Remarks

The examined specimens of X. maritima mentioned by Schulz & Lymberakis (2006), Schulz & Burkhardt (2012) and Gwiazdowicz et al. (2022) fit the description of this species by Skarżyński et al. (2018). The specimens from the collection of Ellis (1976) that we had at our disposal, despite its poor state of preservation, can also be assigned to this species.

DNA barcoding revealed the existence of two genetic lineages of X. maritma : L1 from Poland and L2 from Crete. Since the analyzed material came from only one site on Crete (Kedros Mountain, Gerakari), it is not possible to further assess the extent of the genetic diversity of X. maritima on this island. More extensive research is needed to determine the barcode lineage status of X. maritima populations worldwide, including in Crete.
