Twelve mountain zebra which were culled at monthly intervals on the farm " Kelpie " in South West Africa/Namibia were examined for helminths. The zebras varied in age from 2-15 years, the middle group of which, aged 4-7 years, had the highest worm burdens. Fourteen species of nematodes belonging to the families Atractidae , Strongylidae , Oxyuridae , Setariidae and Spiruridae were recovered. Th...

At least 95 species of Pamphagidae belonging to 17 genera are known in North Africa. Taxonomic status is fairly known, with some exception, mainly due to scarcity of available specimens of some genera in museums and collections. In this paper, the author proposes a new key to genera and reports the annotated list of all the known species, based on specimens examined in different European museum...

Nineteen species of gastro-intestinal nematodes were recovered from 10 Burchell's zebra. These include: Cyathostomum alveatum, C. montgomeryi and C. tetracanthum; Cylicocyclus auriculatus, C. gyalocephaloides, C. insigne and C. triramosus; Cylicodontophorus schürmanni and Cylicodontophorus n.sp., Cylicostephanus bidentatus, C. calicatus and C. minutus; Poteriostomum ratzii, Craterostomum acutic...

The arrangement of genes in the mitochondrial (mt) genomes of most insects is the same, or near-identical, to that inferred to be ancestral for insects. We sequenced the entire mt genome of the small pigeon louse, Campanulotes bidentatus compar, and part of the mt genomes of nine other species of lice. These species were from six families and the three main suborders of the order Phthiraptera. ...

The bethylid genus Foenobethylus Kieffer, 1913, unstudied for almost a century, is redescribed and assigned to the subfamily Pristocerinae based on a preliminary phylogenetic assessment. Four new species: F. bidentatus n. sp. (Brunei), F. elongatus n. sp. (Malaysia), F. emiliacasellae n. sp. (Thailand), and F. thomascokeri n. sp. (Malaysia) are described, based on males only, as females remain ...

Se reportan nuevos registros y ampliaciones en el área de distribución Harpagus bidentatus, Glaucidium sanchezi, Attila spadiceus, Cyanolyca nana, Oreoscoptes montanus Peucedramus taeniatus. Estas seis especies aves fueron registradas bosque mesófilo montaña del estado Hidalgo, México. Dos estas (G. sanchezi C. nana) son restringida, lo que eleva a tres número restringida la zona. Esto enfatiza...

in iran, cheyletid mites (acariformes: cheyletidae) were collected over 15 years (1996–2010) in stored cereal. samples were collected from silos, flour-mills, barn and rice-mills in 12 provinces scattered throughout the north,  centre, east and west of iran. 8 genera and 13 species were recorded: acaropsellina sollers (kuzin, 1940), cheletomorpha lepidopterorum (show, 1794), cheyletus bidentatu...

Molluscs, both gastropods and bivalves, appear to disproportionately influence the dynamics of salt marsh habitats. Bivalves typically are facilitators positively affecting the growth and survival of marshes, but gastropods may have unanticipated top-down effects through direct consumption of the predominant marsh vegetation, Spartina alterniflora. Natural, elevational differences in S. alterni...
