查看更多>>摘要:Seven species of Timia Wiedemann, 1824, differing from the rest of members of this genus by yellow body are reviewed. All of them, including two new species are described and figured. Timia (Timia) zaitzevi Galinskaya sp. nov. from Kazakhstan is similar to T. (T.) testacea Portschinsky, 1892, differing by the presence of a short postero-dorsal extension of the cell bcu (not longer than the width of cell bcu), and by the presence of a silvery-white microtrichosity on mesonotum, with rows of confluentshining spots around the base of setae. Timia (Empyelocera) flaveola Galinskaya sp. nov. from Turkmenistan is similar to T. (E.) orientalis Zaitzev, 1982, but differs by the presence of a silvery-white microtrichosity on mesqnotum, without confluent shining spots around bases of setae. Lectotypes are designated for Timia (Timia) testacea Portschinsky, 1892 and Timia (Empyelocera) canaliculata Becker, 1906. A key to eight species (including T. (E.) ber-landi Seguy, 1953), descriptions and illustrations are provided.
查看更多>>摘要:Species of the small reduviid subfamily Physoderinae from China are reviewed and two species are recognized in the genus Physoderes Westwood. Physoderes esakii is formally described for Esaki's (1931) Epirodera latithorax nom. nud. based on his uniquespecimen kept in the Entomological Laboratory of Kyushu University. Physoderes impexa Distant, 1903 is recorded for the first time from China with a detailed redescription. A key for these two species is also given.
查看更多>>摘要:Sitobion (Metobion) graminearum (Mordvilko, 1919) is redescribed based on type material, earlier published data and new material. A lectotype is designated and data provided on the distribution and biology of the species. Sitobion (Metobion) graminearum (Mordvilko, 1919) was described as Acyrthosiphon (Metopolophium) graminearum from a few oviparous females and males taken near Petrograd (now St. Petersburg), Russia, at Razdel'naya (now Lisiy Nos) railway station. The aphids were collected by Mordvilko from leaves of an unidentified grass on 23.ix. 1913. Hille Ris Lambers (1947) recognised Metopolophium as a full genus, and Metopolophium graminearum was subsequently recorded from the Eastern Alps by Borner (1952), and from Hohe Tauern by Borner & Franz (1961).
查看更多>>摘要:The egg of Paederidus ruficollis (Fabricius, 1781) and larvae of that and P. rubrothoracicus carpathicola Scheerpeltz, 1957 are described and illustrated. This is the first thorough description of immature stages for the genus Paederidus Mulsant & Rey(1878). The immature stages were obtained by rearing adults. Morphological differences between instars of the same species and also between the studied species are found in the detailed structure of the antenna, nasale, maxillary palp, labial palp, tarsungulus and urogomphus; chaetotaxy of pronotum, profemur and protibia; proportions of same body parts; microstructure of urogomphus and body colour. Comparative characters of larvae of two subtribes Paederina and Stilicina are presented.
查看更多>>摘要:Pentatomomorpha is one of the most diversified infraorders of the true bugs (Insecta: Hemiptera: Heteroptera). The phylogenetic relationships among superfamilies within this infraorder are still in dispute. In this study, 31 species representing 26 pentatomomorphan and four cimicomorphan putative families were chosen, and six Hox gene fragments with as many as 4 kilobases for each representative were analyzed to reconstruct the phylogeny of the Pentatomomorpha. The (Hanieotic) Hox gene family is a group of nuclear genes, which is considered to determine animal segmentation. The combined nucleotide and amino acid sequences were used separately as two data matrices, and analyzed by employing maximum likelihood and Bayesian methods. Results strongly support the monophyly of Trichophora and the superfamilies Pentatomoidea, Lygaeoidea, Coreoidea, and Pyrrhocoroidea. The relationship of (Aradoidea + (Pentatomoidea + (Lygaeoidea + (Coreoidea + Pyrrhocoroidea)))) was mostly congruent with previous resultsbased on the morphological data. Our results suggested that the Hox genes could be used as novel molecular markers for phylogenetic research on the Pentatomomorpha and other insects.
