ Mol/cm3 liefert aber die Glutaminsäure unter allen Umständen mehr Citrullin als das Glutamin. Es ist also wenig wahrscheinlich, dass das Glutamin eine direkte Zwischenstufe der Synthese ist. Die Wirksamkeit des Amids lässt sich andererseits aber nicht einfach durch die Hydrolyse der Säureamidgruppe erklären. Dieselbe scheint eine spezifische Funktion zu haben. Das Glutamin steht offenbar zu einem Zwischenglied der Citrullinsynthese in enger Beziehung.

    Notes: Zusammenfassend ergibt unsere Untersuchung über im Kindesalter gebildete Harnsteine: 1Im Gegensatz zu den später entstehenden Harnkonkrementen, welche weit bevorzugt Harnsäuresteine darstellen, fehlen Harnsäurebildungen unter den im Kindesalter auftretenden Harnsteinen.2Weit vorherrschend sind vielmehr Struvitsteine wobei diese im Nierenbecken und in den Harnleitern multipel auftreten. In einem Fall hatte sich - offenbar zur Ausnahme ein solitärer Struvitstein in der Harnblase um einen Fremdkörper (Nadel) gebildet. Struvitkonkremente finden sich häufig bei alkalischem Urim mit Cysto-Pyelitis, Oxalat- und Harnsäuresteine dagegen zumeist bei saurem Urin. Struvitsteine können leicht rezidivieren.3Alle Nichtstruvitsteine, nämlich solche aus Csytin, Calciumoxalat-Monohydrat und -Dihydrat, waren Solitärsteine, ersterer in der Harnblase, letztere dagegen im Nierenbecken.

    Notes: 1. Die 4 Carboxylatgruppen des Anions Y-4 der Äthylendiamin-tetraessigsäure liegen in den Komplexionen [MY]z-4 im allgemeinen nicht alle im Zentralatom, so dass dieses noch eine Koordinationslücke aufweist, die einen Fremdliganden aufnehmen kann. Eine dieser Reaktionen, diejenige zwischen CoY-2 und CNS-, wurde mit Hilfe von Extinktionsmessungen untersucht, und es wurde gezeigt, wie man zur Kenntnis der Gleichgewichtskonstanten derartiger Reaktionen gelangen kann.

    Notes: Durch Berücksichtigung aller genannten Regeln erhält man neben den Tabellen I bis III der einfachen Krystallklassen für Oh und Ih die bereits bekannten eindeutigen Charakterendarstellungen der Haupttabellen IV und V. Aus ihnen ergeben sich wiederum die Charakterendarstellungen der Untergruppen O, Th, Td, T bzw. I durch Kolonnenauswahl und Vereinigung der Zeilen mit gleichen zurückbleibenden Charakteren zu einem Typus. Damit ist in fünf Haupttabellen das gesamte Grundmaterial zur Gewinnung der symmetriebedingten Auswahlregeln zusammengefasst. Die nächste Aufgabe ist die der Berechnung der Freiheitsgrade, die in einer dritten Mitteilung erfolgt.

    Notes: L'expérience a montré que, seules jusqu'à présent les techniques d'ozonolyse comportant la réduction de l'ozonide préparé en milieu sec conduisent, pour quelques produits possédant le groupement 〉 C = CH2 générateur d'aldéhyde formique, à des résultats analytiques à peu près satisfaisants. La technique de Doeuvre appartient à cette catégorie. Elle présente divers défauts opératoires et le présent travail a conduit à une micro-méthode exempte de plusieurs de ces défauts. Dans les conditions élaborées, les déterminations de la néo-γ-irone, de plusieurs de ses dérivés, et de l'acide dextro-pimarique, sont satisfaisantes.

