Taxonomy of the Neotropical Genus Americabaetis,New Status (Insecta: Ephemeroptera: Baetidae)

Americabaetis (Insecta: Ephemeroptera: Baetidae), previously considered synonymous with Acerpenna, is reinstated and given generic rank. The genus differs from Acerpenna in lacking hindwings, gills on abdominal segment 1, and a conical process between the male genital forceps, and in possessing apically rounded gills on abdominal segment 7. The genus has a general Neotropical distribution with a northern limit in east-central Mexico. Five new species of Americabaetis are described from South America: A. alphus, new species, from Argentina, Bolivia, Brazil, Chile, and Paraguay; A. labiosus, new species, from Brazil, Paraguay, and Uruguay; A. longetron, new species, from Brazil, Paraguay, and Uruguay; A. maxifolium, new species, from Paraguay; and A. titthion, new species, from Brazil. Americabaetis boriquensis, new combination; A. intermedius, new combination; A. naranjoi, new combination; A. pleturus, new combination; and A. robacki, new combination, are reviewed.

Systematic studies on the Pompilidae occurring in Japan: Genus Agenioideus Ashmead (Hymenoptera), supplement

Two species of the pompilid genus Agenioideus occurring in Japan are described: A . ( Agenioideus ) kokyo and A . ( A .) cinctellus . The former is new to science and the latter is recorded from Japan and Taiwan for the first time. A brief summary of the biology of A. cinctellus , distinguishing characters between A. ( A. ) ishikawai Shimizu, 1989 and its relatives, and a key to all Japanese species of this genus are presented. Psammochares cinctellus f. rufa Haupt, 1938 and A . ( A. ) pacificus Lelej, 1994 are newly synonymized with A. cinctellus . A new combination is proposed: A . ( A .) maculipes (Smith, 1870) (= Pompilus maculipes Smith), which is found in Southeast Asia to South Asia. Agenioideus ishikawai is newly recorded from Korea and China.     

A new isidiate species of Catillaria from the Netherlands

Abstract:A new lichen species, Catillaria nigroisidiata, is described from the Netherlands: it is the first isidiate species known in the genus and has been collected growing on granite on dykes in the north-eastern part of the country. This new species is easily overlooked because of the completely black appearance. A key toCatillaria s.str. in western Europe is provided.

A new genus and species are described. The genus Philogalleria Cameron is revised: six species (five of them new) are recognized, described and keyed. Rhynchobanchus is newly recorded from Britain and a key is given to its European species.     

New fossil Progonocimicidae (Hemiptera: Coleorrhyncha: Progonocimicoidea) from the Upper Mesozoic of northeastern China,with a phylogeny of Coleorrhyncha

A new Progonocimicidae species, Cicadocoris anisomeridis sp.n. , with asymmetrical tegmina is described from the Middle Jurassic Jiulongshan Formation in northeastern China. This is the fifth report of Coleorrhyncha from China. A cladistic analysis based on a combination of fossil and extant taxa clarifies the phylogenetic status of the new fossils and allows the reconstruction of inter‐subfamily relationships within the suborder Coleorrhyncha. Coleorrhyncha is monophyletic and divided into two main clades. Progonocimicidae comprises a monophyletic lineage, to which the new fossils belong. The broadly conceived Progonocimicinae and Cicadocorinae, as recognized by earlier authors, are not supported. The monophyly of the family Karabasiidae is also not supported, and its two constituent subfamilies Hoploridiinae and Karabasiinae are raised to family rank. Hoploridiidae is found to be sister group to all extant moss bugs, and Karabasiidae is found to be the monophyletic sister group to Hoploridiidae + all extant moss bugs.

A New Variant of the Mouse Akp1 Locus

A new electrophoretic migration type of alkaline phosphatase 1 (Akp1) was found on the cellulose acetate electrophoresis for kidney and liver homogenates of KWHM mouse, a newly established inbred strain derived from the Korean wild mouse (Mus musculus molossinus). This new type of alkaline phosphatase 1 was distinguished from previously reported AKP1A and AKP1B types in the mouse, and tentatively named AKP1C. In genetic analysis by mating experiments between KWHM and C57BL/6J (AKP1A) or BALB/cA (AKP1B), the phenotypic segregation ratios of AKP1A : AKP1AC : AKP1C or AKP1B : AKP1BC : AKP1C were 1 : 2 : 1 in both groups of F2 generations. It was therefore concluded that AKP1C type is controlled by Akp1c allele which is codominant with Akp1a and Akp1b alleles.     

