    A new species of the genus Milax Ellis, 1926 (Gastropoda Pulmonata Milacidae) from Lampedusa Island (Sicilian Channel, Italy)

    ABSTRACT
    Milax lopadusanus n. sp. (Gastropoda Pulmonata Milacidae) is described from Lampedusa Island, the biggest of the islands of the Pelagie Archipelago (Sicilian Channel, Italy). The new species is characterized by: greyish-brown body, with distinct yellowish keel; conical, smooth stimulator, with a raised crest along one side and spermatophore characterized by conic anterior part, covered on one side by bifurcated spines with the two apexes thorny; posterior part cylindrical, covered by smaller and most dense spines on all sides. Additional faunistic, biological and taxonomical notes are provided.

    Chiloneus hoffmanni (Gonzáles, 1970) (Coleoptera Curculionidae) new to Italy, with a checklist of the species of the genus and ecological notes

    ABSTRACT
    Chiloneus hoffmanni (González, 1970) (Coleoptera Curculionidae) thus far considered a Maltese endemic, is here recorded for the first time from Lampedusa island (Italy). Several adults of this species and of C. solarii Pesarini, 1970 were found feeding on leaves of Charybdis pancration (Asparagaceae). These observations constitute the first data on the ecology of these species. An updated checklist of Chiloneus Schoenherr, 1842 is also provided.

    Update to the status of Pantala flavescens (Fabricius, 1798) and Trithemis kirbyi Selys, 1891 for Italy and Central Mediterranean basin (Odonata Libellulidae)

    ABSTRACT
    An overview of the records of Pantala flavescens and Trithemis kirbyi for the Sicilian Channel islands and mainland Sicily, with comments on their possible status in this area, is provided. In light of the number of observed individuals, P. flavescens is likely to be regular in the studied area, with up to 30 individuals recorded per year since autumn 2012. Trithemis kirbyi, conversely, is only known from few scattered records, so that its status in the area remains to be elucidated. No evidence of reproductive behaviour nor of actual breeding in this area was hitherto found for any of the two species.

    A quantitative morphological geographical study from a widely distributed raptor: the Lesser Kestrel Falco naumanni Fleischer, 1818 (Falconiformes Falconidae)
    Proceedings of the 2nd International Congress “Speciation and Taxonomy”, May 16th-18th 2014, Cefalù-Castelbuono (Italy)

    ABSTRACT
    Lesser Kestrel Falco naumanni Fleischer, 1818 (Falconiformes Falconidae) is considered a monotypic species. F. naumanni pekinensis Swinhoe, 1870 was described from Beijing, China. Although considered valid for most of the 20th century, some authors treated F. naumanni pekinensis as a synonym of F. naumanni naumanni, and subsequent authors have since regarded “pekinensis” as an invalid taxon. Recent field observations in Asia and Europe and museum studies have confirmed diagnosable differences in (fresh) adult males. Comparing morphology between nominate “naumanni ” and “pekinensis”, with the latter invariably showing more extensive grey on the wing coverts and darker and more saturated colours on both the underparts and upperparts, with all grey areas, including the hood, being a darker, deeper lead-grey. Females often have more extensive dark markings and a better-defined dark eye-line but apparently are indistinguishable in most cases. This study aims to re-evaluate F. naumanni pekinensis and to discuss geographic variation in the subspecies in a widely distributed raptor.

    Morphological differences between two subspecies of Spotted Flycatcher Muscicapa striata (Pallas, 1764) (Passeriformes Muscicapidae)
    Proceedings of the 2nd International Congress “Speciation and Taxonomy”, May 16th-18th 2014, Cefalù-Castelbuono (Italy)

    ABSTRACT
    Four subspecies of Spotted Flycatcher (Muscicapa striata Pallas, 1764) (Passeriformes Muscicapidae) are usually recognized within the Western Palaearctic. We carefully analysed two of these in order to determine and quantify their morphological differences: M. striata striata (inhabiting most of continental Europe east to the Ural mountains and a small portion of north-western Africa) and M. striata tyrrhenica Schiebel, 1910 (breeding on the Tyrrhenian islands of Corsica, Sardinia and the Tuscan Archipelago). We examined total of 58 Spotted Flycatcher specimens from Italian museums (of which 18 M. striata tyrrhenica) and obtained data about morphological features such as wing point, length and formula, and bill length, width and depth; furthermore, we investigated plumage colour using a spectrometer. Biometric measurements and an analysis of plumage streaking confirmed the presence of important differences between the two taxa; the colorimetric analysis did not produce the expected results, although it had some interesting implications concerning the preservation of museum specimens and their use in studies of plumage colour.

    Annotated checklist of the dragonflies (Insecta Odonata) of the islands of the Sicilian Channel, including the first records of Sympetrum sinaiticum Dumont, 1977 and Pantala flavescens (Fabricius, 1798) for Italy

    ABSTRACT
    In this paper we report data on the historical and recent status of all dragonfly species (Insecta, Odonata) recorded for the Sicilian Channel islands: the Pelagie islands and Pantelleria, politically belonging to Italy, and Maltese Archipelago islands. The number of species known for the former group of islands raises from 7 to 20. Of these, 2 are new for the Italian fauna, namely the Desert Darter Sympetrum sinaiticum, noticed through likely sightings starting from 2010 on Lampedusa, and confirmed through voucher specimens collected in April 2012, and the Wandering Glider Pantala flavescens, first noticed in October 2012 on Lampedusa and Linosa; while Calopteryx sp. cf. haemorrhoidalis, Ischnura genei, Aeshna mixta, Orthetrum nitidinerve, Orthetrum coerulescens anceps, Crocothemis erythraea, Sympetrum striolatum, S. meridionale, Brachythemis impartita, Trithemis annulata and T. kirbyi, already known for Italy, are new for the Italian islands of the Sicilian channel. The Maltese fauna includes at present 18 recorded species; the previously reported Trithemis arteriosa is to be deleted from the list, since the concerned specimen upon re-examination proved to be T. annulata.

    Annotated checklist of the birds from Pantelleria Island (Sicilian Channel, Italy): a summary of the most relevant data, with new species for the site and for Italy

    ABSTRACT
    The updated annoted checklist of all the bird species recorded at Pantelleria island (Trapani, Sicily, Sicilian Channel) up to May 2012 along with data on the status of the birds are reported. The total number of species recorded is 261, 43 of which are new for the islands compared to the previous checklist. During our study, very rare species for the Italian fauna were recorded including Semi-collared Flycatcher, Citrine Wagtail, Steppe Eagle, Daurian Shrike, Desert Wheatear, Trumpeter Finch, Black Wheatear and Rufous Bush-Chat. Detailed data and available documentation are reported for the most relevant records.
