In this contribution, new data concerning the Italian distribution of alien vascular flora are presented. It includes new records, exclusions, confirmations, and status changes for Italy or for Italian administrative regions for taxa in the genera Acer, Amaranthus, Araujia, Aubrieta, Avena, Bidens, Calycanthus, Celtis, Elaeagnus, Eragrostis, Euonymus, Fallopia, Ficus, Hedera, Lantana, Ligustrum, Ludwigia, Morus, Oenothera, Opuntia, Oxalis, Parkinsonia, Paspalum, Paulownia, Platycladus, Pleuropterus, Rumex, Salvia, Senecio, Setaria, Syagrus, Tradescantia, Trifolium and Yucca. Furthermore, a new combination in the genus Vicia is proposed.

New genera, species and records of Afrotropical Phaneropterinae (Orthoptera, Tettigoniidae) preserved at the Royal Belgian Institute of Natural Scien…
2017
The results of the study of the rich material of Orthoptera Phaneropterinae at the Royal Belgian Institute of Natural Sciences, Bruxelles, are reported. The following new taxa are described: Dithela longicaudata n. sp. from the Democratic Republic of Congo, Terpnistriella bredoi n. gen. n. sp. from the Democratic Republic of Congo, Mimoscudderia paulyi n. sp. from the Madagascar, Pseudogoetia constanti n. gen. n. sp. from the Democratic Republic of Congo (including a table listing differences with related genera), and Materuana abyssinica n. sp. from the Ethiopia. Some taxonomic and distributional data about the following species are also reported: Melidia claudiae Massa, 2015, Symmetrokars…
Review of the African genera Arantia Stål and Goetia Karsch (Orthoptera: Tettigoniidae: Phaneropterinae)
2017
The genus Arantia is reviewed, the distribution and distinguishing characters given. The three species of Goetia are assigned as subgenus to Arantia. Arantia gestri Griffini is transferred to this new subgenus and synonymized with G. dimidiata Bolívar. Other species synonymized are: A. accrana Karsch with A. rectifolia Brunner von Wattenwyl; A. gabunensis Brunner von Wattenwyl with A. regina Karsch; A. mammisignum Karsch and A. tigrina Bolívar with A. excelsior Karsch; A. ugandana Rehn is synonymized with A. fasciata (Walker). 6 species from Tropical Africa are newly described: A. (Arantia) quinquemaculata n. sp., A. (Arantia) ivoriana n. sp., A. (Euarantia) tanzanica n. sp., A. (Euarantia)…
Hantavirus infections in fluctuating host populations: the role of maternal antibodies.
2010
Infected females may transfer maternal antibodies (MatAbs) to their offspring, which may then be transiently protected against infections the mother has encountered. However, the role of maternal protection in infectious disease dynamics in wildlife has largely been neglected. Here, we investigate the effects of Puumala hantavirus (PUUV)-specific MatAbs on PUUV dynamics, using 7 years' data from a cyclic bank vole population in Finland. For the first time to our knowledge, we partition seropositivity data from a natural population into separate dynamic patterns for MatAbs and infection. The likelihood of young of the year carrying PUUV-specific MatAbs during the breeding season correlated p…
Advantage of rare infanticide strategies in an invasion experiment of behavioural polymorphism
2012
Killing conspecific infants (infanticide) is among the most puzzling phenomena in nature. Stable polymorphism in such behaviour could be maintained by negative frequency-dependent selection (benefit of rare types). However, it is currently unknown whether there is genetic polymorphism in infanticidal behaviour or whether infanticide may have any fitness advantages when rare. Here we show genetic polymorphism in non-parental infanticide. Our novel invasion experiment confirms negative frequency-dependent selection in wild bank vole populations, where resource benefits allow an infanticidal strategy to invade a population of non-infanticidal individuals. The results show that infanticidal beh…
On some interesting African katydids (Orthoptera Tettigoniidae)
2016
Results of the study of specimens collected in Africa and preserved in different European collections and museums are reported and extensively illustrated. The tribe Preussiini Karsch, 1890 is resurrected for the genera Preussia Karsch, 1890, Enochletica Karsch, 1896 and Weissenbornia Karsch, 1888. The following three new species are described: Eurycorypha ndokiensis n. sp., Eurycorypha feai n. sp. and Eurycorypha kenyensis n. sp. Rhacocleis dernensis Salfi, 1926 is confirmed in its original genus, Conocephalus algerinorum Massa, 1999 is moved into the subgenus Anisoptera. In addition, new diagnostic characters or distributional data for Horatosphaga crosskeyi Ragge, 1960, Horatosphaga soma…
New taxa of Orthoptera (Insecta Tettigoniidae Phaneropterinae) from Madagascar.
2017
The author reports the results of a study on Orthoptera collected in Madagascar and preserved in two European Natural History museums. He describes Symmetroraggea depravata n. sp., Parapyrrhicia longipodex n. sp., Madagascarantia bartolozzii n. gen. n. sp., Mimoscudderia spinicercata n. sp. In addition, he lists new records or unknown taxonomical characters of Xenodus nobilis Carl, 1914 and Parapyrrhicia virilis Carl, 1914.
New records of phytoseiid mites from Italy, with description of a new species and a redescription of other two (Parasitiformes, Phytoseiidae)
2020
The Italian phytoseiid fauna consists of 91 valid species. Eighteen of them were described as new species from materials collected in various Italian localities. In the present paper we report nine new records from the Italian fauna and describe the new species, Neoseiulus mediterraneus belonging to the subfamily Amblyseiinae. Complementary descriptions of two rare species, namely: Typhlodromus (Anthoseius) singularis and Typhlodromus (Typhlodromus) knisleyi, were also added.
