| Specimens of Spadella cephaloptera from Tenerife, Gran Canaria and Gomera (Canary Islands) were compared biometrically in regards to morphometric and meristic characters. Variation exists among the populations on the islands as well as between the islands. The populations on Gomera seem more distinct from the populations on Tenerife and Gran Canaria than the two latter are mutually. An apparent decline in the number of adults occurs in July, which is related to a decrease in the number of eggs. A shortage of food can explain the reduced fecundity of the specimens. S. cephaloptera prefers habitats protected from the influence of waves. |

| Six novel polymorphic microsatellite markers were isolated from enriched libraries in Myrica faya Ait., recently renamed Morella faya , (fayatree, firetree, or firebush) in order to examine the genetic diversity in natural populations. Also, test cross-specific amplification and genetic diversity in Myrica rivas-martinezii, which is endemic on the Canary islands. Microsatellite loci were screened in 225 individuals of both species from different islands of the Canarian archipelago. All markers were successfully amplified from both Myrica species, with an average number of 6.5 and 9.3 alleles per locus in M. rivas-martinezii and M. faya , respectively. There was no evidence for linkage disequilibrium between loci, and the probability of null... |

| The decapods Eualus lebourae, Processa modica carolii, Palaemon xiphias, Philocheras bispinosus, and Inachus phalangium are recorded from the coasts of Madeira for the first time. The decapods Hippolyte garciarasoi, Hippolyte varians, Eualus lebourae, Processa parva, Processa modica carolii, Processa robusta, Palaemonella atlantica, Periclimenes wirtzi, Philocheras bispinosus, and Philocheras fasciatus, are recorded from the coasts of the Canary Islands for the first time. Eualus occultus, Processa parva and Processa modica carolii are recorded from the Cape Verde Islands for the first time. Processa parva is also recorded for the Azores for the first time. For Eualus occultus, Hippolyte garciarasoi, Processa modica carolii, Periclimenes wirtzi and... |

| Seven species of Tubificidae are recorded from the Canary Islands, viz. Heterodrilus amplus n. sp., Coralliodrilus leviatriatus Erséus, 1979, Limnodriloides agnes Hrabĕ, 1967, L. janstocki n. sp., Aktedrilus cuneus Erséus, 1984, A. parvithecatus (Erséus, 1978), and Tubifex tubifex (Müller, 1774); the two latter taxa are reported also from the Cabo Verde Islands. All taxa except T. tubifex are marine and there is no evidence of endemism in the freshwater oligochaete fauna of these islands. Heterodritus amplus has short, spindle-shaped, heavily muscular atria; they are morphologically unique within the genus. Limnodriloides janstocki has modified spermathecal setae; it is distinguished from similar species by its long atrial ducts and deep, elaborate... |

| Lovenula (Neolovenula) alluaudi is widespread on Lanzarote, where it occurred at 22 of the 105 stations. On Fuerteventura it was found at only 2 of the 53 stations, both in the extreme northwest part of the island. It was also found in a reservoir on the south side of the small island of Alegranza. Samples collected at several hundred stations in the other Canary Islands failed to yield a single calanoid, supporting the belief that the eastern islands are fragments of the African continent that drifted to deeper waters. Males outnumbered females in about 2/3 of the samples, often heavily. |

| The catch from bottom longline stations sampled from a series of research cruises around Lanzarote and Fuerteventura (Canary Islands, NE Atlantic) was analysed in terms of fish distribution, density and diversity. The distribution of the number of species and individuals caught per station appeared to fit well the Poisson and Exponential distribution function, respectively. In particular, the parameter of the Poisson's distribution appeared to provide an index of the point (at station scale) diversity, and its confidence interval, allowing for statistical comparisons. The relationships between point diversity, the alpha diversity (in the depth strata) and the beta diversity (along the depth gradient) were investigated. Around the islands, the density and... |

| The West Palaearctic species of the genera Gildoria Hedqvist, 1974, and Platyspathius Viereck, 1911 (Braconidae: Doryctinae) are revised. Five new species are described and illustrated: Gildoria elongata spec. nov. from Canary Islands, G. gijswijti spec. nov. from France, G. iberica spec. nov. from Spain, G. striata spec. nov. from Morocco and Platyspathius europaeus spec. nov. from France and Italy. The genus Gildoria is re-instated, Gildoria anthaxiae (Belokobylskij, 1983), G. grandis (Fahringer, 1930), G. planus (Ratzeburg, 1848), G. similis ( Bouc˘ek, 1955) and G. titubata (Papp, 1985) are new combinations, and Dendrosotinus ilanotensisC ˘ apek, 1992, is synonymized with Gildoria titubata (Papp, 1985). Doryctes lenticularis Granger, 1949, is designated... |
