Hello, Böhme et al. (2023) argued for the elevation of V. g. caspius and V. g. koniecznyi to full species rank, not only V. g. caspius.
"In addition to the three Middle East species V. griseus, V. nesterovi, and V. caspius, there is also a fourth recent species of this clade, viz. V. koniecznyi Mertens, 1954, an inhabitant of southern Pakistan and northwestern India (Mertens, 1954; Böhme, 2003)."
"The identified areas of their parapatric occurrence in both contact zones argue for full species status of the four recent taxa forming the Psammosaurus clade, next to the distinct morphological differences by which they are distinguished from each other."

It does list it as a full species but is still in the same page as V. griseus.
