Microlophus peruvianus salinicola (MERTENS 1956)
Tropidurus peruvianus salinicola MERTENS 1956: 108
|Distribution||SW Ecuador, W Peru|
Type locality: Callao and Payta, Peru.
|Reproduction||oviparous. The clutch sizes of northern sample are 3 to 5 (4.1) eggs, salinicola. 2 to 3 (2.3) eggs, and peruvianus, 2 to 5 (3.5) eggs.|
|Types||Holotype: MNHN-RA 6873|
Holotype: SMF 50217, male [salinicola]
|Diagnosis||Diagnosis (genus): Frost 1992: 48.|
Diagnosis. Tropidurus peruvianus is distinguished from members of the occipitalis group by having small, granular dorsolateral scales, rather than large, keeled and imbricate dorsolateral scales. Within the peruvianus group, peruvianus is distinguished from Ihoracicus by the presence of one row of scales between the nostril scale and the first labial and bold black chevrons on the throat in males, rather than two or more rows of scales between the nasal scale and the first labial and no distinct black chevrons on the throat of males; from Iheresiae by the presence of an enlarged vertebral row of scales and the absence of an orange-red eye ring; from tigris by having distinct black throat chevrons in males and small scales on the upper arm without free projecting spines, rather than distinct black, transverse rows of spots on the throat of males and large scales on the upper arm with free projecting spines at the posterior tip.
|Comment||Subspecies: Peters et al. (1970) listed 9 subspecies, many of which have been elevated to full species status since then. The status of salinicola is unclear to us.|
Habitat: rock cliffs, bluffs, outcrops, mud cliffs, salt crust beaches, sand dunes, and sand flats, with or without vegetation.
Type species: Microlophus Lessoni DUMÉRIL & BIBRON 1837 is the type species of the genus Microlophus DUMÉRIL & BIBRON 1837.
|Etymology||The genus is probably named after the (relatively) small (”micro”) spines on the neck and back on this and other species. From Greek “lophos” = neck, hair tuft, tip (or mountain top), (probably) referring to the dorsal spines.|
The species was named after its distribution in Peru.
