RESUMEN
Four species of Anastatus Motschulsky (Hymenoptera, Eupelmidae, Eupelminae) are newly reported as egg parasitoids of the Japanese giant silkworm, Caligula japonica Moore and, as an alternate laboratory host, the Chinese oak silk moth, Antheraea pernyi (Guérin-Méneville) (Lepidoptera, Saturniidae) in China. The four species, A. fulloi Sheng & Wang, 1997, A. gansuensis Chen & Zang, sp. nov., A. japonicus Ashmead, 1904, and A. meilingensis Sheng, 1998, were reared initially from eggs of C. japonica collected in Gansu, Jilin and Liaoning provinces and subsequently cultured in the laboratory on eggs of A. pernyi. An illustrated key to differentiate females of the four species, and males of some of the species is provided. Key features are illustrated, both sexes of the new species are described, and diagnoses of females of the other species are given.
RESUMEN
Octodonta nipae (Maulik, 1921), a hispid that damages several species of palm trees, was introduced accidently into China in 2001. The egg, larva, prepupa and pupa of O. nipae are illustrated and described in detail and compared with another invasive species, Brontispa longissima (Gestro, 1885); the scanning electron micrographs of the head capsule, antenna, maxilla, labium and lateral scoli are provided, as well as photos of body of all larval instars and pupa. It is the second description of immature stages in the genus Octodonta Chapuis.
