Coleonyx gypsicolus — JONES & LOVICH 2009
|Distribution||Mexico (Gulf of California: Isla San Marcos)|
Type locality: “Arroyo de la Taneria, Isla San Marcos, Baja California Sur, Mexico.”
|Types||Holotype: BYU 37643|
|Diagnosis||Diagnosis. Coleonyx switaki gypsicolus differs from all other C. switaki in its signiicantly higher mean number of postnasals; eyelid fringe scales; scales a top of head; scales around forearm, body, foreleg, and tail; bright yellow groundcolor, break up of anterior 2-3 black caudal bands to form spots, and prominent vertebral stripe. It differs further from the San Diego and Imperial Co. populations in its significantly higher mean number of precloacal scales and tubercles at midline and larger spots on the regenerated tail. It differs further from the Tres Virgenes populations in its significantly lower mean number of postmentals, significantly higher mean number of gulars, mottled ground color, and less well-defined dorsal spots. It is differentiated further from the San Diego Co. population in its significantly higher mean number of preoculars.|
From the detailed description of the holotype: [...] Neck narrower than body, covered with uniform granular scales with small, sharply pointed and conical tubercles on nape; tubercles on body prominent and conical, long axes directed posteriorly; body tubercles numerous, distributed evenly on dorsum and increasing in size posteriorly from nape to caudal constriction where they terminate; tubercles at caudal constrictions three times larger than those on nape, all exhibiting a sharp and relatively high profile, surrounded by 8-10 and separarated by 2-5 granular scales; average of 41.0 tubercles paravertebrally between centers of limb insertions; strict vertebral row absent. [...]
|Comment||Grismer (1999) elevated gypsicolus to full species status based on scale counts: it has 42-48 eyelid fringe scales versus 32-40 in Coleonyx switaki switaki.|
Abundance: only known from its original description (Meiri et al. 2017).
