N. grandis Xu, Olmi et He, sp. nov. from China (Guangdong) is described and illustrated. The status of N. malayanus (Olmi) is resurrected. Dryinidae are parasitoids of Hemiptera Auchenorrhyncha (Guglielmino & Olmi 1997, 2006, 2007). The genus Neodryinus Perkins 1905 is distributed in all zoogeographical regions (Olmi 1984, 1999) and numbers forty-four species, amongwhich sixteen were described from the Oriental region (Enderlein 1907; Fouts 1922; Olmi 1984, 1991, 1995, 1998, 2008; Richards 1953; Roepke 1916; Xu & He 1996, 1997; Xu et al. 2003). Ponomarenko (1981) recorded the Australian Neodryinus nelsoni Perkins1905 in Sri Lanka. Olmi (1984) examined the specimen seen by Ponomarenko (deposited in USNM) and concluded that it was not a nelsoni, but a different species not recognizable, because its head was missing. The species of Neodryinus are known as parasitesof Flatidae, Nogodinidae and Ricaniidae (Guglielmino & Olmi 1997, 2006).

The analysis of new sets of characters on the genitalcapsule, flagellum articulating to temones and basal piece extension of the male genitalia were found to be helpful in delimitating the three Amphicoma species in addition to the previously established diagnostic paramere characters. Two other undocumented character states on median lobe of the male genitalia are also discussed.

Because of insufficient labelling, the type status of some specimens had to beclarified and four lectotypes were designated. Syrphophilus stibarus Momoi, 1973 is conspecific with Syrphophilus dilleria-tor Aubert, 1976, syn. nov., and Syrphoctonus lipothrix (Momoi, 1973) is a junior synonym of Syrphoctonus haemorrhoidalis (Szepligeti, 1898), syn. nov. Diplazon multicolor (Gravenhorst, 1829) is removed from synonymy with Diplazon annulatus (Gravenhorst, 1829), stat. rev. A new species is described, Sussaba mongolica sp. nov., and the male of Syrphoctonus venustus (Dasch, 1964) isre-described to account for the material from Mongolia. The ultrastructure of the tyloids of three species is illustrated by scanning electron micrographs to demonstrate their large variability in the subfamily. Seven species are recorded for the first time from Mongolia, four of which are recorded for the first time from the Eastern Palaearctic. These data on the Mongolian diplazontines provide further evidence for an unusually large proportion of species of this subfamily with a multire-gional distribution.
查看更多>>摘要：Costalimada brasiliensis, gen. and sp. nov. is described from Lafoensia pacari (Lythraceae) in Minas Gerais, Brazil. Its position within the Aleurodicinae is discussed, and an amendment to a previously published key to worldwide genera of Aleurodicinae is presented. The definitions of many of the New World genera of Aleurodicinae have been unsatisfactory for many decades (Martin, 2008a). Some early attempts to provide keys to whitefly genera of both subfamilies (e.g. Bondar, 1923; Sampson, 1943; Sampson & Drews, 1941, 1956) tended to provide couplets of unrealistic brevity, and also revealed more taxonomic problems than were solved. Over the past seven years the present author has studied examples of puparia of all nominal aleurodicine genera from the Neotropical Region, along with a large proportion of the described species. In 2004 a key to the puparia of New World aleurodicine genera was presented, based on revised generic diagnoses suggested by a study of whiteflies in Belize (Martin, 2004). This study led to the description of Kaieteurodicus, a new genus of neotropical aleurodicine whitefly from Guyana and Panama, accommodating two species (Martin, 2008a). This was followed by a revision of the type genus of the Aleurodicinae, Aleurodicus Douglas, in which an identification key to all genera of Aleurodicinae was presented, including those native to the Old World (Martin, 2008b).
查看更多>>摘要：This paper reviews species of the genus Euconocephalus Karny from China, provides a key to species from China, and describes a new species, namely E. longissimus Wang & Shi sp. nov.. This new species differs from known species in the genus in the following: body comparatively large; fastigium verticis relatively long, ventral margin about 3 times as longitudinal diameter of eyes; Cu2 vein slender and long, with about 105 teeth (E. nasutus and E. pallidus with about 70 teeth); titillators symmetricalL-shaped, apical parts widened, and basal parts outcurved (E. nasutus X-shaped, flat; E. pallidus apical parts closed, and basal portions outcurved). The type specimens are deposited in the Museum of Hebei University and Faculty of Conservation Biology,Southwest Forestry University.
