Orthophrys pygmaeum is recorded first time for the Spanish fauna from Tarifa (Cadiz) and Lanzarote (Canary Islands). New data about its biology, taxonomy and hypothesis about its distribution are given. An annotated Appendix of the ibero-macaronesian Saldidae and a check list of the Iberian Leptopodomorpha are presented. [ABSTRACT FROM AUTHOR]

The seasonal cycle of a mixed seagrass meadow of Cymodocea nodosa and Caulerpa prolifera and of the associated ichthyofauna was studied at Playa Dorada (Lanzarote, Canary Islands, eastern Atlantic) from March 2001 to April 2002. A seasonal (bimodal) cycle was clearly observed, with maximum values in spring and summer (April-September) and minimum in winter (December-March). Shoot densities oscillated between 372 and 1014 shoots m-2, the biomass of Cymodocea nodosa between 94 and 271 g DW m-2, total vegetal biomass between 94 and 383 g DW m-2 and mean leaf lengths between 10 and 18 cm. Mean fish richness fluctuated between 0.7 and 5.3 species and total fish densities between 2.0 and 144.0 ind 100 m-2. There was a clear correlation between the cycles of C. nodosa and the associated fish population. [ABSTRACT FROM AUTHOR]
