INTRODUCTION In recent years the polarity of dictyosomes has been well established, both iu functional and in morphological terms (Mollenhauer & Morre, 1966; Favard, 1969). Although many of the observed differentiations across stacks of dictyosome cisternae probably result from changes in the Golgi membranes and their associated enzymes, it has only recently been possible to obtain electron-mic...

Prolific polyembryony is reported in few major taxa, but its occurrence has generated theoretical debate on potential conflict between sexual and asexual reproduction. It is, therefore, important to genetically confirm a widely cited inference, based on microscopy, that polyembryony characterizes marine bryozoans of the order Cyclostomata. Microsatellite genotyping of brooded embryos and matern...

Specimens of Neoempheria previously considered to be N. ferruginea (Brunetti, 1912) are studied and revised. Eleven new species are described from Japan, Nepal, Philippines, and Thailand; N. biceltisuta sp. n., N. bifurcata sp. n., N. bisecuriata sp. n., N. brevispathulata sp. n., N. carinata sp. n., N. cuneata sp. n., N. dilatata sp. n., N. denticulata sp. n., N. forficulata sp. n., N. latiste...

Sampling of rice fields in Kanagawa Prefecture, Japan, yielded an undescribed species the non-marine ostracod genus Sarscypridopsis McKenzie, 1977. Small marginal denticles on left valve give this its name: denticulata n. sp. Most are restricted to Africa, and based morphological characters, closest congener new is native Botswana. We therefore conclude that probably not it joins six other or p...

The present paper reports two new species of Glyphocrangon (Crustacea, Caridea, Glyphocrangonidae) collected respectively from the East China Sea and the Philippines. G. singularis sp. nov., from the East China Sea, is similar to G. fimbriata Komai & Takeuchi, 1994 with the presence of fringe of setae on dactyl of the third to fifth pereopods, but differs from G. fimbriata by the rostrum shape ...

Hoplitis bees of the Palaearctic subgenus Stenosmia (Megachilidae) inhabit deserts and semideserts between southern Spain and eastern Asia. They nest in excavated burrows in the soil and collect pollen from plant taxa that typically grow in desert areas, such as Frankenia (Frankeniaceae), Peganum (Nitrariaceae), Tamarix (Tamaricaceae) or Zygophyllum (Zygophyllaceae). The taxonomic revision of t...
