Distribution. Known from Sardinia, Cor - sica, Spain and France. Remarks. Blastobasis sardinica sp. nov. seems to belong to widely distributed species in Sardinia, particularly in its 3 northern part, and, with regard to the records in other seaside countries, it is expected to occur more largely also with - in the Mediterranean. On the contrary B. magna is rarer in Sardinia, having the centre of its occurrence probably in Spain. Considering the rather low num - ber of published records from Sardinia 5 (Sinev 2007) I have added further fau - nistic data of this species. The third species of the genus Blastobasis known from Sardinia is B. phycidella which is most prevalent as well as most abundant of the three species, and which creates here a number of individual forms in the colour pattern of wings and the size of adults.
