Rediscovery and redescription of the holotype of Stephanus (Distephanus) [sic!] athesinus Biegeleben, 1929, with comments on its identity and new distributional data for Megischus anomalipes (Förster, 1855) (Hymenoptera, Stephanidae)

The rediscovery of the holotype of Stephanus (Distephanus) [sic!] athesinus Biegeleben, 1929,
preserved in the collections of the Museo di Storia Naturale, Venice (Italy), is recorded together with
a redescription and a comment on its taxonomic identity. Therefore, its synonymy with Megischus
anomalipes (Förster, 1855) is confirmed. New distributional data for M. anomalipes is provided:
it is recorded for the first time from the Italian regions of Veneto, Emilia-Romagna, Tuscany and
Basilicata, and newly recorded from Greece.
