  1. Supplementary notes on the family Anthomyiidae of Japan (Diptera), VII

    Suwa, Masaaki
    Seven Japanese species of Anthomyiidae are dealt with. Four species are recorded as new to Japan: Adia alatavensis (Hennig, 1967), Chirosia strigilliformis (Deng et Li, 1986), Leucophora hangzhouensis Fan, 1988, and Pegomya hamata Wei, 1998. Pegomya prisca Michelsen, 2006, and Pegoplata fukushii Suwa, 1990, are synonymized with P. hamata and Pegoplata plicatura (Hsue, 1981) respectively. Adia cinerella (Fallen, 1825) is shown to have a slight but stable difference in the male terminalia between the European and Asian forms. Chirosia albitarsis (Zetterstedt, 1845) is newly recorded from Hokkaido.

  3. A first species of Tetramorium (Hymenoptera, Formicidae, Myrmicinae) with a polymorphic worker caste

    Yamane, Seiki; Jaitrong, Weeyawat
    A first Tetramorium ant with a polymorphic worker caste is described from Laos as T. polymorphum sp. nov. It may be most closely related to T. kheperra (Bolton), but is distinguished from the latter by the medially concave anterior margin of the clypeus and the lack of regular puncto-reticulation on the frontal area just behind the clypeus. The workers of T. polymorphum are roughly sorted into three size classes, In the minor and media workers most standing hairs on the dorsum of body are branched, while in the major worker and queen almost all the standing hairs are simple. Another...

  5. A new scale insect of the subtribe diaspidina from south India, with Notes on the subtribe (Sternorrtyncha: Coccoidea: Diaspididae)

    Takagi, Sadao
    Leptodiaspis nigra, n. gen. and n. sp., subtribe Diaspidina, is described on the basis of female specimens collected at the Periyar Tiger Reserve, Kerala, South India, on Cinnamomum malabatrum and C. zeylanicum, Lauraceae. It is peculia for a member of the subtribe in the female test slender and black and in the body of the full-grown adult female elongate fusiform, sclerotized throughout, and clearly partitioned into the prosoma, metathorax,and abdomen, but it is referable to the subtribe in the characters of the pygidium. The‘basic' character pattern composition, and distribution of the subtribe Diaspidina are discussed. Diaspis mihiriya, which was described...

  7. Revision of the genus Parachaitophorus Takahashi (Hemiptera: Aphididae: Drepanosiphinae), with descriptions of five morphs and biology of P. spiraeae (Takahashi, 1924) on Spiraea Cantoniensis (Rosaceae)

    Sugimoto, Shun'ichiro
    The aphid genus Parachaitophorus Takahashi, 1937 was reviewed. The morphological study and rearing experiment of P. spiraeae (Takahashi, 1924) and P. yamashitai Sorin, 1979 appearing on Spiraea cantoniensis (Rosacaeae) showed that the described morph of P. sikhotealinicus Pashtshenko, 1988 recorded from the Russian Far East corresponded to the fundatrix of P. spiraeae. Moreover, a field observation suggests that P. yamashitai should be treated as junior synonyms of P. spiraeae, and descrive five morphs and bilology of P. spiraeae appearing on S. cantoniensis.

  9. Two new species of the genus Eutrichosiphum Essig et Kuwana (Hemiptera: Aphididae: Greenideinae) on Lithocarpus edulis (Fagaceae) from Japan

    Sugimoto, Shun'ichiro
    Eutrichosiphum nigrisiphon sp. nov., and Eutrichosiphum apicifuscum sp. nov., are described and illustrated from Japan. These species were collected from the young leaves of Lithocarpus edulis (Fagaceae) planted as a roadside tree and had abbreviated holocyclic life cycles. The sexual morphs of the two species appeared from mid May into early June.

  11. Revision of the genus Osmylus (Neuroptera: Osmylidae: Osmylinae) of Japan

    Sekimoto, Shigeyuki; Yoshizawa, Kazunori
    Japanese species of Osmylus were recognized: O. (O.) pryeri McLachlan, 1875, O. (O.) hyalinatus McLachlan, 1875 and O. (O.) decoratus Nakahara, 1914. One species of the subgenus Plesiosmylus Makarkin, O. (P.) tessellatus McLachlan, 1875 was recognized. All Japanese species of Osmylus were redescribed and illustrated but O. kisoensis Iwara, 1928, which is known only from a larva to date, was not treated here. A key to the Japanese species of the genus is provided. In Appendix, two new combinations were proposed for two Chinese species, O. atomatus (Yang, 1988) and O. zheanus (Yang & Liu, 2001)(both originally assigned in the...
