A taxonomic review of Attevidae (Lepidoptera: Yponomeutoidea) from China with descriptions of two new species and a revised identity of the Ailanthus webworm moth, Atteva fabriciella, from the Asian tropics.

Abstract

This review describes four species of Atteva (Lepidoptera: Yponomeutoidea: Attevidae) from China, including two new species: A. wallengreni n. sp. and A. yanguifella n. sp. The taxonomic identity of the Ailanthus webworm moth from South and Southeast Asia is revised with a designation of neotype for Phalaena (Tinea) fabriciella Swederus. Lectotypes of Atteva brucea Moore and A. niviguttella Walker are designated. Atteva brucea is synonymized with A. fabriciella. Synonymy of Atteva niviguttella and A. fabriciella is reconfirmed. The previous Chinese records of A. fabriciella were based on confusions with A. wallengreni n. sp. Confirmed specimens of A. fabriciella from China are reported. A pair of confused species, A. fabriciella and A. wallengreni n. sp., are distinguished by the number of white dots on the forewings and the genital features. Another confused pair, A. niveigutta and A. yanguifella n. sp., are compared by external and genital features. All type specimens of the described species are illustrated and compared with the conspecific specimens from various countries of the Asian tropics. Keys to all the species from China are provided.
