We simultaneously considered morphology and molecular phylogeny to modify the generic classification of the ‘pyropterine clade’ (Lycidae, Erotinae, Dictyopterini). To place species previously included in Benibotarus Kôno, 1932 in reciprocally monophyletic genera, we propose Gomezzuritus gen. nov. with the type-species Dictyopterus alternatus Fairmaire, 1856. Further, we transfer Gomezzuritus alternatus (Fairmaire, 1856) comb. nov., G. longicornis (Reiche, 1878) comb. nov., and G. rubripes (Pic, 1897) comb. nov. from Benibotarus to Gomezzuritus gen. nov. The pyropterine clade contains five genera in the Palaearctic region: Pyropterus Mulsant, 1838, Gomezzuritus gen. nov., Helcophorus Fairmaire, 1891, Greenarus Kazantsev, 1995, and Benibotarus Kôno, 1932. The arrangement of longitudinal elytral costae proved misleading for consideration of relationships. Two genera in distant positions share only four primary costae (Pyropterus and Helcophorus), and three similarly distant genera share the shortened primary costa 3, resulting in three primary and four secondary longitudinal costae (Gomezzuritus, Greenarus, and Benibotarus). The larva of Gomezzuritus alternatus is described in detail, and it is compared with the larvae of other Dictyopterini, including the presumed larva of G. longicornis.
Die Tiefsee macht mehr als zwei Drittel der Erdoberfläche aus und sie beherbergt wahrscheinlich mehr als die Hälfte aller Arten auf der Erde. Und doch ist über diesen riesigen Lebensraum bislang nur wenig bekannt. Die Zoologin Angelika Brandt untersucht die uns weitgehend fremde Tierwelt der dunklen Tiefe – und hat dabei herausgefunden, wie sehr diese durch den Klimawandel und durch die anderen globalen Auswirkungen menschlichen Handelns bedroht ist.
The interactions between the lacewing Ceraeochrysa claveri (Navás) (Neuroptera: Chrysopidae) larva and the coconut mealybug Nipaecoccus nipae (Maskell) (Hemiptera: Pseudococcidae) were recorded. The third-instar lacewing larva constructed a dorsal packet using mealybug wax from both male pupal cases and the bodies of adult females. Surprisingly, live nymphs were also frequently placed into the dorsal packet. Prey mealybugs were discarded and not incorporated into the packet after consumption. When disturbed, adult female mealybugs reflex bled from their dorsal ostioles, contacting the mouthparts of the lacewing. The lacewing quickly retreated to clean the mouthparts on the substrate, providing further evidence that ostiolar fluids act as a defense mechanism for mealybugs. Despite repeatedly contacting the ostiolar fluid, the lacewing pupated and eclosed successfully. Macro video footage of dorsal packet construction and ostiolar reflex bleeding is included. This is the first report of C. claveri preying on N. nipae, the first evidence of C. claveri using mealybug wax to construct the dorsal packet, and the first account of reflex bleeding via the dorsal ostioles to deter predators in N. nipae.

Die öffentliche Dauerausstellung mit Bildern von Barbara Klemm auf dem Campus Westend hat Zuwachs bekommen: 44 neue Fotografien zeigen Motive von Auslandsreisen der langjährigen F.A.Z.-Fotografin. Damit erhält die bisherige Ausstellung im Bereich Studium, Lehre, Internationales (SLI) der Goethe-Universität auch Bilder zum Thema »Internationales«.
Die neue Goethe-Uni-App kann mehr als ihre Vorgängerin und hat einen frischen Look bekommen. Gemeinsam mit den Studierenden will Chief Information Officer Ulrich Schielein sie nun noch besser machen.
Seit Januar gibt es die Goethe-Uni-App 2.0 zum Download für IOS und Android. Einmal heruntergeladen, lässt sich mit ihr der Uni-Alltag einfacher und komfortabler organisieren. Warum es sich unbedingt lohnt, Speicherplatz auf dem Smartphone für die neue App freizuhalten, und warum ein Hackathon nicht nur etwas für Programmierer*innen ist, erläutert Ulrich Schielein, CIO der Goethe-Universität, im Interview.
The introduction informs about Black literary imaginations of Europe that reverse or complicate the (neo-)colonialist European gaze at the "African Other". It reviews the state of research and provides an overview of the aims and sources of the special issue, whose individual contributions take into account both national specificities and transnational contexts. Sandra Folie and Gianna Zocco emphasise the important role of comparative literature for the field of African European studies (and vice-versa).
This contribution gathers eight interviews with international scholars of different generations and disciplines who study Black European literatures: Elisabeth Bekers, Jeannot Moukouri Ekobe, Polo B. Moji, Deborah Nyangulu, Jeannette Oholi, Anne Potjans, Nadjib Sadikou, and Dominic Thomas. The aim is to make literary research on Black Europe more visible to scholars in comparative literature and to contribute to a discussion on research perspectives, theories, and future challenges and needs.
