REMARKS

The identified individuals could be assigned morphologically to Aporrectodea caliginosa meridionalis Bouché, 1972 , which was cited from Corsica by Bouché (1972) together with Ap. caliginosa caliginosa . However, specimens collected in our study were found to be identical to the most widespread clone within lineage II of Aporrectodea trapezoides ( Dugès, 1828) according to their COI sequence ( Fernández et al. 2011). Our work therefore suggests a possible synonymy of Ap. caliginosa meridionalis and Ap. trapezoides , which will have to be confirmed in the future in the light of additional data. Further molecular barcoding of continental populations previously assigned to Ap. caliginosa meridionalis will be necessary to confirm if the synonymy applies to its whole range.
