|Diagnosis||Diagnosis. A Sceloporus of moderate size, maximum snout-vent measurement 81 mm.; shoulder spot faint; scales on posterior surface of thigh about two-thirds size of preanal scales; dorsal scales 29 to 35, average 33.3; ventral scales 45 to 56, average 50.3; scales around body 40 to 48, average 43.7; femoral pores 15 to 19, average 16.8; dorsal scales strongly keeled, strongly mucronate; largest median lateral scales two-thirds size of dorsal scales; ventral scales one-fourth size of dorsal scales; supraoculars irregular; two canthals; anterior section of frontal usually longitudinally divided. Gular region of males immaculate; sides of belly pale blue, not dark-bordered; middle of abdomen light (Smith 1939: 52).|
Color. In males, olive or hair brown above, with a decided bluish tinge mid-dorsally; limbs faintly banded with darker brown; tail with narrow very light gray bands; an indistinct black spot in front of shoulder. Belly mixed pale blue and pearl blue, lighter medially; chest, throat, and ventral surfaces of limbs and tail dingy white, with a tinge of blue; region anterior to gular fold tinged with brown or black, with irregular small light flecks; a median ventral, narrow line on the throat is dingy white. Females similar to males, except for faint, undulate, darker brown bands, about three in number, extending across back; shoulder spots extending upward, separated from each other medially by about three or four scales; belly dingy white, with a bluish tinge; throat darker than belly, with a narrow, lighter, median ventral band two scales wide (Smith 1939: 53).
|Etymology||Named after Latin “asper(a)” = rough, referring to the rough-scaled appearance of the species.|
The Latin obscurus, "dark," or "indistinct," refers to the bluish steel dorsal color, without collar or other markings.
