Stenodynerus fastidiosissimus (de Saussure, 1855)

Material examined.

Malta • 1♀, Imselliet Valley, 5 Jun. 2021, T. Cassar leg.

Notes.

New record for the Maltese Islands. The subspecies Stenodynerus fastidiosissimus laborans (Costa, 1882) was recorded by Erlandsson (1972), though it is highly likely that this was on the basis of misidentified specimens (see discussion below). Without examining Erlandsson’s specimens it is not possible to know if they truly correspond to the typical form of S. fastidiosissimus, as does the material mentioned above, or if they belong to some other taxon. The distribution of the nominal subspecies includes North Africa and Southern Europe (Gusenleitner 2000a).
