Poeciloderrhis Stål (1874) was first described without reference to the included species and without morphological details. The genus was described in a key for the American Epilampra, which left only Asian-Australian species in the genus. Roth (1970) was the first to separate Poeciloderrhis from Epilampra with strong morphological characters. In this contribution, three species of Poeciloderrh...

A new genus and three new species of the picobiin quill mites (Cheyletoidea: Syringophilidae) are described from passeriform birds in Guyana, Phipicobia pygiptilae gen. nov. and sp. nov. parasitizing Pygiptila stellaris (Spix) (Thamnophilidae), Rafapicobia thamnophili sp. nov. from Thamnophilus insignis Salvin et Godman (type host), Myrmoborus leucophrys (Tschudi), Myrmeciza ferruginea (St. Mül...

The European mistletoe, Viscum album, is the most common consumed adjuvant among cancer patients in Europe. Its success warrants a report on three most apparent mistletoes found in Borneo Island, namely Scurrula ferruginea, Macrosolen cochinchinensis, and Dendrophthoe curvata. The traditional and pharmacological uses of these mistletoes include antibacterial, anticancer, antiviral, antihyperten...

Two morphologically distinct extracellular stalk fibers produced by Gallionella ferruginea were compared by electron microscopy and elemental analysis. The thick- and fine-fiber stalks were different in structure on a micrometer scale and in the site on the mother cell to which they were attached, but on a nanometer scale they were similar in ultrastructure and in the elemental composition of t...

ETHNOPHARMACOLOGICAL RELEVANCE Tuberculosis (TB), caused by Mycobacterium tuberculosis (MTB) is the most commonly notified disease and the fifth largest cause of mortality. One in 10 cases is resistant to treatment in some areas. Several plants are used locally to treat TB-related disease. AIMS OF THE STUDY The aim was to screen selected South African medicinal plants used to treat TB and rel...

Resource partitioning has been hypothesized to play a role in the maintenance of tree diversity in tropical forests. We looked for evidence of light and soil moisture partitioning among seedlings of four native Malagasy tree species, the pioneer, gap-adapted species Harungana madagascariensis and the three shade-tolerant species Ocotea cymosa, Stephanostegia capuronii and Uapaca ferruginea. Fou...

Flowering plants commonly separate male and female function in time, but rarely are the two stages synchronized within and among individuals. One such temporal mating system is duodichogamy in which each plant produces two batches of male flowers that are temporally separated by a batch of female flowers, with within-individual synchrony and among-individual asynchrony to ensure mating partners...
