The unexpected complexity of the Embioptera (Insecta) fauna of the Tuscan Archipelago (Italy), with the disambiguation of two species of Haploembia Verhoeff, 1904 and the description of a new species of Embia Latreille, 1825
No full textVery little is known about the Embioptera of the Tuscan Archipelago, and no specific study has been published from there on this insect order. The study of literature and new material has allowed us to identify the presence of four species of Embioptera in the Tuscan Archipelago: Haploembia solieri (Rambur, 1842), Haploembia tarsalis Ross, 1940 (which was reported for the first time in Italy), Embia ramburi Rimsky-Korsakov, 1905 and E. ilvana n. sp., which is described here. As regards the species of the genus Haploembia Verhoeff, 1904, some bio-ethological aspects and the global distribution of the two species present in the archipelago are discusse
New and Interesting Records of Coleoptera from Northeastern Italy and Slovenia (Alexiidae, Buprestidae, Carabidae, Cerambycidae, Ciidae, Curculionidae, Mordellidae, Silvanidae)
No full textIn the present work, new faunal reports for northeastern Italy and Slovenia are provided: Stomis philospelaeusMonzini, 2018 (Carabidae) is recorded in a new locality; Anthaxia senicula (Schrank, 1789) (Buprestidae) and Hoshihananomia gacognei (Mulsant, 1852) (Mordellidae) are recorded in the Veneto region for the first time. Acallocrates colonnelliiBahr, 2003 (Curculionidae) is newly recorded from Italy while Sphaerosoma pilosum (Panzer, 1793) (Alexiidae) and Mordellistena michalki Ermisch, 1956 (Mordellidae) are new additions to the Slovenian fauna. Furthermore, new or additional data on the exotic Cis chinensis Lawrence, 1991 (Ciidae), Chydarteres striatus (Fabricius, 1787), Cordylomera spinicornis (Fabricius, 1775), Neoplocaederus viridescens (Atkinson, 1953) (Cerambycidae) and Telephanus atricapillus Erichson, 1846 (Silvanidae) are given
A new genus and species of anophthalmous Otiorhynchini from Greece, with a new synonymy and new combinations (Coleoptera: Curculionidae, Entiminae)
No full textA new genus of Entiminae, an endogean weevil of the tribe Otiorhynchini, Giavarhynchus Bellò, Osella & Ruzzier, gen. n., and its type species Giavarhynchus amicorum Bellò, Osella & Ruzzier, sp. n. are described. The new taxon is readily distinguished from all other members of the tribe due to the unique combination of lack of eyes, elongate rostrum with a ventral transverse furrow and excised lateral margins located at apical third, punctation of pronotum of two distinct sizes arranged in a distinctive pattern, interval 7 of elytra protruding from base of pronotum and crenulate basally, metafemora bearing a spine-like tooth much larger than that of pro- and mesofemora, female tibiae granulate on inner margin, bisinuous mesotibiae. The following synonymy is proposed: Nematocerus Reiche, 1849 (= Cyrtozemia Pascoe, 1872, syn. n.; = Holcorhinosoma Voss, 1939, syn. n.). New combinations are: Nematocerus cognatus (Marshall, 1916), comb. n.; Nematocerus dispar (Pascoe, 1872), comb. n.; Nematocerus pilipes (Morimoto, 2015), comb. n., all from Cyrtozemia; Nematocerus subtuberculatus (Voss, 1939), comb. n. from Holcorhinosoma. New tribal placement is: Pseudocratopus Hustache, 1921 from Otiorhynchini to Peritelini. New subgeneric placement is that of Otiorhynchus deceptorius Białooki, Germann & Pelletier, 2017 and of Otiorhynchus incisirostris Białooki, Germann & Pelletier, 2017 from Otiorhynchus (Lixorrhynchus) Reitter, 1914 to Otiorhynchus (Aranihus) Reitter, 1912

No full textThe Buprestidae (Coleoptera, Buprestoidea) of the Tuscan Archipelago (Italy)
Full text linkBackground
Buprestidae is a group of beetles of important conservation and phytosanitary value that is poorly studied in the Tuscan Archipelago and the limited faunistic knowledge available refers to a few scant historical records.
New information
The present contribution increments the species documented in the Archipelago from 27 to 51, providing more than 300 georeferenced occurrence records, derived from both direct field research and citizen science via iNaturalist. Of particular importance is the discovery of Eurythyrea quercus on Isola d'Elba, an uncommon and localised species currently critically endangered
In search of the most mysterious orthopteran of Europe: the Reed cricket Natula averni (Orthoptera: Gryllidae).
Full text linkIn the last few years a lot of new information has become available on Natula
averni. As the common name we propose Reed cricket, because the species was found almost exclusively in reed beds. Recent findings show that this species is more abundant than previously thought. The species can easily be found with knowledge of distribution, habitat and song, all described in this publication. Nevertheless a lot of questions remain about the taxonomy. We hope that information gathered after this publication will help us to reveal the proper identity of reed crickets in Europe
Updated distribution of the invasive Megachile sculpturalis (Hymenoptera: Megachilidae) in Italy and its first record on a Mediterranean island
Full text linkMegachile sculpturalis (Smith, 1853) (Hymenoptera: Megachilidae) is an invasive solitary bee that is rapidly spreading all over Europe. The present study aims to update the distribution of this species in Italy. The research led to the collection of 177 records, obtained through bibliographic research and data-mining from websites, blogs and social networks. We here present the first record of M. sculpturalis on a Mediterranean island and discuss its possible effect on the native ecosystem. Given the particular discovery of M. sculpturalis on Elba Island (Tuscany), we suggest possible monitoring, containment and possible eradication measures of the species
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
