| The current classification system for the Monocelididae which is based on the character "presence or absence of an accessory prostatoid organ" divides the family into two subfamilies, namely the Minoninae and the Monocelididinae. However, other characters relating to the structure of the male copulatory bulb and to karyotypes do not support this division. Monocelidid male copulatory bulbs can be either of the simplex or the duplex-type, and if this character is mapped onto the current classification, then both subfamilies contain species with either type of copulatory bulb. We therefore decided to construct an independent phylogeny for the Monocelididae using nucleotide-sequence data of the gene coding for the 26/28S rDNA. Distance and parsimony-based... |

| Four new species of the genus <i>Archilina</i> Ax are described from tropical areas: <i>A. euglypta</i> n. sp. and <i>A. batiae</i> n. sp. from Red Sea; <i>A. stylifera</i> n. sp. and <i>A. opisthobursa</i> n. sp. from the Carribean (Puerto Rico). The karyotypes of all species are given: three of them have karyotypes derived from the basic set of the family Monocelididae. A sister-species relationship is proposed for the Carribean species based on the backwater position of the bursa. Because of this feature, the genus diagnosis is modified. The two Carribean species are considered as a separate evolutionary line within the genus <i>Archilina</i> |

| The composition and dynamics of meio- and macrofauna in a subtidal location at Zoagli (Ligurian Sea, Italy) were followed for an annual cycle (from January 1991 to January 1992). Polychaete recruitment occurred during spring and late summerautumn. The increase in density of predatory nematodes (dominated by <i>Oncholaimellus, Viscosia, Mesacanthion </i>and <i>Chromaspirina</i>) and turbellarians corresponded to the collapse of macrobenthos recruits. Such alteration was probably due to predation by turbellarians and predator-nematodes during and immediately after the macrofaunal larval settlement. Differences in predator pressure were observed between spring and autumn. Conversely, no significant impact was observed on bivalves. The... |

| The family Archimonocelididae Meixner, 1938 has been revised. The family contains two subfamilies, each comprising two genera: the Archimonocelididae with <i>Archimonocelis</i> Meixner, 1938 and <i>Meidiama</i> Marcus, 1946, and the Calviriinae subfam. nov. with <i>Asilomaria</i> Karling, 1966 and <i>Calviria</i> gen. nov. with 20, 2, 1 and 3 species, respectively, 13 of which are new to science.The type species of the family is redescribed. Material of all the Archimonocelididae genera has been studied and supplementary remarks are made on some known species. The karyotype of 14 species is described.<i>Archimonocelis</i> has a cosmopolitan distribution while <i>Meidiama</i> is... |

| <i>Monocelis longistyla</i> sp.n. from littoral sandy habitats of the Mediterranean is described. The karyotypes of <i>Monocelis fusca, M. lineata</i> and <i>M. longistyla</i> sp.n. were analysed. A basic karyotype for the genus Monocelis is postulated and its probable evolution from the basic karyotype of the family Monocelididae and within the genus is discussed. The karyotype of <i>M. longistyla</i> seems to have evolved from the basic Monocelis karyotype by pericentric inversions. However from the analysis of the karyotype in different populations of <i>M. lineata</i> the species appeared not to be homogeneous (European populations versus the Canadian population). |

| Mechanisms of karyotype evolution in the Monocelididae (<i>Turbellaria Proseriata</i>). Within the Proseriata (Turbellaria: Seriata), the family Monocelididae displays several interesting patterns of chromosomal evolution. A basic set of n = 3 -made up or one large metacentric, one medium-sized metacentric and one small clearly heterobrachial chromosome -has been detected. It is widely distributed in species pertaining to both the subfamilies in which the Monocelididae are subdivided. From this basic set, other complements -either with n = 3 or n > 3 -would be originated.Several karyological mechanisms or common occurrence within the family (translocations, small chromosome rearrangements involving the centromere, genome growth) have been... |
