Gymnolaemate bryozoans from the Algarve (southern Portugal): new species and biogeographical considerations

Three sampling surveys were carried out, by SCUBA diving, in the Algarve (southern Portugal) in December 2007. A total of 57 species of gymnolaemate Bryozoa were identified. Of these, eight species were new to science ( Mollia cristinae sp. nov., Hippoporina teresae sp. nov., Schizoporella spinosa sp. nov., Fenestrulina inesae sp. nov., Celleporina derungsi sp. nov., Dentiporella saldanhai sp. nov., Rhynchozoon celestinoi sp. nov. and Rhynchozoon rosae sp. nov.). Another 16 species are cited for the first time in Portuguese waters; of these, Stephanollona contracta is cited for the first time in European continental waters. Reference material deposited in several collections was also revised, and lectotypes and paralectotypes were selected for Mollia multijuncta and Dentiporella sardonica , species subjected to diverse interpretations. In addition Rhynchozoon revelatus was found to be a junior synonym of D. sardonica . The species collected in the study area reflect the existence of Lusitanian, Mauretanian and Mediterranean influences; the latter influence is of interest as the Mediterranean species found were previously considered endemic to the Mediterranean Sea and are usually found in shallow waters. Finally, a large degree of intracolonial variability was observed in some of the species studied, especially in Stephanollona armata , which may be taken into account in studies of the geographical variability and differentiation of cryptic species.

Species of genus Schizotheca Hincks (Bryozoa, Cheilostomata) described in the Atlantic‐Mediterranean region, with notes on some species of Parasmittina Osburn

Material held in collections, originally ascribed to the genus Schizotheca and originating from the NE Atlantic and Mediterranean, is revised. Two new species are described: Schizotheca carmenae sp. nov. from Azores and Portugal, originally cited as Strophiella tubigera [sic], and Schizotheca buski sp. nov. from Cape Verde and Brazil, originally cited as Schizotheca fissa. Schizotheca talismani, also from Cape Verde, is redescribed from original material and transferred to the genus Parasmittina. The Atlantic species Schizotheca tuberigera is redescribed and a new synonymy is established. Schizotheca aviculifera, from Morocco, is also redescribed and a lectotype designated. A lectotype is also chosen for Schizotheca fissa, type species of the genus. Schizotheca lepida, from north France, is considered to be an unrecognizable species.

Presence of rhizoids in two species of the genus Bowerbankia (Bryozoa: Ctenostomata) and their systematic relevance

The existence is reported of rhizoids in specimens of Bowerbankia pustulosa and Bowerbankia citrina collected from different Iberian locations. The structure of these rhizoids differs from that of other fixation structures previously reported in Bowerbankia and redescribed here. Rhizoids in both species are probably homologous with those of Amathia, supporting the close relationship between these two genera.

Three new species of Iberian cheilostomate Bryozoa

Three new species of Iberian cheilostomate bryozoans are described from material held in our own collection as well as in the bryozoan collection in the Museo Nacional de Ciencias Naturales, Madrid. Chaperiopsis hirsuta sp. nov., from the Mediterranean, is the second species of this genus in European waters. Metroperiella gay sp. nov. and Schizoporella artabra sp. nov. are described from material collected in Galicia (north-western Spain).

Schizomavella grandiporosa and Schizomavella sarniensis: Two Cryptic Species

The type specimen of Schizomavella grandiporosa Canu and Bassler, 1925, has been located in the MNHN, Paris, and reveals that this species is closely similar to Schizomavella sarniensis Hayward and Thorpe, 1995. All available material of both species has been studied, including SEM-photographies. Morphometric analysis has been performed using n-MDS and tested with ANOSIM. Results confirm the separation of the two species which are, however, morphologically very similar. The geographic distributions overlap with S. grandiporosa being more southern (northwest Spain–Morocco–Algeria) than S. sarniensis (English Channel–southern Portugal).

A new species of the genus Celleporella (Bryozoa: Cheilostomatida) from the European Atlantic Coast

Until recently, Celleporella hyalina (Linnaeus, 1767) was the only species of this genus cited from the European Atlantic coast. This species is found all around the world and is generally considered to be cosmopolitan and morphologically very adaptable (Pinter, 1973, p. 437), which has led to the description of many varieties (e.g. Busk, 1854; Hincks, 1880). Some of these were later considered simply as growth forms or the result of diierent degrees of calci¢cation, while others have been elevated to species level. Fernandez Pulpeiro (1982, 1986) pointed out the unusual aspect of the sinus in the autozooids of some specimens collected from the Galician coast, which were provisionally, and with reservations, identi¢ed as C. hyalina, and which were later described as a new species: Celleporella angusta Alvarez, 1991, found on the Galician and Cantabrian coasts (Alvarez, 1991; Fernandez Pulpeiro & Reverter Gil, 1992) and which has also recently been found in the north of Brittany and Arcachon (Reverter et al., 1995). Between 1995 and 1996 systematic sampling of bryozoans was carried out on the northern coasts of Galicia (north-west Spain; see Figure 1). Material from the genus Celleporella was found at almost all of the sampling sites, but some of this was not able to be assigned to any of the presently known species. Studies carried out led to the description of a new species as detailed in this paper. J.Mar. Biol. Ass. U.K. (1999),79, 51^55 Printed in the United Kingdom

A new name for Puellina parva Reverter & Fernández, 1996 (Bryozoa, Cheilostomatida)

Over 10 years ago, we published a paper on cribrimorph Bryozoans from the Rı́a de Ferrol (NW Iberian Peninsula) (Reverter and Fernández 1996) in which a new species of the genus Puellina was described, named P. parva with reference to the small size of both zooids and observed colonies. This species is further characterized by a circular pericyst with seven broad costae, a suboral peristome formed by the costal ridge of the distalmost pair of costae, a D-shaped orifice with six oral spines (four in ovicellate zooids), and an apertural bar with two large lacunae in each corner, and two median tubercles bearing pelmatidia. We have now discovered that Puellina parva is preoccupied. Winston and Håkansson (1986) had earlier described another, different, species from Florida, which they named Cribrilaria parva. It was characterized by the small size of the zooids, a frontal shield made up to five or six pairs of costae, the second pair raised and enlarged to form a curved or Vshaped ridge, a D-shaped orifice with six oral spines (four in ovicellate zooids), and an apertural bar with a central pore, not enlarged. This species belongs in the genus Puellina, as redefined by Bishop and Househam (1987), and its valid name is thus Puellina parva (Winston and Håkansson 1986). In consequence, our name becomes a junior secondary homonym and must be substituted (ICZN, Art. 53.3, 57.3, 60). We propose Puellina nana nom. nov. as a new name for Puellina parva Reverter & Fernández, 1996; description, figures and material remain the same as in the original paper (Reverter & Fernández 1996) for Puellina parva (see ICZN recommendation 60A). We are most grateful to Hans De Blauwe, who detected, and drew our attention to, the homonymy.
