Dear All,
In spite of previous identifications, also by me, I have come to the conclusion that this is not Nephrotoma ferruginea but Nephrotoma suturalis wulpiana.
N. ferruginea and N. s. wulpiana are Nearctic species that recently have become known from the south of the Iberian Peninsula (Hancock et al., 2015b on N. ferruginea, and Hancock et al., 2016 on N. s. wulpiana; both papers available as PDF from the CCW (ccw.naturalis.nl)).
N. ferruginea is known from Spain and N. s. wulpiana from Portugal. This is the first record of the latter for Spain.
N. ferruginea has two small spots at the upper side of the lateral thorax (fig. 5 in Oosterbroek 1984, PDF also available). N. s. wulpiana only the upper one (as on the third photo on Diptera-info).
In N. s. wulpiana the posterior end of the mid-dorsal thoracic stripe is darkened and continued into the thoracic suture (as on the first two photos).
All the best,
Pjotr Oosterbroek