    Notes: Reduktion von 20α, 21-Oxydo-17-iso-allopregnan-diol-(3β, 17 β)-monobenzoat-(3) mit Li[AlH4] gab das bekannte 17-Iso-allopregnan-triol-(3β, 17 β, 20α). Durch Hydrierung von 20β, 21-Oxydo-17-iso-allopregnan-diol-(3β, 17β)-monoacetat-(3) mit Li[AlH4] wurde das unbekannte 17-Iso-allopregnan-triol-(3β, 17β, 20β) hergestellt; dieses wurde durch sein Diacetat charakterisiert und seine Konstitution wurde durch Abbau zu Androstanol-(3β)-on-(17) bewiesen. Der bisher als dieses Triol bezeichnete Stoff erwies sich als Gemisch von zwei bekannten Verbindungen. Die früher festgelegte Konfiguration der 17-Iso-allopregnan-tetrole-(3β, 17β, 20,21) wurde durch diese Reaktionen erneut bestätigt.

    Notes: Die Konzentration von freiem Glykokoll und Serin in der Rattenleber lässt sich durch die Ernährung beeinflussen. Der Glykokollgehalt ist bei der Eiweissfütterung gering, während Kohlehydrat-und Fettkost ihn erheblich ansteigen lassen. Das Serin ist nur bei fettreicher Ernährung stark erhöht. Den tiefsten Stand erreicht es bei Eiweissfütterung; bei Kohlehydratfutter und im Hunger wurden mittlere Werte gefunden.

    Notes: Das Alkaloid Corynathein wurde durch Abbau mit Selen in eine Base C19H22N2, das Corynanthyrin, übergeführt. Durch Abbau letzterer Verbindung mit Ozon entstand ein Ozonid C19H22O3N2, das bei der Hydrolyse in ein Keton C19H22O2N2 überging. Letzteres liess sich hydrolytisch zu o-Aminopropiophenon und 3,4-Diäthylpyridin-6-carbonsäure aufspalten. Aus diesen Spaltstücken ergab sich die Konstitutionsformel des Corynanthyrins, die mit jener des Tetrabyrins nahe verwandt ist.

    Notes: Periplogenin wird in 3β,5,14,21-Tetroxy-14-iso-pregnanon-(20) übergeführt. Ausgehend von diesem Tetrol sowie dem bereits beschriebenen 3-Monoacetat wird eine Reihe von Pregnanderivaten bereitet, unter anderem Progesteron, Desoxycorticosteron-acetat, 14-Oxy-14-iso-11-desoxy-corticosteron-acetat. Der letztgenannte Stoff wurde in kleiner Ausbeute bereits früher aus Digitoxigenin bereitet. Er ist mit Corticosteron isomer, erwies sich aber im Everse-de-Fremery-Test als unwirksam.

    Notes: 1. Bei der Umsetzung von Kupferoxyd bzw. Kupfer und Sauerstoff mit den Lösungen der Chloride von Nickel, Kobalt, Magnesium, Zink und Cadmium entstehen basische Doppelchloride der ungefähren stöchiometrischen Zusammensetzung 3 Cu(OH)2, MeCl2. Sie sind isomorph mit dem Kupferhydroxychlorid IIγ. Daraus folgt, dass sie nicht singulären Verbindungen entsprechen, sondern Glieder einer kontinuierlichen Mischkrystallreihe sind, d. h. dass im Kupferhydroxychlorid die Kupfer- durch andere Metallionen ersetzt werden können. Die einfach stöchiometrische Zusammensetzung ist auf die besonderen, bei der Herstellung herrschenden Verhältnisse zurückzuführen.

    Notes: Bei der Kondensation von Äthoxalylketonen bzw. ihrer Natriumenolate mit Chloral entstehen αKeto-β-acyl-γ-trichlormethyl-γ-lactone. Die Konstitution dieser Substanzen ergibt sich auf Grund ihrer Eigenschaften, welche denjenigen einer Reihe früher von uns aus den entsprechenden Äthoxalylverbindungen und Fettaldehyden dargestellter α-Keto-γ-lactone analog sind.

    Notes: Ein Vorversuch zur Synthese optisch aktiver β-Methoxy-adipinsäure aus L-Äpfelsäure lieferte unreine rechtsdrehende Säure, die als Dianilid isoliert werden konnte. Dieses Resultat spricht dafür, dass die bisherigen Raumformeln in der Sterinreihe nicht mit der gebräuchlichen Fischer'schen Definition der Zucker-Reihe Übereinstimmen.
