Abstract

Squamapion gardinii n. sp. from Italy, France and Spain (♂♀; type locality: Italy: Liguria: Genoa Province: Genova-Quinto al Mare: Rio San Pietro), associated with Thymus vulgaris L., is described. Squamapion solariorum (Wagner, 1908) n. stat., upgraded to species rank from subspecies of Squamapion consors (Desbrochers des Loges, 1875), is redescribed (holotype ♀ examined). New chorological records for Squamapion minutissimum (Rosenhauer, 1856) and Squamapion serpyllicola (Wencker, 1864) are also given; the latter species is recorded for the first time from Italy and Romania. A provisional key is provided to the species of Squamapion, related to Squamapion atomarium (Kirby, 1808), present in the Mediterranean region.

Adults are on the host plant from April to December with the peak of attendance between June and September (especially in September). It prefers meadows, roadsides and slopes, in arid and xeric habitats, with calcareous or siliceous soils, from hills (250 m a.s.l.) to mountains (2,450 m a.s.l.) (Giusto 2021b . In Italy it is recorded from northern and central peninsula (with the exclusion of Aosta Valley and Latium) and Sicily . ...

An annotated catalogue of Coleoptera Curculionoidea of “Monte Grappa” Biosphere Reserve is presented. The 528 species surveyed, divided into 7 families and 283 genera and subgenera, include the 265 species already known, plus the 263 are reported for the first time for the area. Faunistic, chorological and ecological information is given for all the species together with 1.015 illustrations of distinctive species, collecting techniques and selected habitats. In addition the database of 20.000 specimens collected can be found at: doi.org/10.5281/zenodo.7497691

L’esigenza di studiare la fauna dei Coleotteri delle 10 Riserve Naturali dello Stato gestite dal Reparto Carabinieri Biodiversità di Belluno, al fine di approfondirne le conoscenze, ha messo in evidenza la necessità di disporre di uno strumento “agile” per la determinazione delle numerose famiglie di Coleotteri della nostra fauna. Da questa necessità è nata l’iniziale idea di sviluppare una chiave dicotomica ricca di immagini e schemi di dettaglio, che in corso d’opera è stata poi arricchita anche dalle tavole anatomiche e dal glossario. A completamento del progetto, è sembrato utile allegare un catalogo di tutte le 13047 specie di Coleotteri ad oggi segnalate per il nostro Paese, oltre ad una sintetica descrizione delle famiglie esaminate, corredata da note bio-ecologiche e dall’indicazione di alcuni strumenti bibliografici utili per la determinazione a livello specifico degli esemplari in studio. Quest’opera rappresenta principalmente uno strumento adatto a suddividere i Coleotteri della fauna d’Italia in un totale di 148 famiglie, permettendo talvolta di discriminare tra generi o specie diverse, soprattutto nel caso di famiglie per le quali la fauna italiana risulta composta da poche specie. Tutte le informazioni e i dati che sono qui riportati (caratteri anatomici, note biologiche ed ecologiche, numero di specie ...) fanno riferimento esclusivamente alle specie di Coleotteri presenti in Italia, con aggiornamento al mese di novembre 2021. La struttura di questa chiave dicotomica si basa sullo studio e la rielaborazione, con adattamento per le specie della fauna italiana, di numerosi lavori scientifici e chiavi dicotomiche che vengono riportati in bibliografia, oltre all’analisi diretta dei caratteri diagnostici, effettuata sul materiale della collezione entomologica del Reparto Carabinieri Biodiversità di Belluno e delle collezioni private degli autori. The need to study the Beetle fauna of the 10 State Natural Reserves managed by the Reparto Carabinieri Biodiversità of Belluno, in order to increase their knowledge, has highlighted the need to have a "smart" tool for determining the numerous families of Beetles of our fauna. From this need, the initial idea of developing a dichotomous key, rich in images and detailed schemes, was born. The key was then enriched with anatomical tables and a glossary. To complete the project, it seemed useful to add a catalogue of all 13047 species of Beetles reported to date for our Country, as well as a brief description of the examined families, with bio-ecological notes and a list of some bibliographic tools to be used for the determination of the specimens under study at the specific level. This work mainly represents a suitable tool for dividing the Beetles of the Italian fauna into a total of 148 families, sometimes allowing to distinguish different genera or species, especially in the case of families composed of a few italian species. Information and data here given (anatomical characters, biological and ecological notes, number of species ...) refer exclusively to the species of Coleoptera recorded for Italy, updated on November 2021. The structure of this dichotomous key is based on the study and re-elaboration of numerous scientific works and dichotomous keys, that are listed in bibliography, with adaptation for the species of the Italian fauna, in addition to the direct analysis of the diagnostic characters of the specimens of the entomological collection of the Reparto Carabinieri Biodiversità of Belluno and of the authors' private collections.
