Revision of the Genera Thyca, Stilifer, Scalenostoma, Mucronalia and Echineulima (Mollusca, Prosobranchia, Eulimidae)

All species that have been described of the genera mentioned in the title are listed and their systematic position given. The species of Stilifer (with 11 species, including S. inflatus sp.n. and 5. concavus sp.n.) are parasites of starfishes. Scalenostoma (3 species) are parasites of stone corals. Thyca (with 8 species) is removed from Capulidae, and included in Eulimidae. T. hawaiiensis sp.n. is described. The species of Thyca are parasites of starfishes. The species of Mucronalia (including M. trilineata sp.n.) are probably parasites of ophiuroids and Echineulima (with 4–6 species, including E. ponderi sp.n.) are parasites of echinoids. All species are figured, their characteristics are given and their host species and distributions are listed. Keys are given to the species of each genus, except Mucronalia. The genera Stilimella Laseron and Hyperlia Pilsbry are synonymized with Scalenostoma and the genera Kiramodulus Kuroda, Granulithyca Habe and Bessomia Berry are considered subgenera of Thyca.

The Nordic Vegetation Survey - concepts and perspectives

Abstract. The background of the Nordic Vegetation Survey is outlined and the concepts for this international collaboration project are reviewed. The project includes, so far, institutions in Denmark, Faeroes, Finland, Norway and Sweden. We are setting up a common basis for a vegetation database, with a Nordic species list, exchange of data and joint revisions of important Nordic vegetation types. Progress in the Nordic Vegetation Survey is described and the future perspectives indicated.     

Generic distribution patterns in subsaharan African Rubiaceae (Angiospermae)

A survey of the distribution of the Rubiaceae from subsaharan African (continental part: 1,900 species in 164 genera; Madagascar: 675 species in 83 genera) is given. Genera are classified in nine major distribution patterns, most of which are further subdivided. General statistics of the data are given, and the patterns are discussed in the light of (i) the phytogeographical literature relating to tropical Africa and (ii) existing evolutionary hypotheses on the Rubiaceae.     

Indian species of Drosophilidae,exclusive of the genus Drosophila

An account is given of five species representing four genera of the family Drosophilidae, one of which is described as new and two are new records from India. The Indian species of Drosophilidae (excluding Drosophila species) are listed and a key to the genera is provided.     

Progress in Taxonomy of the Apicomplexan Protozoa

In 1987, 4516 species and 339 genera of the phylum Apicomplexa had been named. They consisted of the gregarines (subclass Gregarinasida) (1624 named species and 231 named genera), the hemogregarines (family Haemogregarinidae) (399 species and 4 genera), the eimeriorins (order Eimeriorida) (1771 species and 43 genera), the hemospororids (order Haemospororida) (444 species and 9 genera), the piroplasmids (order Piroplasmorida) (173 species and 20 genera), and a few others (105 species and 32 genera). The first apicomplexan protozoon was seen by Antony van Leeuwenhoek; in 1674 he saw oocysts of Eimeria stiedai in the gall bladder of a rabbit. The first member of the phylum to be named (by Dufour in 1828) was Gregarina ovata in earwigs. During the quarter century 1826–1850, 41 species and 6 genera of Apicomplexa were named. These numbers increased progressively. In the quarter century 1951–1975, 1873 new species and 83 new genera were named. Data are given for the numbers of named species and genera of apicomplexan protozoa of each group known in 1850, 1875, 1900, 1925, 1950, 1975, and 1987.
