ZOOSYSTEMATICA ROSSICA, 21(1): 169–172 25 JULY 2012 Paralypusa, a new genus of the family Lypusidae (Lepidoptera: Gelechioidea) from China Paralypusa – новый род семейства Lypusidae (Lepidoptera: Gelechioidea) из Китая A.L. LVOVSKY А.Л. ЛЬВОВСКИЙ A.L. Lvovsky, Zoological Institute, Russian Academy of Sciences, 1 Universitetskaya Emb., St Petersburg 199034, Russia. E-mail: [email protected] A new eastern-palaearctic monotypic genus of the gelechioid moths, Paralypusa gen. nov., is established for the Chinese species Paralypusa chinensis (Lvovsky, 2010), comb. nov. This genus is considered closely related to Lypusa Zeller, 1852 on the base of several synapomor- phies. However Paralypusa also shares some features with the genera Pseudatemelia Rebel, 1910 and Amphisbatis Zeller, 1870. Its transitional state confirms the belonging of all the afore- mentioned genera to one family and synonymy of the Lypusidae Herrich-Schäffer, 1857 and Amphisbatidae Spuler, 1910 (Nieukerken et al., 2011). Описан новый восточнопалеарктический монотипический род гелехиоидных чешуекры- лых Paralypusa gen. nov., включающий китайский вид Paralypusa chinensis (Lvovsky, 2010), comb. nov. Этот род сближается с родом Lypusa Zeller, 1852 на основании ряда синапоморфий. Тем не менее, Paralypusa также имеет признаки, общие с Pseudatemelia Rebel, 1910 и Amphisbatis Zeller, 1870. Его промежуточное положение подтверждает принадлежность всех вышеупомянутых родов к одному семейству и синонимию Lypusi- dae Herrich-Schäffer, 1857 and Amphisbatidae Spuler, 1910 (Nieukerken et al., 2011).
