Description :
New occurrence records for two species of Hymenoptera Stephanidae are provided from several states of Europe. Stephanus serrator (Fabricius, 1798) is recorded for the first time for Portugal and with precise locality for Switzerland. Moreover, it is recorded for the first time in the following regions: Navarre (Spain), Wallonia (Belgium), Hesse, Berlin and Bavaria (Germany), Aosta Valley, Lombardy, Veneto, Abruzzo, Campania and Calabria (Italy), and Attica (Greece). Megischus anomalipes (Foerster, 1855) is recorded for the first time in mainland Portugal and Campania (Italy).

Title : New records for crown wasps in Europe (Hymenoptera, Stephanidae)
Abstract : Stephanidae Leach, 1815, is rather small family of Hymenoptera that inlcudes more than 360 extant species (Aguiar, 2004, 2006; van Achterberg and Yang, 2004; Aguiar and Jenning, 2005; van Achterberg and Quicke, 2006; Aguiar et al., 2010; Hong et al., 2010, 2011; Watanabe and van Achterberg, 2014; Tan et al., 2015; Hua-yan et al., 2016; Chen et al., 2016; Moghaddam et al., 2018; Binoy et al., 2020; Gupta and Gawas, 2020; Ge et al., 2021). Although the biology of many species is unknown, stephanids seem to be solitary idiobiont ectoparasitoids of wood boring insect larvae, mainly of Buprestidae and Cerambycidae, but also of Curculionidae, Siricidae, and solitary Apoidea (Aguiar, 2004).
Most such species are in subtropical and tropical areas (Benoit, 1984a, 1984b; Vilhelmsen, 1997; van Achterberg, 2002). Only four species occur in Europe (Hilszczański, 2011): of these, Foenatopus turcomanorum (Semenov, 1891) and Afromegischus gigas (Schletterer, 1889) are known in Europe only on the island of Crete (Hilszczański, 2011). Stephanus serrator (Fabricius, 1798) and Megischus anomalipes (Foerster, 1855) are more widespread on the continent (Madl, 2013) but records are scarce. These latter species can be well-differentiated by photograph because S. serrator has a ventral margin of hind femur with 3 tooth-like processes, while M.anomalipes has two tooth-like processes (Dal Pos & Turrisi, 2017). This note provides several new records of these two species in Europe, increasing faunistic knowledge of this little investigated group of insects.
