The morphology of the first zoea stage of Chaceon affinis is described and illustrated in detail for the first time. Morphological comparison with the corresponding stage of other known species of Geryonidae allowed the differentiation between the genera Chaceon and Geryon, although it was impossible to distinguish among species of Chaceon using larval morphology. Thus, geryonid larvae collected in the plankton of Gran Canaria Island, NE Atlantic, during the years 2005 and 2006, could only be identified as Chaceon spp. The temporal distribution of larval abundance suggested that main hatching periods of Chaceon spp. occur in spring and summer. These results are useful to better understand the reproductive strategies of these deep-water crabs, which in turn will be useful for future fishery management of this resource of increasing interest in the Canary Islands.

A monitoring programme was established to collect plankton samples and information of environmental variables over the shelf off the island of Gran Canaria during 2005 and 2006. It produced a detailed snapshot of the composition and seasonal assemblages of the decapod larvae community in this locality, in the subtropical waters of the Canary Islands (NE Atlantic), where information about crustacean phenology has been poorly studied. The larval community was mainly composed of benthic taxa, but the contribution of pelagic taxa was also significant. Infraorders Anomura (33.4%) and Caridea (32.8%) accounted for more than half the total collected larvae. High diversity, relatively low larval abundance throughout the year and weak seasonality characterized the annual cycle. However, in relation to the temporal dynamics of temperature, two distinct larval assemblages (cold and warm) were identified that correspond to periods of mixing and stratification of the water column. The results also indicate that larval release times and durations in the subtropical waters are earlier and longer than at other higher latitudes in the NE Atlantic. We detected the presence of larvae of six species that have not yet been reported from the Canary Islands (Pandalina brevirostris, Processa edulis, Necallianasa truncata, Parapenaeus longirostris, Crangon crangon, Nematopagurus longicornis). Finally, this study provides a baseline for future comparisons with respect to fishery pressure and climate variability in this subtropical region.

The morphology of the second zoeal stage of Grapsus adscensionis, hatched from ovigerous specimens collected in the supralittoral zone of Taliarte Harbour, Gran Canaria (Canary Islands, NE Atlantic), is described and illustrated in detail for the first time. The comparison of its larval morphology with those of other species of Grapsidae provides information for the characterization of the zoeal morphology of grapsids, with implications in the phylogenetic relationships within the family, as well as an aid in identification of plankton samples.

The genus Atomopria Kieffer, 1911 currently includes two only described species: A. fulvicornis Kieffer, 1911, from north-western Italy (Liguria) and A. rufithorax Kieffer, 1911, from Tunisia (Tunis). The following ten new species are described from North Africa and Canary Islands: A. helenae n. sp. (Algeria, Kabylia), A. giachinoi n. sp. (Algeria, Kabylia), A. lisae n. sp. (Algeria, Kabylia), A. olmii n. sp. (Canary Islands, Gran Canaria), A. ortegae n. sp. (Canary Islands, Tenerife), A. boffai n. sp. (Canary Islands, Tenerife), A. cavazzutii n. sp. (Canary Islands, Tenerife), A. longicornis n. sp. (Canary Islands, Tenerife), A. paglianoi n. sp. (Canary Islands, Tenerife), A. scaramozzinoi n. sp. (Canary Islands, Tenerife). Diagnostic morphological features of representatives of this genus are described; male genitalia of some species are illustrated for the first time. The synonymy of the genus Atomopria with Basalys Westwood, 1832 is also hypothesized, but not proposed in this contribution. A key for identification of all species is provided, both for females and males. Finally, some taxonomic and biogeographic questions are briefly debated.

Hemicycla (Adiverticula) diegoi n. sp. from the westernmost part of the Teno massif above the Lighthouse at Punta de Teno, Tenerife, Canary Islands is described and compared to conchologically and anatomically similar species in the genus Hemicycla Swainson, 1840. The validity of the new species is corroborated by a phylogenetic analysis including several congeneric species, interand intraspecific genetic distances and a morphometric comparison by means of a discriminant function analysis. Hemicycla cf. paivanopsis (Mabille, 1882) and Hemicycla quadricincta quadricincta (Morelet, 1864) from La Gomera and Hemicycla berkeleii (R. T. Lowe, 1861) from Gran Canaria are tentatively placed in Hemicycla s. str. on the basis of a phylogenetic analysis. Furthermore, Eobania vermiculata (O. F. Müller, 1774) is reported as an introduced species in Gran Canaria for the first time.

Island ecosystems are particularly vulnerable to the introduction of exotic species that can have an impact on local fauna and flora. Here, the carpenter bee Xylocopa pubescens is reported in Gran Canaria (Canary Islands, Spain) for the first time. This species is native to North Africa and the Near East and shows a rapid dispersion across the city of Las Palmas de Gran Canaria, together with a single record in the southernmost tip of the island. Different hypotheses about its arrival to the island are discussed.

Abstract.Oral improvisation in verse is one of the most interesting manifestations of intangible heritage of peoples. At the University of Las Palmas de Gran Canaria, in the Peritia et Doctrina program, I have had the opportunity to work with the poetic strophes in which this tradition is manifested in the Canary Islands. I searched thereby stimulate creativity and memory of older people who find, perhaps for the first time, with the creative nature of poetry using, by example, a strophe of the sixteenth century, that, however, it has a bright future in front.Key Words: poetry, oral improvisation in verse, older people, creativity, memoryResumen.La improvisación oral en verso es una de las manifestaciones más interesantes del patrimonio inmaterial de los pueblos.

Seven individuals ofC.coeruleawere collected in the most humid branch of an abandoned water mine in Gran Canaria (Canary Islands). Due to its character of generalist predator, it should be considered a threat for the endemic subterranean fauna.
