ERMOLAEV Abstract KUMATA, T., KUROKO, H. and ERMoLAEv, V.P. 1988. japanese species of the Acrocercops· group (Lepidoptera: Gracillariidae), Part II. Ins. matsum. n. s. 40, 133 pp., 1 table, 59 figs. (33 text·figs., 26 pis.). In Part II 25 species of Acrocercops·group occurring in japan are dealt with and are arranged in 9 genera, that is, 5 in Gibbovalva (gen. nov.), 2 in Melanocercops (gen. nov.), 2 in Phodoryctis (gen. nov.), 2 in Borboryctis (gen. nov.), 2 in Leucospilapteryx, 1 in Chrysocercops (gen. nov.), 4 in Telamoptilia (gen. nov.), 6 in Spulerina and 1 in Dendrorycter. Nine new species are described: Gibbovalva kobusi (host: Magnolia kobus), G. magnoliae (host: Magnolia ovobata), Phodoryctis stephaniae (host: Stephania), Borboryctis euryae (host: Eurya) , Chrysocercops castanopsidis (host: Castanopsis & Pasania), Telamoptilia tiliae (host: Tilia), Spulerina castaneae (host: Castanea & Quercus), S. virgulata (host: Quercus) and S. parthenocissi (host: Parthenocissus). Of them, Spuler· ina castaneae and S. virgulata are stem·miners and the rest are leaf· miners. Two new associations of synonyms are proposed: Gracilaria (1) ordinatella Meyrick, 1880 = Gibbovalva quadrifasciata (Stainton, 1863), and Spulerina lespedeziJoliella Kuroko, 1982 = Spulerina dissotoma (Meyrick, 1931). In connection with this study, Acrocercops elaphopa Meyrick, 1914 (occurring in India) is transferred to Melanocercops, and Acrocercops malicola Meyrick, 1921 (in India) to Spulerina. All the genera, whether new or not, are described in detail, and every known species is given the original description followed by an additional description. Genitalia are illustrated for both sexes, and wing patterns are shown by photographs. The wing venation and larval body chaetotaxy are also illustrated for some species. Further the genitalia and wing venation of the type· species of the genera Spulerina, Sauterina, Amblyptila and Lamprolectica are illustrated for comparison. Authors' addresses. T.

These species are classified in 9 genera, that is, 5 in Gibbovalva (gen. nov.), 2 in Melanocercops (gen. nov.), 2 in Phodoryctis (gen. nov.), 2 in Borboryctis (gen. nov.), 2 in Leucospilapteryx Spuler, 1 in Chrysocercops (gen. nov.), 4 in Telamoptilia (gen. nov.), 6 in Spulerina Vari and 1 in Dendrorycter Kumata. CORRIGENDA TO PART I "Decheng", the author of Cryptolectica ensiformis (p. 17) and Acrocercops unis­ triata (p. 56), should be emended to "Yuan". On this occasion we apologize to Mr. Yuan Decheng for our mistake. IX. GENUS GIBBOVALVA KUMATA ET KUROKO NOV. Type-species: Gracilaria (!) quadrifasciata Stain ton, 1863.
