Notes.

Revision of Spanish material shows that there is a consistent (if infrequently encountered) population in southern Spain, predominantly in the province of Granada but also in Málaga ( Pauly 2015); populations in northeastern Spain require investigation, as no records post- 1974 are currently available.

Distribution.

Spain (Málaga, Granada, Zaragoza,? Barcelona) ( Warncke 1976, as Nomia femoralis ssp. valga ; Pauly 2015 partim; present study) (Fig. 4 ).
