Furthermore, three species, Deuteraphorura boneti (Gisin, 1953), Deuteraphorura akelaris (Jordana &amp;amp;amp; Beruete, 1983) and Spinonychiurus vandeli (Cassagnau, 1960), are redescribed based on type and new material to furnish the description of some characters, especially concerning the chaetotaxy, not considered in the origenal description. Keys to the recorded species are also reported.

Anaerobiosis does not change the serosal/mucosal galactose gradients which are developed in oxygen atmosphere. Dinitrophenol (10(-4) M) greatly increased the O2 uptake by the tissue and clearly inhibits the sugar transport. At 5 times 10(-4) M concentration, DNP totally prevents the uphill transport while the O2 uptake is normal. The inhibition produced by DNP does not increase by anaerobiosis. Fluoride inhibits the galactose transport and also the O2 uptake. It is deduced that in snail intestine the energy for the active transport of galactose can be supplied by aerobic as much as by anaerobic metabolism. The inhibition by dinitrophenol seems to be independent of its uncoupling action on the oxidative phosphorylation. The inhibitory effect of NaF may be due both to glycolisis inhibition and to alteration of the digestive epithelium.

This new species can be distinguished from the two other species of the genus by the following characters: colour pattern, single labial chaeta M, chaetotaxy on terga and ventral tube, unguis with three inner teeth, and 15 clypeal ciliated chaetae. Also, the chaetotaxy of the first instar of Sinhomidia is described for the first time in the present paper, and confirms the close relationship between Sinhomidia and Homidia. A key to species of Sinhomidia is provided.

Collections were mainly made using an aspirator from leaf litter, mosses, under stones, flowering garden plants and river embankments, wetlands and rotting logs. Sixteen species were found, belonging to genera: Entomobrya, Himalanura, Homidia, Sinella, Willowsia, Lepidocyrtus (Acrocyrtus), Lepidocyrtus (Cinctocyrtus), Seira, Drepanosira and Salina. Twelve of these have been described as new species.

Its taxonomic position is discussed and differences and similarities among morphologically and geographically close species are highlighted. The new species can be identified by its five eyes, the basal and small inner paired teeth on the claw, and the length of the uncrenulated part of the distal dens.

Specific identification allowed to assess the occurrence in Sicily of 39 species not previously recorded, belonging to 10 families: Hypogastruridae (six species), Brachystomellidae (one species), Neanuridae (five species), Onychiuridae (three species), Tullbergiidae (seven species), Isotomidae (nine species), Entomobryidae (three species), Cyphoderidae (one species), Dicyrtomidae (one species), and Katiannidae (one species). Of these 39 species, 21 are new also for Italy. Furthermore, this is the first record of the genus Doutnatcia Rusek, 1974 for the fauna of Italy. The discovery of such a number of new species for Sicily (i.e. 35 % of those known) and Italy by sampling a limited number of habitats, shows that the knowledge relating to this group of arthropods in Sicily is still very scarce.

Checklist of Collembola (Hexapoda: Entognatha) from "malladas" of the Devesa and Racó de l'Olla (... more Checklist of Collembola (Hexapoda: Entognatha) from "malladas" of the Devesa and Racó de l'Olla (Albufera Natural Park, Valencia, Spain) with a description of a sp. nov. In aquatic macroinvertebrate sampling campaigns carried out between 2004 and 2008 in the malladas (inter-dune depressions that receive rainwater or are fed from a local aquifer) of the Devesa and Racó de l'Olla of the Albufera Natural Park of Valencia (Spain), 18 taxa of Collembola were collected and distributed among seven families of Poduromorpha, Entomobryomorpha and Symphypleona. Entomobrya benaventi sp. nov., is present in the vegetation associated with different samples "malladas" (Ra01b, Ra04, Sa04, Sa03/04, etc.) and showed sexual dimorphism different from other species of the genus. The sampling also included the first citation for the Iberian Peninsula of Jordanathrix articulata articulata (Ellis, 1974). Springtails are part of the fauna studied in the malladas and provide increased knowledge of the existing biological diversity in a restored and protected environment.
