Description:
<jats:p>New taxonomic, biological and faunistic data are presented for some species of sawflies occurring in southern Europe and North Africa. <jats:italic>Pamphilius mediterraneus</jats:italic><jats:bold>sp. nov.</jats:bold> is described from Italy (Sicily). It belongs to the <jats:italic>alternans</jats:italic> sub-group of the <jats:italic>alternans</jats:italic> species group. <jats:italic>Pristiphora omalos</jats:italic><jats:bold>sp. nov.</jats:bold> is described from Greece (Crete). It belongs to the <jats:italic>depressa</jats:italic> species group. New junior synonyms are <jats:italic>Calameuta tazzekae</jats:italic> Lacourt, 1991 of <jats:italic>Calameuta gaullei</jats:italic> (Konow, 1896), and <jats:italic>Emphytus leucostomus</jats:italic> Costa, 1890 of <jats:italic>Allantus cingulatus</jats:italic> (Scopoli, 1763). <jats:italic>Periclista rufiventris</jats:italic> Zombori, 1979 is moved from the subgenus Periclista to the subgenus Neocharactus. Ametastegia (Protemphytus) persica Khayrandish, Talebi & Blank, 2015 is recorded for the first time in Europe, from Italy (Sicily), and a key to West Palaearctic <jats:italic>Protemphytus</jats:italic> species provided. <jats:italic>Allantus enslini</jats:italic> (Forsius, 1918) is more widespread in southern Europe than previously recorded. An identification key distinguishes it from its closer West Palaearctic relatives. New hostplant records are for <jats:italic>Halidamia affinis</jats:italic> (Fallén, 1807) (<jats:italic>Rubia peregrina</jats:italic>), <jats:italic>Janus compressus</jats:italic> (Fabricius, 1793) (<jats:italic>Sorbus torminalis</jats:italic>), and <jats:italic>Macrophya albicincta</jats:italic> (Schrank, 1776) (<jats:italic>Centranthus ruber</jats:italic>). New distribution records are given for a few other species.</jats:p>
