Pameridea (Hemiptera: Miridae): Predaceous bugs specific to the highly viscid plant genus Roridula

Abstract. The South African genus Pameridea and its two species are redescribed. The tribe Pamerideini, founded for this genus only, is removed from synonymy with Mirini (subfamily Mirinae) and transferred to Dicyphini (subfamily Bryocorinae), falling as a synonym of the subtribe Dicyphina. The bugs live only on intensely viscid small shrubs of the genus Roridula. This plant genus is the only member of its family but the bug genus is closely related to two widespread tropical dicyphine genera.     

弹尾纲刺齿虫兆属的自然分布扩散及地理起源

基于刺齿虫兆属的自然地理分布特征和调查资料,讨论了弹尾纲刺齿虫兆属的自然分布、扩散和地理起源。结果显示,全球已经描述的57种刺齿虫兆,不仅主要分布于亚洲(54种),而且中国的物种数量最多(32种),土著种数量亦最多(23种)。亚洲之外美国大陆的3个州有2种(全为广布种);夏威夷有6种(包括3个广布种)。作者初步提出了刺齿虫兆属起源和扩散的假设。     

New species and records of Charisius Champion from Mexico and Central America (Coleoptera,Tenebrionidae, Alleculinae)

The species of the genus Charisius Champion, from Mexico and Central America are reviewed. The flightless genus Narses Champion, with one included species, N. subalatus Champion, is placed in synonymy with the genus Charisius. Four new species are described and illustrated, C. granulatus and C. punctatus (from Guatemala) and C. apterus and C. howdenorum (from Mexico). Charisius subalatus (Champion) is redescribed and illustrated. The species C. interstitialis Champion is placed in synonymy with C. zunilensis Champion. The genus is redescribed to include the four new species and N. subalatus. New distributional records are presented for all other species of the genus and a revised key is presented for identification of all the species of the genus.     

The Pupa and Larva of Propsilocerus taihuensis (Wen,Zhou & Rong) (Diptera: Chironomidae), with Complete Keys to all Immatures of the Genus Propsilocerus

The pupa and larva of Propsilocerus taihuensis (Wen, Zhou & Rong, 1994) are described for the first time. Both are close to P. akamusi (Tokunaga). The phylogenetic argumentation of the genus outlined in Sæther and Wang (1996) is confirmed. Revised keys to larvae and pupae of the genus are given. The main morphological characters of the different species of the genus are compared in tables.     

Alavesia Waters and Arillo–a Cretaceous‐era genus discovered extant on the Brandberg Massif,Namibia (Diptera: Atelestidae)

Two new extant species of the fossil genus Alavesia Waters & Arillo (A. brandbergensis sp.n. and A. daura sp.n. ) are described from the Brandberg Massif, Namibia. The genus is reassigned to the family Atelestidae (subfamily Atelestinae) on the basis of male terminalia (elongate gonocoxal apodemes, ventral apodemes, subapical surstylus), female terminalia (absence of tergum 10) and a three‐articled stylus. This is the first record of Atelestidae from the Afrotropical Region. A genus‐level phylogeny of the Atelestidae is resolved, in which Alavesia is the sister genus to the remaining genera of the Atelestinae. The biogeographic history of the genus is briefly discussed, as is the significance of this and other relict Diptera on the Brandberg.     

FURTHER STUDIES ON THE TAXONOMY AND BIOLOGY OF THE OCTOCORAL-FEEDING GENUS PHYLLODESMIUM EHRENBERG, 1831 (NUDIBRANCHIA: AEOLIDOIDEA)

The aeolid nudibranch genus Phyllodesmium (Mollusca: Gastropoda)is reviewed, three new species are described and further informationon the biology, anatomy and distribution on the eight previouslyknown species is reported. The genus Ennoia Bergh, 1896 is considereda synonym of Phyllodesmium and the type species Ennoia briareusredescribed. The genus Phyllodesmium is unique amongst the aeolidsin feeding on octocoral cnidarians. This has led to the evolutionof nudibranch- zooxanthellae symbioses, zooanthellae being obtainedfrom the octocoral prey. The adaptations developed throughoutthe genus are described and possible relationships between thespecies proposed. (Received 6 January 1990; accepted 20 May 1990)     

On the first record of the genus Octopoteuthis (Cephalopoda: Octopoteuthidae) in the Sardinian Channel (central western Mediterranean Sea)

A specimen of the rare squid genus Octopoteuthis (Cephalopoda: Octopoteuthidae) from 1600 m in the Sardinian Channel (central western Mediterranean) is described. Meristic and morphological data are provided. The specimen was a spent female and details of the reproductive system and implanted spermatangia are reported. Genetic analysis of this specimen and comparison with those available for species in this genus were carried out. Due to issues associated with the taxonomy of the genus Octopoteuthis, it was not possible to identify the specimen to the species level. The taxonomy of the genus is discussed.     

