Mikrolepidopteren gehörten seit der ersten Hälfte des 19. Jahrhunderts zum Gegenstand entomologischer Forschung in Eberswalde. Zentren der Forschung waren zunächst die Forstlichen Lehranstalten und Institute, später auch das Deutsche Entomologische Institut. Außerdem war die Eberswalder Gegend stets Anziehungspunkt für viele Mikrolepidopteren-Spezialisten, die nicht an einschlägigen wissenschaftlichen Instituten arbeiteten. In der vorgelegten Arbeit werden die Forschungsergebnisse aus der Vergangenheit regionalfaunistisch ausgewertet und durch Ergebnisse aktueller faunistischer Forschungen zu einem Verzeichnis der Microlepidoptera der Diluviallandschaften um Eberswalde ergänzt. Das Verzeichnis umfasst mit 863 Arten aus 47 Familien 57 % der im Land Brandenburg nachgewiesenen Mikrolepidopteren-Arten, darunter ein Neufund für Deutschland: Clepsis coriacanus; 13 Neufunde für das Land Brandenburg: Coleophora adjectella, Colephora sylvaticella, Coleophora ramosella, Mompha terminella, Monochroa arundinetella, Bryotropha umbrosella, Anarsia innoxiella, Telephila schmidtiellus, Cydia gemmiferana, Acrobasis legatea, Pammene herrichiana, Pammene ignorata, Schreckensteinia festaliella; und 45 Wiederfunde im Land Brandenburg. Die Autoren konnten 332 Arten erstmals im Eberswalder Raum nachweisen. Für 531 Arten wurden ältere/historische Nachweise ausgewertet. Das Vorkommen von 408 dieser Arten konnte bestätigt werden. Die Funddaten sind tabellarisch dargestellt und sowohl Naturräumen des Gebietes als auch Messtischblättern zugeordnet., Beiträge zur Entomologie = Contributions to Entomology, Bd. 70 Nr. 1 (2020)

The published records ofEriocraniachrysolepidellaZeller, 1851,Incurvariakoerneriella(Zeller, 1839) andLamproniaaeneella(Heinemann, 1870) from Chuvash and Karelia Republics in Russia are based on misidentified specimens. This finding, along with earlier reports on the widespread occurrence of errors, even in the most authoritative works, calls for a critical approach to published data in order to stop spreading and citing false information across future publications.

Pheromone receptors (PRs) are essential in moths to detect sex pheromones for mate finding. However, it remains unknown from which ancestral proteins these specialized receptors arose. The oldest lineages of moths, so-called non-ditrysian moths, use short-chain pheromone components, secondary alcohols, or ketones, so called Type 0 pheromones that are similar to many common plant volatiles. It is, therefore, possible that receptors for these ancestral pheromones evolved from receptors detecting plant volatiles. Hence, we identified the odorant receptors (ORs) from a non-ditrysian moth, Eriocrania semipurpurella (Eriocraniidae, Lepidoptera), and performed functional characterization of ORs using HEK293 cells. We report the first receptors that respond to Type 0 pheromone compounds; EsemOR3 displayed highest sensitivity toward (2S, 6Z)-6-nonen-2-ol, whereas EsemOR5 was most sensitive to the behavioral antagonist (Z)-6-nonen-2-one. These receptors also respond to plant volatiles of similar chemical structures, but with lower sensitivity. Phylogenetically, EsemOR3 and EsemOR5 group with a plant volatile-responding receptor from the tortricid moth Epiphyas postvittana (EposOR3), which together reside outside the previously defined lepidopteran PR clade that contains the PRs from more derived lepidopteran families. In addition, one receptor (EsemOR1) that falls at the base of the lepidopteran PR clade, responded specifically to β-caryophyllene and not to any other additional plant or pheromone compounds. Our results suggest that PRs for Type 0 pheromones have evolved from ORs that detect structurally-related plant volatiles. They are unrelated to PRs detecting pheromones in more derived Lepidoptera, which, in turn, also independently may have evolved a novel function from ORs detecting plant volatiles.

A new species of Eulophinae,Pnigalio eriocraniaeLi & Yang,sp. n., is described and illustrated. This new species is a larval ectoparasitoid ofEriocrania semipurpurella alpinaXu (Lepidoptera, Eriocraniidae), a leaf miner in birch trees,Betulaspp. (Betulaceae), in Qinghai Province, northwest China. The biology of the new species and a key to the known species from China are provided.
