Tamarixia aguacatensis Yefremova, sp. n. (Hymenoptera: Eulophidae: Tetrastichinae) is described from Mexico as a parasitoid of the avocado psyllid, Trioza aguacate Hollis & Martin (Hemiptera: Triozidae). Trioza aguacate is a serious pest of avocado, Persea americana Miller. A key to the species of Tamarixia Mercet in Mexico is given.

基于18S基因序列的姬小蜂分子系统发育

本文基于18S rDNA部分序列,用MP和Baysian方法研究了姬小蜂科的系统发育,对姬小蜂科的单系性及其与其它小蜂科间的关系进行了讨论。姬小蜂亚科、灿姬小蜂亚科和啮姬小蜂亚科形成三个独立的支系,研究结果支持它们各自的单系性,但本结果没有明确姬小蜂科的单系性。研究结果同时还支持瑟姬小蜂族、扁股姬小蜂族和狭面姬小蜂族三个族的地位,但不支持姬小蜂族的地位。姬小蜂科的单系性及其与其它小蜂间的关系还需更多的形态学数据和更多的基因序列来进一步研究[动物学报52 (2) : 288 -301 , 2006]。     

Calosota Curtis (Hymenoptera, Chalcidoidea, Eupelmidae) - review of the New World and European fauna including revision of species from the West Indies and Central and North America

Two of three species previously classified in Calosota Curtis (Hymenoptera: Eupelmidae) from the Neotropical region are transferred to Eupelminae. Calosota eneubulus (Walker) from Galapagos Islands is transferred to Eupelmus Dalman as Eupelmus (Eupelmus) eneubulus (Walker), comb. n., and Calosota silvai (Brèthes) from Chile is transferred to Brasema Cameron as Brasema silvai comb. n. Calosota cecidobius (Kieffer) from Argentina is retained in Calosota, with reservation, as an unrecognized species. The species of Calosota from the New World excluding South America are revised. Eleven species are recognized, including the seven newly described species Calosota albipalpus sp. n. (Costa Rica, Mexico, USA, Venezuela), Calosota bicolorata sp. n. (USA), Calosota elongata sp. n. (USA), Calosota longivena sp. n. (USA), Calosota panamaensis sp. n. (Panama), Calosota setosa sp. n. (Bahamas, Dominican Republic, USA), and Calosota speculifrons sp. n. (Costa Rica, USA). The 11 regional species and the Palaearctic species Calosota vernalis Curtis are keyed and illustrated. Calosota vernalis is not known to occur in the New World but is included in the key and diagnosed because it has been intercepted in quarantine in Canada. Calosota pseudotsugae Burks is placed in synonymy under Calosota acron (Walker), syn. n.,and Calosota kentra Burks, Calosota montana Burks and Calosota septentrionalis Hedqvist are placed in synonymy under Calosota aestivalis Curtis syn. n. Calosota modesta Bolívar y Pieltain is removed from synonymy under Calosota viridis Masi, stat. rev., and Calosota viridis, Calosota matritensis Bolívar y Pieltain, and Calosota coerulea Nikol’skaya are placed in synonymy under Calosota metallica (Gahan), syn. n. Calosota grylli Erdös is confirmed as a separate species from Calosota metallica based on features of both sexes. It is suggested that Calosota ariasi Bolívar y Pieltain may be a synonym of Calosota aestivalis, Calosota bolivari Askew may be a synonym of Calosota agrili Nikol’skaya, Calosota dusmeti Bolívar y Pieltain may be a synonym of Calosota violascens Masi, and Calosota lixobia Erdös likely is not a junior synonym of Calosota obscura Ruschka, but formal nomenclatural changes are not proposed prior to a comprehensive Palaearctic revision. Previous interpretation of the mesoscutum in Calosota and Balcha Walker is also modified to include the presence of anteroadmedian lines in addition to notauli and parapsidal lines.

A taxonomic study of Chinese species of the insidiosus group of Metaphycus (Hymenoptera,Encyrtidae)

In this paper, twelve insidiosus-group species of the genus Metaphycus Mercet from China are reviewed. Five species, M. corniae sp. n., M. cylindricus sp. n., M. deltoideus sp. n., M. transversus sp. n. and M. yaanensis sp. n., are described as new to science. A key to the females of these species is given to facilitate species recognition. Photomicrographs are provided to illustrate morphological characters of these species. All specimens, unless otherwise specified, are deposited in the National Zoological Museum of China, Institute of Zoology, Chinese Academy of Sciences, Beijing.
