    The role of the loquat in maintaining entomological diversity in the Conca d'Oro orchards of Sicily

    No full text
    The loquat [Eriobotryo japonica (Thumb.) Lindl.] is an allochthonous species long cultivated in Sicily. In some parts of Sicily such as the Siracusa province, the loquat is cultivated in mono-specific orchards. In other sites, like Conca d'Oro and other places near the town of Palermo, loquat is intercropped with other tree species such as citrus, apricot, peach, mulberry, walnut, Mediterranean hackberry. The loquat plays an important role in order to increase biodiversity within these orchards. The old or dead loquat trees host a variety of xylophagous insects and more in particular Coleoptera: Cerambycidae beetles Dynastidae, and Cetoniidae. Longhorn beetles, rhinoceros beetles and flower beetles are usually considered excellent indicators for woodland biodiversity and, particularly, for the wood decomposer community. However, they have never been associated to fruit orchards. Instead, in old or abandoned orchards, it is common to find live trees with dead parts or dead trees which host a rich community of decomposer insects. Today, farming changes or collapses in the urban surroundings have partly contributed to erasing this diversity. Research carried out in the past years has pinpointed that the loquat plays an important role in the preservation of different species, particularly Cerambycidae, such as: Aegosoma scabricorne, Cerambyx scopolii, Penichroa fasciata and Niphona picticornis. These species have been recorded as stable populations in many loquat orchards of the agricultural surroundings of the town of Palermo, where the presence of suitable natural environments for these beetles is rare. Some of these species are included in the red list of the sapro-xylophagous insects

    The genus Mauritanica O. Boettger, 1879 (Gastropoda Sty-lommatophora Clausiliidae) in Tunisia

    Currently, the genus Mauritanica O. Boettger, 1879 (Gastropoda Stylommatophora Clausiliidae) is widespread in north-eastern Algeria and central-northern Tunisia with six taxa. The taxonomic position of this genus has often been interpreted differently and the relationship with other similar genera, in particular with Siciliaria Vest, 1867, still remains to be clarified. In this paper, we provide a further contribution to the knowledge of Mauritanica by analyzing morphologically (shell, genitalia, and the type museum material) all the known Tunisian populations. In particular, the geographical spread and taxonomy of M. tristrami s.l. (L. Pfeiffer, 1861), M. philora s.l. (Letourneux, 1887), M. perinni polygyra (O. Boettger, 1879), and M. cossoni (Letourneux, 1887) are redefined. Mauritanica perinni zaghouanica (Letourneux, 1887) could be a valid taxon. M. tristrami zribensis n. ssp., M. tristrami nouirasaidi n. ssp. and M. philora bognanii n. ssp. are described

    Morphological and molecular analysis of the status and relationships of the land snail “Cernuella” usticensis (Calcara, 1845) (Stylommatophora: Helicoidea)

    The revision of 'Cernuella' usticensis, an helicelline hygromiid, was based on the analysis of morphological characters and on the genetic study of allozyme patterns. The morphological study demonstrates that C. usticensis can be distinguished from all the other Cernuella species by the presence of a dart sac complex with basal vaginal outgrowth, inner sac with thin walls and large lumen, and a less-developed 'dart-gun'. Analysis of allozyme polymorphisms. performed to test its relationships to other Cernuella species, namely C. virgata, C. cisalpina, C. caruanae, C. amanda and C neglecta confirms that 'C' usticensis is distinct from all those examined. Parsimony analysis of the morphological characters of all taxa included in the helicelline hygromiids (hygromiids with pedal innervation of penis) suggests that it forms a monophyletic group with Ichnusomunda based on the inner sac structure (with thin walls and large lumen). Unfortunately, material of the only species of Ichnusomunda. I. sacchii, was not available for allozyme analysis, and consequently it has not been possible to test this hypothesis genetically. Since homoplasies cannot be ruled out (inner sac with thin walls and wide lumen are known in other hygromiids), its inclusion in Ichnusomunda must await further evidence
