The American Brachinepticula gen. nov. and Manoneura Davis (Nepticulidae): a new generic concept based on a reinforced cathrema in the phallus

Abstract

We describe one new genus (Brachinepticula Stonis & Diškus, gen. nov.) with two new species (B. plurilobata Diškus & Stonis, sp. nov., B. elongata Remeikis & Stonis, sp. nov.), and one species with uncertain taxonomic position (Johanssoniella bina Remeikis & Stonis, sp. nov.). We also provide diagnostic characters and an updated annotated catalogue of the following related genera: newly restored Johanssoniella Koçak, Brachinepticula gen. nov., Enteucha Meyrick (s. str.) and Manoneura Davis. In the Annotated Catalogue, we provide five new combinations and new data on morphology, biology, and distribution of some species, including the first photographic documentation of Manoneura basidactyla Davis discovered in the Amazon rainforest, results of re-examination of the male genitalia of the European Johanssonia acetosae (Stt.), also the first documentation of the male genitalia, host plant and leaf mines of the little known Johanssoniella diplocosma (Meyrick) from the Himalayas. All new taxa treated in the paper are illustrated with drawings and (or) photographs of the adults and genitalia; photographs of the leaf mines of Brachinepticula plurilobata Diškus & Stonis, sp. nov. and Johanssoniella diplocosma (Meyrick) are also provided.
