珍珠菜属的新组合和新异名──兼论此属植物在中国和日本的地理替代现象

本文对过去一直认为是日本特有的两种珍珠菜属植物作了归并和组合：将Ｌｙｓｉｍａｃｈｉａ,ｔａｓｈｉｒｏｉＭａｋｉｎｏ归并作Ｌ．ｐａｔｕｎｇｅｎｓｉｓＨａｎｄ．－Ｍａｚｚ．的异名,将Ｌ．ｔａｎａｋａｅＭａｘｉｍ．降级作Ｌ．ｃｈｒｉｓｔｉｎａｅＨａｎｃｅ的亚种处理．对此间植物在中国和日本的地理替代现象作了讨论．     

Systematic study of the genus Compsilura Bouché in Southeast and East Asia with morphological and molecular data (Diptera,Tachinidae)

Compsilura concinnata (Meigen) is one of the most famous, most polyphagous and most widely distributed tachinid flies (Diptera, Tachinidae) in the world. This species is well known as a biocontrol agent of some injurious pests of cultural and wild plants and has been introduced from Europe to the United States to control mainly the gypsy moth. Recently we found three new species very closely resembling C. concinnata from Southeast and East Asia: C. lobata sp. nov. (Japan and Thailand), C. malayana sp. nov. (Malaysia) and C. pauciseta sp. nov. (Japan and Taiwan). Additionally, C. samoaensis Malloch is treated as a junior synonym of C. concinnata based on the examination of the type specimen. The genetic differences in the mitochondrial COI gene data are examined to assess the accuracy of species delimitation of Compsilura. The male postabdominal characters of these species are illustrated. The piercing female postabdomen of C. concinnata is illustrated and compared to those of other members belonging to the Blondelia group including Blondelia Robineau-Desvoidy, Celatoria Coquillett, Eucelatoria Townsend and Vibrissina Rondani.     

Revision of the Merodon aurifer group (Diptera: Syrphidae) with new synonyms of M. testaceus Sack, 1913

The hoverfly genus Merodon Meigen, 1803 (Diptera, Syrphidae), which comprises more than 200 species is distributed in the Palaearctic and Afrotropical Region, but one species, Merodon equestris, is a pest of flower bulbs and has been invasive into New Zealand and North America. In this work, the Merodon aurifer species group, a member of the M. avidus-nigritarsis lineage, is revised. The diagnostic characters of the M. aurifer species group, and the morphological differences between M. aurifer Loew, 1862 and M. nudicorpus sp. n. are explained and illustrated, as well as their distribution map. A detailed study of the type material resulted in three new synonyms: M. distinctus Palma, 1863 is a junior synonym of M. aurifer; M. manicatus (Sack, 1938) and M. testacoides Hurkmans, 1993 are junior synonyms of M. testaceus.Lectotypes are designated for two taxa M. aurifer and M. manicatus instead of the erroneously designated types for these species in Hurkmans (1993).     

Genus Microsternus Lewis (1887) from China,with description of a new genus Neosternus from Asia (Coleoptera,Erotylidae, Dacnini)

This work treats species of the genus Microsternus Lewis, 1887 from Asia and North America. A new genus is described: Neosternus (type species Microsternus higonius Lewis, 1887). A new species is described: Microsternus pengzhongi. A new synonym is provided: Microsternus tricolor taiwanicus Nakane (=Microsternus tricolor Lewis). Three species previously placed in Microsternus Lewis, 1887 are transferred to Neosternus resulting in the following three new combinations: Neosternus higonius (Lewis, 1887), Neosternus taiwanus (Chûjô, 1976), and Neosternus hisamatsui (Nakane, 1981).     

Lixus petiolicola n. sp. from Northeastern Turkey and Lixus furcatus Olivier: Comparative systematic and ecological study (Coleoptera: Curculionidae: Lixinae)

Lixus petiolicola n. sp. is described from Northeastern Turkey. Ecological data and morphological characters are presented in comparison with closely related species Lixus furcatus Olivier from the Palaearctic subgenus Callistolixus Reitter. Host plant of the new species is Prangos sp. (Apiaceae). Female lays eggs in the petiole where immature stages then develop; one generation is produced per year. Lectotypes of Lixus sitta Sahlberg 1823; L. parallelus Boheman 1842; L. eversmanni Hochhuth 1847; L. ferulaginis Apfelbeck 1899, and L. furcatus longicollis Petri 1905 are designated. A new synonymy is established: L. furcatus Olivier 1807 [=L. eversmanni Hochhuth 1847, n. syn.]. The name of L. recurvus Olivier 1807 is resurrected, excluded from synonyms of L. furcatus and attributed to the L. iridis group.     

红果黄檀一新异名

通过对红果黄檀(Dalbergia tsoi Merr. et Chun)和白沙黄檀(D. peishaensis Chun et T. Chen)的标本研究及野外观察,确认两者为同种植物,故将白沙黄檀处理为红果黄檀的异名。     

野丁香属植物的一个新异名

通过对野生植物及馆藏标本的观察比较,确认伞花野丁香(Leptodermis umbellata Batalin)与文水野丁香(L.diffusa Batalin)为同种植物,故予以归并。     

Ecology,development and pathogenicity of Buddenbrockia plumatellae Schröder, 1910 (Myxozoa,Malacosporea) (syn. Tetracapsula bryozoides) and establishment of Tetracapsuloides n. gen. for Tetracapsula bryosalmonae

Buddenbrockia plumatellae, an enigmatic worm-like myxozoan, was observed as continuously writhing free and attached 'worms' and as free mature spores in the coelom of the freshwater bryozoans Plumatella fungosa, Hyalinella punctata, and Fredericella sp. 'Worm' numbers could double every three days. 'Worms' and spores could be expelled from colonies by external pressure. Some mature 'worms' exited actively, entraining release of free spores, and gradually ceased movement outside the host. Bryozoans sealed off infected regions of the colony. Infected colonies grew slowly, produced no statoblasts, and eventually regressed and died. Transmission was not achieved and prevalence was low. Electron microscopy of 'worms' revealed a single layer of mural cells on a fibrous basal lamina overlying four longitudinal muscle blocks and an inner sheet of two types of proliferating cells, an organization indicative of the bilaterian ancestry of the Myxozoa. Primary type A cells were attached directly by striated tubules to mural cells at positions between muscle blocks. Secondary type A cells had a secretory function. Type B cells underwent meiosis and subsequently developed to typical malacosporean myxozoan spores filling the internal cavity of the 'worms'. External tubes were formed during capsulogenesis in 'worms' from Fredericella sp. Tetracapsula bryozoides is synonymised with Buddenbrockia plumatellae and a new genus is proposed for Tetracapsula bryosalmonae.
