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... |

Les polyclades sont des vers plats de vie libre, presque exclusivement marins et très peu connus en Tunisie. Ce travail a pour objectif de faire le point des connaissances actuelles sur les espèces de polyclades rencontrées en Tunisie. La prospection de quelques stations au Nord du pays nous a permis de récolter huit espèces dont trois signalées pour la première fois en Tunisie. Il s’agit de Discocelis tigrina, Prostheceraeus moseleyi et Pseudoceros maximus. Une description des espèces collectées ainsi que leur distribution géographique en Tunisie sont présentées dans ce travail. La position taxonomique de chaque espèce est également donnée et son habitat est décrit. |

The Brazilian Atlantic Forest harbors the world's richest areas of land planarians (Platyhelminthes: Tricladida). Nevertheless, the number of undiscovered species from this biological unit remains seemingly high. Herein we describe Geoplana piriana Almeida & Carbayo, sp. nov. from the state of Rio de Janeiro, and Geoplana tingauna Kishimoto & Carbayo, sp. nov. from the state of Santa Catarina. Each species shows a dorsum with a unique color pattern among Geoplaninae species. Their internal morphology also differs: G. piriana sp. nov. shows a unique combination of features, including an extrabulbar, non-bifurcated prostatic vesicle, a non-folded male atrium, a horizontal, cylindrical penis papilla, a female atrium anteriorly narrowed, and... |