On the Paleozoic bryozoans of the genus <Emphasis Type="Italic">Ascopora</Emphasis> Trautschold

Based on the study of the neotype and the astogeny of the type specimens of the species Ascopora nodosa (Fischer von Waldheim, 1837), the diagnosis and species composition of the genus Ascopora Trautschold, 1876 are emended. The genus Ascopora and three species out of the five included in this genus—A. nodosa (Fischer von Waldheim, 1837); A. sokolovae Schulga-Nesterenko, 1955; and A. latiaxis Schulga-Nesterenko, 1955—are described. A new genus, Tetrasella gen. nov., with the type species T. blanda sp. nov. is described. This genus comprises five species, transferred from the composition of the genus Ascopora. An emended diagnosis of the genus Ascoporella Krutchinina, 1986, is provided. This genus comprises nine species, of which two, A. lecta sp. nov. and A. mera sp. nov., are described as new species.     

Checklist of the species of the aseptate gregarine families Aikinetocystidae,Diplocystidae, Allantocystidae,Schaudinnellidae, Ganymedidae,and Enterocystidae

The genera and species in six families of the eugregarine suborder Aseptatorina Chakravarty, 1960, are reviewed and the presently accepted ones are listed: Aikinetocystidae Bhatia, 1930 (two genera and two species); Diplocystidae Bhatia, 1930 (one genus and eight species); Allantocystidae tocystidae Bhatia, 1930 (one genus and one species); Schaudinnellidae Poche, 1913 (one genus and one species); Ganymedidae Huxley, 1910 (one genus and one species); and Enterocystidae Codreanu, 1940 (one genus and eight species). A list of 22 synonyms and lapsi calami is also given. Species which might be of value in the biological control of disease vectors are indicated.     

Systematic significance of cytology in Cyananthus (Campanulaceae) endemic to the Sino-Himalayan region

Chromosome numbers and the morphology of members of 24 populations representing 15 species of the Sino-Himalayan endemic genus Cyananthus(Campanulaceae) were studied using karyological and numerical taxonomic techniques. The chromosome numbers of these taxa are 2n = 10, 12, 14, 24, 28, and the basic chromosome numbers for the genus are x = 5, 6, 7. All species except C. inflatus Hook. f. & Thoms. and C. microphyllus Edgew. were examined for the first time and a new ploidy level (tetraploidy) is reported in the genus. Chromosome measurement data were analyzed using cluster analysis. The relationships between three sections within Cyananthus and evolutionary trends within the genus are discussed in the light of karyological data. The cytological data suggest that Cyananthus is a relatively primitive genus in Campanulaceae and there is significant division within the genus, and polyploidization may have played an important role in the chromosome evolution and speciation of Cyananthus in the Himalayan–Hengduan Mountains.     

Psednotrichia, a genus of the tribe Senecioneae hitherto misplaced in the Astereae (Asteraceae)

Anderberg, A. A. & Karis, P. O. 1995. Psednotrichia , a genus of the tribe Senecioneae hitherto misplaced in the Astereae (Asteraceae). — Nord. J. Bot. 15: 375–379. Copenhagen. ISSN 0107–055X.
The tribal position for the little known genus Psednorrichia , is established. This monotypic genus, hitherto placed in the tribe Astereae, is a congener of Xyridopsis of the tribe Senecioneae (Asteraceae). The two species of Xyridopsis are here transferred to Psednotrichia and the new combinations P. xyridopsis and P. newtonii are made. A brief discussion of the morphology of the genus, and its systematic position within the tribe Senecioneae is provided.     

New data on the genus <Emphasis Type="Italic">Neostylopyga</Emphasis> Shelford, 1911 (Dictyoptera,Blattidae) with description of a new species from Laos

A new species of the genus Neostylopyga Shelford, 1911, N. laosana sp. n., is described from Laos, and the male genitalia are examined in detail. The type species of the genus Neostylopyga, N. rhombifolia (Stoll, 1813), is redescribed, and the taxonomic position of the genus is discussed.     

