I Ropaloceri di otto Zone Speciali di Conservazione-Zone di Protezione Speciale della Provincia di Siena (Toscana Meridionale) (Lepidoptera, Papilionoidea)

A summary is provided of the knowledge of the rhopaloceran fauna of eight Special Areas Conservation (SAC) - Special Areas Protection (SAP) of the province of Siena (IT5190001 Castelvecchio; IT5190004 Crete di Camposodo e Crete di Leonina; IT5190005 Monte Oliveto Maggiore e Crete di Asciano; IT5190007 Basso Merse; IT5190010 Lucciolabella; IT5190011 Crete dell’Orcia e del Formone; IT5190013 Foreste del Siele e del Pigelleto di Piancastagnaio; IT5190014 Ripa d’Orcia) based on scientific publications and unpublished data. 96 species are reported for the 8 SAC-SAPs. The Crete dell’Orcia e del Formone and Castelvecchio with 75 species are distinguished by the presence of rich populations, the Crete di Camposodo e Crete di Leonina with 40 species are distinguished by the presence of poor populations. The most significant species for conservation value and biogeographical interest are: Zerynthia cassandra Geyer, [1828], endemic to Italy; Gegenes nostradamus (Fabricius, 1793), whose distribution, phenology and larval ecology are poorly known; Reverdinus lavatherae (Esper, [1783]), Pyrgus sidae (Esper, [1784]), Satyrium w-album (Knoch, 1782), Cupido argiades (Pallas, 1771), Cupido osiris (Meigen, 1829), Brenthis hecate ([Denis & Schiffermüller], 1775) and Argynnis pandora ([Denis & Schiffermüller], 1775), uncommon, rare, localized or decreasing in Italy or Tuscany; Maculinea arion (Linné, 1758), a species in decline in Europe. Knowledge for some SAC - SAPs is still incomplete and therefore new sampling is necessary to increase the species catalogue.
