Andrena (Leucandrena) barbilabris (Kirby, 1802)

Distribution: Europe to North America, with scattered European populations south to Spain, Italy, and Greece ( Gusenleitner & Schwarz 2002).

New data: PORTUGAL: Algarve , Carrapateira , 7.iii.2015, 3♂, 3♀, det. Wood, leg. Cross (previously reported in Baldock et al. (2018) as Andrena leptopyga Pérez ); Algarve, Praia da Bordeira, 14.iii.2019, 1♀, det. Wood, leg. A. Soares, P. Garcia Pereira, R. Félix, F. Barros .

Notes: This taxon is known from northern Spain, and so its presence was considered unlikely in southwestern Portugal, and the material from 2015 was confused with A. leptopyga which is present elsewhere in Portugal. The true presence of A. barbilabris in Portugal solves two mysteries, namely the presence of Sphecodes pellucidus Smith, 1845 and Nomada alboguttata Herrich-Schäffer, 1839 , both of which are brood parasites strongly, if not obligately, associated with A. barbilabris ( Bogusch & Straka 2012; Smit 2018). The presence of this seemingly isolated population in the Algarve is surprising, but as N. alboguttata has been reported from the Setúbal peninsula ( Baldock et al. 2018), A. barbilabris is probably more widespread in Portugal but under-recorded due to its early flight period.