A new fourier transform approach for protein coding measure based on the format of the Z curve

MOTIVATION: At the core of most protein gene-finding algorithms are the coding measures used to make a decision on coding/non-coding. Of the protein coding measures, the Fourier measure is one of the most important. However, due to the limited length of the windows usually used, the accuracy of the measure is not satisfactory. This paper is devoted to improving the accuracy by lengthening the sequence to amplify the periodicity of 3 in the coding regions. RESULTS: A new algorithm is presented called the lengthen-shuffle Fourier transform algorithm. For the same window length, the percentage accuracy of the new algorithm is 6-7% higher than that of the ordinary Fourier transform algorithm. The resulting percentage accuracy (average of specificity and sensitivity) of the new measure is 84.9% for the window length 162 bp. AVAILABILITY: The program is available on request fromC.- T.

A comparison of artificial diets for mass rearing Brontispa longissima (Coleoptera: Chrysomelidae) as hosts for the larval and the pupal parasitoids

The coconut hispine beetle, Brontispa longissima (Gestro) (Coleoptera: Chrysomelidae) is a serious pest of coconut palm. In this study, we developed an artificial diet for B. longissima so that the beetle could be used as a host for rearing two of its parasitoids, Asecodes hispinarum Boucek (Hymenoptera: Eulophidae) and Tetrastichus brontispae Ferrière (Hymenoptera: Eulophidae). The new artificial diet represents an improvement of our previous diet, which we used as a control. When beetle larvae were reared on the new diet, which contains cysteine but not cellulose powder and has twice as much coconut leaf powder as in the control, the adult emergence was 71% (approximately 2 times that in the control). We also examined the suitability of beetles fed on the new diet as hosts for the larval parasitoid A. hispinarum and the pupal parasitoid T. brontispae. The percentage of wasps that emerged from hosts that were fed the new diet was higher than that from the control-fed hosts. The new diet allowed both A. hispinarum and T. brontispae to produce adult wasps of the next generation, whereas the control only allowed T. brontispae to produce the next generation. These results suggest that the new diet is suitable for B. longissima and will facilitate mass-rearing of A. hispinarum and T. brontispae.     

Notes on African species of the genus Anisopappus Hook. & Arn. (Asteraceae)

Two new species of the genus Anisopappus Hook. & Arn. (Asteraceae) are described: A. athanasioides Paiva & Ortiz, from Angola, and A. pseudopinnaididus Ortiz & Paiva, from Namibia. The morphological variability of the A. chinensis-A. africanus complex is studied and two new combinations are proposed: A. chinensis subsp. africanus (Hook, fil.) Ortiz & Paiva and A. chinensis subsp. lobatus (Wild) Ortiz & Paiva.     

Microsatellites for the mangrove tree Avicennia germinans (Acanthaceae): Tools for hybridization and mating system studies

? Premise of the study: We developed a new set of microsatellite markers for the black mangrove Avicennia germinans, to provide new informative tools for further studies of the mating system, interspecific hybridization, and population genetics. ? Methods and Results: We used the microsatellite-enriched library approach to isolate and characterize 25 new primer pairs. Sixteen of them are polymorphic, showing a variable degree of variation in A. germinans, while nine were monomorphic in the samples examined. Eight exhibited private alleles in A. schaueriana. ? Conclusions: These results indicate that these new microsatellite markers will be useful molecular tools for further studies of A. germinans and A. schaueriana population genetics, mating systems, and hybridization.     

Enzyme entrapped inside the reversed micelle in the fabrication of a new urea sensor

A new improvised urea sensor is described. The new sensor makes use of entrapment inside reversed micelles as a method for enzyme immobilization and glass electrode for the purpose of sensing. Urea content in clinical blood samples has been estimated using this new sensor. Agreement of the results thus obtained with those from clinical methods gives credence to the new sensor.

