Psammodromus occidentalis — SPEYBROECK et al. 2020
|Distribution||W Spain, Portugal (P. Fitze, pers. comm.)|
Type locality: Colmenar del Arroyo (Madrid, Spain, 40° 27’ 22.14’’N, 4° 10’ 28.36’’W)
|Types||Holotype: MNCN/ ADN 34516, adult male captured on 24 October 2008 by Patrick S. Fitze and Virginia Gonzalez-Jimena|
|Diagnosis||Diagnosis. Psammodromus occidentalis sp. n. shows 20–29 ventral scale rows, no supralabial scale below the subocular scale, 15–26 throat scales, 0– 3 collar scales, 9–15 femoral pores, a snout shape of 0.96–2.51, 0–5 ocelli, and a nuptial coloration score of 0–4. It can be distinguished from the edwardsianus lineage by the absence of a supralabial scale below the subocular scale, lower femoral pore numbers, more extended nuptial coloration, and slightly bigger snout shape values, and from the Central lineage (P. hispanicus) by bigger snout shape values, corresponding to a less pointed snout, higher number of femoral pores, and higher number of ocelli. Molecular differentiation based on mitochondrial and the nuclear datasets shows that P. occidentalis sp. n. is more distant from the edwardsianus and Central lineage than the later two from each other. Psammodromus occidentalis sp. n. can be easily distinguished from P. algirus by the smaller body size, a shorter tail length that rarely exceeds 2 x SVL (in adult individuals with intact tail: mean = 1.5 x ± 0.02; range = 0.7 – 2.4; P. algirus > 2 x SVL, Böhme 1981), absence of pterygoid teeth (Arnold 1989), presence of a gular fold and distinct collar scales, absence of imbricated and pointed ventral scales, and presence of two central ventral rows of clearly narrower scales compared to scales of adjoining rows. Psammodromus occidentalis sp. n. differs from P. blanci by a clearly present gular fold, absence of imbricate or rounded ventral scales, two nar- rower central ventral rows (compared to the adjoining ventral rows), by rarely existing solid lateral lines, and by a brown grayish dorsal ground color (Schleich et al. 1996). It differs from P. microdactylus by the presence of a gular fold, distinct collar scales, a brown grayish dorsal ground color, two dashed lateral lines, absence of pointed or rounded central ventral rows, presence of two narrower central ventral rows, and absence of greenish or dark olive dorsal ground color (Schleich et al. 1996) [from FITZE et al. 2012].|
|Comment||This species was previously considered as the western lineage of P. hispanicus (Fitze et al. 2011).|
|Etymology||The species epithet refers to the geographical distribution of this lizard. All described populations are located on the Western Iberian Peninsula.|
