Remarks.

The examined male keyed to Pionopsislutescens following Gerecke et al. (2016). The Portuguese specimens form a unique BIN (BOLD:AFV3897). The p-distance between the latter BIN and its nearest neighbor, BOLD:AET1848, which includes specimens of P.lutescens from Montenegro, was estimated at 12.34%, indicating the need for taxonomic revision of P.lutescens complex to identify possible undescribed cryptic species.

Distribution.

Holarctic. In Portugal previously reported from Sintra-Monserrate Park and Palace, Estremadura (Lundblad 1956).
