A revision of the tribe Plectrothripini of fungus-feeding Thysanoptera (Phlaeothripidae: Phlaeothripinae)

Abstract The tribe Plectrothripini is redefined with examination of its systematic relationships. Keys are provided to the ten genera and forty-seven species in this tribe; one genus and eighteen species are newly described; one genus and two species are newly synonymized; two genera, Chiridothrips and Eurytrichothrips , are here removed from this tribe. The species of the tribe occur throughout the tropical and subtropical regions of the world; seventeen species are recorded from the Oriental Region, seventeen species from the Neotropical Region, ten species from the Afrotropical Region, two from Australia and one from the Pacific. They seem to be fungus-feeders, being found mainly under the bark of trees or on dead branches.

Physical mapping of rDNA genes in the ground beetle Carabus and related genera (Carabidae: Coleoptera)

The major ribosomal DNA (rDNA) loci were localized on meiotic and mitotic chromosomes and in interphase nuclei of 18 ground-beetle species belonging to three tribes of the supertribe Carabitae by fluorescence in situ hybridization (FISH), using a PCR-amplified 18S rDNA as a probe. Meiotic observations indicate that the 18S rDNA sequences are located on the largest autosomal bivalent in 12 species of Carabus , two species of Calosoma (both genera belonging to the tribe Carabini), and three sibling species of Ceroglossus chilensis (tribe Ceroglossini). The data suggest the occurrence of a conservative pattern in these three genera despite the chromosomal rearrangements that have led to karyotypes with higher chromosome numbers in Ceroglossus . A different result is found in Cychrus caraboides (tribe Cychrini), where ribosomal cistrons are located in two medium-sized autosomal pairs. Further species of Cychrini should be studied for corroborating the occurrence of molecular and karyotypical apomorphies in Cychrus with regard to the genera Carabus, Calosoma and Ceroglossus .     

Molecular systematics and evolution in an African cycad-weevil interaction: Amorphocerini (Coleoptera: Curculionidae: Molytinae) weevils on Encephalartos

Weevils in the tribe Amorphocerini have been implicated in pollination of Encephalartos species in southern Africa. The services they render these plants and the unique attributes of the cycad-weevil interaction make them important from both conservation and evolutionary standpoints. Oberprieler [Oberprieler, R.G., 1996. Systematics and evolution of the tribe Amorphocerini, with a review of the cycad weevils of the world. Ph.D. dissertation, University of the Free State, Bloemfontein, South Africa], using morphological characters, proposed a tentative hypothesis of relationships among the Amorphocerini which is tested here using DNA sequence data. Sequences from one mitochondrial and three nuclear genes were used to infer phylogenetic relationships, levels of sequence divergence, evolution of host associations, and patterns of speciation in this tribe. The results are reasonably consistent with the morphological hypothesis of relationships and species concepts, though important differences are observed, particularly in relationships among a Porthetes hispidus Boheman species group, which is indicated to have experienced recent divergences. In general, low levels of sequence divergence among species within two of the three genera indicate a recent radiation of this tribe onto African cycads, thus while cycad-insect interactions have often been considered ancient this may not be the case for some extant interactions. A complex pattern of host shifts onto both closely related and more distantly related hosts is suggested.

THE SISTER GROUP OF THE PALEOTROPICAL TRIBE ARGOSTEMMATEAE: A REDEFINED NEOTROPICAL TRIBE HAMELIEAE (RUBIACEAE, RUBIOIDEAE)

Abstract— The sister group of the monophyletic tribe Argostemmateae, including Argostemma and Neurocalyx , is not the tribe Hedyotideae, or a part of it, as earlier assumed, but the monophyletic tribe Hamelieae, here redefined. It comprises the genera Hamelia, Hoffmannia (here including Xerococcus), Deppea (here including Schenckia), Pinarophyllon , and Omiltemia . The two tribes Argostemmateae and Hamelieae are a monophyletic group characterized by seven synapomorphies. A cladogram is presented showing the relationships of the seven genera based on 31 characters. One group of characters, the aestivation of the corolla, is shown to be much more complicated than hitherto assumed. In the Hamelieae the aestivation can be imbricate (to the right or to the left and quincuncial or not), contorted (to the right), alternative, or even valvate. The Argostemmateae occur in the Old World Tropics, and their distribution supports the hypothesis that at least parts of southeast Asia are a part of Gondwanaland. The vicariant pattern within the Argostemmateae indicates that the large area from west Africa through northern India to southeast Asia is vicariant to Ceylon and southern India. The distribution of the Old World tribe Argostemmateae is vicariant to the essentially Central American tribe Hamelieae.     

The higher classification of the ant subfamily Leptanillinae (Hymenoptera: Formicidae)

Abstract. Until now the ant subfamily Leptanillinae has been closely linked with the army ant subfamilies Dorylinae and Ecitoninae, but on relatively tenuous evidence. The current phylogenetic study strongly indicates that this view is incorrect and that the leptanillines really constitute the sister-group of subfamily Ponerinae, and are at a consider- ably greater taxonomic distance from the Army Ant subfamilies. Three tribes are now recognized within the Leptanillinae (Leptanillini; Anomalornyrmini, new tribe; and Apomyrmini, transferred here from Ponerinae: Arnblyoponini), containing a total of eight genera with fewer than fifty species in all. The subfamily and its component tribes are diagnosed and discussed here, and a key to genera provided. New taxa described include Anomalomyrma Taylor gen.n., type-species A. taylori Bolton sp.n. and Protanilla Taylor gen.n., type-species P. rafflesi Taylor sp.n.

Taxonomic significance of pollen types in the Guyana Highland-centred composite genera of Mutisioideae (Asteraceae)

The Guyana Highland-centred genera, or Stenopadus group, are a complex of species that belong to the tribes Mutisieae and Stifftieae of Asteraceae. The pollen morphologies of 29 species, from 12 of 13 genera of this complex, are described and illustrated using light and scanning electron microscopy. The exine sculpture and structure are highly significant. Four exine types, previously characterized, were distinguished: Gongylolepis , Wunderlichia , Mutisia , and Stenopadus . The characterization of the Stenopadus exine type is enlarged here. These exine types led to the recognition of four well-defined pollen types, whereas the spine length and exine thickness characterized six subtypes. Pollen types circumscribe genera or groups of genera, and some subtypes distinguish species. The pollen morphology within the complex is discussed in relation to the rest of Mutisioideae and other palynologically allied tribes of Cichorioideae. There is little correlation between pollen types and tribes; only the Stenopadus exine type is exclusive to the Stifftieae tribe. The remaining types are shared by the two tribes of the complex. Pollen morphology supports the hypothesis that this group of genera is close to the Gochnatia complex and the Cardueae tribe.  © 2008 The Linnean Society of London, Botanical Journal of the Linnean Society , 2008, 156 , 327–340.     

新疆蚜虫的物种多样性研究

从分类阶元、寄主植物和寄生部位等角度系统研究了新疆蚜虫类昆虫的物种多样性,共发现蚜虫5科57属183种,寄主植物55科192属.无论在属级水平还是在种级水平,蚜科均有绝对优势,分别占新疆所有属数和种数的64.90%和65.60%.结果表明,新疆蚜虫的地理分布具有明显的纬度和经度梯度性,这与天山山脉在新疆的地理位置和走向是紧密相关的.另外,受植被分布和人类活动的影响,新疆蚜虫还具有明显的岛屿状分布特征.
