| An account is given of 13 species of freshwater planarians from the family Dugesiidae, based on samples from new localities in New Zealand and Australia; these include four newly described and one problematic species. In the case of three species, the material described represents the second series of specimens available since the material used in the original descriptions of these species, as a result of which our understanding of the morphology of the animals can be expanded. In other cases, the new material also contributed to a more detailed understanding of the anatomy of the species. The study concludes with detailed distribution maps for the species examined, including not only the new distributional records described in the paper but also... |

| Glands of the reproductive system are important for taxonomical identification of flatworms. We studied the histology and histochemical characteristics of the glands of the male copulatory apparatus in Girardia anderlani (KAWAKATSU & HAUSER, 1983). Specimens were fixed in reproductive state, i. e. during and following copulation at four, eight, 12 and 16 hours intervals. Secretory cells were distinguished on the basis of secretion morphology and their staining properties, using trichrome methods and histochemical reactions. Twelve secretory cell types and five main types of secretions were identified in the male copulatory apparatus: glycoproteic with and without tryptophan; glycosaminoglycidic; neutral mucopolysaccharidic; and proteic. Compared to... |