Phylogeny of Macroptilium (Leguminosae): morphological, biochemical and molecular evidence

Macroptilium (Benth.) Urban (Phaseoleae, Papilionoideae, Leguminosae) is an American genus of legumes, belonging to subtribe Phaseolinae along with other economically important genera, such as Vigna Savi and Phaseolus L. (the common bean genus). Cladistic analyses based on morphological, biochemical (storage seed proteins) and molecular (nuclear and plastid DNA sequences) data were performed on the 18 species currently ascribed to the genus, exploring several character weighting strategies. Equal weights, implied weighting and different transversion/transition costs were applied. The three data sets were first analyzed with separate partitions, and then combined into a single matrix. This study is the first one to analyze all the species of the genus from a cladistic point of view. In all the most parsimonious trees obtained, Macroptilium is monophyletic with excellent support values. Two monophyletic clades are recovered in almost all the analyses. Both are compound by nine species, and they constitute two sections of Macroptilium. Several interspecific relationships inside the genus are discussed. © The Willi Hennig Society 2007.     

Filibryum (Hypnaceae), a new moss genus with a new species from East Asia

Filibryum, a new genus of the family Hypnaceae, is described to include three species from East Asia. Filibryum ogatae and F. yakoushimae are transferred to it from the genus Glossadelphus, while F. deguchianum is a newly described species. The genus is distinguished by the absence of a central strand in the stem, prorate leaf cells, and heteroblastic and deciduous stem leaves. Molecular data suggest that the genus is closely related to Taxiphyllum and the phylogenetic position of the new genus in the Hypnaceae is supported by an approximately unbiased (AU) test.     

A taxonomic revision of the genus Tordylium L. (Apiaceae)

The four related genera: Ainsworthia Boiss., Tordylium L., Synelcosciadium Boiss. and Mandenovia Alava are revised. Data are presented from detailed gross morphology, mericarp surface features and anatomy, and palynology.
The results show: (1) Ainsmorthia and Synelcosciadium are congeneric with the genus Tordylium, and that Mandenovia is a good monotypic genus; (2) Tordylium persicum is synonymous with 7. cappadocicum and 7. aegaeum with 7. pestalozzae; (3) the genus Tordylium is best divided into subgenus Tordylium (including Synelcosciadium) and subgenus Ainsworthia (Boiss.) Drude. The latter is divided into section Condylocarpus (Hoffm.) DC, section Hasselquistia (L.) Boiss. and section Univittata Drude.
A new species of Tordylium is described, and two new combinations made. A taxonomic treatment of the genus 'Tordylium', together with a key to the species, is given.     

A record of the Plain Tiger,Danaus chrysippus,in Turkey

Summary

In this publication, a subdivision of the genus Annenica O. Boettger, 1877 sensu Auct. is proposed. One result of our study is the recognition of the genus Sprattia O. Boettger, 1883 for most of the South Anatolian species of the former genus Armenica. The genus Astrogena Szekeres, 1970, which was synonymised by H. NORDSIECK (1975: 98) with Armenica is redefined and used as a subgenus of Armenica for some species. Extensive recent collections contain new species and subspecies of this genus, which are described here.     

A new fossil silky lacewing genus (Neuroptera, Psychopsidae) from the Early Cretaceous Yixian Formation of China

A new genus and species, Undulopsychopsis alexigen. et sp. n., is described from the Early CretaceousYixian Formation of western Liaoning Province, China. This genus is probably most closely related to the Asian Cretaceous genus Kagapsychops Fujiyama, 1978. The family affinity of Undulopsychopsisgen. n. is discussed. The genus is preliminarily assigned to Psychopsidae, although it shares some character states with Osmylopsychopidae (e.g., crossveins are very scarce; Rs1 and 1A are multi-branched).     

Weintrauboa, a new genus of pimoid spiders from Japan and adjacent islands, with comments on the monophyly and diagnosis of the family Pimoidae and the genus Pimoa (Araneoidea, Araneae)

The spider genus Weintrauboa new genus (Araneae, Pimoidae) is described to place two species of pimoids from Japan and adjacent islands that were formerly classified in the linyphiid genus Labulla . Weintrauboa contortipes (Karsch) new comb., the type species, and W. chikunii (Oi) new comb. are redescribed. Parsimony analysis of morphological characters provides robust support for the monophyly of the genus Weintrauboa and corroborates the monophyly of Pimoa , Pimoidae, and the clade Linyphiidae plus Pimoidae. New diagnoses for Pimoa and Pimoidae are provided.  © 2003 The Linnean Society of London, Zoological Journal of the Linnean Society , 2003, 139 , 261–281
