Notes on the status and the current spread of Viburnum tinus L. (Viburnaceae) in Sicily (Italy)

The authors carried out a multi-disciplinary research in order to clarify the native status of Viburnum tinus in Sicily and update the knowledge about its current regional distribution. With this purpose, a large amount of scientific papers on forestry, botany and palaeo- and archaeobotany was consulted; more useful data issued from papers focused on local historical gardens, from archives and from herbarium specimens. The available data suggest that most of the extant nuclei may issue from the recent colonization of plants introduced just few centuries ago. Although the status of the stands found in some warm and humid sites in the surroundings of the city of Palermo and on the Sicani Mountain Range remains uncertain, with no doubt the majority of the other populations, including the seven new ones mentioned for the first time in this paper, issue from the recent spread of this species in several coastal and inland areas, a process which has been facilitated by its efficient seed dispersal strategy and its massive use as an ornamental plant in the green areas of the island

New data on Protaetia (Potosia) Opaca (Coleoptera Cetoniidae) from Pantelleria island (Sicilian Channel, Italy)

Gli autori segnalano la presenza di Protaetia (Potosia) opaca (Fabricius 1787) nell\u2019isola di Pantelleria (Canale di Sicilia, Mediterraneo centrale, Italia). Essi inoltre forniscono ulteriori osservazioni tassonomiche, biologiche e sulla distrubuzione di questa specie.Protaetia (Potosia) opaca (Fabricius 1787) (Coleoptera Scarabaeoidea Cetoniidae) is here being reported for the first time from the island of Pantelleria (Sicilian Channel, Central Mediterranean Sea, Italy). Taxonomic, distribution and biological data on this species are presented

PLUMBAGO AURICULATA LAM. (Plumbaginaceae) IN SICILIA OCCIDENTALE: NUOVI DATI SULLA SUA DIFFUSIONE COME ESOTICA CASUALE

Plumbago auriculata Lam. (Plumbaginaceae) in western Sicily: new data on its spread as casual alien. In questa nota si fornisce un quadro aggiornato sui casi di naturalizzazione di Plumbago auriculata Lam. (Plumbaginaceae) nella Sicilia occidentale e sul suo status invasivo a livello nazionale ed internazionale. Questa xenofita viene segnalata per la prima volta in diverse aree delle province di Agrigento, Palermo e Trapani, dopo essere stata segnalata per la prima volta presso l'isola di Linosa, nell'arcipelago delle Pelagie

Primi segnali di spontaneizzazione di Schinus molle L. (Anacardiaceae) in Sicilia.

Si riportano i primi casi di naturalizzazione di Schinus molle L. (Anacardiaceae) osservati in Sicilia

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

Pachydema lopadusanorum n.sp. (Coleoptera Melolonthidae) from Lampedusa Island (Sicily Channel, Central Metditerranean Sea, Italy)

In this paper the populations of Pachydema Castelnau, 1832 (Coleoptera Melolonthidae) living in Lampedusa Island (Sicily Channel, Central Mediterranean Sea, Italy), so far attributed to P. hirticollis (Fabricius, 1787) of North Africa, are examined. The comparison of the main morphological characters between these two populations allowed to attribute those of Lampedusa to a new species that is described in the present work. Faunistic and biological observations on these species are provided
