Sartène-Granace. gall No. 3, 28.V.95, 1 ♀. Material deposited in UB.

REMARKS

These specimens are more robust than typical P. cardiguensis , but we have not found any significant morphological differences and therefore we consider them conspecific with P. cardiguensis even though the galls are located in a different place and on a different host (on thin branches of Q. suber rather than on catkins of Q. ilex ) than those of typical P. cardiguensis .