A new species of the genus <Emphasis Type="Italic">Sequoiadendron</Emphasis> Buchholz (Cupressaceae) from the Upper Cretaceous of the Enmyvaam River Basin,Central Chukotka

A new conifer species, Sequoiadendron tchucoticum A. Sokolova from the Emuneret Formation on the Enmyvaam River (Anadyr River Basin) is described. It is established based on a thorough study of the morphology and epidermal features of shoot impressions, using scanning electron microscopy. The new species has polymorphic shoots with helical branching and three main leaf types: scalelike, subulate, and falcate. Leaves are amphistomatic; amphicyclic stomata are mostly obliquely arranged; ordinary epidermal cells are rectangular, frequently with oblique end walls, and their length-to-width ratio reaches 15: 1. Shoots of the new species prevail among conifers of the Ust’-Emuneret Assemblage. The age of the deposits enclosing the assemblage is debated; according to the latest data, it is estimated as Santonian–Early Campanian.     

Succinapion telnovi n. gen. et n. sp. of the tribe Kalcapiini (Coleoptera: Brentidae: Apioninae) in Baltic amber

A new genus and species, Succinapion telnovi n. gen. et n. sp. (Coleoptera: Curculionoidea: Brentidae: Apioninae: Kalcapiini) is described and illustrated from Upper Eocene Baltic amber. The new genus is similar to the genus Melanapion Wagner, 1930 but differs from it in having femora ventrally with spine at distal 1/3, simple claws, a longer rostrum, elytra weakly widened towards apex, longer antennae and slightly narrower elytral striae.http://www.zoobank.org/urn:lsid:zoobank.org:pub:2A95C49D-5589-4ACA-8A87-0DDF635BA25E     

Three new species of Stiphrornis (Aves: Muscicapidae) from the Afro-tropics,with a molecular phylogenetic assessment of the genus

We describe three new species of forest robin in the genus Stiphrornis; two from West Africa and one from the Congo Basin. Each species represents a distinct phylogenetic lineage based on genetic analysis. In addition to genetic differentiation, each new species is diagnosable from other Stiphrornis lineages by morphology, and by plumage. One of the new species appears to be restricted to the Central and Brong-Ahafo Regions of Ghana, and another is restricted to Benin and the Central Region of Ghana. In Ghana, these two new species presumably come into contact with Stiphrornis erythrothorax (Western Region of Ghana and westward), and there is evidence that one of the new species has a distinguishably different song from erythrothorax. The distribution of the third new species is primarily on the south bank of the Congo River, near the city of Kisangani. Recognition of these species provides additional evidence that Afrotropical forests are harbouring substantial cryptic diversity, and that our knowledge of the drivers of this diversity remains poorly documented across the region.

Systematics of the spider genus Metabus O. P.-Cambridge, 1899 (Araneoidea: Tetragnathidae) with additions to the tetragnathid fauna of Chile and comments on the phylogeny of Tetragnathidae

The spider genus Metabus (Tetragnathidae) previously included nine species: the type M. gravidus O. P.-Cambridge, 1899 – junior synonym of Leucauge ocellata (Keyserling) – from Central America and eight species from Chile. In this paper, the classification of the Metabus species-complex is revised, and two new genera, with three new species and five new combinations, are described. Allende gen. nov. is created for four Chilean species not congeneric with the type of Metabus : the type A. puyehuensis sp. nov. , A. patagiatus (Simon) comb. nov. , A. nigrohumeralis (F. O. P.-Cambridge) comb. nov. and A. longipes (Nicolet) comb. nov. Further additions to the Chilean fauna are under the new genus Mollemeta gen. nov. – created for M. edwardsi (Simon) comb. nov. – and three new species of Chrysometa : C. acinosa sp. nov. , C. levii sp. nov. and C. maitae sp. nov. Metabus now includes four species: M. ocellatus (Keyserling) comb. nov. , M. debilis (O. P.-Cambridge) comb. nov. , M. ebanoverde sp. nov. and M. conacyt sp. nov. All of these species were included in a phylogenetic analysis of 38 tetragnathid and 12 orbicularian outgroup terminals scored for 105 morphological and behavioural characters. The results suggest that Metabus as previously circumscribed is polyphyletic. The phylogenetic relationships within tetragnathids are briefly discussed. © 2007 The Linnean Society of London, Zoological Journal of the Linnean Society , 2007, 151 , 285–335.
