Type Collection

A Liberian collection of the smut fungus Sporisorium rhytachnes-rottboellioidis on Rhytachne rottboellioides, hitherto known only from the type collection from Uganda, has been discovered. The type specimen of S. rhytachnes-rottboellioidis was re-studied. A new combination, Anthracocystis rhytachnes-rottboellioidis, is proposed to accommodate this fungus. The new record extends the geographical range of A. rhytachnes-rottboellioidis from Central East Africa to West Africa. A new combination, Anthracocystis urelytri, is introduced to accommodate Sorosporium urelytri. A key to the smut fungi of Anthracocystis on Rhytachne and Urelytrum is provided.

Type Specimen

The giant millipede Pachybolus tectus Cook, 1897, described from Zanzibar, East Africa, and never re-collected till now, is re-described based on newly collected specimens from Cameroon, West Africa. The species is transferred to the genus Pelmatojulus Saussure, 1860, and compared with the most similar congener, P. togoensis (Cook, 1897). The type specimen of P. tectus, which no longer exists, probably was mis-labelled. An overview of the distribution of Pelmatojulus species and records of the genus from Cameroon are given, including P. brachysternus (Cook, 1897) as new to the fauna of Cameroon. Pelmatojulus insignis (Saussure, 1859) and P. togoensis are recorded as new to the fauna of Ghana.

First Time

Sporisorium elegantis, a smut fungus on Thelepogon elegans, is reported for the first time from Benin (West Africa). Based on this collection, an emended description and illustration of this rare species are provided. The geographical distribution of Sporisorium elegantis is documented for Benin, Nigeria and India. The disjunctive occurrence of this species between (western) Africa and India is interesting, though not exceptional in smut fungi. The mechanisms responsible for such a distribution pattern are not known.

Scanning Electron

The size, shape and surface morphology of human erythrocytes (RBC) were examined by scanning electron microscopy (SEM), of the fixed material directly and by transmission electron microscopy (TEM) of surface replicas to compare the relative merits of these two observational procedures for this type specimen.A sample of human blood was fixed in glutaraldehyde and washed in distilled water by centrifugation. The washed RBC's were spread on freshly cleaved mica and on aluminum coated microscope slides and then air dried at room temperature. The SEM specimens were rotary coated with 150Å of 60:40- gold:palladium alloy in a vacuum evaporator using a new combination spinning and tilting device. The TEM specimens were preshadowed with platinum and then rotary coated with carbon in the same device. After stripping the RBC-Pt-C composite film, the RBC's were dissolved in 2.5N HNO3 followed by 0.2N NaOH leaving the preshadowed surface replicas showing positive topography.

Refugee Protection

This introductory chapter begins by presenting the book’s structure in section A. Section B then delineates the book’s contours, outlining four aspects of refugee protection in Africa that are not addressed. Section C provides context, with a contemporary overview of the state of refugee protection in Africa. It also looks at the major aspects of the refugee situations in each of Africa’s principal geographic sub-regions: East Africa (including the Horn of Africa), Central Africa and the Great Lakes, West Africa, Southern Africa, and North Africa. Section D then concludes with an outline of the theoretical approach to regime relationships employed throughout the book.

The genus Xylaplothrips is re-diagnosed, 11 species are listed as appropriately included in this genus of which three are new combinations from Haplothrips (X. acaciae; X. collyerae; X. gahniae). A further six species are listed as incertae sedis within Xylaplothrips and a key is provided to the four species of this genus known from Australia including X. anarsius sp.n. The genus Mesandrothrips is recalled from synonymy with Xylaplothrips, and a list is provided of 20 appropriately included species of which 14 are new combinations from Xylaplothrips (M. caliginosus; M. clavipes; M. darci; M. dubius; M. emineus; M. flavitibia; M. flavus; M. inquilinus; M. montanus; M. pictipes; M. pusillus; M. reedi; M. subterraneus; M. tener), and one is a new combination from Haplothrips (M. inquinatus). A key is provided to 10 species of this genus known from Australia, including three species transferred from Haplothrips, together with M. austrosteensia sp.n., M. googongi sp.n., M. kurandae sp.n., M. lamingtoni sp.n. and M. oleariae sp.n. The type species, M. inquilinus, is widespread across Southeast Asia as an invader of thrips galls, and Haplothrips darci Girault based on a single female from Queensland is considered closely related.

The purpose of this announcement is to effect the valid publication of the following new names and new combinations under the procedure described in the Bacteriological Code (1990 Revision). Authors and other individuals wishing to have new names and/or combinations included in future lists should send three copies of the pertinent reprint or photocopies thereof to the IJSEM Editorial Office for confirmation that all of the other requirements for valid publication have been met. It is also a requirement of IJSEM and the ICSP that authors of new species, new subspecies and new combinations provide evidence that types are deposited in two recognized culture collections in two different countries (i.e. documents certifying deposition and availability of type strains). It should be noted that the date of valid publication of these new names and combinations is the date of publication of this list, not the date of the original publication of the names and combinations. The authors of the new names and combinations are as given below, and these authors' names will be included in the author index of the present issue and in the volume author index. Inclusion of a name on these lists validates the publication of the name and thereby makes it available in bacteriological nomenclature. The inclusion of a name on this list is not to be construed as taxonomic acceptance of the taxon to which the name is applied. Indeed, some of these names may, in time, be shown to be synonyms, or the organisms may be transferred to another genus, thus necessitating the creation of a new combination.
