Halictus (Seladonia) submediterraneus Pauly, 2015

Distribution: Europe to Turkey and Iran (Pauly et al. 2015).

New data: PORTUGAL: Porto, Leca de Palmeira, 3.viii.1962, 1♂, leg. J. Abraham & L. Horacsek (BMNH; Pauly et al. 2015); Sesimbra, Santana, Estr. Fonte de Carvalho, 3.viii.2019, 1♂, det. & leg. Wood.

Notes: Pauly et al. (2015) separated H. submediterraneus from H. smaragdulus s.s. (Vachal, 1895) on genetic and morphological differences, most clearly in the male genitalia. Halictus submediterraneus was not listed in Baldock et al. (2018) due to uncertainty about how to separate the two taxa. Both species occur in Portugal, but their relative frequency and full distributions are currently unknown as females are morphologically inseparable. In Portugal, confirmed males are currently known only from the west coast.
